Cover letter [PATCH v2 0/2] Fix arm64 CONFIG_CMDLINE handling and remove CMDLINE_EXTEND

Hi again,

This is version two of the series I previously posted here:

	https://lore.kernel.org/r/[email protected]

The main change since v1 is that, rather than "fix" the FDT code to follow the documented behaviour for CMDLINE_EXTEND, I've opted to remove the thing entirely for arm64 while a less ambiguous and generic replacement is developed, probably based on either [1] or [2].

I've left the first-patch as-is so that it's easier to incorporate whatever ends up replacing CMDLINE_EXTEND in future.

Cheers,

Will
