Note that while such functions may exist both for *-user and softmmu,
only *-user uses the CPUState hook, while softmmu reuses the prototype
for calling it directly.

Pages should be flagged executable only if the tlb executable flag is
set or the mmu is off.

memory
Where *software* leaves 0x0000 - 0x2000 unmapped, the hardware should
still allow for this area to be mapped.

The result of (rw & 0) is always zero and therefore a logic false.
The whole comparison will therefore never be executed, it is a obvious bug,
we should use !(rw & 1) here.

Change breakpoint_invalidate() argument to CPUState alongside.
Since all targets now assign a softmmu-only field, we can drop helpers
cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd().
Prepares for changing cpu_memory_rw_debug() argument to CPUState.

Instead of calling openrisc_env_get_cpu(), casting to CPU() via the
ENV_GET_CPU() compatibility macro and casting back to OPENRISC_CPU(),
just call openrisc_env_get_cpu() directly.
ENV_GET_CPU() is meant as workaround for target-independent code only.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"
| xargs s/target_phys_addr_t/hwaddr/g' origin
