Subject: [PATCH] Get rid of arch_free_page() warning
Date: Tue, 14 Dec 2004 20:14:00 +0000	[thread overview]
Message-ID: <16679.1103055240@redhat.com> (raw)


The attached patch gets rid of a warning produced when compiling
mm/page_alloc.c if the arch doesn't supply its own arch_free_page().

The problem is that there's one place in there that ignores the return value
of this function, and so you get a warning from gcc about an ineffectual
statement.
