The integrity target relies on skcipher for encryption/decryption, but
certain kernel configurations may not enable CRYPTO_SKCIPHER, leading to
compilation errors due to unresolved symbols. Explicitly select
CRYPTO_SKCIPHER for DM_INTEGRITY, since it is unconditionally dependent
on it.

The MSM SDHCI driver always set the "actual_clock" field to 0. It had
a comment about it not being needed because we weren't using the

Ok, from looking at the patch (not applying it and looking at the end
result), I think the locking - at least for the filemap_map_pages()
case - is a lot easier to understand.
So you seem to have fixed

The local variable 'cpumask_t mask' is in the stack memory, and its address
is assigned to 'desc->affinity' in 'irq_set_affinity_hint()'.
But the memory area where this variable is located is at risk of being
modified.

They don't have a memory mapped interface and thus are not

this may be true in practice, but it's not architecturally reliable. In
