From 0cc0213e73af5963eca259c84876937c20689dbd Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 31 Aug 2009 14:23:29 -0700 Subject: x86, msr: Have the _safe MSR functions return -EIO, not -EFAULT For some reason, the _safe MSR functions returned -EFAULT, not -EIO. However, the only user which cares about the return code as anything other than a boolean is the MSR driver, which wants -EIO. Change it to -EIO across the board. Signed-off-by: H.
