Subject: [PATCH v3 00/28] ARM MMU code improvements and on-demand PTE allocation
Date: Thu, 17 May 2018 13:58:09 -0700 [thread overview]
Message-ID: <20180517205837.32421-1-andrew.smirnov@gmail.com> (raw)
Everyone:
With exeception of patch 27/28, all patches in this series are just
small improvements(IMHO) that I made while working with ARM MMU code.
Patch 27/28, OTOH, brings a bit of a change to how MMU code allocates
PTEs, postponing that until the users of DMA API actually request
that.
Feedback is welcome!
Changes since [v2]:
- Dropped create_sections() macro.
- Fixed a bug in 6/28, pointed out by Sam
- Minor style changes and comment re-wording
Changes since [v1]:
- create_sections() reworked to keep all of its arguments
32-bits
- Fixed compliation error in 9/28
- Small style fix for 26/28
- Collected Reviewed-by's from Lucas
