The compilation fails for UP-kernel. The __wake_up_sync is 
only defined for CONFIG_SMP, so it failed for UP.

kernel/built-in.o(.text+0x116ea): In function `futex_wake':
: undefined reference to `__wake_up_sync'
kernel/built-in.o(.text+0x11904): In function `futex_requeue':
: undefined reference to `__wake_up_sync'
make: *** [vmlinux] Error 1
