When adding a rom_device in I/O mode, we incorrectly masked off the low
bits, resulting in a pure RAM map. Fix my masking off the high bits and
IO_MEM_ROMD, yielding a pure I/O map.

The a7 area was set up as an alias of itself, rather than the p4 area. This
sent the memory core into infinite recursion.
Fix by aliasing the a7 area to the p4 area.

Use enum TCGOpcode instead of plain old int so that the name of
current op can be seen in GDB. Add a default case to switch
so that GCC does not complain about unhandled enum cases.

Remove PROVIDE_HIDDEN and ONLY_IF_{RO,RW} from linker scripts to make

The first issue is the hard coded POSIX Real Time extensions library in the
libcacard/Makefile. From looking at the code it doesn't seem this is necessary
anyway. Robert Relyea seems to think it most likely isn't necessary.
The second issue was the missing exclusion of the BSD userland binary
builds from the addition of this Makefile target for the smartcard NSS
code which breaks the builds if smartcard NSS support is enabled.

When the vhost notifier is disabled, the userspace handler runs
immediately: virtio_pci_set_host_notifier_internal might
call virtio_queue_notify_vq.
Since the VQ state and the tap backend state aren't
recovered yet, this causes
"Guest moved used index from XXX to YYY" assertions.
The solution is to split out host notifier handling
from vhost VQ setup and disable notifiers as our last step
when we stop vhost-net. For symmetry enable them first thing
on start.

Some gcc versions do not properly detect that all possible cases are
covered and base and size are always initialized. Please gcc by defining
a pseudo default case.

Commit c62f6d1 (monitor: fix build breakage with --disable-vnc)
conditionalised some VNC setup code but left an unused variable. Move
the variable into the conditional code to fix the build breakage.

cfi02 is annoying in that is ignores some address bits; we probably
want explicit support in the memory API for that.

The code will remap all PAMs, even if just one is updated, resulting
in reduced performance. Wrap in a transaction to detect that those
other PAMs have not changed.

ppc maps the escc mmio region both at a fixed offset (as a sysbus area) and as part of a PCI BAR.
This crashes, since a MemoryRegion may have only one parent. Use an alias so we have a separate
MemoryRegion for the BAR.
Signed-off-by: Avi Kivity <avi@redhat.com>
The map/unmap code was assymetric - unmap used the local MemoryRegion while
map used isa_mmio_init(), which cannot handle dynamic mappings.
Fix by using isa_mmio_setup() and the local MemoryRegion.
