2008-04-24xen: support sysenter/sysexit if hypervisor doesJeremy Fitzhardinge
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.

2008-04-24x86: unify KERNEL_PGD_PTRSJeremy Fitzhardinge
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.

2008-04-22Fix cardbus resource allocationLinus Torvalds
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).
