Port of JEP 386: Alpine Linux Port to jdk8u

[Aleksei Voitylov]

Hi Stephanie,

when briefly looking through the changed filenames I stumbled upon
cpu/ppc/vm, os_cpu/linux_ppc/vm and couldn't recollect having to touch
these directories in JEP 386. So, I wanted to ask a question:

Is this a backport of the set of changes that were committed upstream to
OpenJDK 16 in JEP 386 (or a backport from 11u backports I recently did)?
Or is this some original work Microsoft has done for 8u shared code and
PPC in particular?

Thanks,

-Aleksei

A backport of JDK-8247589 to 11u has recently been integrated by BellSoft, and many OpenJDK vendors (BellSoft Liberica, Azul Zulu, Amazon Corretto) provide a jdk8 for Alpine Linux. We believe there is sufficient user demand for Alpine/musl support on jdk8u, but would be interested in the opinions of other vendors on this as well.

That 8u322 based binary passes builds on all platforms (i.e. No regressions on other platforms) and the AQAVit test suite. The Eclipse Temurin Compliance group also reported that the TCK passed.
