2008-03-27x86: prefetch fix #2Ingo Molnar
Linus noticed a second bug and an uncleanliness: - we'd return on any instruction fetch fault - we'd use both the value of 16 and the PF_INSTR symbol which are the same and make no sense the cleanup nicely unifies this piece of logic. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-03-27xen: fix UP setup of shared_infoJeremy Fitzhardinge
We need to set up the shared_info pointer once we've mapped the real shared_info into its fixmap slot. That needs to happen once the general pagetable setup has been done. Previously, the UP shared_info was set up one in xen_start_kernel, but that was left pointing to the dummy shared info. Unfortunately there's no really good place to do a later setup of the shared_info in UP, so just do it once the pagetable setup has been done.

2008-03-27xen: fix RMW when unmasking eventsJeremy Fitzhardinge
xen_irq_enable_direct and xen_sysexit were using "andw $0x00ff, XEN_vcpu_info_pending(vcpu)" to unmask events and test for pending ones in one instuction. Unfortunately, the pending flag must be modified with a locked operation since it can be set by another CPU, and the unlocked form of this operation was causing the pending flag to get lost, allowing the processor to return to usermode with pending events and ultimately deadlock. The simple fix would be to make it a locked operation, but that's rather costly and unnecessary. The fix here is to split the mask-clearing and pending-testing into two instructions; the interrupt window between them is of no concern because either way pending or new events will be processed. This should fix lingering bugs in using direct vcpu structure access too.

2008-03-26x86: fix performance drop for glxSuresh Siddha
fix the 3D performance drop reported at: http://bugzilla.kernel.org/show_bug.cgi?id=10328 fb drivers are using ioremap()/ioremap_nocache(), followed by mtrr_add with WC attribute. Recent changes in page attribute code made both ioremap()/ioremap_nocache() mappings as UC (instead of previous UC-). This breaks the graphics performance, as the effective memory type is UC instead of expected WC. The correct way to fix this is to add ioremap_wc() (which uses UC- in the absence of PAT kernel support and WC with PAT) and change all the fb drivers to use this new ioremap_wc() API. We can take this correct and longer route for post 2.6.25. For now, revert back to the UC- behavior for ioremap/ioremap_nocache.

2008-03-25KVM: VMX: Restore tss even on x86_64Avi Kivity
The vmx hardware state restore restores the tss selector and base address, but not its length. Usually, this does not matter since most of the tss contents is within the default length of 0x67. However, if a process is using ioperm() to grant itself I/O port permissions, an additional bitmap within the tss, but outside the default length is consulted. The effect is that the process will receive a SIGSEGV instead of transparently accessing the port. Fix by restoring the tss length. Note that i386 had this working already. Closes bugzilla 10246.

2008-03-24[SPARC64]: Make save_stack_trace() more efficient.David S. Miller
Doing a 'flushw' every stack trace capture creates so much overhead that it makes lockdep next to unusable. We only care about the frame pointer chain and the function caller program counters, so flush those by hand to the stack frame. This is significantly more efficient than a 'flushw' because: 1) We only save 16 bytes per active register window to the stack. 2) This doesn't push the entire register window context of the current call chain out of the cpu, forcing register window fill traps as we return back down. Note that we can't use 'restore' and 'save' instructions to move around the register windows because that wouldn't work on Niagara processors. They optimize 'save' into a new register window by simply clearing out the registers instead of pulling them in from the on-chip register window backing store. Based upon a report by Tom Callaway.

It appears that 64-bit PCI resources cannot possibly ever have worked on x86-32 even when the RESOURCES_64BIT config option was set, because any driver that tried to [pci_]ioremap() the resource would have been unable to do so because the high 32 bits would have been silently dropped on the floor by the ioremap() routines that only used "unsigned long". Change them to use "resource_size_t" instead, which properly encodes the whole 64-bit resource data if RESOURCES_64BIT is enabled. Acked-by: H.

2008-03-24[POWERPC] Fix Oops with TQM5200 on TQM5200Anatolij Gustschin
The "bestcomm-core" driver defines its of_match table as follows static struct of_device_id mpc52xx_bcom_of_match[] = { { .type = "dma-controller", .compatible = "fsl,mpc5200-bestcomm", }, { .type = "dma-controller", .compatible = "mpc5200-bestcomm", }, {}, }; so while registering the driver, the driver's probe function won't be called, because the device tree node doesn't have a device_type property. Thus the driver's bcom_engine structure won't be allocated. Referencing this structure later causes observed Oops. Checking bcom_eng pointer for NULL before referencing data pointed by it prevents oopsing, but fec driver still doesn't work (because of the lost bestcomm match and resulted task allocation failure). Actually the compatible property exists and should match and so the fec driver should work. This removes .type = "dma-controller" from the bestcomm driver's mpc52xx_bcom_of_match table to solve the problem.

2008-03-24[POWERPC] Don't use 64k pages for ioremap on pSeriesPaul Mackerras
On pSeries, the hypervisor doesn't let us map in the eHEA ethernet adapter using 64k pages, and thus the ehea driver will fail if 64k pages are configured. This works around the problem by always using 4k pages for ioremap on pSeries (but not on other platforms). A better fix would be to check whether the partition could ever have an eHEA adapter, and only force 4k pages if it could, but this will do for 2.6.25.
