| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Jiri Slaby <jirislaby@gmail.com>
commit 7aed55d1085f71241284a30af0300feea48c36db upstream.
Impact: fix debug/crash printout
Since errorcode is popped out, RIP is on the top of the stack. Use real RIP value instead of wrong CS.
