arm64: memory: Add missing brackets to untagged_addr() macro
Add brackets around the evaluation of the 'addr' parameter to the untagged_addr() macro so that the cast to 'u64' applies to the result of the expression. Cc: <stable@vger.kernel.org> Fixes: 597399d0cb91 ("arm64: tags: Preserve tags for addresses translated via TTBR1") Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Will Deacon <will@kernel.org>
