Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64
Pull arm64 changes from Catalin Marinas:
"arm64 fixes:
- Use swiotlb_init() instead of swiotlb_init_with_default_size().
The latter is now a static function (commit 74838b75379a "swiotlb:
add the late swiotlb initialization function with iotlb memory").
- Enable interrupts before calling do_notify_resume().
arm64 clean-up:
- Use the generic implementation of compat_sys_sendfile() on arm64 as
commit 8f9c0119d7ba (introducing the function) has been merged."
