x86: Make E820_X_MAX unconditionally larger than E820MAX It's really not necessary to limit E820_X_MAX to 128 in the non-EFI case. This commit drops E820_X_MAX's dependency on CONFIG_EFI, so that E820_X_MAX is always at least slightly larger than E820MAX. The real motivation behind this is actually to prevent some issues in the Xen kernel, where the XENMEM_machine_memory_map hypercall can produce an e820 map larger than 128 entries, even on systems where the original e820 table was quite a bit smaller than that, depending on how many IOAPICs are installed on the system.
