Subject: sparc64: Use xcall_deliver() consistently.
X-Git-Tag: v2.6.27-rc2~41^2~10
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=622824dbb536f7bdc241eefc3e1ae31c463b4eb8;p=linux-2.6-omap-h63xx.git

sparc64: Use xcall_deliver() consistently.

There remained some spots still vectoring to the appropriate
*_xcall_deliver() function manually.
