Subject: KVM: Remove the 'emulated' field from the userspace interface
X-Git-Tag: v2.6.22-rc1~1008^2~57
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=106b552b43beac2694df5fbafc8f125a72df5f65;p=linux-2.6

KVM: Remove the 'emulated' field from the userspace interface

We no longer emulate single instructions in userspace.  Instead, we service
mmio or pio requests.
