Pull printk updates from Petr Mladek:
- Add Petr Mladek, Sergey Senozhatsky as printk maintainers, and Steven
Rostedt as the printk reviewer. This idea came up after the
discussion about printk issues at Kernel Summit. It was formulated
and discussed at lkml[1].
- Extend a lock-less NMI per-cpu buffers idea to handle recursive
printk() calls by Sergey Senozhatsky[2]. It is the first step in
sanitizing printk as discussed at Kernel Summit.
The change allows to see messages that would normally get ignored or
would cause a deadlock.
Also it allows to enable lockdep in printk(). This already paid off.
The testing in linux-next helped to discover two old problems that
were hidden before[3][4].
- Remove unused parameter by Sergey Senozhatsky. Clean up after a past
change.

seccomp: Only dump core when single-threaded
The SECCOMP_RET_KILL filter return code has always killed the current
thread, not the entire process. Changing this as a side-effect of dumping
core isn't a safe thing to do (a few test suites have already flagged this
behavioral change). Instead, restore the RET_KILL semantics, but still
dump core when a RET_KILL delivers SIGSYS to a single-threaded process.

- The ability for a guest to ask the hypervisor to resize the guest's

memory is hotplugged into/out-of the guest. This allows the hash
table to be sized based on the current memory usage of the guest,

Pull pin control updates from Linus Walleij:
"Pin control bulk changes for the v4.11 kernel cycle.
Core changes:
- Switch the generic pin config argument from 16 to 24 bits, only use
8 bits for the configuration type. We might need to encode more
information about a certain setting than we need to encode
different generic settings.
- Add a cross-talk API to the pin control GPIO back-end, utilizing
pinctrl_gpio_set_config() from GPIO drivers that want to set up a
certain pin configuration in the back-end.
This also includes the .set_config() refactoring of the GPIO chips,
so that they pass a generic configuration for things like
debouncing and single ended (typically open drain). This change has
also been merged in an immutable branch to the GPIO tree.
- Take hogs with a delayed work, so that we finalize probing a pin
controller before trying to get any hogs.
- For pin controllers putting all group and function definitions into
the device tree, we now have generic code to deal with this and it
is used in two drivers so far.
- Simplifications of the pin request conflict check.
- Make dt_free_map() optional.
Updates to drivers:
- pinctrl-single now use the generic helpers to generate dynamic
group and function tables from the device tree.
- Texas Instruments IOdelay configuration driver add-on to
pinctrl-single.
- i.MX: use radix trees to store groups and functions, use the new
generic group and function helpers to manage them.
- Intel: add support for hardware debouncing and 1K pull-down. New
subdriver for the Gemini Lake SoC.
- Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
- Aspeed: use syscon cross-dependencies to set up related bits in the
LPC host controller and display controller.
- Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
Add banks Y, Z, AA, AB and AC.
- AMD: support additional GPIO.
- STM32: set this controller to strict muxing mode. STM32H743 MCU
support.
- Allwinner sunxi: deep simplifications on how to support subvariants
of SoCs without adding to much SoC-specific data for each
subvariant, especially for sun5i variants. New driver for V3s SoCs.
New driver for the H5 SoC. Support A31/A31s variants with the new
variant framework.
- Mvebu: simplifications to use a MMIO and regmap abstraction. New
subdrivers for the 98DX3236, 98DX5241 SoCs.
- Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC
driver to access regmaps. Add infrastructure for pin-bank retention
control. Clean out the pin retention control from
arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in
the Samsung pin control driver(s).

HID: rmi: fallback to generic/multitouch if hid-rmi is not built
Commit
279967a65b32 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi")
unconditionally switches over handling of all Synaptics touchpads to hid-rmi
(to make use of extended features of the HW); in case CONFIG_HID_RMI is
disabled though this renders the touchpad unusable, as the
HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID)
match doesn't exist and generic/multitouch doesn't bind to it either (due
to hid group mismatch).
Fix this by switching over to hid-rmi only if it has been actually built.

