ION system heap keeps pages in its pool for better performance. When the
system is under memory pressure, slab shrinker calls the callback
registered and then the pages pooled get freed.
When the shrinker is called, it checks gfp_mask and determines whether
the pages from highmem need to be freed
ION system heap creates a temporary list of pages to build
scatter/gather table, introducing an internal data type, page_info. Now

Using compound pages relieves burden on tracking the meta information

This patch is trying to fix a kernel crash bug.
When kernel boots on a HP large system, it crashes.
The reason is when blk_rq_init is called, the second parameter rq , which
is a member as q->flush_rq, is NULL. Kernel does not allocate space for it.
This fix adds an alloc for flush_rq member when
The callback is invoked when process is scheduled in or out.
It provides mechanism for later patches to save/store the LBR
stack. For the schedule in case, the callback is invoked at
the same place that flush branch stack callback is invoked.
So it also can replace the flush branch stack callback.
This patch series implements large PEBS interrupt threshold. For some
limited cases, it can significantly reduce the sample overhead. Please
read patch 6's commit message for more information.

Yan, Zheng
