Subject: [PATCH 3/4] efi: ia64: use common code for (U)EFI configuration scanning
This patch makes ia64 use the new common code for configuration
table scanning. It also removes the local definition of the global
"efi" data structure.
Introduces an early_memremap() alias for early_ioremap(), which
should be fine given that early_ioremap() parses the memory map for
determining type of mapping anyway.
