[PATCH 0/5] ia64 ioremap, DMI, EFI system table

OK, here's a set of patches to (hopefully) clean up this area
a bit:

1 Simplify efi_mem_attribute_range() so I can use it both for
/dev/mem validation and ioremap() attribute checking.

2 Make ia64 ioremap() check memory attributes, so it works for
plain memory that only supports write-back access, as well as
for MMIO space that only supports uncacheable access.

3 DMI ioremaps too much space, which makes it fail on machines
where the SMBIOS table is near the end of a memory region.

4 Keep EFI table addresses as physical, not virtual. The SMBIOS
address was physical on x86 but virtual on ia64, which broke
dmi_scan_machine().

5 Use smarter ioremap() implementation to remove some cruft in
acpi_os_{read,write,map}_memory(). This one's just an optional
cleanup; I don't think it fixes any bugs.
