Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- #ifdef CONFIG_EFI around __efi_fpsimd_begin/end
- Assembly code alignment reduced to 4 bytes from 16
- Ensure the kernel is compiled for LP64 (there are some arm64
compilers around defaulting to ILP32)
- Fix arm_pmu_acpi memory leak on the error path
