Subject: [build bug] x86_64, -git: Error: unknown pseudo-op: `.cfi_signal_frame'


using latest -git i'm getting this build bug on gcc 3.4:

 arch/x86_64/kernel/entry.S: Assembler messages:
 arch/x86_64/kernel/entry.S:157: Error: unknown pseudo-op: `.cfi_signal_frame'
 arch/x86_64/kernel/entry.S:215: Error: unknown pseudo-op: `.cfi_signal_frame'
 arch/x86_64/kernel/entry.S:333: Error: unknown pseudo-op: `.cfi_signal_frame'
 arch/x86_64/kernel/entry.S:548: Error: unknown pseudo-op: `.cfi_signal_frame'

 gcc version 3.4.0 20040129 (Red Hat Linux 3.4.0-0.3)

using gcc 4.1 it doesnt happen

 gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)

this is caused by the following commit:

 commit adf1423698f00d00b267f7dca8231340ce7d65ef
 Author: Jan Beulich <jbeulich@...ell.com>
 Date:   Tue Sep 26 10:52:41 2006 +0200

reverting that patch solves the build problem and the resulting kernel 
builds and boots fine.
