OpenBSD Errata: March 27th, 2019 (vmmints)

Errata patches for vmm have been released for OpenBSD 6.3 and 6.4.

GDT and IDT limits were improperly restored during VMM context switches.

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/errata63.html
  https://www.openbsd.org/errata64.html

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