Re: [Xen-devel] RE: [Patch] Add NMI Injection and Pending Support in VMX

[Keir Fraser <keir@xxxxxxxxxxxxx>]

Hi Haiato,

Checked in as 15466:e6d5e4709466 (see
http://xenbits.xensource.com/staging/xen-unstable.hg).

But I 'fixed it' in a number of ways. :-) So please take a look and see if
you think I missed anything important. I particularly didn't like your
restructuring inside vmx_intr_assist() so I stripped that out.
