ARM: provide improved virt_to_idmap() functionality
For kexec, we need more functionality from the IDMAP system. We need to be able to convert physical addresses to their identity mappped versions as well as virtual addresses. Convert the existing arch_virt_to_idmap() to deal with physical addresses instead. Acked-by: Santosh Shilimkar <[email protected]> Signed-off-by: Russell King <[email protected]>
