Andreas Färber c658b94f6e cpu: Turn cpu_unassigned_access() into a CPUState hook
Use it for all targets, but be careful not to pass invalid CPUState.
cpu_single_env can be NULL, e.g. on Xen.

Refactor common code around calls to cpu_restore_state().

tb_find_pc() has now no external users, make it static.

Avi Kivity a8170e5e97 Rename target_phys_addr_t to hwaddr
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

Blue Swirl 0184e266cb Sparc: avoid AREG0 wrappers for memory access helpers
Adjust generation of load and store templates so that the functions
take a parameter for CPUState instead of relying on global env.

Remove wrappers. Move remaining memory helpers to ldst_helper.c.

Richard Henderson 30038fd818 target-sparc: Change fpr representation to doubles.
This allows a more efficient representation for 64-bit hosts.
It should be about the same for 32-bit hosts, as we can still
access the individual pieces of the double.
