Since commit 8da3ff180974732fc4272cb4433fef85c1822961 ("MMIO callback
interface changes"), the addresses passed to the I/O functions are an
offset to the start of the area. As a consequence, there is no need to
correct the address using the value of IOBR. This make possible the use
of the default MMIO functions. Moreover the addresses are now remaped
when the value if IOBR change.
The memory area corresponds to the devices behing the PCI bus, it should
not be mapped by the PCI controller. Remove the corresponding code.

IDE and flash are part of the R2D board, and can't be removed. Emulate
them even if there is no hard-drive plugged to the IDE or if the flash

Fix a case where an exception happens with the
instruction in the delay slot.
Recovery of branch condition in the exception handling
code was not converted to TCG. Because the condition
was bogus, wrong NPC could be selected from the two
candidates.
A nice bug report with a test case can be found in:
https://bugs.launchpad.net/qemu/+bug/551814
Fix based on patch by Fabrice Bellard.

There are many problems with net_set_boot_mask():
1) It is broken when using the device model instead of "-net nic". Example:
$ qemu-system-x86_64 -device rtl8139,vlan=0,id=net0,mac=52:54:00:82:41:fd,bus=pci.0,addr=0x4 -net user,vlan=0,name=hostnet0 -vnc 0.0.0.0:0 -boot n
Cannot boot from non-existent NIC
$
2) The mask was previously used to set which boot ROMs were supposed to be
loaded, but this was changed long time ago. Now all ROM images are loaded,
and SeaBIOS takes care of jumping to the right boot entry point depending on
the boot settings.
3) Interpretation and validation of the boot parameter letters is done on
the machine type code. Examples: PC accepts only a,b,c,d,n as valid boot
device letters. mac99 accepts only a,b,c,d,e,f.
As a side-effect of this change, qemu-kvm won't abort anymore if using "-boot n"
on a machine with no network devices. Checking if the requested boot device is
valid is now a task for the BIOS or the machine-type code.

If we complete a request with a failure we need to remove it from the list of
requests that are in flight. If we don't do it, the next time the same AIOCB is
used for a cluster allocation it will create a loop in the list and qemu will
hang in an endless loop.

Previously multiwrite_user_cb was never called if a request in the multiwrite

When two requests of the same multiwrite batch fail, the callback of all
requests in that batch were called twice. This could have any kind of nasty
effects, in my case it lead to use after free and eventually a segfault.

When using virtio-console on s390, the input doesn't work.
The root of the problem is rather simple. What happens is the following:
1) create character device for stdio
2) char device is done creating, sends OPENED event
3) virtio-console adds handlers
4) no event comes because the char device is open already
5) virtio-console doesn't accept input because it didn't
receive an OPENED event
To make that sure virtio-console gets notified that the character device
is open even when it's been open from the beginning, this patch introduces
a variable that keeps track of the opened state. If the device is open when
the event handlers get installed, we just notify the handler.
This fixes input with virtio-console on s390.

V2 that uses endaddr = end-of-guest-address-space if !h2g_valid(endaddr)
after I found out that indeed works; and also disables the FreeBSD 6.x
/compat/linux/proc/self/maps fallback because it can return partial lines
if (at least I think that's the reason) the mappings change between
subsequent read() calls.

Commit b305b9d7d6990e492966ffb1fdf619482adeb7e2 made building of virtio-pci
conditional and not enabled on S390x, because it collides with the S390 bus.
Commit 087431d1d1bf4e785edfa89e8cd05fcdac558dc3 accidentially reverted that
behavior, breaking S390x again.
So here's a follow-up patch disabling building of virtio-pci on S390x again.
This unbreaks the S390x target.

With argument checking for cpu_fprintf, gcc throws this warning:
CC i386-softmmu/helper.o
cc1: warnings being treated as errors
/qemu/ar7/target-i386/helper.c: In function ‘cpu_x86_dump_seg_cache’:
/qemu/ar7/target-i386/helper.c:220: error: format not a string literal and no format arguments
The code is correct, but current gcc versions don't detect this.
Therefore the patch rewrites the statement to satisfy the compiler.

Delete inline functions from tcg-target.h that don't need to be there,
move the others to tcg-target.c. Add 'Z', 'I', 'J' constraints for
0, signed 11-bit, and signed 5-bit respectively. Add GUEST_BASE support
similar to ppc64, with the value stored in a register. Add missing
registers to reg_alloc_order. Add support for 12-bit branch relocations.
Add functions for synthetic operations: addi, mtctl, dep, shd, vshd, ori,
andi, shifts, rotates, multiply, branches, setcond. Split out TLB reads
from qemu_ld and qemu_st; fix argument loading for tlb external calls.
