Subject: [RFC][PATCH 0/2] perf vs d-cache aliasses
Date: Mon, 21 Sep 2009 16:08:48 +0200 [thread overview]
Message-ID: <20090921140848.444528343@chello.nl> (raw)
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/
