From 5e3e27637959155bf3b06f52c5fbe9e9b0ffbdfe Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 12 Nov 2013 20:56:02 +0100 Subject: ARM: netx: stop using mach/timex.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit mach/timex.h is the last remaining header that is unused for multiarch builds but necessary for singlearch builds. To allow to get rid of it for singlearch builds, too, drop its usage in netx arch code by substituting CLOCK_TICK_RATE and LATCH by a local cpp symbol.
