The reboot quirk for ASUS EeeBook X205TA contains a typo in
DMI_PRODUCT_NAME, improperly referring to X205TAW instead of
X205TA, which prevents the quirk from being triggered. The
model X205TAW already has a reboot quirk of its own.
This fix simply removes the inappropriate final letter W.

platform/x86: asus-wmi: Detect quirk_no_rfkill from the DSDT
[ Upstream commit
71050ae7bf83e4d71a859257d11adc5de517073e ]
Some Asus laptops that have an airplane-mode indicator LED, also have
the WMI WLAN user bit set, and the following bits in their DSDT:
Scope (_SB)
{
(...)
Device (ATKD)
{
(...)
Method (WMNB, 3, Serialized)
{
(...)
If (LEqual (IIA0, 0x00010002))
{
OWGD (IIA1)
Return (One)
}
}
}
}
So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.
This commit skips registering RFKill switches at all for these laptops,
to allow the asus-wireless driver to drive the airplane mode LED
correctly through the ASHS ACPI device. Relying on the presence of ASHS
and ASUS_WMI_DSTS_USER_BIT avoids adding DMI-based quirks for at least
21 different laptops.

By referencing Intel Platform Controller Hub(PCH) datasheet,
the xHC USB 2.0 Port Routing(XUSB2PR) at offset 0xD0-0xD3h

watchdog: s3c2410: Fix infinite interrupt in soft mode
[ Upstream commit
0b445549ea6f91ffea78a976fe89b932db6e077a ]
In soft (no-reboot) mode, the driver self-pings watchdog upon expiration
of an interrupt. However the interrupt itself was not cleared thus on
first hit, the system enters infinite interrupt handling loop.
On Odroid U3 (Exynos4412), when booted with s3c2410_wdt.soft_noboot=1
argument the console is flooded:
# killall -9 watchdog
[ 60.523760] s3c2410-wdt
10060000.watchdog: watchdog timer expired (irq)
[ 60.536744] s3c2410-wdt
10060000.watchdog: watchdog timer expired (irq)
Fix this by writing something to the WTCLRINT register to clear the
interrupt. The register WTCLRINT however appeared in S3C6410 so a new
watchdog quirk and flavor are needed.

PCI: Add ACS quirk for Qualcomm QDF2400 and QDF2432
[ Upstream commit
33be632b8443b6ac74aa293504f430604fb9abeb ]
The Qualcomm QDF2xxx root ports don't advertise an ACS capability, but they
do provide ACS-like features to disable peer transactions and validate bus
numbers in requests.
To be specific:
* Hardware supports source validation but it will report the issue as
Completer Abort instead of ACS Violation.
* Hardware doesn't support peer-to-peer and each root port is a root
complex with unique segment numbers.
* It is not possible for one root port to pass traffic to the other root
port. All PCIe transactions are terminated inside the root port.
Add an ACS quirk for the QDF2400 and QDF2432 products.

mmc: sdhci-of-esdhc: remove default broken-cd for ARM
[ Upstream commit
e9acc77dd046b22c7ebf70e35f68968978445f8b ]
Initially all QorIQ platforms were PowerPC architecture and they didn't
support card detection except several platforms. The driver added the
quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION as default and this made broken-cd
property in dts node didn't work. Now QorIQ platform turns to ARM
architecture and most of them could support card detection. However it's
a large number of dts trees that need to be fixed with broken-cd if we
remove the default SDHCI_QUIRK_BROKEN_CARD_DETECTION in driver. And the
users don't want to see this. So this patch is to remove this default
quirk just for ARM and keep it for PowerPC.(Note, QorIQ PowerPC platform
only has big-endian eSDHC while QorIQ ARM platform has big-endian or
little-endian eSDHC) This makes broken-cd property work again for ARM.

PCI: Add Broadcom Northstar2 PAXC quirk for device class and MPSS
[ Upstream commit
ce709f86501a013e941e9986cb072eae375ddf3e ]
The Broadcom Northstar2 SoC has a number of quirks for the PAXC
(internal/fake) PCI bus. Specifically, the PCI config space is shared
between the root port and the first PF (ie., PF0), and a number of fields
are tied to zero (thus preventing them from being set). These cannot be
"fixed" in device firmware, so we must fix them with a quirk.

