Multiple reports from users were received regarding failures of packet 'g' communication with gdb for some MIPS configurations. It was found out (by bisecting) that the problematic commit is 8e0b373. Revert that commit until a better solution is developed.

2019-09-12target/mips: Switch to do_transaction_failed() hookPeter Maydell
Switch the MIPS target from the old unassigned_access hook to the new do_transaction_failed hook. Unlike the old hook, do_transaction_failed is only ever called from the TCG memory access paths, so there is no need for the "ignore this if we're using KVM" hack that we were previously using to work around the way unassigned_access was called for all kinds of memory accesses to unassigned physical addresses. The MIPS target does not ever do direct memory reads by physical address (via either ldl_phys etc or address_space_ldl etc), so the only memory accesses this affects are the 'normal' guest loads and stores, which will be handled by the new hook; their behaviour is unchanged.

2019-09-03mips/tcg: Call probe_write() for CONFIG_USER_ONLY as wellDavid Hildenbrand
Let's call it also for CONFIG_USER_ONLY. While at it, add a FIXME and get rid of one local variable. MIPS code probably needs a bigger refactoring in regards of ensure_writable_pages(), similar to s390x, so for example, watchpoints can be handled reliably later. The actually accessed addresses should be probed only, not full pages.

2019-09-03target/mips: Hard code size with MO_{8|16|32|64}Tony Nguyen
Temporarily no-op size_memop was introduced to aid the conversion of memory_region_dispatch_{read|write} operand "unsigned size" into "MemOp op". Now size_memop is implemented, again hard coded size but with MO_{8|16|32|64}. This is more expressive and avoids size_memop calls.

2019-09-03target/mips: Access MemoryRegion with MemOpTony Nguyen
The memory_region_dispatch_{read|write} operand "unsigned size" is being converted into a "MemOp op". Convert interfaces by using no-op size_memop. After all interfaces are converted, size_memop will be implemented and the memory_region_dispatch_{read|write} operand "unsigned size" will be converted into a "MemOp op". As size_memop is a no-op, this patch does not change any behaviour.
