* FRV: Fix the new-style kernel_thread() stuffDavid Howells2012-11-021-2/+3
| | | | | | | | | | | | | | | | | | | | The kernel_thread() changes for FRV don't work, and FRV fails to boot, starting with: commit 02ce496f152df87be081a64796498942c433a2fd Author: Al Viro <viro@zeniv.linux.org.uk> Date: Tue Sep 18 22:18:51 2012 -0400 Subject: frv: split ret_from_fork, simplify kernel_thread() a lot The problem is that the userspace registers are completely cleared when a kernel thread is created and all subsequent user threads are then copied from that. Unfortunately, however, the TBR and PSR registers are restored from the pt_regs and the values they should be set to are clobbered by the memset. Instead, copy across the old user registers as normal, and then merely alter GR8 and GR9 in it if we're going to execute a kernel thread. Signed-off-by: David Howells <dhowells@redhat.com>
* FRV: Fix the preemption handlingDavid Howells2012-11-021-1/+1
| | | | | | | | | | | | | | | Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is incorrectly loaded into the threadinfo flags rather than the threadinfo preemption count. Unfortunately, the code cannot be simply converted to use preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to cut down on the cost of actually disabling interrupts and thus local_irq_enable() doesn't actually enable interrupts.

* | frv: Add missing RCU idle APIs on idle loopFrederic Weisbecker2012-09-231-0/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | In the old times, the whole idle task was considered as an RCU quiescent state. But as RCU became more and more successful overtime, some RCU read side critical section have been added even in the code of some architectures idle tasks, for tracing for example. So nowadays, rcu_idle_enter() and rcu_idle_exit() must be called by the architecture to tell RCU about the part in the idle loop that doesn't make use of rcu read side critical sections, typically the part that puts the CPU in low power mode. This is necessary for RCU to find the quiescent states in idle in order to complete grace periods. Add this missing pair of calls in the Frv's idle loop. Reported-by: Paul E.

All architectures converted to it; block_sigmask() itself is gone now (merged into this one). I'm still not too happy with the signature, but that's a separate story (IMO we need a structure that would contain signal number + siginfo + k_sigaction, so that get_signal_to_deliver() would fill one, signal_delivered(), handle_signal() and probably setup...frame() - take one).

Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.
