Subject: [PATCH 7/7] Finished removing usages of "pci-dma-compat.h" KPI
Im sorry to the kernel maintainers. TLDR; this patch came to early
and I didnt expect to be working on the kernel at 1 am.
https://lkml.org/lkml/2022/2/23/11 deals with much of the reasons
of this commit and part of what should have been included here but
is now included here(ie. this should have been 2 parts). If you
have the time I plead that you commit that, this and another
commit removing pci-dma-compat.h, removing the refrence at pci.h
and replace it with a include to <linux/dma-mapping.h>. If you dont
have the time to do this then I will do it during the next -rc but
make sure it compiles finishes just in case(ive compiled the kernel
3 times to be sure but you never know). If there are any problems
with this patch, tell me and ill send a follow up that will fix the
issues.
