Currently, vcpu_is_preempted will return the yield_count for
shared_processor. On a PowerVM LPAR, Phyp schedules at SMT8 core boundary
i.e all CPUs belonging to a core are either group scheduled in or group
scheduled out. This can be used to better predict non-preempted CPUs on
PowerVM shared LPARs

Introduce a static branch that would be set during boot if the OS
happens to be a KVM guest. Subsequent checks to see if we are on KVM
will rely on this static branch. This static branch would be used in
vcpu_is_preempted in a subsequent patch.

Yeah, one of the things I discussed
To reset mwifiex on Surface gen4+ (Pro 4 or later gen) devices, it
seems that putting the wifi device into D3cold is required according
to errata.inf file on Windows installation (Windows/INF/errata.inf).
This patch adds a function that performs power-cycle (put into D3cold

If its a shared lpar but not a KVM guest, then see if the vCPU is
related to the calling vCPU. On PowerVM, only cores can be preempted.
So if one vCPU is a non-preempted state, we can decipher that all other
vCPUs sharing the same core are in non-preempted state.

Dear RT folks!
I'm pleased to announce the v5.9.1-rt20 patch set.
Changes since v5.9.1-rt19:
- Tiny update to the rtmutex patches (make __read_rt_trylock()
static).
- The test_lockup module failed to compile. Reported by Fernando
Lopez-Lezcano.
- The `kcompactd' daemon together
A bus lock is acquired either through split locked access to
writeback (WB) memory or by using locks to uncacheable (UC) memory
(e.g. direct device assignment). This is typically >1000 cycles slower
than an atomic operation within a cache line. It also disrupts performance
on other cores.

The callers expect disabled preemption/interrupts while invoking
__mod_memcg_lruvec_state(). This works mainline because a lock of
some kind is acquired.
Use preempt_disable_rt() where per-CPU variables are accessed and a
stable pointer is expected. This is also done in __mod_zone_page_state()
for
Retry.

are good candidates for the task before looking for other cpus in the

Change the fr_rx function to make this driver support any Ethertype
when receiving skbs on normal (non-Ethernet-emulating) PVC devices.
(This driver is already able to handle any Ethertype when sending.)
Originally in the fr_rx function, the code that parses the long (10-byte)
header only recogniz
While the traditional irq_work relies on the ability to self-IPI, it
makes sense to provide an unconditional irq_work_queue_remote()
interface.

chip->port_type and chip->pwr_opmode are enums and when GCC considers them
as unsigned, the conditions are never met.
This patch takes advantage of the ret variable and fixes the following
warnings:

The rcu_read_lock/unlock only can guarantee that the memcg will
not be freed, but it cannot guarantee the success of css_get to
memcg.
If the whole process of a cgroup offlining is completed between
reading a objcg->memcg pointer and bumping the css reference on
another CPU, and there are exactly

This patch separates the writing part of the intel-spi drivers
so the 'dangerous' part can be set/unset independently.
This way, the kernel can be configured to include the reading
parts of the driver which can be used without
the dangerous write operations that can turn the system
unbootable.

Hi, Mason, YC Lin,
We'll have to figure out how we can best use the "Command Sequences
to Change to Octal DDR" table.
Would be great if you continue to work on this. One has to
rebase this series on top of v5.10-rc1 with Pratyush's series [1]
applied in advance. Please let me know about your plan

This switches ext4 over to the generic support provided in libfs.
Since casefolded dentries behave the same in ext4 and f2fs, we decrease
the maintenance burden by unifying them, and any optimizations will
immediately apply to both.
