SubjectRegression introduced by cf6d445f68974d0b15a14cf6021be38a91f2b5d8
Date
Hello,

I've hit a regression that was introduced by the commit in $SUBJECT. I'm
building a minimal kernel config that doesn't have CONFIG_SMP set, which
results in the topology for the box to look different than with
CONFIG_SMP set. Specifically boot_cpu_data.x86_max_cores comes out to 16
without CONFIG_SMP set, but 12 with CONFIG_SMP set. So when we are doing
the init for the uncore_msr_uncores types we panic when trying to do
uncore_box_init on the 13th box for hswep_uncore_cbox when doing the
wrmsrl in snbep_uncore_msr_init_box(). I'm hoping this makes sense to
you, because this is all greek to me. For now I've just enabled
CONFIG_SMP (it only adds like .1 mb to my image), but I figure we should
probably fix this. It takes me no time to reproduce so I can test
whatever patch you come up with, or run whatever debugging you want me
to run. Thanks,

Josef
