[PATCH v2 0/2] Use __u128 in arm64 UAPI headers

[Will Deacon]

Hi folks,

This is version two of the patch I previously sent here:

  https://lore.kernel.org/r/20260619130835.5678-1-will@xxxxxxxxxx

I even briefly queued that version up, but it exploded spectacularly
when building the kselftests for arm64 [1] [2]. So the only change since
v1 is the addition of a preliminary patch that adds the '__u128' typedef
to the private copy of linux/types.h used by the tools/ directory.

I plan to take this all via the arm64 tree unless anybody objects.

Cheers,

Will
