Subject: [PATCH v2 00/28] ARM MMU code improvements and on-demand PTE allocation
Date: Wed, 16 May 2018 13:00:08 -0700	[thread overview]
Message-ID: <20180516200036.29829-1-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 [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

[v1] http://lists.infradead.org/pipermail/barebox/2018-May/032816.html