Revert "ath10k: Search SMBIOS for OEM board file extension"
This reverts commit
f2593cb1b29185d38db706cbcbe22ed538720ae1.
Paul reported that this patch with older board-2.bin ath10k initialisation
fails on Dell XPS 13:
ath10k_pci 0000:3a:00.0: failed to fetch board data for bus=pci,vendor=168c,
device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520 from
ath10k/QCA6174/hw3.0/board-2.bin
The reason is that the older board-2.bin does not have the variant version of
the image name and ath10k does not fallback to the older naming scheme.

module: fix memory leak on early load_module() failures
While looking for early possible module loading failures I was

Currently, there's no good way to test for the presence of
set_memory_ro/rw/x/nx() helpers implemented by archs such as
x86, arm, arm64 and s390.
There's DEBUG_SET_MODULE_RONX and DEBUG_RODATA, however both
don't really reflect that: set_memory_*() are also available
even when DEBUG_SET_MODULE_RONX is turned off, and DEBUG_RODATA
is set by parisc, but doesn't implement above functions. Thus,
add ARCH_HAS_SET_MEMORY that is selected by mentioned archs,
where generic code can test against this.
This also allows later on to move DEBUG_SET_MODULE_RONX out of

====================
net: mvpp2: misc improvements and preparation patches
This series contains a number of fixes, misc improvements and
preparation patches for an upcoming series that adds support for the
new PPv2.2 network controller to the mvpp2 driver.
The most significant improvements are:
- Switching to using build_skb(), which is necessary for the upcoming
PPv2.2 support, but anyway a good improvement to the current mvpp2
driver (supporting PPv2.1).
- Making the driver build on 64-bit platforms.
Changes since v3:
- Addition of a patch "net: mvpp2: fix DMA address calculation in
mvpp2_txq_inc_put()", which fixes a bug in the driver in the
calculation of DMA addresses. This bug was found using
DMA_API_DEBUG.
- Modify the "net: mvpp2: switch to build_skb() in the RX path" patch
to recalculate the fragment size when the MTU is changed in
mvpp2_bm_update_mtu().
- Added Acked-by from Russell King on all patches, except:
* "net: mvpp2: fix DMA address calculation in
mvpp2_txq_inc_put()", because it's a new patch
* "net: mvpp2: switch to build_skb() in the RX path" because I
modified it since the v3.
- Rebased on top of 4.10.
Changes since v2:
- Fix remaining 64-bit build warning, reported by David Miller.
- Adjust how bit mask related definitions are done in "net: mvpp2:
simplify MVPP2_PRS_RI_* definitions" according to Russell King
suggestions.
- Add a patch "net: mvpp2: remove useless arguments in
mvpp2_rx_{pkts,time}_coal_set", suggested by Russell King.
- Rework mvpp2_rx_time_coal_set() implementation to avoid overflows
and rounding errors. I've used the implementation suggested by
Russell King.
Changes since v1:
- This series is split as a separate series from the larger patch set
adding support for PPv2.2 in the mvpp2 driver, as requested by
David Miller.
- Rebased on top of v4.10-rc1.

net: mvpp2: enable building on 64-bit platforms
The mvpp2 is going to be extended to support the Marvell Armada 7K/8K
platform, which is ARM64. As a preparation to this work, this commit
enables building the mvpp2 driver on ARM64, by:
- Adjusting the Kconfig dependency
- Fixing the types used in the driver so that they are 32/64-bits
compliant. We use dma_addr_t for DMA addresses, and unsigned long
for virtual addresses.
It is worth mentioning that after this commit, the driver is for now
still only used on 32-bits platforms, and will only work on 32-bits
platforms.

