From 18b246fa60dd4bfc71c78d669e2ffaa5df454d6a Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 22 Feb 2012 16:48:32 +1100 Subject: powerpc: Fix various issues with return to userspace We have a few problems when returning to userspace. This is a quick set of fixes for 3.3, I'll look into a more comprehensive rework for 3.4. This fixes: - We kept interrupts soft-disabled when schedule'ing or calling do_signal when returning to userspace as a result of a hardware interrupt. - Rename do_signal to do_notify_resume like all other archs (and do_signal_pending back to do_signal, which it was before Roland changed it). - Add the missing call to key_replace_session_keyring() to do_notify_resume().
