intel-gpio for v5.20-1

* Clean up the GPIO driver of Intel EG20 PCH

The following is an automated git shortlog grouped by driver:

pch:
 -  Change PCI device macros
 -  Use dev_err_probe()

669f5618fe gpio: adp5588: Do not use defined value for driver name and compatible
It's wrong to use defined string literal for three semantically different
cases, i.e.:
1) compatible string, which is part of ABI and has to have specific format;
2) I2C ID, which is user space visible and also ABI;
3) driver name, that can be changed.

Drop the define and use appropriate string literals in place.

While at it, drop comma at terminator entry of OF ID table.

3d57fa2a22 gpio: xgs-iproc: Drop if with an always false condition
The remove callback is only called after probe completed successfully.
In this case platform_set_drvdata() was called with a non-NULL argument
and so chip is never NULL.

Also note that returning an error code from a remove callback doesn't
result in the device staying bound. It's still removed and devm
callbacks are called.

This is a preparation for making platform remove callbacks return void.

421e3c16c3 gpio: twl4030: Don't return an error after WARN in .remove
Returning a non-zero value in a platform driver's remove callback only
results in an error message ("remove callback returned a non-zero value.
This will be ignored.", see platform_remove()), and then the device is
removed anyhow.

As there was just a WARN_ON triggered, return 0 to drop the follow up
warning. The latter output is hardly relevant after the big WARN splat.

ced7866db3 drm/i915/ttm: fix 32b build
Since segment_pages is no longer a compile time constant, it looks the
DIV_ROUND_UP(node->size, segment_pages) breaks the 32b build. Simplest
is just to use the ULL variant, but really we should need not need more
than u32 for the page alignment (also we are limited by that due to the
sg->length type), so also make it all u32.

4b335e1e0d perf trace: Fix SIGSEGV when processing syscall args
On powerpc, 'perf trace' is crashing with a SIGSEGV when trying to
process a perf.data file created with 'perf trace record -p':

  #0  0x00000001225b8988 in syscall_arg__scnprintf_augmented_string <snip> at builtin-trace.c:1492
  #1  syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1492

  #5  0x00000001225bff04 in trace__sys_enter <snip> at builtin-trace.c:2319

That points to the below code in tools/perf/builtin-trace.c:
	/*
	 * If this is raw_syscalls.sys_enter, then it always comes with the 6 possible
	 * arguments, even if the syscall being handled, say "openat", uses only 4 arguments
	 * this breaks syscall__augmented_args() check for augmented args, as we calculate
	 * syscall->args_size using each syscalls:sys_enter_NAME tracefs format file,
	 * so when handling, say the openat syscall, we end up getting 6 args for the
	 * raw_syscalls:sys_enter event, when we expected just 4, we end up mistakenly
	 * thinking that the extra 2 u64 args are the augmented filename, so just check
	 * here and avoid using augmented syscalls when the evsel is the raw_syscalls one.
	 */
	if (evsel != trace->syscalls.events.sys_enter)
		augmented_args = syscall__augmented_args(sc, sample, &augmented_args_size, trace->raw_augmented_syscalls_args_size);

As the comment points out, we should not be trying to augment the args
for raw_syscalls. However, when processing a perf.data file, we are not
initializing those properly. Fix the same.

eee51fe38e tools headers UAPI: Sync linux/kvm.h with the kernel sources
To pick the changes in:

  1b870fa557 ("kvm: stats: tell userspace which values are boolean")

That just rebuilds perf, as these patches don't add any new KVM ioctl to
be harvested for the the 'perf trace' ioctl syscall argument
beautifiers.

This is also by now used by tools/testing/selftests/kvm/, a simple test
build succeeded.

This silences this perf build warning:

Pull btrfs reverts from David Sterba:
 "Due to a recent report [1] we need to revert the radix tree to xarray
  conversion patches.

  There's a problem with sleeping under spinlock, when xa_insert could
  allocate memory under pressure. We use GFP_NOFS so this is a real
  problem that we unfortunately did not discover during review.

  I'm sorry to do such change at rc6 time but the revert is IMO the
  safer option, there are patches to use mutex instead of the spin locks
  but that would need more testing. The revert branch has been tested on
  a few setups, all seem ok.

  The conversion to xarray will be revisited in the future"

829d680e82 random: cap jitter samples per bit to factor of HZ
Currently the jitter mechanism will require two timer ticks per
iteration, and it requires N iterations per bit. This N is determined
with a small measurement, and if it's too big, it won't waste time with
jitter entropy because it'd take too long or not have sufficient entropy
anyway.

With the current max N of 32, there are large timeouts on systems with a
small CONFIG_HZ. Rather than set that maximum to 32, instead choose a
factor of CONFIG_HZ. In this case, 1/30 seems to yield sane values for
different configurations of CONFIG_HZ.
