The data should say:
meson: disable octeontx for buggy compilers on arm64
meson: change default cache line size for cortex-a72
net/mlx: fix library search in meson build
meson: add Mellanox BlueField cross-compile config
build: add option for armv8 crypto extension
mk: disable armv8 crypto extension for Mellanox BlueField

If those are fixes then it needs to back ported to stable tree.
What bothers to me as maintainer that it painting a different picture that
arm64 still has build issues for meson. It is not the case.
So it its good to say what the actual content is, Let me ask you way around,
If it is just informational not going to merged then why to change to something
more appropriate.

I don't have any strong opinion keep the cover letter or not? You can decide.
