efi_lookup_mapped_addr is a handy helper function for translating
a physical address to the corresponding virtual one by scanning
through memmap.map.
This patch breaks it out into a new file for use elsewhere.

Since the efi_set_virtual_address_map call has strict init ordering
requirements, add an explicit hook in the required place.

This patch implements basic support for UEFI runtime services in the
ARM architecture - a requirement for using efibootmgr to read and update
the system boot configuration.
It also locates any presented SMBIOS configuration table and stores it
for potential later use by DMI.

In systems based on [U]EFI-conformant firmware, runtime services provide
a standardised way for the kernel to update firmware environment variables.
This is used for example by efibootmgr to update which image should be
loaded on next boot.
This patchset implements basic support for UEFI runtime s

This patch adds support for early_ioremap, based on the existing
mechanism in x86. Up to 7 regions of up to 128KB each can be
temporarily mapped in before paging_init, regardless of later highmem
status.

x86 and ia64 have the early_ioremap()/early_iounmap() functions, which are
useful for supporting things like UEFI, ACPI and SMBIOS, where configuration
tables need to be parsed before proper memory management is available,
regardless of highmem status.

Hmmm, isn't that curious! I've not really looked that this change
before, which is my mistake for accepting it, but you're right, Buffer
is not defined.
