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
