arm64 fixes

Hi Linus,

Please pull the tag below. There are two fixes and removal of the arm64-specific compat_sys_sendfile (I pushed the generic implementation separately and it now got into mainline). Thanks.

The following changes since commit e9eca4de957ac33744fb994ccacd4a5102e445a8:

arm64: Enable interrupts before calling do_notify_resume() (2012-10-08 18:04:21 +0100)

----------------------------------------------------------------
AArch64 fixes:
- Use swiotlb_init() instead of swiotlb_init_with_default_size(). The latter is now a static function (commit 74838b7 "swiotlb: add the late swiotlb initialization function with iotlb memory").
- Enable interrupts before calling do_notify_resume().

AArch64 clean-up:
- Use the generic implementation of compat_sys_sendfile() on arm64 as commit 8f9c0119 (introducing the function) has been merged.
