Hi all,
Here are my warnings and section mismatches when compiling 2.6.28-rc6-git1 kernel. All are fixed in git trees but patches are not yet pulled in mainline.
Regards.
arch/x86/kernel/cpu/mtrr/main.c: In function ‘mtrr_cleanup’: arch/x86/kernel/cpu/mtrr/main.c:1363: attention : ‘gran_factor’ may be used uninitialized in this function arch/x86/kernel/cpu/mtrr/main.c:1364: attention : ‘gran_base’ may be used uninitialized in this function

If init_thread_xstate is only used by fpu_init then annotate init_thread_xstate with a matching annotation.

This is often because notify_cpu_starting lacks a __cpuinitdata annotation or the annotation of cpu_chain is wrong.
