Subject: ia64: rename partial_page
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
In file included from include/linux/net.h:23,
from include/net/scm.h:5,
from arch/ia64/ia32/sys_ia32.c:62:
include/linux/splice.h:42: error: redefinition of `struct partial_page'
Jens has added a partial_apge thing in splice whcih conflicts with the ia64
one. Rename ia64 out of the way. (ia64 chose poorly).
