Remove x86 dependency in drivers/xen/events.c for ia64/xen support introducing include/asm/xen/events.h. Introduce xen_irqs_disabled() to hide regs->flags Introduce xen_do_IRQ() to hide regs->orig_ax. make enum ipi_vector definition arch specific. ia64/xen needs four vectors. Add one rmb() because on ia64 xchg() isn't barrier. Signed-off-by:

move arch/x86/xen/events.c undedr drivers/xen to share codes with x86 and ia64. And minor adjustment to compile. ia64/xen also uses events.c Signed-off-by:

ia64/xen also uses it too. Move it into common place so that ia64/xen can share the code. Signed-off-by:

Add xen handles realted definitions for xen vcpu which ia64/xen needs. Pointer argumsnts for ia64/xen hypercall are passed in pseudo physical address (guest physical address) so that it is required to convert guest kernel virtual address into pseudo physical address. The xen guest handle represents such arguments. Signed-off-by:

Add xen handles realted definitions for grant table which ia64/xen needs. Pointer argumsnts for ia64/xen hypercall are passed in pseudo physical address (guest physical address) so that it is required to convert guest kernel virtual address into pseudo physical address right before issuing hypercall. The xen guest handle represents such arguments. Define necessary handles and helper functions. Signed-off-by:

Add xen VIRQ numbers defined for arch specific use. ia64/xen domU uses VIRQ_ARCH_0 for virtual itc timer. Although all those constants aren't used yet by ia64 at this moment, add all arch specific VIRQ numbers. Signed-off-by:

Add xen hypercall numbers defined for arch specific use. ia64/xen domU uses __HYPERVISOR_arch_1 to manipulate paravirtualized IOSAPIC. Although all those constants aren't used yet by IA64 at this moment, add all arch specific hypercall numbers. Signed-off-by:

Use jmp rather than call for the iret fixup, so its consistent with the sysexit fixup, and it simplifies the stack (which is already complex). Signed-off-by:

Mask MCE/MCA out of cpu caps. Its harmless to leave them there, but it does prevent the kernel from starting an unnecessary thread. Signed-off-by:

If an event comes in while events are currently being processed, then just increment the counter and have the outer event loop reprocess the pending events. This prevents unbounded recursion on heavy event loads (of course massive event storms will cause infinite loops). Signed-off-by:

retrigger_dynirq() was incomplete, and didn't properly set the event to be pending again. It doesn't seem to actually get used. Signed-off-by:

Xen supports the notion of a debug interrupt which can be triggered from the console. For now this is implemented to show pending events, masks and each CPU's pending event set. Signed-off-by:

64-bit Xen supports sysenter for 32-bit guests, so support its use. (sysenter is faster than int $0x80 in 32-on-64.) sysexit is still not supported, so we fake it up using iret. Signed-off-by:

Make KERNEL_PGD_PTRS common, as previously it was only being defined for 32-bit. There are a couple of follow-on changes from this: - KERNEL_PGD_PTRS was being defined in terms of USER_PGD_PTRS. The definition of USER_PGD_PTRS doesn't really make much sense on x86-64, since it can have two different user address-space configurations. I renamed USER_PGD_PTRS to KERNEL_PGD_BOUNDARY, which is meaningful for all of 32/32, 32/64 and 64/64 process configurations. - USER_PTRS_PER_PGD was also defined and was being used for similar purposes. Converting its users to KERNEL_PGD_BOUNDARY left it completely unused, and so I removed it. Signed-off-by:

Commit 88452565 ("PCI: clean up resource alignment management") didn't set the alignment information for the cardbus window resources, causing their subsequent allocations to fail miserably with a message like yenta_cardbus 0000:15:00.0: device not available because of BAR 7 [100:1ff] collisions yenta_cardbus: probe of 0000:15:00.0 failed with error -16 or similar. This fixes it and clarifies the code a bit too (we used to have to use the insane PCI bridge alignment logic that put the alignment in the "start" field, this makes it use the slightly easier-to-understand size-based alignment, and allows us to set the resource start to zero until it gets allocated).
