[PATCH] Get rid of most of the remaining k*alloc() casts.

From: Robert P. J. Day
Date: Tue Dec 19 2006 - 06:36:45 EST


Get rid of the remaining obvious pointer casts of all k[cmz]alloc
calls, and do a little whitespace cleanup on the result, based on the
CodingStyle file.

Signed-off-by: Robert P. J. Day <rpjday@xxxxxxxxxxxxxx>

since this patch hits a range of files, i'm just throwing it out
there. some folks might want to tweak it further.
