[RFC][PATCH 0/2] perf vs d-cache aliasses

[Peter Zijlstra]

Hi David,

based on your vmalloc code, an alternative implementation that lets x86 stay
with regular allocations.

While I'm sad to have to propose having two implementations around, I see no
other way to please both sides.

Alternative to placing the code in arch/sparc we could do something like

CONFIG_PERF_WANTS_VMALLOC and place both somewhere in kernel/
