When testing for the REX instruction prefix, first check for 32-bit mode because in compat mode the REX prefix is an increment instruction. Signed-off-by:

Lock sections don't work the new dwarf2 unwinder This generates slightly smaller code. It adds one more taken jump to the fast path. Cc: jbeulich@novell.com Signed-off-by: -

The pci_get_device() API decrements the reference count on the 'from' parameter when it continues searching. Therefore, take a ref count on Calgary bus when we initialize them in either translated or non-translated mode. Signed-off-by:

We were freeing the iommu_table and leaking the bitmap pages. Also rename it to calgary_free_bus, which is more accurate. Signed-off-by:

Move the tce_table_kva array, disabled bitmap and bus_to_phb array into a new per bus 'struct calgary_bus_info'. Also slightly reorganize build_tce_table and tce_table_setparms to avoid exporting bus_info to tce.c. Signed-off-by:

Move initialization of all memory end variables to as early as possible, so that dependent code doesn't need to check whether these variables have already been set. Change the range check in kunmap_atomic to actually make use of this so that the no-mapping-estabished path (under CONFIG_DEBUG_HIGHMEM) gets used only when the address is inside the lowmem area (and BUG() otherwise).

While an earlier patch already did a small step into that direction, this patch moves initialization of all memory end variables to as early as possible, so that dependent code doesn't need to check whether these variables have already been set. Also, remove a misleading (perhaps just outdated) comment, and make static a variable only used in a single file. Signed-off-by:

... instead of using a CONFIG option. The config option still controls if the resulting executable actually has unwind information. This is useful to prevent compilation errors when users select CONFIG_STACK_UNWIND on old binutils and also allows to use CFI in the future for non kernel debugging applications.

The MPS table specification says that the operating system should renumber the IO-APICs following the table as needed. However in ACPI this is not allowed or neeeded and all x86-64 systems are ACPI compliant. The code was already disabled on some systems because it caused problems there. Remove it completely now.

Bugzilla #6552 says: "In arch/i386/boot/setup.S, movw is used instead of movb for PS/2 mouse information, although it is unsigned char. This does not harm, because the jmp instruction overwritten by movw is used before executing movw, and never be used again" I've no idea if this is a real bug or how it gets fixed, so I'm submitting it for review instead of letting it die of boredom in bugzilla. Aditionally to i386, I've changed x86-64, which mirrors the same code. Credits to Yoshinori K. Okuji, who found the problem and suggested a fix. Signed-off-by:

The IO APIC code had lots of duplicated code to read/write 64bit routing entries into the IO-APIC. Factor this out int common read/write functions In a few cases the IO APIC lock is taken more often now, but this isn't a problem because it's all initialization/shutdown only slow path code. Similar to earlier x86-64 patch. Includes a fix by Jiri Slaby for a mistake that broke resume Signed-off-by: -

PIC mode is an outdated way to drive the APICs that was used on some early MP boards. It is not supported in the ACPI model. It is unlikely to be ever configured by any x86-64 system Remove it thus. Signed-off-by: -

This was an old workaround for broken MP-BIOS. The user could specify overwrites on the command line. I've never seen it being used for anything on 64bit. So get rid of it for now. Signed-off-by: -

IO-APIC or local APIC can only be disabled at runtime anyways and Kconfig has forced these options on for a long time now. The Kconfigs are kept only now for the benefit of the shared acpi boot.c code. Signed-off-by:
