[PATCH v4 00/19] Replace PCI pool by DMA pool API

[PATCH v4 00/19] Replace PCI pool by DMA pool API

[Romain Perier]

The current PCI pool API are simple macro functions direct expanded to
the appropriated dma pool functions. The prototypes are almost the same
and semantically, they are very similar. I propose to use the DMA pool
API directly and get rid of the old API.

This set of patches, replaces the old API by the dma pool API, adds
support to warn about this old API in checkpath.pl and remove the
defines.

Changes in v4:
- Rebased series onto next-20170301
- Removed patch 20/20: checks done by checkpath.pl, no longer required.
  Thanks to Peter and Joe for their feedbacks.
- Added Reviewed-by tags

Changes in v3:
- Rebased series onto next-20170224
- Fix checkpath.pl reports for patch 11/20 and patch 12/20
- Remove prefix RFC
Changes in v2:
- Introduced patch 18/20
- Fixed cosmetic changes: spaces before brace, live over 80 characters
- Removed some of the check for NULL pointers before calling dma_pool_destroy
- Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches
- Added Tested-by and Acked-by tags

[PATCH v4 11/19] scsi: megaraid: Replace PCI pool old API

[Romain Perier]

The PCI pool API is deprecated. This commits replaces the PCI pool old
API by the appropriated function with the DMA pool API.

this is the new API that could be used for that purpose.
