Strangely it applies against

git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-tip tip

auto-perf-next: add perf/lock

without any offsets even:

~/lsrc/git/x86/linux-2.6-tip> patch -p1 --dry-run < ~/lsrc/linux-2.6.32-ak/patches/perf-kernelsrc

patching file tools/perf/util/include/linux/poison.h
patching file tools/perf/util/include/linux/rbtree.h
patching file tools/perf/util/util.h

Looks like tip is the same as .32 in this regard or I tried the wrong
tree.

There's a reject against Linus' latest. I'm appending a patch that applies
cleanly there. Also that tree seems to have gained a lot of new
../..s; I fixed those too, except those that do not go outside
the perf directory tree.

The other version number patch applies in both cases, just with some offsets.

perf: Make location of kernel source configurable

tools/perf has no support for separate object directories
and lots of hard coded paths assuming that the kernel source
is always in ../..

As a first step of compiling it separately without messing
up clean source trees allow to configure the kernel source
location using a KERNELSRC variable

This allows at least to copy the whole tools/perf
directory elsewhere and build it separately.

The default is still ../.., so for a standard build
nothing changes

This also removes a lot of ugly ../.. from the source.
