null_blk: Fix scheduling in atomic with zoned mode
Commit
aa1c09cb65e2 ("null_blk: Fix locking in zoned mode") changed
zone locking to using the potentially sleeping wait_on_bit_io()
function. This is acceptable when memory backing is enabled as the
device queue is in that case marked as blocking, but this triggers a
scheduling while in atomic context with memory backing disabled.
Fix this by relying solely on the device zone spinlock for zone
information protection without temporarily releasing this lock around
null_process_cmd() execution in null_zone_write(). This is OK to do
since when memory backing is disabled, command processing does not
block and the memory backing lock nullb->lock is unused. This solution
avoids the overhead of having to mark a zoned null_blk device queue as
blocking when memory backing is unused.
This patch also adds comments to the zone locking code to explain the
unusual locking scheme.
Fixes:

In this situation, the bios_event_log pointer in the tpm_bios_log struct
was not NULL but was equal to the ZERO_SIZE_PTR (0x10) value. This was
due to the following kmemdup() in tpm_read_log_efi():
int tpm_read_log_efi(struct tpm_chip *chip)
{
...
/* malloc EventLog space */
log->bios_event_log = kmemdup(log_tbl->log, log_size, GFP_KERNEL);
if (!log->bios_event_log) {
ret = -ENOMEM;
goto out;
}
...
}
When log_size is zero, due to an empty event log from firmware,
ZERO_SIZE_PTR is returned from kmemdup(). Upon a read of the
binary_bios_measurements file, the tpm2_bios_measurements_start()
function does not perform a ZERO_OR_NULL_PTR() check on the
bios_event_log pointer before dereferencing it.
Rather than add a ZERO_OR_NULL_PTR() check in functions that make use of
the bios_event_log pointer, simply avoid creating the
binary_bios_measurements_file as is done in other event log retrieval
backends.
Explicitly ignore all of the events in the final event log when the main
event log is empty. The list of events in the final event log cannot be
accurately parsed without referring to the first event in the main event
log (the event log header) so the final event log is useless in such a
situation.

tpm_tis: Disable interrupts on ThinkPad T490s
There is a misconfiguration in the bios of the gpio pin used for the
interrupt in the T490s. When interrupts are enabled in the tpm_tis
driver code this results in an interrupt storm. This was initially
reported when we attempted to enable the interrupt code in the tpm_tis
driver, which previously wasn't setting a flag to enable it. Due to
the reports of the interrupt storm that code was reverted and we went back
to polling instead of using interrupts. Now that we know the T490s problem
is a firmware issue, add code to check if the system is a T490s and
disable interrupts if that is the case. This will allow us to enable
interrupts for everyone else. If the user has a fixed bios they can
force the enabling of interrupts with tpm_tis.interrupts=1 on the
kernel command line.

i2c: designware: slave should do WRITE_REQUESTED before WRITE_RECEIVED
Sometimes we would get the following flow when doing an i2cset:
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
I2C_SLAVE_WRITE_RECEIVED
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x714 : INTR_STAT=0x204
I2C_SLAVE_WRITE_REQUESTED
I2C_SLAVE_WRITE_RECEIVED
Documentation/i2c/slave-interface.rst says that I2C_SLAVE_WRITE_REQUESTED,
which is mandatory, should be sent while the data did not arrive yet. It
means in a write-request I2C_SLAVE_WRITE_REQUESTED should be reported
before any I2C_SLAVE_WRITE_RECEIVED.
By the way, I2C_SLAVE_STOP didn't be reported in the above case because
DW_IC_INTR_STAT was not 0x200.
dev->status can be used to record the current state, especially Designware
I2C controller has no interrupts to identify a write-request. This patch
makes not only I2C_SLAVE_WRITE_REQUESTED been reported first when
IC_INTR_RX_FULL is rising and dev->status isn't STATUS_WRITE_IN_PROGRESS
but also I2C_SLAVE_STOP been reported when a STOP condition is received.

RISC-V: Fix the VDSO symbol generaton for binutils-2.35+
We were relying on GNU ld's ability to re-link executable files in order
to extract our VDSO symbols. This behavior was deemed a bug as of
binutils-2.35 (specifically the binutils-gdb commit
a87e1817a4 ("Have
the linker fail if any attempt to link in an executable is made."), but
as that has been backported to at least Debian's binutils-2.34 in may
manifest in other places.
The previous version of this was a bit of a mess: we were linking a
static executable version of the VDSO, containing only a subset of the
input symbols, which we then linked into the kernel. This worked, but
certainly wasn't a supported path through the toolchain. Instead this
new version parses the textual output of nm to produce a symbol table.
Both rely on near-zero addresses being linkable, but as we rely on weak
undefined symbols being linkable elsewhere I don't view this as a major
issue.

CLONE_CHILD_SETTID.
Further inspection showed that the put_user() in schedule_tail() was
missing entirely, the store not emitted by the compiler.

