[PATCH] hardcoded errno numbers in assembly code

[PATCH] hardcoded errno numbers in assembly code

[Danilo Piazzalunga]

Hello,

Some assembly code (on various archs) either 
 1. uses hardcoded errno numbers instead of the canonical macro names, or
 2. defines them locally, instead of including the appropriate header (while 
including other headers).

This patch "fixes" such usage in
 - getuser.S for arm, arm26 and i386
 - putuser.S for arm and arm26
 - entry.S for h8300 and sh

Version: 2.6.2-rc1, but applies cleanly to 2.6.1 and 2.6.0.

Cheers,
	Danilo
