[Qemu-devel] [PATCH qom-cpu v6 0/4] target-i386: Clean up DR7 breakpoint handling

["Andreas Färber" <afaerber@suse.de>]

Hello Guang,

Are you okay with this version?

Regards,
Andreas

v5 -> v6:
* Fix bisectability by deferring use of hw_{local,global}_breakpoint_enabled().
* Reword the commit messages for clarity.
* Squash more constant usage into first patch.
* Reorder DATA_RW and DATA_WR to match original switch cases.
* Untangle introduction of breakpoint helper functions from goto/if refactorings.
* Make hw_breakpoint_enabled() return bool.
* Keep IO_RW in place for patch readability.
* Keep reg variable name for patch readability.
* Move {bp,wp}_match inside loop to clarify scope and to avoid double false init.
* Make check_hw_breakpoints() return bool, change force_dr6_update arg to bool.

- fix some not well formated changes.
- split functional and non-functional changes for cherry-picking
suggested by Andreas Färber <afaerber@suse.de>

changes v3->v4:

- fix wrong logic of hw_{global,local}_breakpoint_enabled usage
suggested by Peter Maydell <peter.maydell@linaro.org>

changes v2->v3:

- split hw_breakpoint_enabled into hw_{global,local}_breakpoint_enabled

changes v1->v2:

- add _TYPE_ to the name of dr7 bit field
- fix some coding styles
