Subject: [PATCH powerpc 0/2] powerpc CONFIG_PREEMPT fixes
Date: Thu, 10 Feb 2011 13:57:10 -0800 [thread overview]
Message-ID: <20110210215710.GA18429@linux.vnet.ibm.com> (raw)
Hello!
This series provides fixes for a couple of CONFIG_PREEMPT problems on
Power:
1. The hpte_need_flush() function accesses per-CPU variables without
protection.
2. The rtas_event_scan() function needs to use raw_smp_processor_id()
to get a starting point to avoid debugging splats.
There are probably a few more where these came from. ;-)
Thanx, Paul
