Subject: [PATCH v4 0/5] Fix double allocation in swiotlb_alloc()

Hi again, folks,

This is version four of the patches which I previously posted at:

v1: https://lore.kernel.org/r/20240126151956.10014-1-will@kernel.org
v2: https://lore.kernel.org/r/20240131122543.14791-1-will@kernel.org
v3: https://lore.kernel.org/r/20240205190127.20685-1-will@kernel.org

Thanks to Petr for his Reviewed-by tag on the first three.

Changes since v3 include:

  - Use umax() instead of max() to fix a build warning if the first
    patch is applied to older kernels which warn on signedness
    mismatches.

  - Add two new patches to the end of the series to resolve some
    additional issues with NVME and 64KiB pages, reported by Nicolin.
    I've added them to this series, as the first three patches make it
    easier to fix this problem in the SWIOTLB code.

  - Add Reviewed-by tags from Petr

Cheers,

Will
