[PATCH v6 00/18] tcg: CPUTLBEntryFull and TARGET_TB_PCREL

[Richard Henderson]

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
