Subject: re: Linux 2.6.30-rc2: [PATCH] ARM OABI compatibility: fix build
	error

Building for ARM with CONFIG_OABI_COMPAT enabled fails due to a
missing include:

arch/arm/kernel/sys_oabi-compat.c: In function 'sys_oabi_epoll_wait':
arch/arm/kernel/sys_oabi-compat.c:288: error: implicit declaration of
function 'kmalloc'
arch/arm/kernel/sys_oabi-compat.c:288: error: 'GFP_KERNEL' undeclared
(first use in this function)
arch/arm/kernel/sys_oabi-compat.c:288: error: (Each undeclared
identifier is reported only once
arch/arm/kernel/sys_oabi-compat.c:288: error: for each function it
appears in.)
arch/arm/kernel/sys_oabi-compat.c:288: warning: assignment makes
pointer from integer without a cast
arch/arm/kernel/sys_oabi-compat.c:301: error: implicit declaration of
function 'kfree'
arch/arm/kernel/sys_oabi-compat.c: In function 'sys_oabi_semtimedop':
arch/arm/kernel/sys_oabi-compat.c:324: error: 'GFP_KERNEL' undeclared
(first use in this function)
arch/arm/kernel/sys_oabi-compat.c:324: warning: assignment makes
pointer from integer without a cast
make[1]: *** [arch/arm/kernel/sys_oabi-compat.o] Error 1
make: *** [arch/arm/kernel] Error 2

including linux/mm.h fixes this (thanks to Bill Gatliff for the pointer)
