Russell King 0d782dc430 ARM: VFP: fix vfp thread init bug and document vfp notifier entry conditions ... When the VFP notifier is called for flush_thread(), we may be preemptible, meaning we might migrate to another CPU, which means referencing the current CPU number without some form of locking is invalid, and can cause data corruption. For the most cases, this isn't a problem since atomic notifiers are run under rcu lock, which for most configurations results in preemption being disabled - except when the preemptable tree-based rcu implementation is selected. Let's make it safe anyway. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>		2009-12-13 16:33:19 +00:00
