    Subjectre: 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)
