Subject: [PATCH] arm64: remove bogus TASK_SIZE_64 check
Date: Mon, 26 Oct 2015 12:53:17 +0900	[thread overview]
Message-ID: <1445831597-5680-1-git-send-email-ard.biesheuvel@linaro.org> (raw)

The comparison between TASK_SIZE_64 and MODULES_VADDR does not
make any sense on arm64, it is simply something that has been
carried over from the ARM port which arm64 is based on. So drop it.
