From: Sam Ravnborg Date: Wed, 29 Apr 2009 07:47:26 +0000 (+0200) Subject: x86, vmlinux.lds: unify parainstructions X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ae61836289a415351caa524d328110aaeae100d4;p=openwrt%2Fstaging%2Fblogic.git x86, vmlinux.lds: unify parainstructions 32 bit: - increase alignment from 4 to 8 for .parainstructions - increase alignment from 4 to 8 for .altinstructions 64 bit: - move ALIGN() outside output section for .altinstructions None of the above should result in any functional change.
