      x86-32: Rework cache flush denied handler · 40d2e763
      Brian Gerst authored
      The cache flush denied error is an erratum on some AMD 486 clones.  If an invd
      instruction is executed in userspace, the processor calls exception 19 (13 hex)
      instead of #GP (13 decimal).  On cpus where XMM is not supported, redirect
      exception 19 to do_general_protection().  Also, remove die_if_kernel(), since
      this was the last user.
