[Qemu-devel] [PATCH v2 00/17] tcg: tb_lock_removal redux v2

[Emilio G. Cota]

v1: http://lists.gnu.org/archive/html/qemu-devel/2018-02/msg06499.html

Changes since v1:

- Add R-b's

- Rebase onto master

- qht_lookup_custom: move @func to be the last argument, which
  simplifies the new qht_lookup function. (I've kept R-b's tags
  here because this is a very simple change.)

- qht_insert: add an **existing argument and keep the bool return value,
  as suggested by Alex.

- Fix indentation of TB_FOR_EACH_TAGGED macro

- Add page_locked assertions, as suggested by Alex.

- Expand comment in tb_link_page and in docs/mttcg about parallel
  code insertion.

- Fix stale comment about tb_lock next to CF_INVALID

- Fix stale comment in cpu_restore_state, as suggested by Alex.

There is only one checkpatch error for the entire series -- it is
a false positive.
