[PATCH] PCI: Remove the deprecated "pci-dma-compat.h" API

[PATCH] PCI: Remove the deprecated "pci-dma-compat.h" API

[Christophe JAILLET]

Now that all usages of the functions defined in "pci-dma-compat.h" have
been removed, it is time to remove this file as well.

In order not to break builds, move the "#include <linux/dma-mapping.h>"
that was in "pci-dma-compat.h" into "include/linux/pci.h"

[Christoph Hellwig]

Thanks.  Given that it depends on a few different trees I plan to send
this to Linus after -rc1.

As of 1db333d9a51f ("Merge tag 'spi-fix-v5.17-rc7' of
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi"), all the
following still appear to be used:

  git grep -E "\<PCI_DMA_(BIDIRECTIONAL|TODEVICE|FROMDEVICE|NONE)"
  git grep -E "pci_(alloc|zalloc|free)_consistent"
  git grep -E "pci_(map|unmap)_single"

  git grep -E "pci_(map|unmap)_sg"
  git grep -E "pci_dma_sync_"

Christoph mentioned several other trees that this depends on, and
those would likely be in linux-next, but not yet in Linus' tree.  The
above poking around is from the tip of Linus' tree, which was the
wrong place for me to look.

But I did the same in current linux-next, 71941773e143 ("Add
linux-next specific files for 20220310"), and still found quite a few
uses.  Some are in comments, printks, coccinelle scripts, etc.  I
would assume we'd want to remove them all?

I'm not sure there is much of a point to clean up the historic
comments, but it would be a nice cleanup.  I'd very much like to
queue up this patch now that all the actual symbol references
are gone now.  Are you ok with that?

Yep, I'm OK with that.  I *would* like to see at least
Documentation/PCI/pci.rst updated soonish (it still refers to
pci_set_dma_mask() and friends).
