From: Kees Cook keescook@chromium.org Date: Mon, 16 Oct 2017 16:22:31 -0700 Subject: x86/platform/UV: Convert timers to use timer_setup()

From: Kees Cook keescook@chromium.org

commit 376f3bcebdc999cc737d9052109cc33b573b3a8b upstream.

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.
