Merge branch 'perf/core' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Events can optionally have a modifer by appending a colon and one or

more modifiers.  Modifiers allow the user to restrict when events are

counted with 'u' for user-space, 'k' for kernel, 'h' for hypervisor.

Additional modifiers are 'G' for guest counting (in KVM guests) and 'H'

for host counting (not in KVM guests).

The 'p' modifier can be used for specifying how precise the instruction

address should be. The 'p' modifier is currently only implemented for

tools/perf
