2013-12-20Add VSR to Global RegistersTom Musta1-0/+27
This patch adds VSX VSRs to the the list of global register indices. More specifically, it adds the lower halves of the first 32 VSRs to the list of global register indices. The upper halves of the first 32 VSRs are already defined via cpu_fpr[]. And the second 32 VSRs are already defined via the cpu_avrh[] and cpu_avrl[] arrays.

2013-12-20powerpc: add PVR mask supportAlexey Kardashevskiy5-0/+56
IBM POWERPC processors encode PVR as a CPU family in higher 16 bits and a CPU version in lower 16 bits. Since there is no significant change in behavior between versions, there is no point to add every single CPU version in QEMU's CPU list. Also, new CPU versions of already supported CPU won't break the existing code. This adds PVR value/mask support for KVM, i.e. for -cpu host option. As CPU family class name for POWER7 is "POWER7-family", there is no need to touch aliases.
