  target/ppc: Remove pp_check() and reuse ppc_hash32_pp_prot() (2024-05-24 08:57:51 +1000)

----------------------------------------------------------------
* Fix an interesting TLB invalidate race
* Implement more instructions with decodetree
* Add the POWER8/9/10 BHRB facility
* Add missing instructions, registers, SMT support
* First round of a big MMU xlate cleanup

Glenn Miles (4):
      This commit is preparatory to the addition of Branch History Rolling Buffer (BHRB) functionality, which is being provided today starting with the P8 processor.
      This commit continues adding support for the Branch History Rolling Buffer (BHRB) as is provided starting with the P8 processor and continuing with its successors.  This commit is limited to the recording and filtering of taken branches.
      Add support for the clrbhrb and mfbhrbe instructions.
      Adds migration support for Branch History Rolling Buffer (BHRB) internal state.
