-Subject: [PATCH 056/105] MIPS: Fix SMP core calculations when using MT
- support.
-
-The TCBIND register is only available if the core has MT support. It
-should not be read otherwise. Secondly, the number of TCs (siblings)
-are calculated differently depending on if the kernel is configured
-as SMVP or SMTC.
