Errata patches for pmapglobal have been released for OpenBSD 6.8 and 6.9.

Recent Intel machines could crash or hang as global mappings were
not flushed from TLB.

Binary updates for the amd64 platform are available via the syspatch
utility.  Source code patches can be found on the respective errata
page:

  https://www.openbsd.org/errata68.html
  https://www.openbsd.org/errata69.html

As these affect the kernel, a reboot will be needed after patching.
