Add an explicit CPUPPCState parameter instead of relying on AREG0 and rename op_helper.c (which only contains load and store helpers) to mem_helper.c. Remove AREG0 swapping in tlb_fill(). Switch to AREG0 free mode. Use cpu_ld{l,uw}_code in translation and interrupt handling, cpu_{ld,st}{l,uw}_data in loads and stores.

2012-04-15target-ppc: Add hooks for handling tcg and kvm limitationsDavid Gibson
On target-ppc, our table of CPU types and features encodes the features as found on the hardware, regardless of whether these features are actually usable under TCG or KVM. We already have cases where the information from the cpu table must be fixed up to account for limitations in the emulation method we're using. e.g. TCG does not support the DFP and VSX instructions and KVM needs different numbering of the CPUs in order to tell it the correct thread to core mappings. This patch cleans up these hacks to handle emulation limitations by consolidating them into a pair of functions specifically for the purpose.

2012-04-15PPC: Fix TLB invalidation bug within the PPC interrupt handler.Mark Cave-Ayland
Commit 41557447d30eeb944e42069513df13585f5e6c7f also introduced a subtle TLB flush bug. By applying a mask to the interrupt MSR which cleared the IR/DR bits at the start of the interrupt handler, the logic towards the end of the handler to force a TLB flush if either one of these bits were set would never be triggered. This patch simply changes the IR/DR bit check in the TLB flush logic to use the original MSR value (albeit with some interrupt-specific bits cleared) so that the IR/DR bits are preserved at the point where the check takes place.

2012-03-15PPC: KVM: Synchronize regs on CPU dumpAlexander Graf
When we dump the CPU registers, there's a certain chance they haven't been synchronized with KVM yet, so we have to manually trigger that.

2012-03-15pseries: Don't try to munmap() a malloc()ed TCE tableDavid Gibson
For the pseries machine, TCE (IOMMU) tables can either be directly malloc()ed in qemu or, when running on a KVM which supports it, mmap()ed from a KVM ioctl. The latter option is used when available, because it allows the (frequent bottlenext) H_PUT_TCE hypercall to be KVM accelerated. However, even when KVM is persent, TCE acceleration is not always possible. Only KVM HV supports this ioctl(), not KVM PR, or the kernel could run out of contiguous memory to allocate the new table. In this case we need to fall back on the malloc()ed table. When a device is removed, and we need to remove the TCE table, we need to either munmap() or free() the table as appropriate for how it was allocated. The code is supposed to do that, but we buggily fail to initialize the tcet->fd variable in the malloc() case, which is used as a flag to determine which is the right choice. This patch fixes the bug, and cleans up error messages relating to this path while we're at it.
