At present, if we have a kernel with a 64kB page size, and some process maps something that has to be mapped with 4kB pages (such as a cache-inhibited mapping on POWER5+, or the eHCA infiniband queue-pair pages), we change the process to use 4kB pages everywhere. This hurts the performance of HPC programs that access eHCA from userspace. With this patch, the kernel will only demote the slice(s) containing the eHCA or cache-inhibited mappings, leaving the remaining slices able to use 64kB hardware pages. This also changes the slice_get_unmapped_area code so that it is willing to place a 64k-page mapping into (or across) a 4k-page slice if there is no better alternative, i.e. if the program specified MAP_FIXED or if there is not sufficient space available in slices that are either empty or already have 64k-page mappings in them.

While working on the 36-bit physical support, I noticed that there was exactly one line of code that actually referenced the bitfields. So I got rid of them and redefined ppc_bat as a struct of 2 u32's: batu and batl. I also got rid of the previous union that held the bitfield structs and a word representation of the batu/l values. This seems like a nicer solution than adding in a bunch of new bitfields to support extended bat addressing that would never get used, and just leaving the struct as-is would have been incomplete in the face of large physical addressing.

Currently, the physical address is an unsigned long, but it should be phys_addr_t in set_bat, [v/p]_mapped_by_bat. Also, create a macro that can convert a large physical address into the correct format for programming the BAT registers.

This frees a PTE bit when using 64K pages on ppc64. This is done by getting rid of the separate _PAGE_HASHPTE bit. Instead, we just test if any of the 16 sub-page bits is set. For non-combo pages (ie. real 64K pages), we set SUB0 and the location encoding in that field.

To avoid "#ifdef CONFIG_PCI" in the drivers we should provide stubs in place of OF PCI address accessors. Without these stubs build breaks for drivers not strictly requiring PCI, for example CONFIG_FB_OF=y without CONFIG_PCI: LD .tmp_vmlinux1 drivers/built-in.o: In function `offb_map_reg': offb.c:(.text+0x6e7c): undefined reference to `of_get_pci_address' OF PCI IRQ accessors require pci_dev argument, so drivers using PCI IRQs should depend on CONFIG_PCI anyway.
