ACPICA: EFI: Add EFI interface definitions to eliminate dependency of GNU EFI
ACPICA commit 5d00e67a74542d030f0a55e7a947a020ef0d9693 This patch copies EFI interface definitions to the ACPICA code base so that the EFI utility support can be ported to other EFI implementation. Known issues: 1. MS Builds of uefi_call_wrapper() The uefi_call_wrapper() in GNU EFI is implemented in a the way to work around the ABI difference between Unix and MS. While I don't have environment to test the MS builds. In order to port the ACPICA utilities to other EFI implementation, all that need to be done is to impelement the 64-bit division support and the program entry point where the efi_main() is invoked. Code to impelement these is platform specific, and ACPICA currently choose to hide such platform specific code within the specific EFI impelementation. Lv Zheng. This patch doesn't affect Linux kernel.
