From 9a9943575ade643368849e2c963094ac637867e0 Mon Sep 17 00:00:00 2001 From: Mark Mason Date: Fri, 13 Apr 2007 10:32:25 -0700 Subject: [MIPS] Add missing silicon revisions for BCM112x Recent versions of the BCM112X processors aren't recognized by Linux (preventing Linux from booting on those processors).

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".

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).

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.
