2015-03-09target-ppc: Add versions to server CPU descriptionsAlexey Kardashevskiy
5b79b1c "target-ppc: Create versionless CPU class per family if KVM" added a dynamic CPU class registration with the name of the CPU family which QEMU is running on. For example, this allowed specifying "-cpu POWER7" on every version of POWER7 machine, not just the one which POWER7 was an alias of. I.e. before 5b79b1c, "-cpu POWER7" would not work on real POWER7 2.1 and would work on POWER7 2.3 only. The same story for POWER8. However that patch broke POWER5+ support as POWER5+ CPU uses the same name as the CPU class so dynamic registering of the POWER5+ class failed. This redefines POWER5+ server CPUs by adding a version to them and adding an alias for TCG case. KVM will use dynamically registered CPUs. While we are here, do the same for 970 CPU.

2015-03-09PPC: Introduce the Virtual Time Base (VTB) SPR registerCyril Bur
This patch adds basic support for the VTB. PowerISA: The Virtual Time Base (VTB) is a 64-bit incrementing counter. Virtual Time Base increments at the same rate as the Time Base until its value becomes 0xFFFF_FFFF_FFFF_FFFF (2 64 - 1); at the next increment its value becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when this occurs. The operation of the Virtual Time Base has the following additional properties. 1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of the Virtual Time Base. 2. Copying the contents of a GPR to the Virtual Time Base replaces the contents of the Virtual Time Base with the contents of the GPR.

2015-03-09target-ppc: force update of msr bits in cpu_post_loadMark Cave-Ayland
Since env->msr has already been restored by the time cpu_post_load is called, make sure that ppc_store_msr() is explicitly called with all msr bits except MSR_TGPR marked as invalid. This solves the issue where MSR flags aren't set correctly when restoring a VM snapshot, in particular the internal env->excp_prefix value when MSR_EP has been altered by a guest.

2015-03-09target-ppc: Use right page size with hash table lookupAneesh Kumar K.V
We look at two sizes specified in ISA (4K, 64K). If not found matching, we consider it 16MB. Without this patch we would fail to lookup address above 16MB range. Below 16MB happened to work before because the kernel have a liner mapping and we always looked up hash for 0xc000000000000000. The actual real address was computed by using the 16MB offset with the real address found with the above hash.

2015-01-20exec.c: Drop TARGET_HAS_ICE define and checksPeter Maydell
The TARGET_HAS_ICE #define is intended to indicate whether a target-* guest CPU implementation supports the breakpoint handling. However, all our guest CPUs have that support (the only two which do not define TARGET_HAS_ICE are unicore32 and openrisc, and in both those cases the bp support is present and the lack of the #define is just a bug). So remove the #define entirely: all new guest CPU support should include breakpoint handling as part of the basic implementation.
