In qla2xx_start_scsi_mq() and qla2xx_dif_start_scsi_mq() we grab the
qpair->qp_lock but do access members of the qpair before having the lock.
Re-order the locking sequence to have all read and write access to qpair
members under the qpair->qp_lock.

When swapping out THP (Transparent Huge Page), instead of swapping out

For a THP (Transparent Huge Page), tail_page->mem_cgroup is NULL. So

The function sbi_send is local to just pnd2_edac.c and does not need to
be in global scope, so make it static.

A recent commit included linux/slab.h in linux/irq.h. This breaks the build
of vdso32 on a 64bit kernel.
The reason is that linux/irq.h gets included into the vdso code via
linux/interrupt.h which is included from asm/mshyperv.h. That makes the
32bit vdso compile fail, because slab.h includes the

KM_MAYFAIL didn't have any suitable GFP_FOO counterpart until recently
so it relied on the default page allocator behavior for the given set
of flags. This means that small allocations actually never failed.
Now that we have __GFP_RETRY_MAYFAIL flag which works independently o

__GFP_REPEAT was designed to allow retry-but-eventually-fail semantic to
the page allocator. This has been true but only for allocations requests
larger than PAGE_ALLOC_COSTLY_ORDER. It has been always ignored for
smaller sizes. This is a bit unfortunate because there is no way
