+Subject: x86-64: Replace left over sti/cli in ia32 audit exit code
+
+From: Jan Beulich <JBeulich@suse.com>
+
+commit 40a1ef95da85843696fc3ebe5fce39b0db32669f upstream.
+
+For some reason they didn't get replaced so far by their
+paravirt equivalents, resulting in code to be run with
+interrupts disabled that doesn't expect so (causing, in the
+observed case, a BUG_ON() to trigger) when syscall auditing is
+enabled.
+
+David (Cc-ed) came up with an identical fix, so likely this can
+be taken to count as an ack from him.
