From: Ben Hutchings
Date: Thu Jun 07 2018 - 11:41:53 EST
3.16.57-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx>
commit 4b3b234f434d440fcd749b9636131b76e2ce561e upstream.
Len Brown noticed something was amiss in our INTEL_FAM6_*
definitions. It seems like model 0x1F was a Nehalem part,
marketed as "Intel Core i7 and i5 Processors" (according to the
SDM). But, although it was a Nehalem 0x1F had some uncore events
which were shared with Westmere.
Len also mentioned he thought it was called "Havendale", which
Wikipedia says was graphics-oriented and canceled:
https://en.wikipedia.org/wiki/Nehalem_(microarchitecture)
So either way, it's probably not imporant what we call it, but
call it Nehalem to be accurate, and add a "G" since it seems
graphics-related. If it were canceled that would be a good reason
why it's so sparsely and inconsistently referred to in the code.
