From b666f382900c74f23c78556777041c2ceb7c2b24 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Mon, 3 Feb 2014 19:48:52 +0000 Subject: arm64: vdso: update wtm fields for CLOCK_MONOTONIC_COARSE commit d4022a335271a48cce49df35d825897914fbffe3 upstream. Update wall-to-monotonic fields in the VDSO data page unconditionally. These are used to service CLOCK_MONOTONIC_COARSE, which is not guarded by use_syscall.
