[PATCH 0/8] Start replacing target_ulong with vaddr

[Anton Johansson via <qemu-devel@nongnu.org>]

This is a first patchset in removing target_ulong from non-target/
directories.  As use of target_ulong is spread accross the codebase we
are attempting to target as few maintainers as possible with each
patchset in order to ease reviewing.

The following instances of target_ulong remain in accel/ and tcg/
    - atomic helpers (atomic_common.c.inc), cpu_atomic_*()
      (atomic_template.h,) and cpu_[st|ld]*()
      (cputlb.c/ldst_common.c.inc) are only used in target/ and can
      be pulled out into a separate target-specific file;

    - Calls to cpu_get_tb_cpu_state() cast pc and cs_base to
      target_ulong in order to avoid having to touch the target/
      directory in this patchset;

    - walk_memory_regions() is used in user-exec.c and
      linux-user/elfload.c;

    - helper_ret_*_mmu() is used in tcg/*/tcg-target.c.inc and
      tcg/tci.c;

    - Functions in translate-all.c dealing with TCGContext.gen_insn_data
      will be switched off target_ulong once gen_insn_data and
      TARGET_INSN_START_WORDS have been dealt with;

    - kvm_find_sw_breakpoint() in kvm-all.c used in target/;

    - The last address when looking up page flags for an interval
      [start,last] in pageflags_find()/pageflags_next() is still
      target_long.  I'm not sure why this is required.  This only
      seems relevant on 32-bit guests since the addresses passed
      to the interval tree are uint64_t's, are we relying on a
      sign extension here for some reason?

    - CPUTLBEntry and functions that read from it will be left for a
      later date;

Smaller patchsets implementing above changes will follow.

Finally, the grand goal is to allow for heterogeneous QEMU binaries
consisting of multiple frontends.
