OpenBSD Errata: January 17th, 2020 (inteldrmctx)

Errata patches for the kernel have been released for OpenBSD 6.5 and 6.6.

Execution Unit state was not cleared on context switch with Intel Gen9
graphics hardware.

Binary updates for the amd64 and i386 platforms are available via the
syspatch utility. Source code patches can be found on the respective
errata page:

  https://www.openbsd.org/errata65.html
  https://www.openbsd.org/errata66.html

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