'perf diff' currently can only diff symbols(functions).
We should expand it to diff cycles of individual programs blocks as
reported by timed LBR. This would allow to identify changes in specific
code accurately.
We need a new structure to maintain the basic block information, su

We will expand perf diff to support diff cycles of individual programs
blocks, so it requires all data files having branch stacks.
This patch checks HEADER_BRANCH_STACK in header, and only set the flag
has_br_stack when HEADER_BRANCH_STACK are set in all data files.

The block_info contains the program basic block information, i.e,
contains the start address and the end address of this basic block and
how much cycles it takes.
We need to compare, sort and even print out the basic block by some
orders, i.e. sort by cycles.
For this purpose, we
During our torturing on numa stuff, we found problems like:
* missing per-cgroup information about the per-node execution status
* missing per-cgroup information about the numa locality
That is when we have a cpu cgroup running with bunch of tasks, no good
way to tell how it's tasks are deali

Hi all,
Today's linux-next merge of the block tree got a conflict in:
fs/xfs/xfs_aops.c
between commit:
a24737359667 ("xfs: simplify xfs_chain_bio")
from the xfs tree and commit:
79d08f89bb1b ("block: fix .bi_size overflow")
from the block tree.
I fixed it up (see below) and can carry

Sure, that's pretty trivial to do. Or what I was thinking, try it if it
fails:

There are two typos leading to pp2 and pp4 as well as ppmmu2 and ppmmu4
incorrectly sharing the same interrupt line.
