Title:
  linux: VM86 should be disabled

Status in linux package in Ubuntu:
  Triaged

Bug description:
  Upstream is concerned about possible security vulnerabilities in VM86:
  http://thread.gmane.org/gmane.linux.kernel/1991020

  There are possible side effects to disabling VM86, e.g.,
  (http://codesearch.debian.net/results/sys%2Fvm86.h) and
  (http://codesearch.debian.net/results/asm%2Fvm86.h). Applications
  including asm/vm86.h directly may not have an emulation fallback mode
  and may therefore fail to run or build.

  VM86 is also a dependency for some older 32 bit X drivers.

  It seems the choice is to regress or orphan some 32 bit functionality,
  or leave all 32 bit platform open to possible VM86 vulnerabilities.
