Changes for v6:
* CPUTLBEntryFull is now completely reviewed.
* Incorporated the CPUClass caching patches,
as I will add a new use of the cached value.
* Move CPUJumpCache out of include/hw/core.h. While looking at
Alex's review of the patch, I realized that adding the virtual
pc value unconditionally would consume 64kB per cpu on targets
that do not require it. Further, making it dynamically allocated
(a consequence of core.h not having the structure definition to
add to CPUState), means that we save 64kB per cpu when running
with hardware virtualization (kvm, xen, etc).
* Add CPUClass.get_pc, so that we can always use or filter on the
virtual address when logging.
Patches needing review:
13-accel-tcg-Do-not-align-tb-page_addr-0.patch
14-accel-tcg-Inline-tb_flush_jmp_cache.patch (new)
16-hw-core-Add-CPUClass.get_pc.patch (new)
17-accel-tcg-Introduce-tb_pc-and-log_pc.patch (mostly new)
18-accel-tcg-Introduce-TARGET_TB_PCREL.patch
