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);

I ran into a build error with CONFIG_SND_SOC_INTEL_COMMON=m
and SND_SOC_INTEL_MACH=y:
ERROR: "snd_soc_acpi_intel_broadwell_machines" [sound/soc/intel/common/snd-soc-sst-acpi.ko] undefined!

ERROR: "snd_soc_acpi_intel_baytrail_machines" [sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined!
The problem here is that the sound/soc/intel/common/ directory
is then entered only for building modules, but the sst-acpi.o
never gets built since it depends on a built-in Kconfig symbol.
That configuration obviously makes no sense since all options
below SND_SOC_INTEL_MACH also depend on something else that
in turn depends on CONFIG_SND_SOC_INTEL_COMMON.
Adding a SND_SOC_INTEL_SST_TOPLEVEL dependency to SND_SOC_INTEL_MACH
solves the build error. I notice we can also consolidate the
'depends on SND_SOC_INTEL_MACH' lines by using an 'if' block to
simplify it further and make sure the configuration stays sane.

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/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,

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.
