Fwd: Warning about kernel 4.2 performance (revised)

Hi,

we may have better luck with KVM for the forseeable future than with
VM86. I submitted a proof-of-concept PR here:
https://github.com/stsp/dosemu2/pull/90, based on this article:
http://lwn.net/Articles/658511/

At least on Westmere+ CPUs (first gen Core i3/i5/i7) KVM can run
"unrestricted guest" mode which behaves like real mode and seems just
as fast as vm86() but it traps less than vm86 so some things that
dosemu depends upon (e.g. that INTs are trapped) do not work. That can
be worked around though with some more coding.

(Yes I am still alive but Stas has for more time than me to work on
DOSEMU so I wish him good luck with dosemu2 so that's why I sent the
PR to dosemu2).

Regards,
Bart
