Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there aresome additions and it's not entirely compatible. Because of that, there havebeen conflicts with system headers on BSD systems. Some hacks have beenintroduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896,...

If PVR settings enable illegal insn trap, trap when QEMU finds aninsn it knows nothing about.

microblaze: Correct prio between MMU and unaligned exceptions.
The microblaze gives MMU faults priority. For stores we stillhave a flaw that the value leaks to memory in the case of anunaligned exception.
microblaze: HW Exception fixes.
microblaze: Trap on illegal load/store sizes.
microblaze: Correct FPU decoding masks.
microblaze: Compute masks for alignment checks at translation time.

microblaze: Trap on bus accesses to unmapped areas.
microblaze: MMU shows more respect to synthesis config.
The microblaze MMU can be synthesized in different configurations.Have the MMU model show more respect to the chosen configuration.
microblaze: Trap on unaligned data accesses.
Untested...
microblaze: Trap on divizions by zero.
microblaze: Correct mfs into r0.
microblaze: Catch illegal insns and privilege violations.
Raise illegal instruction exceptions when executing instructions thatrequire units not available on the particulare microblaze configuration.
Also trap priviliege violations made by userspace.
microblaze: Add infrastructure for supporting hw exceptions.
microblaze: Clear exception in dslot ESR bit if not in dslot.
microblaze: Correct MMU debug log.
cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signal
handle_cpu_signal is very nearly copy-paste code for each target, with afew minor variations. This patch sets up appropriate defaults for ageneric handle_cpu_signal and provides overrides for particular targets...

microblaze: Make writes to MMU_ZPR flush the TLB.
microblaze: Correct typo.
microblaze: Add petalogix s3a1800dsp MMU linux ref-design.
This setup was designed by petalogix and is supported by upstream linux.The design targets a xilinx spartan-3a-1800 dsp board with MMU.
microblaze: Add MMU emulation.
microblaze: Add translation routines.
