Hi All,

This series is a backport that applies to stable kernel 6.1 (base v6.1.163), for
some speed ups to enable significantly faster booting on systems with a lot of
memory. The patches were originally posted at:

  https://lore.kernel.org/linux-arm-kernel/20240412131908.433043-1-ryan.roberts@arm.com/

... and were originally merged upstream in v6.10-rc1.

I'm requesting this be merged to stable on behalf of a partner who wants to get
the benefit of this series in Debian 12.

Thanks,
Ryan

Same here, why not just use 6.12.y?

Ok, I'll take the 6.6.y patches, but for 6.1.y, people should _REALLY_
move off of it if they are using these types of systems as there are
loads of other things/fixes that they will get if they move.

thanks,
