Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.8 kernel cycle.
Core changes:
- A new GPIO aggregator driver has been merged: this can join a few
select GPIO lines into a new aggregated GPIO chip. This can be used
for security: a process can be granted access to only these lines,
for example for industrial control. Another way to use this is to
reexpose certain select lines to a virtual machine or container.
- Warn if the gpio-line-names is too long in he DT parser core.
- GPIO lines can now be looked up by line name in addition to being
looked up by offset.
New drivers:
- A new generic regmap GPIO driver has been merged. Too many regmap
drivers are starting to look like each other so we need to create
some common ground and try to move drivers over to using that.
- The F7188X driver now supports F81865.
Driver improvements:
- Large improvements to the PCA953x expander, get multiple lines and
several cleanups.
- Large improvements to the DesignWare DWAPB driver, and Sergey Semin
has volunteered to maintain it.
- PL061 can now be built as a module, this is part of a bigger effort
to make the ARM platforms more modular"

Test some bit clears/sets to make sure assembly doesn't change, and that
the set_bit and clear_bit functions work and don't cause sparse warnings.
Instruct Kbuild to build this file with extra warning level -Wextra, to
catch new issues, and also doesn't hurt to build with C=1.
This was used to test changes to arch/x86/include/asm/bitops.h.
In particular, sparse (C=1) was very concerned when the last bit before a
natural boundary, like 7, or 31, was being tested, as this causes sign
extension (0xffffff7f) for instance when clearing bit 7.
Recommended usage:
make defconfig
scripts/config -m CONFIG_TEST_BITOPS
make modules_prepare
make C=1 W=1 lib/test_bitops.ko
objdump -S -d lib/test_bitops.ko
insmod lib/test_bitops.ko
rmmod lib/test_bitops.ko
<check dmesg>, there should be no compiler/sparse warnings and no
error messages in log.

- promised cleanups after introducing exec_update_mutex
- trivial cleanups for exec

Pull proc updates from Eric Biederman:
"This has four sets of changes:
- modernize proc to support multiple private instances
- ensure we see the exit of each process tid exactly
- remove has_group_leader_pid
- use pids not tasks in posix-cpu-timers lookup
Alexey updated proc so each mount of proc uses a new superblock. This
allows people to actually use mount options with proc with no fear of
messing up another mount of proc. Given the kernel's internal mounts
of proc for things like uml this was a real problem, and resulted in
Android's hidepid mount options being ignored and introducing security
issues.
The rest of the changes are small cleanups and fixes that came out of
my work to allow this change to proc. In essence it is swapping the
pids in de_thread during exec which removes a special case the code
had to handle. Then updating the code to stop handling that special
case"
