[PATCH] crypto: ccp: Fix double add when creating new DMA command
Eliminate a double-add by creating a new list to manage
command descriptors when created; move the descriptor to
the pending list when the command is submitted. This

[PATCH v6 0/5] Update LZ4 compressor module
This patchset is for updating the LZ4 compression module to a version based on LZ4 v1.7.3 allowing to use the fast compression algorithm aka LZ4 fast which provides an "acceleration" parameter as a tradeoff between high compression ratio and high compression speed. We want to use LZ4 fast in order to support compression in lustre and (mostly, based on that) investigate data reduction techniques in behalf of storage systems. Also, it will be useful for other users of LZ4 compression, as with LZ4 fast it is possible to enable applications to use fast and/or high compression depending on the usecase. For instance, ZRAM is offering a LZ4 backend and could benefit from an updated LZ4 in the kernel.

[PATCH] crypto: ccp: Fix DMA operations when IOMMU is enabled
An I/O page fault occurs when the IOMMU is enabled on a
system that supports the v5 CCP. DMA operations use a
Request ID value that does not match what is expected by
the IOMMU, resulting in the I/O page fault. Setting the
Request ID value to 0 corrects this issue.

Yes, the .arch_extension directive isn't universally supported by AArch64
gas so we can't rely on it unconditionally. The best bet is to check for
the support and, if it's not present, then disable whatever feature relies
on it. See the lseinstr variable in Makefile.

What do you mean 'detect'? Could you describe the failure in more detail please?

Will should confirm, but I think this is a recent feature in GAS for
AArch64, so this may break older toolchains as well.
