7d983531c6 Revert "iotests: Use configured python"
This reverts commit f915db07ef.

This commit is broken because it does not account for the
build tree and the source tree being different, and can cause
build failures for out-of-tree builds. Revert it until we can
identify a better solution to the problem.

a9171c4fb5 hw/net/stellaris_enet: Correctly implement the TR and THR registers
Packet transmission for the stellaris ethernet controller can be triggered
in one of two ways:
 * by setting a threshold value in the THR register; when the FIFO
   fill level reaches the threshold, the h/w starts transmitting.
   Software has to finish filling the FIFO before the transmit
   process completes to avoid a (silent) underrun
 * by software writing to the TR register to explicitly trigger
   transmission

Since QEMU transmits packets instantaneously (from the guest's
point of view), implement "transmit based on threshold" with
our existing mechanism of "transmit as soon as we have the whole
packet", with the additional wrinkle that we don't transmit if
the packet size is below the specified threshold, and implement
"transmit by specific request" properly.

The datasheet is clear that the frame length written to the DATA
register is actually stored in the TX FIFO; this means we don't
need to keep both tx_frame_len and tx_fifo_len state separately.

7fd5f064d1 hw/net/stellaris_enet: Correct handling of packet padding
The PADEN bit in the transmit control register enables padding of short
data packets out to the required minimum length. However a typo here
meant we were adjusting tx_fifo_len rather than tx_frame_len, so the
padding didn't actually happen. Fix this bug.

5c10495ab1 hw/net/stellaris_enet: Restructure tx_fifo code to avoid buffer overrun
The current tx_fifo code has a corner case where the guest can overrun
the fifo buffer: if automatic CRCs are disabled we allow the guest to write
the CRC word even if there isn't actually space for it in the FIFO.
The datasheet is unclear about exactly how the hardware deals with this
situation; the most plausible answer seems to be that the CRC word is
just lost.

Implement this fix by separating the "can we stuff another word in the
FIFO" logic from the "should we transmit the packet now" check. This
also moves us closer to the real hardware, which has a number of ways
it can be configured to trigger sending the packet, some of which we
don't implement.

8f1e884b38 savevm: Remove all the unneeded version_minimum_id_old (arm)
After commit 767adce2d, they are redundant.  This way we don't assign them
except when needed.  Once there, there were lots of cases where the ".fields"
indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (apart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

Commit e586822a5 broke the bsd-user build when it removed the
CONFIG_UNAME_RELEASE define but forgot to remove the use of it
in bsd-user. Fix this in the simplest possible way (bsd-user
doesn't make any use at all of the qemu_uname_release variable
except to allow it to be pointlessly set by the user, so this
is all we need to do.)

4700a316df pc: port 92 reset requires a low->high transition
The PIIX datasheet says that "before another INIT pulse can be
generated via [port 92h], [bit 0] must be written back to a
zero.

This bug is masked right now because a full reset will clear the
value of port 92h.  But once we implement soft reset correctly,
the next attempt to enable the A20 line by setting bit 1 (and
leaving the others untouched) will cause another reset.

4a92a558f4 cpu: make CPU_INTERRUPT_RESET available on all targets
On the x86, some devices need access to the CPU reset pin (INIT#).
Provide a generic service to do this, using one of the internal
cpu_interrupt targets.  Generalize the PPC-specific code for
CPU_INTERRUPT_RESET to other targets.

Since PPC does not support migration across QEMU versions (its
machine types are not versioned yet), I picked the value that
is used on x86, CPU_INTERRUPT_TGT_INT_1.  Consequently, TGT_INT_2
and TGT_INT_3 are shifted down by one while keeping their value.

43175fa96a target-i386: preserve FPU and MSR state on INIT
Most MSRs, plus the FPU, MMX, MXCSR, XMM and YMM registers should not
be zeroed on INIT (Table 9-1 in the Intel SDM).  Copy them out of
CPUX86State and back in, instead of special casing env->pat.

The relevant fields are already consecutive except PAT and SMBASE.
However:

- KVM and Hyper-V MSRs should be reset because they include memory
locations written by the hypervisor.  These MSRs are moved together
at the end of the preserved area.

- SVM state can be moved out of the way since it is written by VMRUN.

XCR0 should be reset to 1.

50a2c6e55f kvm: reset state from the CPU's reset method
Now that we have a CPU object with a reset method, it is better to
keep the KVM reset close to the CPU reset.  Using qemu_register_reset
as we do now keeps them far apart.

With this patch, PPC no longer calls the kvm_arch_ function, so
it can get removed there.  Other arches call it from their CPU
reset handler, and the function gets an ARMCPU/X86CPU/S390CPU.

Note that ARM- and s390-specific functions are called kvm_arm_*
and kvm_s390_*, while x86-specific functions are called kvm_arch_*.
That follows the convention used by the different architectures.
Changing that is the topic of a separate patch.

7848c8d19f target-i386: the x86 CPL is stored in CS.selector - auto update hflags accordingly.
Instead of manually calling cpu_x86_set_cpl() when the CPL changes,
check for CPL changes on calls to cpu_x86_load_seg_cache(R_CS).  Every
location that called cpu_x86_set_cpl() also called
cpu_x86_load_seg_cache(R_CS), so cpu_x86_set_cpl() is no longer
required.

This fixes the SMM handler code as it was not setting/restoring the
CPL level manually.
