Don't worry too much about the commit message. The only thing to change
is that the commit title should begin with 'gnu', which is how we denote
that the change touches the software distribution portion of guix.git,
as compared to 'guix', 'doc', 'build', etc. But I would normally handle
that without mentioning it to the patch submitter.

Grepping for 'HSA_AMD' in guix.git:

$ git grep HSA_AMD
gnu/packages/aux-files/linux-libre/5.10-arm64.conf:# CONFIG_HSA_AMD is not set
gnu/packages/aux-files/linux-libre/5.10-x86_64.conf:# CONFIG_HSA_AMD is not set
gnu/packages/aux-files/linux-libre/5.15-arm64.conf:# CONFIG_HSA_AMD is not set
gnu/packages/aux-files/linux-libre/5.15-x86_64.conf:# CONFIG_HSA_AMD is not set
gnu/packages/aux-files/linux-libre/5.18-arm64.conf:# CONFIG_HSA_AMD is not set
gnu/packages/aux-files/linux-libre/5.18-x86_64.conf:# CONFIG_HSA_AMD is not set
gnu/packages/aux-files/linux-libre/5.4-arm64.conf:# CONFIG_HSA_AMD is not set
gnu/packages/aux-files/linux-libre/5.4-x86_64.conf:# CONFIG_HSA_AMD is not set

Yes, there is actually some 64-bit ARM hardware by AMD.

Anyways, I recommend enabling it in all the configs where it is
currently not set. What do you think? If that's a good idea, can you
send a revised patch?

Don't worry about building all the kernels if that's a burden; I'll
check that they build before pushing.
