well.. I know 2.6.35-rc6-00191-ga2dccdb builds without any such 
errors..(I can bisect this if need be)

keep in mind this happens with: gcc --version
gcc (GCC) 4.6.0 20100416 (experimental)

                  from include/linux/hardirq.h:10,
                  from kernel/perf_event.c:26:
include/linux/irq.h: In function 'alloc_desc_masks':
include/linux/irq.h:442:8: warning: variable 'gfp' set but not used
kernel/perf_event.c: At top level:
kernel/perf_event.c:5879:1: internal compiler error: in 
cgraph_estimate_size_after_inlining, at ipa-inline.c:208
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make[1]: *** [kernel/perf_event.o] Error 1
make: *** [kernel] Error 2


just tested on my other machine running
gcc --version: gcc (GCC) 4.6.0 20100731 (experimental)
and this does not occur. kernel builds fine.(not sure with other 
versions of gcc though).
