Manjunath Matti ee7f4c54e1 powerpc: Add HWCAP3/HWCAP4 data to TCB for Power Architecture.
This patch adds a new feature for powerpc.  In order to get faster
access to the HWCAP3/HWCAP4 masks, similar to HWCAP/HWCAP2 (i.e. for
implementing __builtin_cpu_supports() in GCC) without the overhead of
reading them from the auxiliary vector, we now reserve space for them
in the TCB.
