Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas: - Ensure that the compiler and linker versions are aligned so that ld doesn't complain about not understanding a .note.gnu.property section (emitted when pointer authentication is enabled). - Force -mbranch-protection=none when the feature is not enabled, in case a compiler may choose a different default value. - Remove CONFIG_DEBUG_ALIGN_RODATA. It was never in defconfig and rarely enabled. - Fix checking 16-bit Thumb-2 instructions checking mask in the emulation of the SETEND instruction (it could match the bottom half of a 32-bit Thumb-2 instruction). * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: armv8_deprecated: Fix undef_hook mask for thumb setend arm64: remove CONFIG_DEBUG_ALIGN_RODATA feature arm64: Always force a branch protection mode when the compiler has one arm64: Kconfig: ptrauth: Add binutils version check to fix mismatch init/kconfig: Add LD_VERSION Kconfig
