In TCG mode, iothread and vcpus run in lock-step. So it's pointless to
send a signal from qemu_cpu_kick to the vcpu thread - if we got here,
the receiver already left the vcpu loop.

Polling until select returns empty fdsets helps to reduce the switches

If we call select without a timeout, it's more efficient to keep the
global mutex locked as we may otherwise just play ping pong with a
vcpu thread contending for it. This is particularly important for TCG
mode where we run in lock-step with the vcpu thread.

The legacy functions that we're wrapping expect that offset
to be included in the register.  Indeed, they generally
expect the absolute address and then mask off the "high" bits.

The FDC is the first converted device with a non-zero offset.

After 312b4234, the APIC and PCI devices are colliding with each other.  This
is harmless in practice because the APIC accesses are special cased and never
make there way onto the bus.

Avi is working on a proper fix, but until that's ready, avoid printing the
warning.

The current implementation of PAM and the PCI holes is broken in several
ways:

  - PCI BARs are not restricted to the PCI hole (a BAR may hide memory)
  - PCI devices do not respect PAM (if a PCI device maps a region while
    PAM maps the region to RAM, the request will be honored)

This patch fixes things by introducing a pci address space, and using
memory region aliases to represent PAM regions, SMRAM, and PCI holes.

The memory hierarchy looks something like

system_memory
 |
 +--- low memory alias (0-0xe0000000)
 |      |
 |      +-- ram@0
 |
 +--- high memory alias (0x100000000-EOM)
 |      |
 |      +-- ram@0xe0000000
 |
 +--- pci hole alias (end of low memory-0x100000000)
 |      |
 |      +-- pci@end-of-low-memory
 |
 |
 +--- pam[n] (0xc0000-0xc3fff etc) (when set to pci, priority 1)
 |      |
 |      +-- pci@0xc4000 etc
 |
 +--- smram (0xa0000-0xbffff) (when set to pci/vga, priority 1)
        |
        +-- pci@0xa0000 etc

ram (simple ram region)

pci
 |
 +--- BARn
 |
 +--- VGA 0xa0000-0xbffff
 |
 +--- ROMs
