In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896,
f40d753718c72693c5f520f0d9899f6e50395e94,
96555a96d724016e13190b28cffa3bc929ac60dc and
3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile.
Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

cpu_synchronize_state() is a little unreadable since the 'modified'
argument isn't self-explanatory. Simplify it by making it always
synchronize the kernel state into qemu, and automatically flush the
registers back to the kernel if they've been synchronized on this
exit.

handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations. This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently. Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.
Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality. I have removed
such blocks for the appropriate targets in this patch.

We do this so we can check on the corresponding stc{w,d}x. whether the

We need to tell the kernel about some initial CPU state we don't have yet,
so let's use the "sregs" IOCTL for that and simply put the Processor Version
Register in there.
Now the kernel knows which guest CPU to virtualize.

According to PPC440 user manual, PPC 440 supports ``mftb'' even it's a
preserved instruction:
PPC440_UM2013.pdf, p.445, table A-3
when I compile a kernel (2.6.30, bamboo_defconfig/440EP &
canyonlands/460EX), I can see ``mftb'' by using ppc-xxx-objdump
vmlinux
I have also checked the ppc 440x[456], 460S, 464, they also should support mftb.
The following patch enable mftb for all ppc 440 variants, including:
440EP, 440GP, 440x4, 440x5 and 460

For 32-bit PPC targets, we translated:
evmergelo rX, rX, rY
as:
rX-lo = rY-lo
rX-hi = rX-lo
which is wrong, because we should be transferring rX-lo first. This
problem is fixed by swapping the order in which we write the parts of
rX.
Similarly, we translated:
evmergelohi rX, rX, rY
as:
rX-lo = rY-hi
rX-hi = rX-lo
In this case, we can't swap the assignment statements, because that
would just cause problems for:
evmergelohi rX, rY, rX
Instead, we detect the first case and save rX-lo in a temporary
variable:
tmp = rX-lo
rX-lo = rY-hi
rX-hi = tmp
These problems don't occur on PPC64 targets because we don't split the
SPE registers into hi/lo parts for such targets.

Access to the PVR SPR is normally forbidden from userspace apps. The
Linux kernel, however, fixes up reads in the appropriate trap handler.
To permit applications that read PVR to run on QEMU, then, we need to
implement the same handling of PVR reads.

This patch adds the missing hooks to allow live migration in KVM mode.
It adds proper synchronization before/after saving/restoring the VCPU
states (note: PPC is untested), hooks into
cpu_physical_memory_set_dirty_tracking() to enable dirty memory logging
at KVM level, and synchronizes that drity log into QEMU's view before
running ram_live_save().

The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.
Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.
Big/Little endian is not handled because devices should not know or care
about this to start with.

According to 604eUM_book (see 8.3.3 Reset inputs p8-54), the IP bit is set
for hreset and the vector is at offset 0x100 from the exception prefix.
