Re:[PATCH] Mobil Pentium 4 HT and the NMI

[Steven Rostedt]

Hi,

I'm resending this since I don't see it in git yet, and I'm wondering if
there is a problem with this patch.  I have a IBM ThinkPad G41 with a
Mobile Pentium 4 HT.  Without this patch, the NMI won't be setup.  Is
there a reason that if the x86_model is greater than 0x3 it will return.
Since my processor has a 0x4 x86_model, I upped it to that. Otherwise my
laptop won't be able to use the NMI.

Thanks,

-- Steve

Description:
  This patch is to allow the Mobile Penitum 4 HT to use the NMI.