This patch adds a Qualcomm specific quirk to the arm_smccc_smc call.
On Qualcomm ARM64 platforms, the SMC call can return before it has
completed. If this occurs, the call can be restarted, but it requires
using the returned session ID value from the interrupted SMC call.
The quirk stores off the session ID from the interrupted call in the

ACPI / button: Change default behavior to lid_init_state=open
[ Upstream commit
77e9a4aa9de10cc1418bf9a892366988802a8025 ]
More and more platforms need the button.lid_init_state=open quirk. This
patch sets it the default behavior.
If a platform doesn't send lid open event or lid open event is lost due to
the underlying system problems, then we can compare various combinations:
1. systemd/acpid is used to suspend system or not, systemd has a special
logic forcing open event after resuming;
2. _LID returns a cached value or not.
The result is as follows:
1. lid_init_state=method
1. cached
1. resumed by lid:
(x) event=close
(x) systemd=suspends again
(x) acpid=suspends again
(x) state=close
2. resumed by other:
(o) event=close
(x) systemd=suspends again
(x) acpid=suspends again
(o) state=close
2. non-cached
1. resumed by lid:
(o) event=open
(o) systemd=resumes
(o) acpid=resumes
(o) state=open
2. resumed by other:
(o) event=close
(x) systemd=suspends again
(x) acpid=suspends again
(o) state=close
2. lid_init_state=open
1. cached
1. resumed by lid:
(o) event=open
(o) systemd=resumes
(o) acpid=resumes
(x) state=close
2. resumed by other:
(x) event=open
(o) systemd=resumes
(o) acpid=resumes
(o) state=close
2. non-cached
1. resumed by lid:
(o) event=open
(o) systemd=resumes
(o) acpid=resumes
(o) state=open
2. resumed by other:
(x) event=open
(o) systemd=resumes
(o) acpid=resumes
(o) state=close
3. lid_init_state=ignore
1. cached
1. resumed by lid:
(o) event=none
(x) systemd=suspends again
(o) acpid=resumes
(x) state=close
2. resumed by other:
(o) event=none
(x) systemd=suspends again
(o) acpid=resumes
(o) state=close
2. non-cached
1. resumed by lid:
(o) event=none
(x) systemd=suspends again
(o) acpid=resumes
(o) state=open
2. resumed by other:
(o) event=none
(x) systemd=suspends again
(o) acpid=resumes
(o) state=close
As a conclusion:
1. With systemd changed, lid_init_state=ignore has only one problem and the
problem comes from an underlying issue, not userspace and kernel lid
handling.
2. Without systemd changed, lid_init_state=open can be the default
behavior as the pass ratio is not much worse than lid_init_state=ignore.
3. lid_init_state=method is buggy, we can have a separate patch to make it
deprectated.

usb: chipidea: msm: Rely on core to override AHBBURST
[ Upstream commit

The core framework already handles setting this parameter with a
platform quirk. Add the appropriate flag so that we always set
AHBBURST to 0. Technically DT should be doing this, but we always
do it for msm chipidea devices so setting the flag in the driver
works just as well. If the burst needs to be anything besides 0,
we expect the 'ahb-burst-config' dts property to be present.

drm/i915: actually drive the BDW reserved IDs
[ Upstream commit
98b2f01c8dfc8922a2af1fe82a1c40cac4911634 ]
Back in 2014, commit
fb7023e0e248 ("drm/i915: BDW: Adding Reserved PCI
IDs.") added the reserved PCI IDs in order to try to make sure we had
working drivers in case we ever released products using these IDs
(since we had instances of this type of problem in the past). The
problem is that the patch only touched the macros used by
early-quirks.c and by the user space components that rely on
i915_pciids.h, it didn't touch the macros used by i915_pci.c. So we
correctly handled the stolen memory for these theoretical IDs, but we
didn't actually drive the devices from i915.ko.
So this patch fixes the original commit by actually making i915.ko
drive these IDs, which was the goal. There's no information on what
would be the GT count on these IDs, so we just go with the safer
intel_broadwell_info, at the risk of ignoring a possibly inexistent
BSD2_RING.
I did some checking, and it seems that these IDs are driven by
intel-gpu-tools, xf86-video-intel and libdrm (since they contain old
copies of i915_pciids.h), but they are not checked by mesa.
The alternative to this patch would be to just assume we're actually
never going to use these IDs, and then remove them from our ID lists
and make sure our user space components sync the latest i915_pciids.h
copy. I'm fine with either approaches, as long as we make sure that
every component tries to drive the same list of PCI IDs.

