Replacing __do_IRQ() by proper flow handler would make the irq handling path a bit simpler and faster. * use generic_handle_irq() instead of __do_IRQ(). * use handle_level_irq for obvious level-type irq chips. * use handle_percpu_irq for irqs marked as IRQ_PER_CPU. * setup .eoi routine for irq chips possibly used with handle_percpu_irq.

Functions for these method are already exist in most case. * Do not initialize .startup, .shutdown, .enable, .disable fields if default routines provided by irq_chip_set_defaults() were suitable. * Remove redundant irq_desc initializations. * Remove unnecessary local_irq_save/local_irq_restore, spin_lock. With this cleanup, it would be easy to switch to slightly lightwait irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ(). Though whole this patch is quite large, changes in each irq_chip are not quite simple. Please review and test on your platform. Thanks.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __pa() was used by virt_to_page() and virt_addr_valid(). These latter are used when kernel is initialised so __pa() is not appropriate, we use virt_to_phys() instead. Futhermore __pa() is going to take care of CKSEG0/XKPHYS address mix for 64 bit kernels. This makes __pa() more complex than virt_to_phys() and this extra work is not needed by virt_to_page() and virt_addr_valid(). Eventually it consolidates virt_to_phys() prototype by making its argument 'const'. this avoids some warnings that was due to some virt_to_page() usages which pass const pointer.

In this phase, when running with an ACPI capable PROM, the DSDT will define the root busses and all SN nodes (SGIHUB, SGITIO). An ACPI bus driver will be registered for the node devices, with the acpi_pci_root_driver being used for the root busses. An ACPI vendor descriptor is now used to pass platform specific information for both nodes and busses, eliminating the need for the current SAL calls. Also, with ACPI support, SN fixup code is no longer needed to initiate the PCI bus scans, as the acpi_pci_root_driver does that. However, to maintain backward compatibility with non-ACPI capable PROMs, none of the current 'fixup' code can been deleted, though much restructuring has been done. For example, the bulk of the code in io_common.c is relocated code that is now common regardless of what PROM is running, while io_acpi_init.c and io_init.c contain routines specific to an ACPI or non ACPI capable PROM respectively. A new pci bus fixup platform vector has been created to provide a hook for invoking platform specific bus fixup from pcibios_fixup_bus(). The size of io_space[] has been increased to support systems with large IO configurations. Signed-off-by: John Keller <jpk@sgi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * | PCI: Use pci_generic_prep_mwi on sparc64Matthew Wilcox2006-12-011-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The setting of the CACHE_LINE_SIZE register in sparc64's pci initialisation code isn't quite adequate as the device may have incompatible requirements. The generic code tests for this, so switch sparc64 over to using it. Since sparc64 has different L1 cache line size and PCI cache line size, it would need to override the generic code like i386 and ia64 do. We know what the cache line size is at compile time though, so introduce a new optional constant PCI_CACHE_LINE_BYTES.

| * | PCI: Use pci_generic_prep_mwi on ia64Matthew Wilcox2006-12-011-51/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pci_generic_prep_mwi() code does everything that pcibios_prep_mwi() does on ia64. All we need to do is be sure that pci_cache_line_size is set appropriately, and we can delete pcibios_prep_mwi(). Using SMP_CACHE_BYTES as the default was wrong on uniprocessor machines as it is only 8 bytes. The default in the generic code of L1_CACHE_BYTES is at least as good.

| * | PCI: quirks: fix the festering mess that claims to handle IDE quirksAlan Cox2006-12-011-46/+0
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The number of permutations of crap we do is amazing and almost all of it has the wrong effect in 2.6. At the heart of this is the PCI SFF magic which says that compatibility mode PCI IDE controllers use ISA IRQ routing and hard coded addresses not the BAR values. The old quirks variously clears them, sets them, adjusts them and then IDE ignores the result. In order to drive all this garbage out and to do it portably we need to handle the SFF rules directly and properly. Because we know the device BAR 0-3 are not used in compatibility mode we load them with the values that are implied (and indeed which many controllers actually thoughtfully put there in this mode anyway). This removes special cases in the IDE layer and libata which now knows that bar 0/1/2/3 always contain the correct address. It means our resource allocation map is accurate from boot, not "mostly accurate" after ide is loaded, and it shoots lots of code. There is also lots more code and magic constant knowledge to shoot once this is in and settled. Been in my test tree for a while both with drivers/ide and with libata. Wants some -mm shakedown in case I've missed something dumb or there are corner cases lurking. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
