From beb526b12134a6b6744125deec5a7fe24a8f92e3 Mon Sep 17 00:00:00 2001 From: Samuel Seay Date: Wed, 2 Jan 2013 10:53:46 +0000 Subject: PPC: fix segfault in signal handling code Removed h2g() macro around the ka->_sa_handler due to the _sa_handler being a guest memory address. Changed the __put_user to put_user as it was attempting to put a value at the stack address but the new address is a guest memory address, __put_user is for host memory addresses.
