Subject: [PATCH] Partially revert patch that encloses asm-offset.h numbers
 in brackets

Partially revert patch:

	commit 3234282f33b29d349bcada40204fc7c8fda7fe72
	Author: Jan Beulich <JBeulich@...ell.com>
	Date:   Tue Oct 19 14:52:26 2010 +0100
	x86, asm: Fix CFI macro invocations to deal with shortcomings in gas

This breaks MN10300 arch as this changes many instances of instructions
similar to the following:

	MOV	number,D0

which represents an immediate value load into:

	MOV	(number),D0

which the assembler then interprets as a load from absolute address.

arch/mn10300/kernel/entry.S:64: Error: Invalid opcode/operands
arch/mn10300/kernel/entry.S:65: Error: junk at end of line, first unrecognized character is `0'
arch/mn10300/kernel/entry.S:74: Error: Invalid opcode/operands
arch/mn10300/kernel/entry.S:74: Error: junk at end of line, first unrecognized character is `1'
arch/mn10300/kernel/entry.S:75: Error: Invalid opcode/operands
arch/mn10300/kernel/entry.S:76: Error: junk at end of line, first unrecognized character is `0'
