Offlining a CPU and bringing it back online is a common operation and it
happens frequently during system suspend/resume, where the non-boot CPUs
are hotplugged out during suspend and brought back at resume.
The cpufreq core already tries to make this path as fast as possible as
the changes are only temporary in nature and full cleanup of resources
isn't required in this case. For example the drivers can implement
online()/offline() callbacks to avoid a lot of tear down of resources.
On similar lines, there is no need to unregister the cpufreq cooling
device during suspend / resume, but only while the policy is getting
removed.
Moreover, unregistering the cpufreq cooling device is resulting in an
unwanted outcome, where the system suspend is eventually aborted in the
process. Currently, during system suspend the cpufreq core unregisters
the cooling device, which in turn removes a kobject using device_del()
and that generates a notification to the userspace via uevent broadcast.
This causes system suspend to abort in some setups.
This was also earlier reported (indirectly) by Roman [1]. Maybe there is
another way around to fixing that problem properly, but this change
makes sense anyways.
Move the registering and unregistering of the cooling device to policy
creation and removal times onlyy.

The x86 architecture has an idle routine for AMD CPUs which are affected
by erratum 400. On the affected CPUs the local APIC timer stops in the
C1E halt state.
It therefore requires tick broadcasting. The invocation of
tick_broadcast_enter()/exit() from this function violates the RCU
constraints because it can end up in lockdep or tracing, which
rightfully triggers a warning.
tick_broadcast_enter()/exit() must be invoked before ct_cpuidle_enter()
and after ct_cpuidle_exit() in default_idle_call().
Add a static branch conditional invocation of tick_broadcast_enter()/exit()
into this function to allow X86 to replace the AMD specific idle code. It's
guarded by a config switch which will be selected by x86. Otherwise it's
a NOOP.

SETUP_RNG_SEED in setup_data is supplied by kexec and should
not be reserved in the e820 map.
Doing so reserves 16 bytes of RAM when booting with kexec.
(16 bytes because data->len is zeroed by parse_setup_data so only
sizeof(setup_data) is reserved.)
When kexec is used repeatedly, each boot adds two entries in the
kexec-provided e820 map as the 16-byte range splits a larger
range of usable memory. Eventually all of the 128 available entries
get used up. The next split will result in losing usable memory
as the new entries cannot be added to the e820 map.

ice_qp_dis() currently does things in very mixed way. Tx is stopped
before disabling IRQ on related queue vector, then it takes care of
disabling Rx and finally NAPI is disabled.
Let us start with disabling IRQs in the first place followed by turning
off NAPI. Then it is safe to handle queues.
One subtle change on top of that is that even though ice_qp_ena() looks
more sane, clear ICE_CFG_BUSY as the last thing there.

Currently routines that are supposed to toggle state of ring pair do not
take care of associated interrupt with queue vector that these rings
belong to. This causes funky issues such as dead interface due to irq
misconfiguration, as per Pavel's report from Closes: tag.
Add a function responsible for disabling single IRQ in EIMC register and
call this as a very first thing when disabling ring pair during xsk_pool
setup. For enable let's reuse ixgbe_irq_enable_queues(). Besides this,
disable/enable NAPI as first/last thing when dealing with closing or
opening ring pair that xsk_pool is being configured on.

pktcdvd sets max_hw_sectors on the queue of the underlying device that
it doesn't own (and doesn't reset it ever) since the driver was merged.
This can create all kinds of problems as the underlying driver doesn't
even know about it changing the limit.
As the state purpose is to not create I/Os larger than a single frame,
and pktcdvd never builds bios larger than that, just set REQ_NOMERGE
on the bios it submits so that largers I/Os never get built.
Note: I don't have packet writing hardware, so this is compile tested
only.

It is helpful to see the saved record entries during run time in
human-readable format. This is useful for testing during module
development. It can also be used by system admins to quickly and easily
see the state of the system.
Provide a sequential file in debugfs to print fields of interest from
the FRU records and their entries.
Don't fail to load the module if the debugfs interface is not available.
This is a convenience feature which does not affect other module
functionality.
The new interface reads the record entries and should hold the mutex.
Expand the mutex code comment to clarify when it should be held.

The system physical address (SPA) of an error is not a stable value. It
will change depending on the location of the memory: parts can be
swapped. And it will change depending on memory topology: NUMA nodes
and/or interleaving can be adjusted.
Therefore, the SPA value is not part of the "FRU Memory Poison" record
format. And it will not be saved to persistent storage.
However, the SPA values can be helpful during debug and for system
admins during run time.
Save the SPA values in a separate structure. This is updated when
records are restored and when new errors are saved.

comments. ]

For earlier kmem cache creation, slab_sysfs_init() has not been called.
Consequently, kmem_cache_destroy() cannot utilize kobj_type::release to
release the kmem_cache structure. Therefore, tweak kmem_cache_release()
to use slab_kmem_cache_release() for releasing kmem_cache when slab_state
isn't FULL. This will fixes the memory leaks like following:

Limit the WiFi PCIe link speed to Gen2 speed (500 MB/s), which is the
speed that the boot firmware has brought up the link at (and that
Windows uses).
This is specifically needed to avoid a large amount of link errors when
restarting the link during boot (but which are currently not reported).
This also appears to fix intermittent failures to download the ath11k
firmware during boot which can be seen when there is a longer delay
between restarting the link and loading the WiFi driver (e.g. when using
full disk encryption).
