Smooshing these two patch sets back together for review bandwidth.
I hope to make this the next tcg-next pull.

There are three from the first half, tlbentryfull, which are new.
These are following a hallway conversation with Peter about bits
in MemTxAttrs that are not actually related to memory transactions,
and infrastructure to address a to-do in an Arm patch set.

There are a few patches from the second half, pcrel, that have not
been reviewed.

FWIW, the target/sparc patch fails (the peril of insufficiently tested airport updates), 
so I'm going to drop 7+8 until I have time to investigate.  I'm also going to drop patch 9 
for now, and present it alongside the Arm patch that will use it.

But otherwise, gentle ping.

If it helps, the test case that exercises the IE (Invert Endian) page bit in 
target/sparc is Milax (OpenSolaris) which uses it to map PCI devices. Grab a suitable 
copy of milax032sparc.iso and test with:

     qemu-system-sparc64 -m 256 -cdrom milax032sparc.iso -nographic -boot d

You should see the IE pages accessed at the point where it starts poking the CDROM 
device, and timeouts if it isn't working.


ATB,

Mark.
