Introduce EFI_DIRECT flag. If it is set this means that Linux
Kernel has direct access to EFI infrastructure. If not then
kernel runs on EFI platform but it has not direct control
on EFI stuff. This functionality is used in Xen dom0.

Export arch_tables variable. Xen init function calls efi_config_init()
which takes it as an argument.
Additionally, put __initdata in place suggested by include/linux/init.h.

Hi,
Here is a short summary of our discussion. It looks
that we have two choices right now:
- chainloader,
- multiboot2 protocol.
chainloader solution could be implemented quite easily. Some code should be
added for command line parsing. However, all arguments for Xen itself and
modules must
or launch.

Hi,
During work on multiboot2 protocol support for Xen it was discovered
that memory map passed via relevant tag could not represent wide range
of memory types available on EFI platforms. Additionally, GRUB2
implementation calls ExitBootServices() on them just before jumping
into loaded image. In
