Hi,
This is fifth approach for replacing struct dma_attrs with unsigned
long.
The main patch (1/44) doing the change is split into many subpatches
for easier review (2-42). They should be squashed together when
applying.
Rebased on v4.7-rc5.
For easier testing the patchset is available here:
repo: https://github.com/krzk/linux
branch: for-next/dma-attrs-const-v5
Changes since v4
================
1. Collect some acks. Still need more.
2. Minor fixes pointed by Robin Murphy.
3. Applied changes from Bart Van Assche's comment.
4. More tests and builds (using https://www.kernel.org/pub/tools/crosstool/).
Changes since v3
================
1. Collect some acks.
2. Drop wrong patch 1/45 ("powerpc: dma-mapping: Don't hard-code
the value of DMA_ATTR_WEAK_ORDERING").
3. Minor fix pointed out by Michael Ellerman.
Changes since v2
================
1. Follow Christoph Hellwig's comments (don't use BIT add
documentation, remove dma_get_attr).
Rationale
=========
The dma-mapping core and the implementations do not change the
DMA attributes passed by pointer. Thus the pointer can point to const
data. However the attributes do not have to be a bitfield. Instead
unsigned long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.
Best regards,
Krzysztof

For all the drm driver patches:
Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>
Should I pull these in through drm-misc, or do you prefer to merge them
through a special topic branch (with everything else) instead on your own?
