Following sets of patches add EFI/UEFI (Unified Extensible Firmware Interface) runtime services support to x86_64 architecture. The patches have been tested against 2.6.24-rc1 kernel on Intel platforms with EFI1.10 and UEFI2.0 firmware.
v4: - EFI boot parameters are extended for 64-bit EFI in a 32-bit EFI compatible way. - Add EFI runtime services document. v3: - Remove E820_RUNTIME_CODE, the EFI memory map is used to deal with EFI runtime code area. - The method used to make EFI runtime code area executable is change: a. Before page allocation is usable, the PMD of direct mapping is changed temporarily before and after each EFI call. b. After page allocation is usable, change_page_attr_addr is used to change corresponding page attribute. - Use fixmap to map EFI memory mapped IO memory area to make kexec workable. - Add a kernel command line option "noefi" to make it possible to turn off EFI runtime services support. - Function pointers are used for EFI time runtime service. - EFI reboot runtime service is embedded into the framework of reboot_type. - A kernel command line option "noefi_time" is added to make it possible to fall back to CMOS based implementation. v2: - The EFI callwrapper is re-implemented in assembler.
