2008-07-10x86: remove duplicate call to use_tsc_delayGlauber Costa
Integration generated a duplicate call to use_tsc_delay. Particularly, the one that is done before we check for general tsc usability seems wrong. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-07-10x86, VisWS: turn into generic arch, flip over VISWS to generic archIngo Molnar
this is the big move: flip over VISWS to generic arch support. From this commit on CONFIG_X86_VISWS is just another (default-disabled) option that turns on certain quirks - no other complications. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-07-10x86, VisWS: turn into generic arch, add early quirks to default architecturesIngo Molnar
add early quirk support to the generic architecture code. this allows VISWS to be supported by the generic code and allows us to remove the VISWS subarch. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-10x86, VisWS: turn into generic arch, add NR_IRQS quirkIngo Molnar
NR_IRQS: let VISWS be just a sub-case of the generic code. This can create a somewhat larger irq_desc[] array if NR_CPUS is high but that should not worry VisWS which has 4 CPUs at most. Signed-off-by: Ingo Molnar <mingo@elte.hu>

update asm-x86/mach-visws/mach_apicdef.h to the generic version. This should work fine as VISWS has a standard local APIC and thus its mach_apicdef.h copy is just an ancient version of the generic code. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-07-10x86, VisWS: turn into generic arch, make VisWS boot on a regular PCIngo Molnar
first step: make the VISWS subarch boot on a regular PC. We take various shortcuts for that. We copy the generic arch setup file over into the VISWS setup file. This is the only step that is not expected to boot on a real VISWS. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-07-10ocfs2: Fix flags in ocfs2_file_lockMark Fasheh
The stack-glue merge changed the way we use flags in dlmglue in that we now use the fs/dlm equivalents. Unfortunately, a merge error left the new flock code only partially updated. This took a while to show up though, because the lock level constants are actually identical between o2dlm and fs/dlm. The *_CONVERT and *_NOQUEUE flags have different values though, which is eventually causing a crash in flags_to_o2dlm(). Signed-off-by: Mark Fasheh <mfasheh@suse.com>

2008-07-10x86: I/O APIC: Add a 64-bit variation of replace_pin_at_irq()Maciej W. Rozycki
When an interrupt is rerouted to a different I/O APIC pin the relevant entry of the irq_2_pin list should get updated accordingly so that operations are performed on the correct redirection entry. This is already done by the 32-bit variation of the code and here is a complementing 64-bit implementation. Should make someone's decision less tough when merging the two. ;) Signed-off-by: Maciej W.

2008-07-10x86, AMD IOMMU: clean up Kconfig entryFUJITA Tomonori

2008-07-10sched: fix cpu hotplugDmitry Adamushko
I think we may have a race between try_to_wake_up() and migrate_live_tasks() -> move_task_off_dead_cpu() when the later one may end up looping endlessly. Interrupts are enabled on other CPUs when migration_call(CPU_DEAD, ...) is called so we may get a race between try_to_wake_up() and migrate_live_tasks() -> move_task_off_dead_cpu(). The former one may push a task out of a dead CPU causing the later one to loop endlessly. Heiko Carstens observed: | That's exactly what explains a dump I got yesterday.
