2007-04-27[MIPS] Change PCI host bridge setup/resourcesThomas Bogendoerfer
PCI host bridge setup for SNI RM machines with PCI is quite broken, now that Linux does it's resource setup own its own. It will use IO addresses, which are needed by the EISA config detection and assigns PCI memory addresses, which overlap with ISA legacy addresses (video ram). Below is a patch, which changes the way how the PCI memory addresses are used and sets the minimum IO address to give enough IO space for 8 EISA slots). This patch needs the other PCI resource change, I've posted. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-04-27[MIPS] Register PCI host bridge resource earlierThomas Bogendoerfer
PCI based SNI RM machines have their EISA bus behind an Intel PCI/EISA bridge. So the PCI IO range must start at 0x0000. Changing that will break the PCI bus, because i8259.c already has registered it's IO addresses before the PCI bus gets initialized. Below is a patch, which will register the PCI host bridge resources inside register_pci_controller(). It also changes i8259.c to use insert_region(), because request_resource() will fail, if the IO space of the PIT hanging of the PCI host bridge (maybe passing the resource parent to init_i8259_irqs() is a cleaner fix for that).

2007-04-20[MIPS] Fix BUG(), BUG_ON() handlingAtsushi Nemoto
With commit 63dc68a8cf60cb110b147dab1704d990808b39e2, kernel can not handle BUG() and BUG_ON() properly since get_user() returns false for kernel code. Use __get_user() to skip unnecessary access_ok(). This patch also make BRK_BUG code encoded in the TNE instruction.

2007-04-20[MIPS] Retry {save,restore}_fp_context if failed in atomic context.Atsushi Nemoto
The save_fp_context()/restore_fp_context() might sleep on accessing user stack and therefore might lose FPU ownership in middle of them. If these function failed due to "in_atomic" test in do_page_fault, touch the sigcontext area in non-atomic context and retry these save/restore operation. This is a replacement of a (broken) fix which was titled "Allow CpU exception in kernel partially".

local_irq_restore -> raw_local_irq_restore -> irq_restore_epilog -> smtc_ipi_replay -> smtc_ipi_dq -> spin_unlock_irqrestore -> _spin_unlock_irqrestore -> local_irq_restore The recursion does abort when there is no more IPI queued for a CPU, so this isn't usually fatal which is why we got away with this for so long until this was discovered by code inspection.
