[PATCH 0/2] zstd: Update to upstream v1.5.2

[Nick Terrell]

From: Nick Terrell <terrelln@xxxxxx>

This series first prepares the kernel's zstd for the update and then updates to
upstream zstd v1.5.2. I've separated the first patch out because it is a change
for the kernel build system, and I want to make sure it can be separately
reviewed.

The latest upstream release is v1.5.2, and I am targeting this patch for the v6.2
kernel. We will be working on a new upstream release later this year. If it is
ready by the team the v6.2 merge window rolls around, I will add another update
patch to this series.

I will be merging this into my `zstd-next` branch [0] which gets pulled into
`linux-next` for testing. So this patch series will also be available here:

Best,
