The patch titled
     Subject: dm-crypt: use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN
has been added to the -mm mm-unstable branch.  Its filename is
     dm-crypt-use-arch_dma_minalign-instead-of-arch_kmalloc_minalign.patch

This patch will shortly appear at

Subject: dm-crypt: use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN
Date: Mon, 12 Jun 2023 16:31:53 +0100

ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA
operations while ARCH_KMALLOC_MINALIGN is the minimum kmalloc() objects
alignment.
