Subject: [PATCH] x86_64: x86_64 setup.c - printing cmp related boottime information
X-Git-Tag: v2.6.18-rc1~612^2~18
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=e42f94373764d825e2c0464092738f66f5d3effb;p=~emulex%2Finfiniband.git

[PATCH] x86_64: x86_64 setup.c - printing cmp related boottime information

Getting phys_proc_id and cpu_core_id information to be printed at boot
time for AMD processors.  Also matching the Node related boot time
information that gets printed for Intel and AMD processors for NUMA
configurations.
