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. Signed-off-by:

No functional change, just identify the device nicely: -IOC: Unknown (103c:12ec) 0.1 HPA 0xf8020002000 IOVA space 1024Mb at 0x40000000 +IOC: sx2000 0.1 HPA 0xf8020002000 IOVA space 1024Mb at 0x40000000 We used to create fake PCI devices for these chips, but we no longer do that. So I don't think there's any reason to touch pci_ids.h now. Signed-off-by:

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:

Don't auto-configure yenta sockets for PCMCIA devices if it is connected to the root PCI bus on the x86 or x86_64 architectures. Previously, this was handled by the "ioport_resource"/"iomem_resource" check a few lines below, but with the new ACPI-based resource handling this doesn't catch all cases any longer. pci-yenta-cardbus-fix.patch and this patch should solve the initialization time trouble. However, the ACPI-based PCI resource handling is badly broken, IMHO: - many resources of devices don't show up in the resource trees ( /proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but also possibly other subsystems (ISA, PnP, ...) do not know which resources it cannot use. - verify_root_windows() should fail if there are no iomem _or_ ioport resources, not only if there are no iomem _and_ ioport resources.

The PCMCIA card services layer is never setting the i/o map attributes when SS_CAP_STATIC_MAP is specified. Net result, sockets' set_io_map() calls always see requests with most flags clear, meaning 8 bit access. For hardware that always autosizes, that won't matter; and all current STATIC_MAP drivers ignore those attributes. A new driver (for at91rm9200) suffers badly from this, since this forces everything into 8 bit mode and that breaks both (a) cards requiring 16 bit access, and (b) ide-cs; but of course 8-bit cards work OK (as does accessing card attributes). So this patch arranges to pass the attributes down, matching the behavior for non-static mappings (using the first/only I/O window). Signed-off-by:

- properly bail out in set_cis_map if call to socket driver's set_mem_map failed - don't abort do_mem_probe cycle if one entry failed (!CONFIG_PCMCIA_PROBE) - don't do iomem probing in chunks larger than 0x800000 (1 << 23) as yenta_socket and vrc4173_cardu.c fail to set_mem_map for windows equal to or larger than (1 << 24).

Add some information useful for PCMCIA device driver authors to Documentation/pcmcia/, and reference it in dmesg in case of hash mismatches. Also add a reference to pcmciautils to Documentation/Changes. With recent changes, you don't need to concern yourself with pcmcia-cs even if you have PCMCIA hardware, so the example above the list needed to be adapted as well. Signed-off-by:

Catch up with some PCMCIA API changes: - Docs say that as of 2.6.11 the PCMCIA IRQInfo2 field is ignored, but it's not yet removed from the API; stop using it anyway. - As of 2.6.13 PCMCIA finally hotplugs and does driver binding without "cardmgr"; add a MODULE_DEVICE_TABLE to support this.
