[Sukadev Bhattiprolu] If verbose option is set, print help message
if a required parameter is missing or invalid parameter is specified.
From: Cody P Schafer
Ian pointed out the use of __aligned(4096) caused rather large stack
consumption in single_24x7_request(), so use the kmem_cache
hv_page_cache (which we've already got set up for other allocations)
insead of allocating locally.

Cody P Schafer (3):
powerpc/perf/hv-24x7: use kmem_cache instead of aligned stack
allocations
perf Documentation: sysfs events/ interfaces
perf Documentation: remove duplicated docs for powerpc cpu specific
events
Sukadev Bhattiprolu (1):
Simplify
arbitrary event file contents.

buffer. Each call to catalog_read() returns at most one 4K page.
Given these requirements, we should be able to simplify the
catalog_read().

Powerpc, we can skip the --events-file option
and run:
perf stat -e PM_CYC sleep 1

What this patchset does:
- the first patch (override sysfs in tools/perf via SYSFS_PATH) was sent out
previously, but needed a resend anyhow. Having it is useful for testing the
later changes to tools/perf.
- the second patch is a bugfix to the powerpc hv-24x7 code w
