Subject: [GIT pull] perf fixes for 4.12
Date: Sun, 25 Jun 2017 11:38:29 +0200 (CEST)	[thread overview]
Message-ID: <alpine.DEB.2.20.1706251129170.1996@nanos> (raw)

[-- Attachment #1: Type: text/plain, Size: 2602 bytes --]

Linus,

please pull the latest perf-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus

Three fixlets for perf:

  - Return the proper error code if aux buffers for a event are not
    supported.

  - Calculate the probe offset for inlined functions correctly

  - Update the Skylake DTLB load/store miss event so it can count 1G TLB
    entries as well.

Thanks,

	tglx
