A processor supports AVX_VNNI instructions if CPUID.(EAX=7,ECX=1):EAX[bit 4]
is present.
This series includes kernel and kvm patches, kernel patch define this
new cpu feature bit and kvm expose this bit to guest. When this bit is
enabled on cpu or vcpu, the cpu feature flag is shown as "avx_vnni"
Expose AVX (VEX-encoded) versions of the Vector Neural Network
Instructions to guest.
The bit definition:
CPUID.(EAX=7,ECX=1):EAX[bit 4] AVX_VNNI
The following instructions are available when this feature is
present in the guest.
1. VPDPBUS: Multiply and Add Unsigned and Signed Bytes

The AMD IOMMU initialisation registers the IRQ remapping domain for
each IOMMU before doing the final sanity check that every I/OAPIC is

This means that the AMD irq_remapping_select() function gets invoked

In general, I agree that the race window is small. However, worst case

Introduce the BLK_MQ_REQ_PM flag. This flag makes the request allocation
functions set RQF_PM. This is the first step towards removing
BLK_MQ_REQ_PREEMPT.

If RPMB is not provisioned, we may see RPMB failure after UFS
suspend/resume. Inject request_sense to clear uac in ufshcd reset flow.

Currently, ufshcd-pci is the only UFS driver with support for
suspend-to-disk PM callbacks (i.e. freeze/thaw/restore/poweroff). These
callbacks are set by the macro SET_SYSTEM_SLEEP_PM_OPS to the same

The expectation for suspend-to-disk is that devices will be powered-off, so
the UFS device should be put in PowerDown mode. If spm_lvl is not 5, then
that will not happen. Change the pm callbacks to force spm_lvl 5

In realtime scenario, We do not want to have interference on the
isolated cpu cores. but when invoking alloc_workqueue() for percpu wq
on the housekeeping cpu, it kick a kworker on the isolated cpu.

As gfs2_quotad_cachep and gfs2_glock_cachep have registered
the shrinker, amending SLAB_RECLAIM_ACCOUNT when creating
them, which make the slab acount to be presiced.

The function ovl_dir_real_file() currently uses the semaphore of the
inode to synchronize write to the upperfile cache field.
However, this function will get called by ovl_ioctl_set_flags(), which
utilizes the inode semaphore too. In this case ovl_dir_real_file() will
try to claim a lock that is
