Hi Alex,

Varargs differ between sysv and ms abi. On x86_64 we have to follow the ms abi though, so we also need to make sure we use x86_64 varargs helpers.
This patch introduces generic efi vararg helpers that adhere to the respective EFI ABI. That way we can deal with them properly from efi loader code and properly interpret variable arguments.
This fixes the InstallMultipleProtocolInterfaces tests in the efi selftests on x86_64 for me.

Thanks, applied to efi-next
I applied this patch on my x86 tree and tested there, but qemu-x86_64_defconfig still fails when 'bootefi selftest'. Anything I am missing?
Where does it fail? There is basically this pitfall and setjmp/longjmp that can easily go wrong.
