* | powerpc/ps3: Fix SMP lockdep boot warningGeoff Levand2011-11-161-32/+32

* | powerpc/ps3: Fix lost SMP IPIsGeoff Levand2011-11-163-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes the PS3 bootup hang introduced in 3.0-rc1 by: commit 317f394160e9beb97d19a84c39b7e5eb3d7815a sched: Move the second half of ttwu() to the remote cpu Move the PS3's LV1 EOI call lv1_end_of_interrupt_ext() from ps3_chip_eoi() to ps3_get_irq() for IPI messages. If lv1_send_event_locally() is called between a previous call to lv1_send_event_locally() and the coresponding call to lv1_end_of_interrupt_ext() the second event will not be delivered to the target cpu. The PS3's SMP IPIs are implemented using lv1_send_event_locally(), so if two IPI messages of the same type are sent to the same target in a relatively short period of time the second IPI event can become lost when lv1_end_of_interrupt_ext() is called from ps3_chip_eoi().

* | powerpc/trace: Add a dummy stack frame for trace_hardirqs_offKevin Hao2011-11-161-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The trace_hardirqs_off will use CALLER_ADDR0 and CALLER_ADDR1. If an exception occurs in user mode, there is only one stack frame on the stack and accessing the CALLER_ADDR1 will causes the following call trace. So we create a dummy stack frame to make trace_hardirqs_off happy.

* | powerpc: Copy down exception vectors after feature fixupsAnton Blanchard2011-11-166-2/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | kdump fails because we try to execute an HV only instruction. Feature fixups are being applied after we copy the exception vectors down to 0 so they miss out on any updates. We have always had this issue but it only became critical in v3.0 when we added CFAR support (breaks POWER5) and v3.1 when we added POWERNV (breaks everyone).

* | powerpc: panic if we can't instantiate RTASAnton Blanchard2011-11-161-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I had to debug a strange situation where all manner of things were failing. SMT threads, storage and network were all completely broken. The root cause was we couldn't find enough memory to instantiate RTAS - this was a network install so the initrd was huge. Instead of limping along and failing in mysterious ways we should just panic up front if RTAS exists and we can't allocate space for it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally logical and hard cpu ID are the same, however in same cases like on the P3060 they may differ. Where the logical is 0..5, the hard id goes 0,1,4..7. This can causes issues for places we utilize PIR to index into array like in debug exception handlers for finding the exception stack. Move to setting up PIR with hard_smp_processor_id fixes the issue. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
