We have an end parameter in all the callers, and this make it coherent
with the rest of cpu_physical_memory_* functions, that also take a
length parameter.
Once here, move the start/end calculation to
tlb_reset_dirty_range_all() as we don't need it here anymore.

IEEE754-2008 specifies a new rounding mode:
"roundTiesToAway: the floating-point number nearest to the infinitely
precise result shall be delivered; if the two nearest floating-point
numbers bracketing an unrepresentable infinitely precise result are
equally near, the one with larger magnitude shall be delivered."
Implement this new mode (it is needed for ARM). The general principle
is that the required code is exactly like the ties-to-even code,
except that we do not need to do the "in case of exact tie clear LSB
to round-to-even", because the rounding operation naturally causes
the exact tie to round up in magnitude.

Currently the int-to-float functions take types which are specified
as "at least X bits wide", rather than "exactly X bits wide". This is
confusing and unhelpful since it means that the callers have to include
an explicit cast to [u]intXX_t to ensure the correct behaviour. Fix
them all to take the exactly-X-bits-wide types instead.
Note that this doesn't change behaviour at all since at the moment
we happen to define the 'int32' and 'uint32' types as exactly 32 bits
wide, and the 'int64' and 'uint64' types as exactly 64 bits wide.

function removes the child from the namespace and decrements the

There should be no need to look up nor enumerate the interface "types",
whose "classes" are really just vtables. Just create the types and
add them to the interface list of the parent type.
Interfaces not registering their type anymore means that accessing
superclass::interface by type name will fail when initializing
subclass::interface. Thus, we need to pre-initialize the subclass's
parent_type field before calling type_initialize. Apart from this, the
interface "types" should never be used and thus it is harmless to leave
them out of the hashtable.
Further, the interface types had a bug with interfaces that are
inherited from a superclass: The implementation type name was wrong
(for example it was subclass::superclass::interface rather than
just subclass::interface). This patch fixes this as well.

The object-cast and class-cast caches cannot be shared because class
caching is conditional on the target type not being an interface and
object caching is unconditional. Leads to a bug when a class cast
to an interface follows an object cast to the same interface type:
FooObject = FOO(obj);
FooClass = FOO_GET_CLASS(obj);
Where TYPE_FOO is an interface. The first (object) cast will be
successful and cache the casting result (i.e. TYPE_FOO will be cached).
The second (class) cast will then check the shared cast cache
and register a hit. The issue is, when a class cast hits in the cache
it just returns a pointer cast of the input class (i.e. the concrete
class).
When casting to an interface, the cast itself must return the
interface class, not the concrete class. The implementation of class
cast caching already ensures that the returned cast result is only
a pointer cast before caching. The object cast logic however does
not have this check.
Resolve by just splitting the object and class caches.

Make the 32bit pci hole start at end of ram, so all possible address
space is covered.
We used to try and make addresses aligned so they are easier to cover
with MTRRs, but since they are cosmetic on KVM, this is probably not
worth worrying about.
Of course the firmware can use less than that. Leaving space unused is
no problem, mapping pci bars outside the hole causes problems though.
