s390x: add ldeb instruction

While running perl, we encountered the ldeb instruction to be used,
so we implement it :).

s390x: make ipte 31-bit aware

When running 31-bit code we can potentially map the same virtual
address twice - once as 0x0yyyyyyy and once as 0x8yyyyyyy, because
the upper bit gets ignored.

This also should be reflected in the tlb invalidation path, so we...

s390x: update R and C bits in storage key

When the s390x maps a page or writes happen to a page, the R and C
bits get updated. The easiest way to implement this in qemu is to
simply update them whenever we map a TLB translation and act according
to the permissions....

s390x: implement rrbe instruction properly

The rrbe instruction resets the reference bit in the given storage key.
So far, we merely made it a nop and also returned an invalid CC value,
so that the kernel never knew if a page actually got accessed.

This patch implements it properly, flushing the R bit and returning the...

s390x: implement SIGP restart and shutdown

An s390x OS does reboot and shutdown triggers through hypercalls that
we didn't implement on the TCG backend yet. That means that so far we
couldn't shut down virtual machines for example, having them hang on
shutdown when not using KVM....

s390: Fix cpu shutdown for KVM

On s390 a shutdown is the state of all CPUs being either stopped
or disabled (for interrupts) waiting. We have to track the overall
number of running CPUs to call the shutdown sequence accordingly.
This patch implements the counting and shutdown handling for the...

s390x: Add shutdown for TCG s390-virtio machine

Now that we have code in place to do refcounting of online CPUs, we
can drag the TCG code along and implement shutdown for that one too,
so it doesn't feel left out by its KVM counterpart.

softmmu_header: pass CPUState to tlb_fill

Pass CPUState pointer to tlb_fill() instead of architecture local
cpu_single_env hacks.

Use new macro QEMU_PACKED for packed structures

Most changes were made using these commands:

git grep -la '__attribute__((packed))'|xargs perl -pi -e 's/__attribute__\(\(packed\)\)/QEMU_PACKED/'
git grep -la '__attribute__ ((packed))'|xargs perl -pi -e 's/__attribute__ \(\(packed\)\)/QEMU_PACKED/'...

Fix conversions from pointer to tcg_target_long

tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long.

These changes are needed for build environments where...
