SubjectRe: Linux 3.8-rc1: compiling problem in perf-event-p6.o
Date
This didn't happen on 3.6  (3.7 I had no time to check 
out), although I continue to use the same c compiler and
libraries. So it should be caused by any change of the
subroutine perf_event_p6 made in the last time. Also,
everything else of the kernel compiled, just not that
subroutine. Anyway the kernel should compile correctly
with all recent versions of the c compiler, so one should
search and fix that. The maintainer of that subroutine
should be notified, and check the last changes since 3.6 .

Also, I always compile the WHOLE kernel, not only changed
subroutines. Perhaps in any other subroutine was changed
something of global variables in any other subroutine,
what is now incompatible with subroutine perf_event_p6
