Ingo Molnar 7410aa1ca3 x86/boot/e820: Separate the E820 ABI structures from the in-kernel structures ... Linus pointed out that relying on the compiler to pack structures with enums is fragile not just for the kernel, but for external tooling as well which might rely on our UAPI headers. So separate the two from each other: introduce 'struct boot_e820_entry', which is the boot protocol entry format. This actually simplifies the code, as e820__update_table() is now never called directly with boot protocol table entries - we can rely on append_e820_table() and do a e820__update_table() call afterwards. ( This will allow further simplifications of __e820__update_table(), but that will be done in a separate patch. ) This change also has the side effect of not modifying the bootparams structure anymore - which might be useful for debugging. In theory we could even constify the boot_params structure - at least from the E820 code's point of view. Remove the uapi/asm/e820/types.h file, as it's not used anymore - all kernel side E820 types are defined in asm/e820/types.h.
