To fix:
In file included from arm/boot/compressed/misc.c:28:0:
arm/mach-msm/include/mach/uncompress.h: In function 'putc':
arch/arm/mach-msm/include/mach/uncompress.h:48:3: error: implicit
declaration of function 'smp_mb' [-Werror=implicit-function-declaration]
The putc does a cpu_relax which for this platform is smp_mb.
