Commit cbc9565ee826 ("powerpc: Remove ksp_limit on ppc64") moved
PPC32 ksp_limit handling in assembly functions call_do_softirq()
and call_do_irq() as they are different for PPC32 and PPC64.
In preparation of replacing these functions by inline assembly,
partialy revert that commit to bring back k
call_do_irq() and call_do_softirq() are quite similar on PPC32 and
PPC64 and are simple enough to be worth inlining.
Inlining them avoids an mflr/mtlr pair plus a save/reload on stack.
This is inspired from S390 arch. Several other arches do more or
less the same. The way sparc arch does seems od

Hi All:
In function sata_rcar_bmdma_fill_sg, macro for_each_sg uses sg_next(),
which could return NULL as "sg", however, there's no check before
dereferencing it (in sg_dma_address()), which is potentially unsafe.

More than one gpio controllers can share one interrupt, change the
driver to request shared irq.
While this will work, it will mess up userspace accounting of the number
of interrupts per second in tools such as vmstat. The reason is that

Hi, Qian, Shakeel
Thanks for testing.
Sounds I missed some case to handle. anon_vma_clone() now would be called in
vma_adjust, which is a different case when it is introduced.
BTW, do you have the specific test case? So that I could verify my change. The
kernel build test doesn't trigger this.
