* xen: definisions which ia64 needsIsaku Yamahata2008-04-24
| | | | | | | | | | | | 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.

* xen: jump to iret fixupJeremy Fitzhardinge2008-04-24
| | | | | | | | | | 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).

* xen: no need for domU to worry about MCE/MCAJeremy Fitzhardinge2008-04-24
| | | | | | | | | Mask MCE/MCA out of cpu caps. Its harmless to leave them there, but it does prevent the kernel from starting an unnecessary thread.

* xen: short-cut for recursive event handlingJeremy Fitzhardinge2008-04-24
| | | | | | | | | | | 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).

* xen: implement a debug-interrupt handlerJeremy Fitzhardinge2008-04-24
| | | | | | | | | | 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.

* xen: support sysenter/sysexit if hypervisor doesJeremy Fitzhardinge2008-04-24
| | | | | | | | | | | 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.

* x86: unify KERNEL_PGD_PTRSJeremy Fitzhardinge2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | The only reason to have separated __...() for those was to keep them inlined for local users in exit.c.

* | Fix cardbus resource allocationLinus Torvalds2008-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 884525655d07fdee9245716b998ecdc45cdd8007 ("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).
