We would prefer patches for 5.4, and we can probably carry them in our linu=
x-
lts package, but we should make sure that Natanael is okay with that as he=

leads kernel maintenance in Alpine.  Otherwise, we can provide a patched=20
kernel as we do with linux-octeon.

No need to learn anything, just start sending us patches, I will talk with =
the=20
infra team and other mips porters to see if there is any interested parties=
 in=20
maintaining the build hardware for mips64el.  Once we have a plan on that=20
front, we can talk about hardware.  Or Loongson could maintain the builder =
if=20
that is more interesting. :)

Right now, we are in temporary feature freeze as we prepare to branch the 3=
=2E12=20
release.  My suggestion as an initial starting point would be to submit a=20
mips64el profile for linux-lts that supports booting on Loongson hardware. =
=20
This is something that could be merged during feature freeze as it does not=
=20
have any practical impact on the release.

My thoughts are that we should have Loongson as the primary focus of mips64=
el=20
and Octeon as the primary focus of mips64, as I believe Loongson does not=20
support big endian operation.  If I am wrong, it may be nice to support bot=
h=20
Octeon and Loongson in these configurations.

I would be happy to review and push the kernel change as a starting point,=
=20
feel free to tag me in gitlab (my username is @kaniini).
