powerpc userland broken b/w 2020/06/21 00:39 to 06/22 05:34 UTC

[Rin Okuyama <rokuyama.rk%gmail.com@localhost>]

For powerpc ports, src/sys/arch/powerpc/mcontext.h rev 1.20
(existed b/w 2020/06/21 00:39:59 to 2020/06/22 05:34:57)
turned out to be incorrect.

Userland built with this file does not work on kernel as of today.

If you have installed that userland, you need to install base.tgz,
i.e., libc, rtld, and libpthread, *prior* to updating kernel.
Then, update kernel and other userland binaries.

If you didn't installed the affected userland, you can (and should)
follow normal updating path.

I am so sorry for the inconvenience.

Thanks,
rin
