Subject: [V5 0/4] perf: New conditional branch filter

Hello Arnaldo,

	I had posted the V5 version of PowerPC SW branch filter enablement
patchset last month. Please find the patchset here at

	https://lkml.org/lkml/2014/2/5/79

These following patches (2,4,5,6 patches from the original V5 version patchset)
are the ones which change code in the generic kernel, perf tool and X86 perf.
Basically this patchset adds one more branch filter for "conditional" branches.
In X86 code, this new filter has been implemented with the help of availble SW
filter X86_BR_JCC and LBR_JCC. We had some discussions in this regard before.
Please review these changes and if it's okay, please merge them. Other patches
in the series are powerpc specific and are being reviewed by Benjamin Herrenschmidt
and Michael Ellerman. Let me know if you need more information.