ACPI / sysfs: Provide quirk mechanism to prevent GPE flooding
[ Upstream commit
9c4aa1eecb48cfac18ed5e3aca9d9ae58fbafc11 ]
Sometimes, the users may require a quirk to be provided from ACPI subsystem
core to prevent a GPE from flooding.
Normally, if a GPE cannot be dispatched, ACPICA core automatically prevents
the GPE from firing. But there are cases the GPE is dispatched by _Lxx/_Exx
provided via AML table, and OSPM is lacking of the knowledge to get
_Lxx/_Exx correctly executed to handle the GPE, thus the GPE flooding may
still occur.
The existing quirk mechanism can be enabled/disabled using the following
commands to prevent such kind of GPE flooding during runtime:
# echo mask > /sys/firmware/acpi/interrupts/gpe00
# echo unmask > /sys/firmware/acpi/interrupts/gpe00
To avoid GPE flooding during boot, we need a boot stage mechanism.
This patch provides such a boot stage quirk mechanism to stop this kind of
GPE flooding. This patch doesn't fix any feature gap but since the new
feature gaps could be found in the future endlessly, and can disappear if
the feature gaps are filled, providing a boot parameter rather than a DMI
table should suffice.

we can't rely on the PCI VID:DID to tell use how to decode the field
we reserved for this as the stripe size so we need to do something else
for the list of devices using this quirk.
The field was supposed to allow flexibility on the device's back-end
striping, but it turned out that never materialized; the chunk is always
the same as MDTS in the products subscribing to this quirk, so this
patch removes the stripe_size field and sets the chunk to the max hw

The AMW0_GUID1 wmi is not only found on Acer family but also other

Currently we use one shared global acpi_pci_root_ops structure to keep
controller-specific ops. We pass its pointer to acpi_pci_root_create() and
associate it with a host bridge instance for good. Such a design implies
serious drawback. Any potential manipulation on the single system-wide
acpi_pci_root_ops leads to kernel crash. The structure content is not
really changing even across multiple host bridges creation; thus it was not
an issue so far.
In preparation for adding ECAM quirks mechanism (where controller-specific
PCI ops may be different for each host bridge) allocate new
acpi_pci_root_ops and fill in with data for each bridge. Now it is safe to
have different controller-specific info. As a consequence free
acpi_pci_root_ops when host bridge is released.

svcauth_gss: Close connection when dropping an incoming message
[ Upstream commit
4d712ef1db05c3aa5c3b690a50c37ebad584c53f ]
S5.3.3.1 of RFC 2203 requires that an incoming GSS-wrapped message
whose sequence number lies outside the current window is dropped.
The rationale is:
The reason for discarding requests silently is that the server
is unable to determine if the duplicate or out of range request
was due to a sequencing problem in the client, network, or the
operating system, or due to some quirk in routing, or a replay
attack by an intruder. Discarding the request allows the client
to recover after timing out, if indeed the duplication was
unintentional or well intended.
However, clients may rely on the server dropping the connection to
indicate that a retransmit is needed. Without a connection reset, a
client can wait forever without retransmitting, and the workload
just stops dead. I've reproduced this behavior by running xfstests
generic/323 on an NFSv4.0 mount with proto=rdma and sec=krb5i.
To address this issue, have the server close the connection when it
silently discards an incoming message due to a GSS sequence number
problem.
There are a few other places where the server will never reply.
Change those spots in a similar fashion.

There is no reasons to filter out keyboard and consumer control collections
in hid-multitouch.
With the previous hid-input fix, there is now a full support of the Type
Cover and we can remove all specific bits from hid-core and hid-microsoft.
hid-multitouch will automatically set HID_QUIRK_NO_INIT_REPORTS so we can
also remove it from the list of ushbid quirks.

clk: lpc32xx: add a quirk for PWM and MS clock dividers
[ Upstream commit
f84d42a9cffc4ecd96f1ce3a038f841782142eb2 ]
In common clock framework CLK_DIVIDER_ONE_BASED or'ed with
CLK_DIVIDER_ALLOW_ZERO flags indicates that
1) a divider clock may be set to zero value,
2) divider's zero value is interpreted as a non-divided clock.
On the LPC32xx platform clock dividers of PWM and memory card clocks
comply with the first condition, but zero value means a gated clock,
thus it may happen that the divider value is not updated when
the clock is enabled and the clock remains gated.
The change adds one-shot quirks, which check for zero value of divider
on initialization and set it to a non-zero value, therefore in runtime
a gate clock will work as expected.

