Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid
Pull HID updates from Jiri Kosina: - support for U2F Zero device, from Andrej Shadura - logitech-dj has historically been treating devices behind non-unifying receivers as generic devices, using the HID emulation in the receiver. That had several shortcomings (special keys handling, battery level monitoring, etc). The driver has been reworked to enumarate (and directly communicate with) the devices behind the receiver, to avoid the (too) generic HID implementation in the receiver itself. All the work done by Benjamin Tissoires and Hans de Goede. - restructuring of intel-ish driver in order to allow for multiple clients of the ISH implementation, from Srinivas Pandruvada - several other smaller fixes and assorted device ID additions * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid: (68 commits) HID: logitech-dj: fix spelling in printk HID: input: fix assignment of .value HID: input: make sure the wheel high resolution multiplier is set HID: logitech-dj: add usbhid dependency in Kconfig HID: logitech-hidpp: add support for HID++ 1.0 consumer keys reports HID: logitech-hidpp: add support for HID++ 1.0 extra mouse buttons reports HID: logitech-hidpp: add support for HID++ 1.0 wheel reports HID: logitech-hidpp: make hidpp10_set_register_bit a bit more generic HID: logitech-hidpp: add input_device ptr to struct hidpp_device HID: logitech-hidpp: do not hardcode very long report length HID: logitech-hidpp: handle devices attached to 27MHz wireless receivers HID: logitech-hidpp: use RAP instead of FAP to get the protocol version HID: logitech-hidpp: remove unused origin_is_hid_core function parameter HID: logitech-hidpp: remove double assignment from __hidpp_send_report HID: logitech-hidpp: do not make failure to get the name fatal HID: logitech-hidpp: ignore very-short or empty names HID: logitech-hidpp: make .probe usbhid capable HID: logitech-hidpp: allow non HID++ devices to be handled by this module HID: logitech-dj: add support for Logitech Bluetooth Mini-Receiver HID: logitech-dj: make appending of the HID++ descriptors conditional ... |

spi: Updates for v5.2
One small feature was added this release but the bulk of the diffstat
and the changelog comes from the fact that several older drivers got
some fairly hefty reworks and a couple of new drivers were added:
- Support for detailed control of timing around chip selects from
Sowjanya Komatineni.
- A big set of fixes and imrovements for the Tegra114 driver from
Sowjanya Komatineni.
- A big simplification of the GPIO driver from Andrey Smirnov.
- DMA support and fixes for the Freescale LPSPI driver from Clark Wang.
- Fixes and optimizations for the bcm2835aux from Martin Sparl.
- New drivers for Mediatek MT7621 (graduated from staging) and Zynq QSPI.

regulator: Updates for v5.2
In terms of big picture changes this has been an extremely quiet release
however there's a lot of changes and a fairly big diffstat thanks to a
bunch of small fixes, mainly coming from Axel Lin. Thanks to his work
this release removes code overall even though we've added a new (albiet
fairly small) driver.
Notable things:
- A fix for a long standing issue with locking on error interrupts from
Steve Twiss.
- A new driver for ST Microelectonics STM32 PWR.

module loading, trampoline handling and other bits.

structured.
- remove DISCONTIGMEM support on x86-32 and make SPARSEMEM the
default.

"The changes in this cycle were:
- Remove the irq timings/variance statistics code that tried to

which is superior to the previous one as it can detect not just a
single periodic pattern, but independent periodic patterns along a
log-2 scale of bucketing and exponential moving average. The
comments are longer than the code - and it works better at
predicting various complex interrupt patterns from real-world
devices than the previous estimate.

Merge branch 'core-stacktrace-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull stack trace updates from Ingo Molnar:
"So Thomas looked at the stacktrace code recently and noticed a few
weirdnesses, and we all know how such stories of crummy kernel code
meeting German engineering perfection end: a 45-patch series to clean
it all up! :-)
Here's the changes in Thomas's words:
'Struct stack_trace is a sinkhole for input and output parameters
which is largely pointless for most usage sites. In fact if embedded
into other data structures it creates indirections and extra storage
overhead for no benefit.
Looking at all usage sites makes it clear that they just require an
interface which is based on a storage array. That array is either on
stack, global or embedded into some other data structure.
Some of the stack depot usage sites are outright wrong, but
fortunately the wrongness just causes more stack being used for
nothing and does not have functional impact.
Another oddity is the inconsistent termination of the stack trace
with ULONG_MAX. It's pointless as the number of entries is what
determines the length of the stored trace. In fact quite some call
sites remove the ULONG_MAX marker afterwards with or without nasty
comments about it. Not all architectures do that and those which do,
do it inconsistenly either conditional on nr_entries == 0 or
unconditionally.
The following series cleans that up by:
1) Removing the ULONG_MAX termination in the architecture code
2) Removing the ULONG_MAX fixups at the call sites
3) Providing plain storage array based interfaces for stacktrace
and stackdepot.
4) Cleaning up the mess at the callsites including some related
cleanups.
5) Removing the struct stack_trace based interfaces
This is not changing the struct stack_trace interfaces at the
architecture level, but it removes the exposure to the generic
code'"

Merge branch 'core-objtool-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull objtool updates from Ingo Molnar:
"This is a series from Peter Zijlstra that adds x86 build-time uaccess
validation of SMAP to objtool, which will detect and warn about the
following uaccess API usage bugs and weirdnesses:
- call to %s() with UACCESS enabled
- return with UACCESS enabled
- return with UACCESS disabled from a UACCESS-safe function
- recursive UACCESS enable
- redundant UACCESS disable
- UACCESS-safe disables UACCESS
As it turns out not leaking uaccess permissions outside the intended
uaccess functionality is hard when the interfaces are complex and when
such bugs are mostly dormant.
As a bonus we now also check the DF flag. We had at least one
high-profile bug in that area in the early days of Linux, and the
checking is fairly simple. The checks performed and warnings emitted
are:
- call to %s() with DF set
- return with DF set
- return with modified stack frame
- recursive STD
- redundant CLD
It's all x86-only for now, but later on this can also be used for PAN
on ARM and objtool is fairly cross-platform in principle.
While all warnings emitted by this new checking facility that got
reported to us were fixed, there might be GCC version dependent
warnings that were not reported yet - which we'll address, should they
trigger.
The warnings are non-fatal build warnings"

ubsan: Fix nasty -Wbuiltin-declaration-mismatch GCC-9 warnings
Building lib/ubsan.c with gcc-9 results in a ton of nasty warnings like
this one:
lib/ubsan.c warning: conflicting types for built-in function
‘__ubsan_handle_negate_overflow’; expected ‘void(void *, void *)’ [-Wbuiltin-declaration-mismatch]
The kernel's declarations of __ubsan_handle_*() often uses 'unsigned
long' types in parameters while GCC these parameters as 'void *' types,
hence the mismatch.
Fix this by using 'void *' to match GCC's declarations.
