Tried master:
250d8 Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
and v3.6-rc7
with omap2plus_defconfig + CONFIG_BOOTTIME enabled:

init/boottime.c:47:9: error: ?cpu_usage_stat? defined as wrong kind of tag
init/boottime.c:47:24: error: array type has incomplete element type
init/boottime.c: In function ?boottime_mark_core?:
init/boottime.c:127:313: error: ?struct kernel_stat? has no member named ?cpustat?
init/boottime.c:128:311: error: ?struct kernel_stat? has no member named ?cpustat?
init/boottime.c:129:313: error: ?struct kernel_stat? has no member named ?cpustat?
init/boottime.c:130:310: error: ?struct kernel_stat? has no member named ?cpustat?

if it depended on some other patch or a specific maintainer branch,
it was'nt clear.
