From 34f2c0ac111aaf090c7d2432dab532640870733a Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sun, 1 Apr 2012 16:38:46 -0400 Subject: tile: fix multiple build failures from system.h dismantle Commit bd119c69239322caafdb64517a806037d0d0c70a "Disintegrate asm/system.h for Tile" created the asm/switch_to.h file, but did not add an include of it to all its users. Also, commit b4816afa3986704d1404fc48e931da5135820472 "Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h" introduced the concept of asm/cmpxchg.h but the tile arch never got one. Fork the cmpxchg content out of the asm/atomic.h file to create one.
