I have found that stable branch 2.6.34 contains a bug when trying to 
build the perf tools. I have a patch but I've not been able to upstream 
it yet, I've copy pasted it inline here, hopefully it doesn't wrap too

     Kernel version 2.6.34.6. has a bug with regards to it's perf tool 
source files. This patch adds a missing include directive.
