proc.5: Document /proc/sys/vm/compact_memory
...
Since 2.6.36 [1] CONFIG_COMPACTION is supported in Linux (for a
detailed explanation see [2]). But in essence the contents of
/proc/buddyinfo shows how much contiguous areas of a certain
size are available. These numbers are not actually up to date
as the Linux kernel will implicitly trigger compaction
(+- defragmentation) when an allocation is done. This makes it
difficult since you can't predict upfront whether or not a large
allocation will succeed or not. By using
/proc/sys/vm/compact_memory you can explicitly trigger compaction
to occur and /proc/buddyinfo will give a more realistic view on
the available memory in contiguous areas.
This patch updates proc.5 to explain the usage of this file and is
inspired by Documentation/systcl/vm.txt [3]

perf_event_open.2: Clarify description of overflow events
...
Update the perf_event_open manpage to be more consistent when
discussing overflow events. It merges the discussion of
poll-type notifications with those generated by SIGIO
signal handlers.
This addresses the remaining FIXMEs is the document.

perf_event_open.2: Remove innaccurate paragraph describing attr.config
...
Remove an inaccurate paragraph about values in the attr.config
field. This information was never true in any released kernel;
it somehow snuck into the manpage because it is still described
this way in tools/perf/design.txt in the kernel source tree.
