Subject[PATCH] xen: fix section usage in xen-head.S
Failing to specify "ax" in the pushsection caused ld to generate
an additional section for .init.text appending a number.

A side effect of this was a section mismatch warning because modpost
did not recognize a .init.text section named .init.text.1:
WARNING: vmlinux.o(.text.head+0x247): Section mismatch: reference to .init.text.1:start_kernel (between 'is386' and 'check_x87')

Fix this by hardcoding the "ax" in the pushsection.
Thanks to Torlaf for reporting this.

Alan Modra @ binutils provided the hint that made me
able to locate the root cause of this warning.
