commit: 97d21003df3e7504c899b1701546f18ff475966f [8/11] x86/platform/UV: Add check of TSC state set by UV BIOS
config: x86_64-randconfig-b0-10211156 (attached as .config)
compiler: gcc-4.4 (Debian 4.4.7-8) 4.4.7
reproduce:
        git checkout 97d21003df3e7504c899b1701546f18ff475966f
        # save the attached .config to linux build tree
        make ARCH=x86_64 

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x4223a): Section mismatch in reference from the function uv_tsc_check_sync() to the function .init.text:uv_early_read_mmr()
   The function uv_tsc_check_sync() references
   the function __init uv_early_read_mmr().
   This is often because uv_tsc_check_sync lacks a __init
   annotation or the annotation of uv_early_read_mmr is wrong.
