Subject: [PATCH] x86: CONFIG_EFI should select CONFIG_RELOCATABLE
Date: Thu, 9 Jun 2011 10:32:44 -0400 [thread overview]
Message-ID: <1307629964-31658-1-git-send-email-mjg@redhat.com> (raw)
EFI doesn't provide any guarantees that any given address will be free,
so the bootloader must have the freedom to position the kernel
appropriately. Make CONFIG_EFI select CONFIG_RELOCATABLE in order to
ensure that this constraint is satisfiable.

This enables the kernel to use EFI runtime services that are
available (such as the EFI variable services).
