| * microblaze: Remove __ARCH_WANT_INTERRUPTS_ON_CTXSW usagePeter Zijlstra2011-10-142-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As far as I can tell the only reason microblaze has __ARCH_WANT_INTERRUPTS_ON_CTXSW is because it initializes new task state with interrupts enabled so that on switch_to() interrupts get enabled. So change copy_thread() to clear MSR_IE instead of set it, this will ensure switch_to() will always keep IRQs disabled. The scheduler will disable IRQs when taking rq->lock in schedule() and enable IRQs in finish_lock_switch() after its done its magic. This leaves ARM the only __ARCH_WANT_INTERRUPTS_ON_CTXSW user.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Register early console as standard console 2. Enable CON_BOOT console flag to ensure auto-unregistering by the kernel 3. remap_early_printk function remap physical console baseaddr to virtual space Usage specific function for console remap is done after memory initialization with IRQ turn off that's why there is not necessary to protect it. The reason for remapping is that the kernel use TLB 63 for 1:1 address mapping to be able to use console in very early boot-up phase. But allocating one TLB just for console caused performance degression that's why ioremaps create new mapping and TLB 63 is automatically released and ready to use.

| * microblaze: Fix unaligned value saving to the stack for system with MMUMichal Simek2011-07-251-28/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several registers weren't saved correctly to the stack. Unaligned expection for system with MMU stores value in ex_tmp_data_loc_X address which is load to registers r3. The next step is to move this value from r3 to a destination register which caused unaligned exception. For several registers this value was directly moved to the register. For example for r28: by "or r28, r0, r3" but register r28 was rewritten when kernel returns from exception handler by value saved on stack. This patch changed r3 saving to the correct address on the stack. For example for r28: by "swi r3, r1, 4 * 28" When kernel returns from the exception handler, correct value is restored.

| * microblaze/irqs: Do not trace arch_local_{*,irq_*} functionsSteven Rostedt2011-07-251-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Do not trace arch_local_save_flags(), arch_local_irq_*() and friends. Although they are marked inline, gcc may still make a function out of them and add it to the pool of functions that are traced by the function tracer. This can cause undesirable results (kernel panic, triple faults, etc). Add the notrace notation to prevent them from ever being traced.

* | pci/of: Match PCI devices to OF nodes dynamicallyBenjamin Herrenschmidt2011-06-083-55/+14
|/ | | | | | | | | | | | | | | | | | | | | | | | powerpc has two different ways of matching PCI devices to their corresponding OF node (if any) for historical reasons. The ppc64 one does a scan looking for matching bus/dev/fn, while the ppc32 one does a scan looking only for matching dev/fn on each level in order to be agnostic to busses being renumbered (which Linux does on some platforms). This removes both and instead moves the matching code to the PCI core itself. It's the most logical place to do it: when a pci_dev is created, we know the parent and thus can do a single level scan for the matching device_node (if any). The benefit is that all archs now get the matching for free. There's one hook the arch might want to provide to match a PHB bus to its device node. A default weak implementation is provided that looks for the parent device device node, but it's not entirely reliable on powerpc for various reasons so powerpc provides its own.
