include/linux/cred.h: fix build
mips allmodconfig: include/linux/cred.h: In function `creds_are_invalid': include/linux/cred.h:187: error: `PAGE_SIZE' undeclared (first use in this function) include/linux/cred.h:187: error: (Each undeclared identifier is reported only once include/linux/cred.h:187: error: for each function it appears in.) Fixes commit b6dff3ec5e116e3af6f537d4caedcad6b9e5082a Author: David Howells <dhowells@redhat.com> AuthorDate: Fri Nov 14 10:39:16 2008 +1100 Commit: James Morris <jmorris@namei.org> CommitDate: Fri Nov 14 10:39:16 2008 +1100 CRED: Separate task security context from task_struct I think. It's way too large to be inlined anyway. Dunno if this needs an EXPORT_SYMBOL() yet.
