From 40faf463e62de0b29722910eded7dd26cd8b684b Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Tue, 24 Jun 2008 11:37:57 -0300 Subject: x86: introduce __ASM_REG macro. There are situations in which the architecture wants to use the register that represents its word-size, whatever it is. For those, introduce __ASM_REG in asm.h, along with the first users _ASM_AX and _ASM_DX. They have users waiting for it, namely the getuser functions. Signed-off-by: Glauber Costa Signed-off-by: H.
