Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.6-20160201' into staging
ppc patch queue for 2016-02-01 Currently accumulated patches for target-ppc, pseries machine type and related devices. * Cleanup of error handling code in spapr * A number of fixes for Macintosh devices for the benefit of MacOS 9 and X * Remove some abuses of the RTAS memory access functions in spapr * Fixes for the gdbstub (and monitor debug) for VMX and VSX extensions. * Fix pseries machine hotplug memory under TCG * Clean up and extend handling of multiple page sizes with 64-bit hash MMUs * Fix to the TCG implementation of mcrfs # gpg: Signature made Mon 01 Feb 2016 02:28:34 GMT using RSA key ID 20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: WARNING: This key is not certified with sufficiently trusted signatures! # gpg: It is not certain that the signature belongs to the owner. # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.6-20160201: (40 commits) target-ppc: mcrfs should always update FEX/VX and only clear exception bits target-ppc: Make every FPSCR_ macro have a corresponding FP_ macro target-ppc: Allow more page sizes for POWER7 & POWER8 in TCG target-ppc: Helper to determine page size information from hpte alone target-ppc: Add new TLB invalidate by HPTE call for hash64 MMUs target-ppc: Split 44x tlbiva from ppc_tlb_invalidate_one() target-ppc: Remove unused mmu models from ppc_tlb_invalidate_one target-ppc: Use actual page size encodings from HPTE target-ppc: Rework SLB page size lookup target-ppc: Rework ppc_store_slb target-ppc: Convert mmu-hash{32,64}.[ch] from CPUPPCState to PowerPCCPU target-ppc: Remove unused kvmppc_read_segment_page_sizes() stub uninorth.c: add support for UniNorth kMacRISCPCIAddressSelect (0x48) register cuda.c: return error for unknown commands pseries: Allow TCG h_enter to work with hotplugged memory target-ppc: gdbstub: Add VSX support target-ppc: gdbstub: fix spe registers for little-endian guests target-ppc: gdbstub: fix altivec registers for little-endian guests target-ppc: gdbstub: introduce avr_need_swap() target-ppc: gdbstub: fix float registers for little-endian guests ...
