This patch series are for enabling the asynchronous threads for the phases
resume_noirq, resume_early, suspend_noirq and suspend_late.

In a multiplatform scenario, it is possible that multiple serial
drivers are part of the kernel. Currently the driver registration fails
if multiple serial drivers with same default major/minor numbers are
included in the kernel. A typical case is observed with amba-pl011 and
samsung-uart drivers.
uart_register_driver call binds the driver to a specific device
node through tty_register_driver call. This should typically happen
during device probe call.

Hi folks
I have a program which is trying to read a page from the page cache
for a certain file
it calls mmap (PROT_NONE, MAP_SHARED |MAP_LOCKED).
Then it calls mincore to check if the page is in memory
If it does exist, it remaps the same offset using mmap(PROT_READ,
MAP_SHARED|MAP_LOCKED)

In the current code, extents would not delete from the bl_extents list when
lseg is removed from layout. Now one extent's lseg is deleted and its type
is PNFS_BLOCK_NONE_DATA, while a layoutget request get a extent with the same
range and its type is PNFS_BLOCK_NONE_DATA. In this situation the fu

This looks like a bug. copy_to_user_* shouldn't take mmap_sem at all
Check the might_fault annotation used in generic code. Arm version of

When OOM happen, will dump buddy free areas info, hugetlb pages info,
memory state of all eligible tasks, per-cpu memory info.
But do not dump slab/vmalloc info, sometime, it's not enough to figure out the
reason OOM happened.
So, my questions are:
1. Should dump slab/vmalloc info when OOM happen?

As the orphan_blocks may be max to 504, so it is not security
