786a4ea82e Convert (ffs(val) - 1) to ctz32(val)
This commit was generated mechanically by coccinelle from the following
semantic patch:

@@
expression val;
@@
- (ffs(val) - 1)
+ ctz32(val)

The call sites have been audited to ensure the ffs(0) - 1 == -1 case
never occurs (due to input validation, asserts, etc).  Therefore we
don't need to worry about the fact that ctz32(0) == 32.

166fa99996 hw/arm/pxa2xx_gpio: Correct and register vmstate
The pxa2xx-gpio device has a VMStateDescription, but it was accidentally
never actually registered, and it wasn't quite correct. Remove the
'lines' field (this is a device property, not mutable state), add the
missing 'prev_level' field, and set dc->vmsd so it actually gets used.

ab7a0f0b6d hw/arm/pxa2xx_gpio: Fix handling of GPSR/GPCR reads
The PXA2xx GPIO GPSR and GPCR registers are write-only, with reads being
undefined behaviour. Instead of having GPCR return 31337 and GPSR return
the value last written, make both log the guest error and return 0.

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.

0d09e41a51 hw: move headers to include/
Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

259186a7d2 cpu: Move halted and interrupt_request fields to CPUState
Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

Pass PowerPCCPU to kvmppc_handle_halt().
