From db413b51c0d023b336634ffbf5eb29128245df8d Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Tue, 24 May 2016 18:55:40 +0100 Subject: arm64: Remove orphaned __addr_ok() definition Since commit 12a0ef7b0ac3 ("arm64: use generic strnlen_user and strncpy_from_user functions"), the definition of __addr_ok() has been languishing unused; eradicate the sucker.
