While the current code was reporting to be able to work in master mode, it
failed to do so because the BCLK divider wasn't programmed, meaning that
the BCLK would run at the PLL's frequency no matter the sample rate.
It was obviously a bit too fast.
Add support to retrieve the divider to use, and set it. Since our PLL is
not always able to generate a perfect multiple of the sample rate, we'll
have to choose the closest divider that matches our setup.

Current codec drivers are using snd_soc_read(). It will be replaced
into snd_soc_component_read(), but these 2 are using different style.
For example, it will be
- val = snd_soc_read(xxx, reg);
+ ret = snd_soc_component_read(xxx, reg, &val);
+ if (ret < 0) {
+ ...
+ }
To more smooth replace, let's add snd_soc_component_read32
which is copied from snd_soc_read()
- val = snd_soc_read(xxx, reg);
+ val = snd_soc_component_read32(xxx, reg);

There have been some cases where external tooling (e.g., kpatch-build)
creates a corrupt relocation which targets the wrong address. This is a
silent failure which can corrupt memory in unexpected places.
On x86, the bytes of data being overwritten by relocations are always
initialized to zero beforehand. Use that knowledge to add sanity checks
to detect such cases before they corrupt memory.

This fixes the following warning with GCC 4.6:
mm/migrate.o: warning: objtool: migrate_misplaced_transhuge_page()+0x71: unreachable instruction
The problem is that the compiler merged identical annotate_unreachable()
inline asm blocks, resulting in a missing 'unreachable' annotation.
This problem happened before, and was partially fixed with:
3d1e236022 ("objtool: Prevent GCC from merging annotate_unreachable()")
That commit tried to ensure that each instance of the
annotate_unreachable() inline asm statement has a unique label. It used
the __LINE__ macro to generate the label number. However, even the line
number isn't necessarily unique when used in an inline function with
multiple callers (in this case, __alloc_pages_node()'s use of
VM_BUG_ON).

This reverts commit 43858b4f25.
The reason I removed the leave_mm() calls in question is because the
heuristic wasn't needed after that patch. With the original version
of my PCID series, we never flushed a "lazy cpu" (i.e. a CPU running
kernel thread) due a flush on the loaded mm.
Unfortunately, that caused architectural issues, so now I've
reinstated these flushes on non-PCID systems in:
commit b956575bed ("x86/mm: Flush more aggressively in lazy TLB mode").
That, in turn, gives us a power management and occasionally
performance regression as compared to old kernels: a process that
goes into a deep idle state on a given CPU and gets its mm flushed
due to activity on a different CPU will wake the idle CPU.
Reinstate the old ugly heuristic: if a CPU goes into ACPI C3 or an
intel_idle state that is likely to cause a TLB flush gets its mm
switched to init_mm before going idle.
FWIW, this heuristic is lousy. Whether we should change CR3 before
idle isn't a good hint except insofar as the performance hit is a bit
lower if the TLB is getting flushed by the idle code anyway. What we
really want to know is whether we anticipate being idle long enough
that the mm is likely to be flushed before we wake up. This is more a
matter of the expected latency than the idle state that gets chosen.
This heuristic also completely fails on systems that don't know
whether the TLB will be flushed (e.g. AMD systems?). OTOH it may be a
bit obsolete anyway -- PCID systems don't presently benefit from this
heuristic at all.
We also shouldn't do this callback from innermost bit of the idle code
due to the RCU nastiness it causes. All the information need is
available before rcu_idle_enter() needs to happen.

After the SPDX license tags were added a number of tooling headers got out of
sync with their kernel variants, generating lots of build warnings.
Sync them:
- tools/arch/x86/include/asm/disabled-features.h,
tools/arch/x86/include/asm/required-features.h,
tools/include/linux/hash.h:
Remove the SPDX tag where the kernel version does not have it.
- tools/include/asm-generic/bitops/__fls.h,
tools/include/asm-generic/bitops/arch_hweight.h,
tools/include/asm-generic/bitops/const_hweight.h,
tools/include/asm-generic/bitops/fls.h,

tools/include/uapi/linux/perf_event.h,
tools/include/uapi/linux/sched.h,
tools/include/uapi/linux/vhost.h,
tools/include/uapi/sound/asound.h:
Add the SPDX tag of the respective kernel header.
- tools/include/uapi/linux/bpf_common.h,
tools/include/uapi/linux/fcntl.h,
tools/include/uapi/linux/hw_breakpoint.h,
tools/include/uapi/linux/mman.h,
tools/include/uapi/linux/stat.h,
Change the tag to the kernel header version:
-/* SPDX-License-Identifier: GPL-2.0 */
+/* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note */
Also sync other header details:
- include/uapi/sound/asound.h:
Fix pointless end of line whitespace noise the header grew in this cycle.
- tools/arch/x86/lib/memcpy_64.S:
Sync the code and add tools/include/asm/export.h with dummy wrappers
to support building the kernel side code in a tooling header environment.
- tools/include/uapi/asm-generic/mman.h,
tools/include/uapi/linux/bpf.h:
Sync other details that don't impact tooling's use of the ABIs.

Sync events are sent by sparse_keymap_report_entry for normal KEY_*
events, and are generated by several drivers after generating
SW_* events, so sparse_keymap_report_entry should do the same.
Without the sync, events are accumulated in the kernel.
Currently, no driver uses sparse-keymap for SW_* events, but
it is required for the intel-vbtn platform driver to generate
SW_TABLET_MODE events.

A fix to the handling of misaligned paste instructions (P9 only), where a change
to a #define has caused the check for the instruction to always fail.
The preempt handling was unbalanced in the radix THP flush (P9 only). Though we
don't generally use preempt we want to keep it working as much as possible.
Two fixes for IMC (P9 only), one when booting with restricted number of CPUs and
one in the error handling when initialisation fails due to firmware etc.
A revert to fix function_graph on big endian machines, and then a rework of the
reverted patch to fix kprobes blacklist handling on big endian machines.

MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:
- Have 10 or more patches in mainline authored using an @imgtec.com
email address, or any patches dated within the past year.
- Are still with Imagination but leaving as part of the MIPS business
unit, as determined from an internal email address list.
- Haven't already updated their email address (ie. JamesH) or expressed
a desire to be excluded (ie. Maciej).
- Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
myself.
New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list. An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.
Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.

Commit 890da9cf09 (Revert "x86: do not use cpufreq_quick_get() for
/proc/cpuinfo "cpu MHz"") is not sufficient to restore the previous
behavior of "cpu MHz" in /proc/cpuinfo on x86 due to some changes
made after the commit it has reverted.
To address this, make the code in question use arch_freq_get_on_cpu()
which also is used by cpufreq for reporting the current frequency of
CPUs and since that function doesn't really depend on cpufreq in any
way, drop the CONFIG_CPU_FREQ dependency for the object file
containing it.
Also refactor arch_freq_get_on_cpu() somewhat to avoid IPIs and
return cached values right away if it is called very often over a
short time (to prevent user space from triggering IPI storms through
it).
