Use the newly added Broadwell cache event list for Haswell too.
All Haswell and Broadwell events and offcore masks used in these lists
are identical.
However Haswell is very different from the Sandy Bridge
list that was used previously. That fixes a wide range of mis-counting

Add Broadwell support for Broadwell Client to perf.
This is very similar to Haswell. It uses a new cache event table,

save_xstate_sig()->drop_init_fpu() doesn't look right. setup_rt_frame()
can fail after that, in this case the next setup_rt_frame() triggered
by SIGSEGV won't save fpu simply because the old state was lost. This

Change this code to initialize the members explicitly.

- F2x1xx addresses were stopped from being mapped explicitly to DCT1
from F15h (OR) onwards. They use _dct[0:1] mechanism to access the

DCT for these families.