Notice there are no stores other than to the stack. There should be a
stw in there for the store to current->set_child_tid.
This is only seen with GCC 4.9 era compilers (tested with 4.9.3 and
4.9.4), and only when CONFIG_PPC_KUAP is disabled.
When CONFIG_PPC_KUAP=y, the inline asm that's part of the isync()
and mtspr() inlined via allow_user_access() seems to be enough to
avoid the bug.
We already have a macro to work around this (or a similar bug), called
asm_volatile_goto which includes an empty asm block to tickle the
compiler into generating the right code. So use that.
With this applied the code generation looks more like it will work:

ceph: check session state after bumping session->s_seq
Some messages sent by the MDS entail a session sequence number
increment, and the MDS will drop certain types of requests on the floor
when the sequence numbers don't match.
In particular, a REQUEST_CLOSE message can cross with one of the
sequence morphing messages from the MDS which can cause the client to
stall, waiting for a response that will never come.
Originally, this meant an up to 5s delay before the recurring workqueue
job kicked in and resent the request, but a recent change made it so
that the client would never resend, causing a 60s stall unmounting and
sometimes a blockisting event.
Add a new helper for incrementing the session sequence and then testing
to see whether a REQUEST_CLOSE needs to be resent, and move the handling
of CEPH_MDS_SESSION_CLOSING into that function. Change all of the
bare sequence counter increments to use the new helper.

PCI: mvebu: Fix duplicate resource requests
With commit
669cbc708122 ("PCI: Move DT resource setup into
devm_pci_alloc_host_bridge()"), the DT 'ranges' is parsed and populated
into resources when the host bridge is allocated. The resources are
requested as well, but that happens a second time for the mvebu driver in
mvebu_pcie_parse_request_resources(). We should only be requesting the
additional resources added in mvebu_pcie_parse_request_resources(). These
are not added by default because they use custom properties rather than
standard DT address translation.
Also, the bus ranges was also populated by default, so we can remove it
from mvebu_pci_host_probe().

PCI: dwc: Restore ATU memory resource setup to use last entry
Prior to commit
0f71c60ffd26 ("PCI: dwc: Remove storing of PCI resources"),
the DWC driver was setting up the last memory resource rather than the
first memory resource. This doesn't matter for most platforms which only
have 1 memory resource, but it broke Tegra194 which has a 2nd
(prefetchable) memory region that requires an ATU entry. The first region
on Tegra194 relies on the default 1:1 pass-thru of outbound transactions
and doesn't need an ATU entry.

====================
pull-request: can 2020-11-03
The first two patches are by Oleksij Rempel and they add a generic
can-controller Device Tree yaml binding and convert the text based binding
of the flexcan driver to a yaml based binding.
Zhang Changzhong's patch fixes a remove_proc_entry warning in the AF_CAN
core.
A patch by me fixes a kfree_skb() call from IRQ context in the rx-offload
helper.
Vincent Mailhol contributes a patch to prevent a call to kfree_skb() in
hard IRQ context in can_get_echo_skb().
Oliver Hartkopp's patch fixes the length calculation for RTR CAN frames
in the __can_get_echo_skb() helper.
Oleksij Rempel's patch fixes a use-after-free that shows up with j1939 in
can_create_echo_skb().
Yegor Yefremov contributes 4 patches to enhance the j1939 documentation.
Zhang Changzhong's patch fixes a hanging task problem in j1939_sk_bind()
if the netdev is down.
Then there are three patches for the newly added CAN_ISOTP protocol. Geert
Uytterhoeven enhances the kconfig help text. Oliver Hartkopp's patch adds
missing RX timeout handling in listen-only mode and Colin Ian King's patch
decreases the generated object code by 926 bytes.
Zhang Changzhong contributes a patch for the ti_hecc driver that fixes the
error path in the probe function.
Navid Emamdoost's patch for the xilinx_can driver fixes the error handling
in case of failing pm_runtime_get_sync().
There are two patches for the peak_usb driver. Dan Carpenter adds range
checking in decode operations and Stephane Grosjean's patch fixes
a timestamp wrapping problem.
Stephane Grosjean's patch for th peak_canfd driver fixes echo management if
loopback is on.
The next three patches all target the mcp251xfd driver. The first one is
by me and it increased the severity of CRC read error messages. The kernel
test robot removes an unneeded semicolon and Tom Rix removes unneeded
break in several switch-cases.
The last 4 patches are by Joakim Zhang and target the flexcan driver,
the first three fix ECC related device specific quirks for the LS1021A,
LX2160A and the VF610 SoC. The last patch disable wakeup completely upon
driver remove.

ARM, xtensa: highmem: avoid clobbering non-page aligned memory reservations
free_highpages() iterates over the free memblock regions in high
memory, and marks each page as available for the memory management
system.
Until commit
cddb5ddf2b76 ("arm, xtensa: simplify initialization of
high memory pages") it rounded beginning of each region upwards and end of
each region downwards.
However, after that commit free_highmem() rounds the beginning and end of
each region downwards, and we may end up freeing a page that is
memblock_reserve()d, resulting in memory corruption.
Restore the original rounding of the region boundaries to avoid freeing
reserved pages.
Fixes:
