[PATCH 6.6 0/3] arm64: Speed up boot with faster linear map creation

[Ryan Roberts]

Hi All,

This series is a backport that applies to stable kernel 6.6 (base v6.6.126), 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
