2008-04-25xen: import arch generic part of xencommIsaku Yamahata4-0/+351
On xen/ia64 and xen/powerpc hypercall arguments are passed by pseudo physical address (guest physical address) so that it's necessary to convert from virtual address into pseudo physical address. The frame work is called xencomm. Import arch generic part of xencomm.

2008-04-25xen: make grant table arch portableIsaku Yamahata4-33/+101
split out x86 specific part from grant-table.c and allow ia64/xen specific initialization. ia64/xen grant table is based on pseudo physical address (guest physical address) unlike x86/xen. On ia64 init_mm doesn't map identity straight mapped area. ia64/xen specific grant table initialization is necessary.

2008-04-25xen: replace callers of alloc_vm_area()/free_vm_area() with xen_ prefixed oneIsaku Yamahata4-4/+12
Don't use alloc_vm_area()/free_vm_area() directly, instead define xen_alloc_vm_area()/xen_free_vm_area() and use them. alloc_vm_area()/free_vm_area() are used to allocate/free area which are for grant table mapping. Xen/x86 grant table is based on virtual address so that alloc_vm_area()/free_vm_area() are suitable. On the other hand Xen/ia64 (and Xen/powerpc) grant table is based on pseudo physical address (guest physical address) so that allocation should be done differently. The original version of xenified Linux/IA64 have its own allocate_vm_area()/free_vm_area() definitions which don't allocate vm area contradictory to those names. Now vanilla Linux already has its definitions so that it's impossible to have IA64 definitions of allocate_vm_area()/free_vm_area(). Instead introduce xen_allocate_vm_area()/xen_free_vm_area() and use them.

2008-04-25x86: unify KERNEL_PGD_PTRSJeremy Fitzhardinge8-18/+17
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.

2008-04-23Fix cardbus resource allocationLinus Torvalds1-15/+15
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).
