Date: Tue, 19 Apr 2011 13:08:40 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...nel.org Cc: stable-review@...nel.org, torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, "David S. Miller" <davem@...emloft.net> Subject: [31/70] sparc32: Fix might-be-used-uninitialized warning in do_sparc_fault(). 2.6.38-stable review patch. If anyone has any objections, please let us know. ------------------ From: David S. Miller <davem@...emloft.net> [ Upstream commit c816be7b5f24585baa9eba1f2413935f771d6ad6 ] When we try to handle vmalloc faults, we can take a code path which uses "code" before we actually set it. Amusingly gcc-3.3 notices this yet gcc-4.x does not. Reported-by: Bob Breuer <breuerr@...net> Signed-off-by: David S.
