Resolved context clashes with other commits and v3 updates to patches 0003, 0004
v2: fix errors flagged by checkpatch
New Functions
smu_bump_power_profile_mode() - changes profile mode assuming calling function already has mutex

smu_print_ppclk_levels() - accepts Powerplay enum pp_clock_type to request clock levels
amdgpu_get_pp_dpm_clock() - accepts Powerplay enum pp_clock_type to request clock levels and allows
all the amdgpu_get_pp_dpm_$CLK functions to have a single codepath
amdgpu_set_pp_dpm_clock() - accepts Powerplay enum pp_clock_type to set clock levels and allows
all the amdgpu_set_pp_dpm_$CLK functions to have a single codepath
Modified Functions
smu_force_smuclk_levels - changed function name to make clear difference to smu_force_ppclk_levels
smu_force_ppclk_levels() - modifed signature to implement Powerplay API force_clock_level

- removed arg lock_needed, mutex always locked, internal functions
can call smu_bump if they already hold lock
smu_switch_power_profile - now calls smu_bump as already holds mutex lock
smu_adjust_power_state_dynamic - now calls smu_bump as already holds mutex lock
amdgpu_get_pp_od_clk_voltage - uses smu_print_ppclk_levels
amdgpu_{set,get}_pp_dpm_$CLK - replace logic with call helper function amdgpu_{set,get}_pp_dpm_clock()
CLK ={sclk, mclk, socclk, fclk, dcefclk, pci, vclkd, dclk}

There exists multiple path may do zram compaction concurrently.
1. auto-compaction triggered during memory reclaim
2. userspace utils write zram<id>/compaction node
So, multiple threads may call zs_shrinker_scan/zs_compact concurrently.
But pages_compacted is a per zsmalloc pool variable and modification
of the variable is not serialized(through under class->lock).
There are two issues here:
1. the pages_compacted may not equal to total number of pages
freed(due to concurrently add).
2. zs_shrinker_scan may not return the correct number of pages
freed(issued by current shrinker).
The fix is simple:
1. account the number of pages freed in zs_compact locally.
2. use actomic variable pages_compacted to accumulate total number.

Right now, we only check against MAX_PHYSMEM_BITS - but turns out there
are more restrictions of which memory we can actually hotplug, especially
om arm64 or s390x once we support them: we might receive something like
-E2BIG or -ERANGE from add_memory_driver_managed(), stopping device
operation.
So, check right when initializing the device which memory we can add,
warning the user. Try only adding actually pluggable ranges: in the worst
case, no memory provided by our device is pluggable.
In the usual case, we expect all device memory to be pluggable, and in
corner cases only some memory at the end of the device-managed memory
region to not be pluggable.

No need to store the value for each and every memory block, as we can
easily query the value at runtime. Reshuffle the members to optimize the
memory layout. Also, let's clarify what the interface once was used for
and why it's legacy nowadays.
"phys_device" was used on s390x in older versions of lsmem[2]/chmem[3],
back when they were still part of s390x-tools. They were later replaced
by the variants in linux-utils. For example, RHEL6 and RHEL7 contain
lsmem/chmem from s390-utils. RHEL8 switched to versions from util-linux
on s390x [4].
"phys_device" was added with sysfs support for memory hotplug in commit
3947be1969a9 ("[PATCH] memory hotplug: sysfs and add/remove functions") in
2005. It always returned 0.
s390x started returning something != 0 on some setups (if sclp.rzm is set
by HW) in 2010 via commit 57b552ba0b2f ("memory hotplug/s390: set
phys_device").
For s390x, it allowed for identifying which memory block devices belong to
the same storage increment (RZM). Only if all memory block devices
comprising a single storage increment were offline, the memory could
actually be removed in the hypervisor.
Since commit e5d709bb5fb7 ("s390/memory hotplug: provide
memory_block_size_bytes() function") in 2013 a memory block device spans
at least one storage increment - which is why the interface isn't really
helpful/used anymore (except by old lsmem/chmem tools).
There were once RFC patches to make use of "phys_device" in ACPI context;
however, the underlying problem could be solved using different interfaces

Some of them have gaps, or fields we don't clear. Native ioctl code
does full copies plus zero-extends on size mismatch, so nothing can
leak. But compat is more hand-rolled so need to be careful.
None of these matter for performance, so just memset.
Also I didn't fix up the CONFIG_DRM_LEGACY or CONFIG_DRM_AGP ioctl, those
are security holes anyway.

Commit b102f0c522cf6 ("mt76: fix array overflow on receiving too many
fragments for a packet") fixes a possible OOB access but it introduces a
memory leak since the pending frame is not released to page_frag_cache
if the frag array of skb_shared_info is full. Commit 93a1d4791c10
("mt76: dma: fix a possible memory leak in mt76_add_fragment()") fixes
the issue but does not free the truncated skb that is forwarded to
mac80211 layer. Fix the leftover issue discarding even truncated skbs.