random: use chacha20 for get_random_int/long
commit
f5b98461cb8167ba362ad9f74c41d126b7becea7 upstream.
Now that our crng uses chacha20, we can rely on its speedy
characteristics for replacing MD5, while simultaneously achieving a
higher security guarantee. Before the idea was to use these functions if
you wanted random integers that aren't stupidly insecure but aren't
necessarily secure either, a vague gray zone, that hopefully was "good
enough" for its users. With chacha20, we can strengthen this claim,
since either we're using an rdrand-like instruction, or we're using the
same crng as /dev/urandom. And it's faster than what was before.
We could have chosen to replace this with a SipHash-derived function,
which might be slightly faster, but at the cost of having yet another
RNG construction in the kernel. By moving to chacha20, we have a single
RNG to analyze and verify, and we also already get good performance
improvements on all platforms.
Implementation-wise, rather than use a generic buffer for both
get_random_int/long and memcpy based on the size needs, we use a
specific buffer for 32-bit reads and for 64-bit reads. This way, we're
guaranteed to always have aligned accesses on all platforms. While
slightly more verbose in C, the assembly this generates is a lot
simpler than otherwise.
Finally, on 32-bit platforms where longs and ints are the same size,
we simply alias get_random_int to get_random_long.

MIPS: Flush wrong invalid FTLB entry for huge page
commit
0115f6cbf26663c86496bc56eeea293f85b77897 upstream.
On VTLB+FTLB platforms (such as Loongson-3A R2), FTLB's pagesize is
usually configured the same as PAGE_SIZE. In such a case, Huge page
entry is not suitable to write in FTLB.
Unfortunately, when a huge page is created, its page table entries
haven't created immediately. Then the TLB refill handler will fetch an
invalid page table entry which has no "HUGE" bit, and this entry may be
written to FTLB. Since it is invalid, TLB load/store handler will then
use tlbwi to write the valid entry at the same place. However, the
valid entry is a huge page entry which isn't suitable for FTLB.
Our solution is to modify build_huge_handler_tail. Flush the invalid
old entry (whether it is in FTLB or VTLB, this is in order to reduce
branches) and use tlbwr to write the valid new entry.

MIPS: Check TLB before handle_ri_rdhwr() for Loongson-3
commit
5a34133167dce36666ea054e30a561b7f4413b7f upstream.
Loongson-3's micro TLB (ITLB) is not strictly a subset of JTLB. That
means: when a JTLB entry is replaced by hardware, there may be an old
valid entry exists in ITLB. So, a TLB miss exception may occur while
handle_ri_rdhwr() is running because it try to access EPC's content.
However, handle_ri_rdhwr() doesn't clear EXL, which makes a TLB Refill
exception be treated as a TLB Invalid exception and tlbp may fail. In
this case, if FTLB (which is usually set-associative instead of set-
associative) is enabled, a tlbp failure will cause an invalid tlbwi,
which will hang the whole system.
This patch rename handle_ri_rdhwr_vivt to handle_ri_rdhwr_tlbp and use
it for Loongson-3. It try to solve the same problem described as below,
but more straightforwards.
https://patchwork.linux-mips.org/patch/12591/
I think Loongson-2 has the same problem, but it has no FTLB, so we just
keep it as is.

MIPS: Force o32 fp64 support on 32bit MIPS64r6 kernels
commit
2e6c7747730296a6d4fd700894286db1132598c4 upstream.
When a 32-bit kernel is configured to support MIPS64r6 (CPU_MIPS64_R6),
MIPS_O32_FP64_SUPPORT won't be selected as it should be because
MIPS32_O32 is disabled (o32 is already the default ABI available on
32-bit kernels).
This results in userland FP breakage as CP0_Status.FR is read-only 1
since r6 (when an FPU is present) so __enable_fpu() will fail to clear
FR. This causes the FPU emulator to get used which will incorrectly
emulate 32-bit FPU registers.
Force o32 fp64 support in this case by also selecting
MIPS_O32_FP64_SUPPORT from CPU_MIPS64_R6 if 32BIT.

s390/uaccess: get_user() should zero on failure (again)
commit

Commit
fd2d2b191fe7 ("s390: get_user() should zero on failure")
intended to fix s390's get_user() implementation which did not zero
the target operand if the read from user space faulted. Unfortunately
the patch has no effect: the corresponding inline assembly specifies
that the operand is only written to ("=") and the previous value is
discarded.
Therefore the compiler is free to and actually does omit the zero
initialization.
To fix this simply change the contraint modifier to "+", so the
compiler cannot omit the initialization anymore.

s390/decompressor: fix initrd corruption caused by bss clear
commit

Reorder the operations in decompress_kernel() to ensure initrd is moved
to a safe location before the bss section is zeroed.
During decompression bss can overlap with the initrd and this can
corrupt the initrd contents depending on the size of the compressed
kernel (which affects where the initrd is placed by the bootloader) and
the size of the bss section of the decompressor.
Also use the correct initrd size when checking for overlaps with
parmblock.

