WQ_HIGHPRI increases throughput and decreases disk latency when using

The following tests were run by doing 60 seconds of random reads using
a dm-verity device backed by two ramdisks.
Without WQ_HIGHPRI

AMD systems support zero CBM (capacity bit mask) for cache allocation.
That is reflected in rdt_init_res_defs_amd() by:
r->cache.arch_has_empty_bitmaps = true;
However given the unified code in cbm_validate(), checking for:
val == 0 && !arch_has_empty_bitmaps
is not enough because of another check in cbm_validate():
if ((zero_bit - first_bit) < r->cache.min_cbm_bits)
The default value of r->cache.min_cbm_bits = 1.
Leading to:
$ cd /sys/fs/resctrl
$ mkdir foo
$ cd foo
$ echo L3:0=0 > schemata
-bash: echo: write error: Invalid argument
$ cat /sys/fs/resctrl/info/last_cmd_status
Need at least 1 bits in the mask
Initialize the min_cbm_bits to 0 for AMD. Also, remove the default
setting of min_cbm_bits and initialize it separately.
After the fix:
$ cd /sys/fs/resctrl
$ mkdir foo
$ cd foo
$ echo L3:0=0 > schemata
$ cat /sys/fs/resctrl/info/last_cmd_status
ok

The function test_bit doesn't provide any memory barrier. It may be
possible that the read requests that follow test_bit(B_READING, &b->state)
are reordered before the test, reading invalid data that existed before
B_READING was cleared.
Fix this bug by changing test_bit to test_bit_acquire. This is
particularly important on arches with weak(er) memory ordering
(e.g. arm64).

Address this by partially reverting commit 4919d3eb2e so that
cmos_wake_setup() is called before cmos_do_probe() again and moving
the rtc_wake_setup() invocation from cmos_wake_setup() directly to the
callers of cmos_do_probe() where it will happen after a successful

NMI interrupts should exit with EXCEPTION_RESTORE_REGS not with
interrupt_return_srr, which is what the perf NMI handler currently does.
This breaks if a PMI hits after interrupt_exit_user_prepare_main() has
switched the context tracking to user mode, then the CT_WARN_ON() in
interrupt_exit_kernel_prepare() fires because it returns to kernel with
context set to user.
This could possibly be solved by soft-disabling PMIs in the exit path,
but that reduces our ability to profile that code. The warning could be
removed, but it's potentially useful.
All other NMIs and soft-NMIs return using EXCEPTION_RESTORE_REGS, so
this makes perf interrupts consistent with that and seems like the best
fix.
