Subject: [PATCH] gnu: linux-libre: Update to 5.10.1.
Date: Mon, 14 Dec 2020 21:16:11 -0500

[Message part 1 (text/plain, inline)]

This patch updates linux-libre to 5.10.1.

I tested the basics on x86_64 and i686.

There's one new kernel configuration option I wasn't sure about,
CONFIG_DMA_PERNUMA_CMA.

It's described like this: "Enable this option to get pernuma CMA areas
so that devices like ARM64 SMMU can get local memory by DMA coherent
APIs." [0]

I set it to Yes for all four architectures. What do you think? I don't
really understand what it does and if it's appropriate for a distro
kernel or not.
