Subject: [IA64] Delete a redundant instruction in unaligned_access
X-Git-Tag: v2.6.16-rc6~141^2~8
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=5d1a88af826b03edaac4d2bd2f25af56a54f26e6;p=linux-2.6-omap-h63xx.git

[IA64] Delete a redundant instruction in unaligned_access

unaligned_access does fetch cr.ipsr, then calls
dispatch_unaligned_handler, but dispatch_unaligned_handler fetches
cr.ipsr again, so delete the first one.
