Subject[PATCH] [1/2] perf: Make location of kernel source configurable
Date

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.
