SRU Vivid - Backport ESRT support

[Colin Ian King]

I'm not seeing and SRU justification or test case for this SRU.

Has this been tested check if the newly exposed interfaces work OK?

Patches:

efi: Rename efi_guid_unparse to efi_guid_to_str
	- minor function naming, ACK
Add a "debug" option to the efi= cmdline
	- extra debug, ACK
efi: efivar_create_sysfs_entry() should return negative error codes
	- fix error return style, ACK
efi: Add esrt support
	- extra ESRT functionality, clean cherry pick, ACK
x86, doc: Remove cmdline_size from list of fields to be filled in for
EFI handover
	- trivial documentation change, ACK
efi/esrt: Fix some compiler warnings
	- looks sane, ACK
efi: dmi: List SMBIOS3 table before SMBIOS table
	- this does change the entries to /sys/firmware/efi/systab, apparently
dmidecode does not support SMBIOS 3.0 (nor does fwts), so SMBIOS3
enabled f/w with this interface change may make some userland tools get
confused.  I think I may need to fix fwts for this.
	- ACK (with comments)

efi: Add 'systab' information to Documentation/ABI
	- trivial documentation change, ACK


All clean cherry picks or trivial backports, so looks OK to me.
