diminished takes two caps and asserts that one is equal to the other
except that one may have fewer rights. We remove this definition and all
references to it, replacing diminished with equality.
ARM setCurrentPD was recently refactored as part of multi-VM support for
ARM_HYP. The Haskell was updated correctly, and the C was not.
Unfortunately, setCurrentPD was manually redefined in MachineOps.thy for
ARM hiding the change, making the C look correct when it wasn't.
We scrap the second definition of setCurrentPD, load it from the Haskell,
and have an abstract set_current_pd that's a bit simpler to refine down
from.
The proofs are updated for the above change and the update to the C
setCurrentPD that was breaking on KZM.
message_info structs have 20 bit labels. On 32-bit systems, the label
does not need to be masked as there are no extra padding bits in the
struct, but this is not true for 64-bit systems. As a result, the
haskell needs to mask msgLabelBits (=20) when extracting the label in
messageInfoFromWord.
in addition to the a_type ATCB simplification, the following two are now in the simpset:
"a_type (Endpoint x) = AEndpoint"
"a_type (Notification v) = ANTFN"
now that we have valid_vspace_objs to express validiy of
vspace objects, we do not need valid_arch_objs: we have
valid_objs to state the validity of non-vspace arch objects.
