Subject: [PATCH v3 3/5] x86: Call efi_memblock_x86_reserve_range() on native EFI platform only
Date: Tue, 25 Mar 2014 20:57:54 +0000 [thread overview]
Message-ID: <1395781076-12000-4-git-send-email-daniel.kiper@oracle.com> (raw)
In-Reply-To: <1395781076-12000-1-git-send-email-daniel.kiper@oracle.com>
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.
