cpu_interrupt might be called while translating the TB, but before it
is linked into a potentially infinite loop and becomes env->current_tb.
Currently this can (and does) cause huge problems only when using
dyntick clock, with other (periodic) clocks host_alarm_handler will
eventually be executed resulting in a call to cpu_interrupt which will
reset the recursion of running TB and the damage is "only" latency.

Move addi_i64, muli_i64 and subi_i64 out of #if TCG_TARGET_REG_BITS
as both implementations are strictly identical. Use the same
optimisation (ie when imm == 0) for addi_i64 and subi_64 than the
32-bit version.

Revision 5500 of the qemu repository removed all code using
ppc_load_xer & ppc_store_xer as well as their implementation.
Another patch fixes it's usage in kvm-userspace for powerpc, but I think
that header can now be cleaned up, therefore this patch to qemu-devel.

The code in hw/cirrus_vga.c has changed a lot between CVE-2007-1320 has
been announced and the patch has been applied. As a consequence it has
wrongly applied and QEMU is still vulnerable to this bug if using VNC.

It is safe not to set dpy_refresh and that's used to indicate that the display
doesn't need updates. This saves us two wakeups per second.

The motivating goal behind this is to allow other tools to use the CharDriver

The goal of this series is to move the CharDriverState code out of vl.c and
into its own file, qemu-char.c. This patch moves around some declarations so
the next patch can be pure code motion.

With the recent changes to the main loop, we no longer have unconditional
polling. This means we can now sleep in select() for much longer than we
previously did. This patch increases our select() sleep time from 10ms to 5s
which is effectively unlimited since we're going to wake up sooner than that
in almost all circumstances.
With this patch, I see the number of wake-ups with an idle dynamic ticks guest
drop from 80 per second to about 15 times per second.

This patch makes qemu keep track of the character devices in use and
implements a "info chardev" monitor command to print a list.
qemu_chr_open() sticks the devices into a linked list now. It got a new
argument (label), so there is a name for each device. It also assigns a
filename to each character device. By default it just copyes the
filename passed in. Individual drivers can fill in something else
though. qemu_chr_open_pty() sets the filename to name of the pseudo tty
allocated.
Output looks like this:
(qemu) info chardev
monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait
serial0: filename=unix:/tmp/run.sh-26827/console,server
serial1: filename=pty:/dev/pts/5
parallel0: filename=vc:640x480
