Date: Fri, 17 May 2013 14:36:53 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, John David Anglin <dave.anglin@...l.net>, Helge Deller <deller@....de> Subject: [ 098/102] parisc: use long branch in fork_like macro 3.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: John David Anglin <dave.anglin@...l.net> commit bbbfde782084b4f0d85ddffb88f1cf4650ff40e4 upstream. The "b" branch instruction used in the fork_like macro only can handle 17-bit pc-relative offsets. This fails with an out of range offset with some .config files. Rewrite to use the "be" instruction which can branch to any address in a space.
