Hi
Changes since v1:
- Add reviewed tags for reviewed patches
- Change comment about last_stage (philmd)
- Change cast to 1ULL for ram_release_page()
- remove TARGET_PAGE_MASK mask. It was used only for compression,
and offset should be page aligned already
Please, review.
Thanks, Juan.
[v1]
This series do several cleanups:
- Dave found that I was using "%d" for unsigned, fix all uses.
- We pass last_stage left and right, but we only use it in two places
Just move it to RAMState.
- do_compress_page() used a goto when not needed.
- ram_release_pages() was always used with one page
- And put it when we detect zero pages, instead of everywhere we have find a
zero page.
Please, review.
