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

[Will Deacon]

Hi again,

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

	https://lore.kernel.org/r/20210225125921.13147-1-will@kernel.org

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
