Linus Torvalds 009fbfc97b Merge tag 'dma-mapping-6.7-2023-10-30' of git://git.infradead.org/users/hch/dma-mapping

Pull dma-mapping updates from Christoph Hellwig:

 - get rid of the fake support for coherent DMA allocation on coldfire
   with caches (Christoph Hellwig)

 - add a few Kconfig dependencies so that Kconfig catches the use of
   invalid configurations (Christoph Hellwig)

 - fix a type in dma-debug output (Chuck Lever)

 - rewrite a comment in swiotlb (Sean Christopherson)
