Anthony,
the following changes since commit 6a4e17711442849bf2cc731ccddef5a2a2d92d29:
Remove Sun4c, Sun4d and a few CPUs (2013-05-26 11:37:58 +0000)
are available in the git repository at:

This is part 2 of the memory/IOMMU patches. These reorganize the
handling of unassigned accesses so that they are propagated as
errors during I/O dispatch. In the end, a return value is added to
address_space_rw/read/write. This is particularly useful when an IOMMU
is available, because it lets devices detect faulting accesses.
All patches were reviewed by rth.

exec: eliminate io_mem_ram
exec: drop useless #if
cputlb: simplify tlb_set_page
exec: make io_mem_unassigned private

memory: dispatch unassigned accesses based on .valid.accepts
memory: add address_space_translate
memory: move unassigned_mem_ops to memory.c
memory: assign MemoryRegionOps to all regions
exec: expect mr->ops to be initialized for ROM
exec: introduce memory_access_is_direct
exec: introduce memory_access_size
memory: export memory_region_access_valid to exec.c
exec: implement .valid.accepts for subpages
memory: add address_space_access_valid

memory: add big endian support to access_with_adjusted_size
memory: split accesses even when the old MMIO callbacks are used
memory: correctly handle endian-swapped 64-bit accesses
exec: just use io_mem_read/io_mem_write for 8-byte I/O accesses
memory: propagate errors on I/O dispatch
memory: add return value to address_space_rw/read/write
