Subject[patch 70/74] Make sock_sendpage() use kernel_sendpage()
2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Linus Torvalds <torvalds@linux-foundation.org>

commit e694958388c50148389b0e9b9e9e8945cf0f1b98 upstream.

kernel_sendpage() does the proper default case handling for when the
socket doesn't have a native sendpage implementation.

Now, arguably this might be something that we could instead solve by
just specifying that all protocols should do it themselves at the
protocol level, but we really only care about the common protocols.
Does anybody really care about sendpage on something like Appletalk? Not
likely.
