Subject: [PATCH 0/2 v2] speeding up cpu_up()
Date: Fri,  8 May 2015 02:37:53 -0400	[thread overview]
Message-ID: <1431067075-11449-1-git-send-email-lenb@kernel.org> (raw)

Thanks for testing, Aravind, Borislav,

I went with Ingo's suggestion to made this a quirk.
However, I went with a white-list instead of a black-list,
because fewer comparisons are needed for modern processors.
Families are added infrequently, and finally, we get the option
to stick something other than 0 in the table if it we need to.

Let me know if I got the AMD family #'s right.

thanks,
-Len Brown, Intel Open Source Technology Center