xtensa: make __pa work with uncached KSEG addresses
commit
2b83878dd74a7c73bedcb6600663c1c46836e8af upstream.
When __pa is applied to virtual address in uncached KSEG region the
result is incorrect. Fix it by checking if the original address is in
the uncached KSEG and adjusting the result. It looks better than masking
off bits because pfn_valid would correctly work with new __pa results
and it may be made working in noMMU case, once we get definition for
uncached memory view.
This is required for the dma_common_mmap and DMA debug code to work
correctly: they both indirectly use __pa with coherent DMA addresses.
In case of DMA debug the visible effect is false reports that an address
mapped for DMA is accessed by CPU.

dm raid: fix NULL pointer dereference for raid1 without bitmap

Commit 4257e08 ("dm raid: support to change bitmap region size")
introduced a bitmap resize call during preresume phase. User can create
a DM device with "raid" target configured as raid1 with no metadata
devices to hold superblock/bitmap info. It can be achieved using the

The raid_preresume() function incorrectly assumes that the raid_set has
a bitmap enabled if RT_FLAG_RS_BITMAP_LOADED is set. But
RT_FLAG_RS_BITMAP_LOADED is getting set in __load_dirty_region_bitmap()
even if there is no bitmap present (and bitmap_load() happily returns 0
even if a bitmap isn't present). So the only way forward in the
near-term is to check if the bitmap is present by seeing if
mddev->bitmap is not NULL after bitmap_load() has been called.
By doing so the above NULL pointer is avoided.

It used to be sufficient just to call pagefault_disable(), because that
also disabled preemption. But the two were decoupled in commit
8222dbe21e79
("sched/preempt, mm/fault: Decouple preemption from the page fault
logic") in mid 2015.
So add the missing preempt_disable/enable(). We should also call
disable_kernel_fp(), although it does nothing by default, there is a
debug switch to make it active and all enables should be paired with
disables.

powerpc: Don't try to fix up misaligned load-with-reservation instructions
commit
48fe9e9488743eec9b7c1addd3c93f12f2123d54 upstream.
In the past, there was only one load-with-reservation instruction,
lwarx, and if a program attempted a lwarx on a misaligned address, it
would take an alignment interrupt and the kernel handler would emulate
it as though it was lwzx, which was not really correct, but benign since
it is loading the right amount of data, and the lwarx should be paired
with a stwcx. to the same address, which would also cause an alignment
interrupt which would result in a SIGBUS being delivered to the process.
We now have 5 different sizes of load-with-reservation instruction. Of
those, lharx and ldarx cause an immediate SIGBUS by luck since their
entries in aligninfo[] overlap instructions which were not fixed up, but
lqarx overlaps with lhz and will be emulated as such. lbarx can never
generate an alignment interrupt since it only operates on 1 byte.
To straighten this out and fix the lqarx case, this adds code to detect
the l[hwdq]arx instructions and return without fixing them up, resulting
in a SIGBUS being delivered to the process.

powerpc/64: Fix flush_(d|i)cache_range() called from modules
commit
8f5f525d5b83f7d76a6baf9c4e94d4bf312ea7f6 upstream.
When the kernel is compiled to use 64bit ABIv2 the _GLOBAL() macro does
not include a global entry point. A function's global entry point is
used when the function is called from a different TOC context and in the
kernel this typically means a call from a module into the vmlinux (or
vice-versa).
There are a few exported asm functions declared with _GLOBAL() and
calling them from a module will likely crash the kernel since any TOC
relative load will yield garbage.
flush_icache_range() and flush_dcache_range() are both exported to
modules, and use the TOC, so must use _GLOBAL_TOC().

powerpc: Disable HFSCR[TM] if TM is not supported
commit
7ed23e1bae8bf7e37fd555066550a00b95a3a98b upstream.
On Power8 & Power9 the early CPU inititialisation in __init_HFSCR()
turns on HFSCR[TM] (Hypervisor Facility Status and Control Register
[Transactional Memory]), but that doesn't take into account that TM
might be disabled by CPU features, or disabled by the kernel being built
with CONFIG_PPC_TRANSACTIONAL_MEM=n.
So later in boot, when we have setup the CPU features, clear HSCR[TM] if
the TM CPU feature has been disabled. We use CPU_FTR_TM_COMP to account
for the CONFIG_PPC_TRANSACTIONAL_MEM=n case.
Without this a KVM guest might try use TM, even if told not to, and
cause an oops in the host kernel. Typically the oops is seen in
__kvmppc_vcore_entry() and may or may not be fatal to the host, but is
always bad news.
In practice all shipping CPU revisions do support TM, and all host
kernels we are aware of build with TM support enabled, so no one should
actually be able to hit this in the wild.
