From 65ea5b0349903585bfed9720fa06f5edb4f1cd25 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 30 Jan 2008 13:30:56 +0100 Subject: x86: rename the struct pt_regs members for 32/64-bit consistency We have a lot of code which differs only by the naming of specific members of structures that contain registers. In order to enable additional unifications, this patch drops the e- or r- size prefix from the register names in struct pt_regs, and drops the x- prefixes for segment registers on the 32-bit side. This patch also performs the equivalent renames in some additional places that might be candidates for unification in the future. Signed-off-by: H.
