android: ion: push cma heap to kmemleak_ignore
A reserved memory allocated by memblock is traceable by kmemleak. It
also applies to CMA areas. But CMA areas are different from other
reserved memories. They are unreserved after the kmem is initialized.
It means that the pages in CMA areas are not allocated/reserved once
all pages in CMA areas are returned to the kernel page allocator.
Therefore a reserved memory to be a CMA area should be ignored by
kmemleak.

[COMMON] kernel: watchdog: detect hard lockups without NMIs using secondary cpus
Emulate NMIs on systems where they are not available by using timer
interrupts on other cpus. Each cpu will use its softlockup hrtimer
to check that the next cpu is processing hrtimer interrupts by
verifying that a counter is increasing.
This patch is useful on systems where the hardlockup detector is not
available due to a lack of NMIs, for example most ARM SoCs.
Without this patch any cpu stuck with interrupts disabled can
cause a hardware watchdog reset with no debugging information,
but with this patch the kernel can detect the lockup and panic,
which can result in useful debugging info.

oom_killer selectes a victim task with the combination of the total

The patch series of "Support non-lru page migration"
(https://lwn.net/Articles/689343/) introduced the way of migrating
movable pages which are not in LRU list by providing callback
functions called on migration. With that patch series, zsmalloc()
starts allocating pages from Movable zone even though it it is not LRU
pages. Therefore HPA should check if a page is non-lru movable.
Otherwise, HPA may suffer from lack of pages to migrate to other

signals SIGKILL the victim task and expects the victim task to be soon

HPA Killer skips selecting another task on the next invocation until
the victim task is finally died during a second unless it finds
another victim task that is more proper to kill. If the task is not
died in a second, HPA killer is to select the same task as a victim
because of the victim selection logic.
If the victim task is in disk sleep state and it waits for a resource
that is occupied by the task that invoking HPA Killer, HPA Killer will
be never finished until another larger task with higher oom_adj is
appeared.
To end ths dead-lock condition, HPA Killer should select next proper
victim task even though the current victim task is not died.
