[PATCH v3 3/5] x86: Call efi_memblock_x86_reserve_range() on native EFI platform only

From: Daniel Kiper
Date: Tue Mar 25 2014 - 16:59:11 EST


Call efi_memblock_x86_reserve_range() on native EFI platform only.
This is not needed and even it should not be called on platforms
which wraps EFI infrastructure like Xen.