net: mvpp2: switch to build_skb() in the RX path
This commit adapts the mvpp2 RX path to use the build_skb() method. Not
only build_skb() is now the recommended mechanism, but it also
simplifies the addition of support for the PPv2.2 variant.
Indeed, without build_skb(), we have to keep track for each RX
descriptor of the physical address of the packet buffer, and the virtual
address of the SKB. However, in PPv2.2 running on 64 bits platform,
there is not enough space in the descriptor to store the virtual address
of the SKB. So having to take care only of the address of the packet
buffer, and building the SKB upon reception helps in supporting PPv2.2.
The implementation is fairly straightforward:
- mvpp2_skb_alloc() is renamed to mvpp2_buf_alloc() and no longer
allocates a SKB. Instead, it allocates a buffer using the new
mvpp2_frag_alloc() function, with enough space for the data and SKB.
- The initialization of the RX buffers in mvpp2_bm_bufs_add() as well
as the refill of the RX buffers in mvpp2_rx_refill() is adjusted
accordingly.
- Finally, the mvpp2_rx() is modified to use build_skb().

net: mvpp2: simplify MVPP2_PRS_RI_* definitions
Some of the MVPP2_PRS_RI_* definitions use the ~(value) syntax, which
doesn't compile nicely on 64-bit. Moreover, those definitions are in
fact unneeded, since they are always used in combination with a bit
mask that ensures only the appropriate bits are modified.
Therefore, such definitions should just be set to 0x0. In addition, as
suggested by Russell King, we change the _MASK definitions to also use
the BIT() macro so that it is clear they are related to the values
defined afterwards.
For example:
#define MVPP2_PRS_RI_L2_CAST_MASK 0x600
#define MVPP2_PRS_RI_L2_UCAST ~(BIT(9) | BIT(10))
#define MVPP2_PRS_RI_L2_MCAST BIT(9)
#define MVPP2_PRS_RI_L2_BCAST BIT(10)
becomes
#define MVPP2_PRS_RI_L2_CAST_MASK (BIT(9) | BIT(10))
#define MVPP2_PRS_RI_L2_UCAST 0x0
#define MVPP2_PRS_RI_L2_MCAST BIT(9)
#define MVPP2_PRS_RI_L2_BCAST BIT(10)
Because the values (MVPP2_PRS_RI_L2_UCAST, MVPP2_PRS_RI_L2_MCAST and
MVPP2_PRS_RI_L2_BCAST) are always applied with
MVPP2_PRS_RI_L2_CAST_MASK, and therefore there is no need for
MVPP2_PRS_RI_L2_UCAST to be defined as ~(BIT(9) | BIT(10)).
It fixes the following warnings when building the driver on a 64-bit
platform (which is not possible as of this commit, but will be enabled
in a follow-up commit):

net: mvpp2: release reference to txq_cpu[] entry after unmapping
The mvpp2_txq_bufs_free() function is called upon TX completion to DMA
unmap TX buffers, and free the corresponding SKBs. It gets the
references to the SKB to free and the DMA buffer to unmap from a per-CPU
txq_pcpu data structure.
However, the code currently increments the pointer to the next entry
before doing the DMA unmap and freeing the SKB. It does not cause any
visible problem because for a given SKB the TX completion is guaranteed
to take place on the CPU where the TX was started. However, it is much
more logical to increment the pointer to the next entry once the current
entry has been completely unmapped/released.

When TX descriptors are filled in, the buffer DMA address is split
between the tx_desc->buf_phys_addr field (high-order bits) and
tx_desc->packet_offset field (5 low-order bits).
However, when we re-calculate the DMA address from the TX descriptor in
mvpp2_txq_inc_put(), we do not take tx_desc->packet_offset into
account. This means that when the DMA address is not aligned on a 32
bytes boundary, we end up calling dma_unmap_single() with a DMA address
that was not the one returned by dma_map_single().
This inconsistency is detected by the kernel when DMA_API_DEBUG is

problematic, to reference counting using krefs.
