From bbbfde782084b4f0d85ddffb88f1cf4650ff40e4 Mon Sep 17 00:00:00 2001 From: John David Anglin Date: Sat, 4 May 2013 19:16:41 +0000 Subject: [PATCH] parisc: use long branch in fork_like macro 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.
