From 3eb8057bbafc64dbf09d5c18513aa80c1b7f2fcb Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 21 Jan 2009 21:30:23 -0800 Subject: sparc64: Move generic PCR support code to seperate file. It all lives in the oprofile support code currently and we will need to share this stuff with NMI watchdog and perf_counter support. Signed-off-by: David S.
