Merge branch 'perf/annotate' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Perf annotate browser improvements:
- Get back the line separating the overheads from the disassembly, requested by
Peter Zijlstra, Linus agreed now that it is a solid line and more column real
state was harvested. Also it has the jump->arrow lines separated from it by
the address/jump target column.
- Don't change asm line color when toggling source code view. Requested by
Peter Zijlstra.
