Recent virtio refactoring in QEMU made virtio-bus become the parent bus
of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation,
typename will be added to fw_dev_path by default, the new fw_dev_path
could not be identified by seabios. It causes that bootindex parameter
of scsi device doesn't work.

This patch implements get_fw_dev_path() in BusClass, it will be called
if bus doesn't implement the method, tyename will be added to
fw_dev_path. If the implemented method returns NULL, nothing will be
added to fw_dev_path.

It also implements virtio_bus_get_fw_dev_path() to return NULL. Then
QEMU will still pass original style of fw_dev_path to seabios.

glibc wipes malloc(3) memory when the MALLOC_PERTURB_ environment
variable is set.  The value of the environment variable determines the
bit pattern used to wipe memory.  For more information, see
http://udrepper.livejournal.com/11429.html.

Set MALLOC_PERTURB_ for gtester and qemu-iotests.  Note we pick a random
value from 1 to 255 to expose more bugs.  If you need to reproduce a
crash use 'show environment' in gdb to extract the MALLOC_PERTURB_
value from a core dump.

Both make check and qemu-iotests pass with MALLOC_PERTURB_ enabled.

When pc-sysfw.rom_only == 0, flash memory will be
usable with kvm. In order to enable flash memory mode,
a pflash device must be created. (For example, by
using the -pflash command line parameter.)

Usage of a flash memory device with kvm requires
KVM_CAP_READONLY_MEM, and kvm will abort if
a flash device is used with an older kvm which does
not support this capability.

If a flash device is not used, then qemu/kvm will
operate in the original rom-mode.

For readonly memory regions and rom devices in romd_mode,
we make use of the KVM_MEM_READONLY. A slot that uses

For rom devices with !romd_mode, we force the slot to be

The isapc machine with seabios currently requires the BIOS region
to be read/write memory rather than read-only memory.

KVM currently cannot support the BIOS as a ROM region, but qemu
in non-KVM mode can. Based on this, isapc machine currently only
works with KVM.

To work-around this isapc issue, this change avoids marking the
BIOS as readonly for isapc.

This change also will allow KVM to start supporting ROM mode
via KVM_CAP_READONLY_MEM.

This is because we call back into Cocoa from threads other than
the UI thread (specifically from the CPU thread). Since we created
these threads via the POSIX API rather than NSThread, they don't have
automatically created autorelease pools. Guard all the functions where
QEMU can call back into the Cocoa UI code with autorelease pools
so that we don't leak any Cocoa objects.

9P optionally uses the FS_IOC_GETVERSION ioctl to get information about
a file's version (sometimes called generation number).

The code checks for supported filesystems at mount time, but some paths
may come from other mounted filesystems.

Change it to treat unsupported paths the same as unsupported
filesystems, returning 0 in both cases.

Note: ENOTTY is the error code for an unsupported ioctl.

This fix allows booting a linux kernel with the same / filesystem as the
host; otherwise the boot fails when mounting devtmpfs.

TCGv changes size depending on the compile time value of
TARGET_LONG_BITS.  This is useful for generating code for MIPS style
"instructions are the same but the register width changes" CPUs, and
also for the generic bits of QEMU which operate on "width of a
virtual address" values, but mostly in the ARM target code we were
using it purely as a shorthand for "any 32 bit value".

This needs to change in preparation for AArch64 support, since an
AArch64-capable v8 core will have 64 bit virtual addresses but still
use 32 bit values for the 32 bit instruction set.

This patch mechanically converts all the occurrences of TCGv,
tcg_temp_new(), tcg_temp_free(), tcg_temp_local_new() and
TCGV_UNUSED() to their explicitly 32 bit counterparts.  This is
correct for everything except the arguments to tcg_gen_qemu_{ld,st}*,
which really do need to be TCGv and so will require a 32-to-64
conversion when building the 32 bit code for AArch64.  Those changes
will be in a separate patch for easier review.
