This patch fixes below build error by adding the missing asm/memory.h, which is needed for arch_is_coherent().
$ make pxa3xx_defconfig; make CC init/do_mounts_rd.o In file included from include/linux/list_bl.h:5, from include/linux/rculist_bl.h:7, from include/linux/dcache.h:7, from include/linux/fs.h:381, from init/do_mounts_rd.c:3: include/linux/bit_spinlock.h: In function 'bit_spin_unlock': include/linux/bit_spinlock.h:61: error: implicit declaration of function 'arch_is_coherent' make[1]: *** [init/do_mounts_rd.o] Error 1 make: *** [init] Error 2
