Remove legacy ISA serial ports for Accent, Boca, Fourport, Hub6 and MCA from the architecture specific serial.h include. The only ports which remain in asm-*/serial.h are the platform specific entries. These should really be converted by platform maintainers to use a platform device, such as can be found in arch/arm/mach-footbridge/isa.c Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Patch from Catalin Marinas The compiler allocates r14 for the stk variable in the __asm__ directive. This is a shadowed register and gets changed when the mode is changed, causing random values in the SP register. The patch adds a clobber for the r14 register.

Anyone reporting a stuck IRQ should try these options. Its effectiveness varies we've found in the Fedora case. Quite a few systems with misdescribed IRQ routing just work when you use irqpoll. It also fixes up the VIA systems although thats now fixed with the VIA quirk (which we could just make default as its what Redmond OS does but Linus didn't like it historically). A small number of systems have jammed IRQ sources or misdescribes that cause an IRQ that we have no handler registered anywhere for. In those cases it doesn't help.

This patch is a sparse compile cleanup of shub_mmr.h using both the defconfig and the sn2_defconfig config files. The issue with this file was the missing usage of __IA64_UL_CONST wrapper. This wrapper is defined in include/asm-ia64/types.h and wraps a long constant definition with UL or with nothing depending on its usage in the kernel.

This patch greatly speeds up the handling of lfetch.fault instructions which result in NaT consumption. Due to the NaT-page mapped at address 0, this is guaranteed to happen when lfetch.fault'ing a NULL pointer. With this patch in place, we can even define prefetch()/prefetchw() as lfetch.fault without significant performance degradation. More importantly, it allows compilers to be more aggressive with using lfetch.fault on pointers that might be NULL.

Resend 2 with changes per Bjorn Helgaas comments. Changes from original: + Change globals to vga_console_iobase/vga_console_membase and make them unconditional. + Address style-related comments. Patch to extend the PCDP vga setup code to support PCI io/mem translations for the legacy vga ioport and ram spaces on architectures (e.g. altix) which need them. Summary of the changes: drivers/firmware/pcdp.c drivers/firmware/pcdp.h ----------------------- + add declaration for the spec-defined PCI interface struct (pcdp_if_pci) as well as support macros. + extend setup_vga_console() to know about pcdp_if_pci and add a couple of globals to hold the io and mem translation offsets if present. arch/ia64/kernel/setup.c ------------------------ + tweek early_console_setup() to allow multiple early console setup routines to be called. include/asm-ia64/vga.h ---------------------- + make VGA_MAP_MEM vga_console_membase aware Signed-off-by: NMark Maule <maule@sgi.com> Signed-off-by: NTony Luck <tony.luck@intel.com>

Now that we have access to the whole MCFG table, let's properly use it for all pci device accesses (as that's what it is there for, some boxes don't put all the busses into one entry.) If, for some reason, the table is incorrect, we fallback to the "old style" of mmconfig accesses, namely, we just assume the first entry in the table is the one for us, and blindly use it.

This patch is the first step in properly handling the MCFG PCI table. It defines the structures properly, and saves off the table so that the pci mmconfig code can access it. It moves the parsing of the table a little later in the boot process, but still before the information is needed. Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This is an updated version of Ben's fix-pci-mmap-on-ppc-and-ppc64.patch which is in 2.6.12-rc4-mm1. It fixes the patch to work on PPC iSeries, removes some debug printks at Ben's request, and incorporates your fix-pci-mmap-on-ppc-and-ppc64-fix.patch also. Originally from Benjamin Herrenschmidt <benh@kernel.crashing.org> This patch was discussed at length on linux-pci and so far, the last iteration of it didn't raise any comment. It's effect is a nop on architecture that don't define the new pci_resource_to_user() callback anyway. It allows architecture like ppc who put weird things inside of PCI resource structures to convert to some different value for user visible ones. It also fixes mmap'ing of IO space on those archs.

This patch adds the following new interfaces for I/O xAPIC hotplug. The implementation of these interfaces depends on each architecture. o int acpi_register_ioapic(acpi_handle handle, u64 phys_addr, u32 gsi_base); This new interface is to add a new I/O xAPIC specified by phys_addr and gsi_base pair. phys_addr is the physical address to which the I/O xAPIC is mapped and gsi_base is global system interrupt base of the I/O xAPIC. acpi_register_ioapic returns 0 on success, or negative value on error. o int acpi_unregister_ioapic(acpi_handle handle, u32 gsi_base); This new interface is to remove a I/O xAPIC specified by gsi_base. acpi_unregister_ioapic returns 0 on success, or negative value on error.

PCI scan code calls the arch specific pcibios_fixup_bus() each time it scans a new bridge. For root bridge hot-plug, the bridge and it's attached devices may not have been configured properly yet, so it's not safe to claim those resources at this time. This code goes away when we clean up the way pci resources are claimed (in pci_enable_device()), so this is only a stopgap fix.
