ma-mapping fixes for Linux 6.7

 - don't leave pages decrypted for DMA in encrypted memory setups linger
   around on failure (Petr Tesarik)
 - fix an out of bounds access in the new dynamic swiotlb code (Petr Tesarik)
 - fix dma_addressing_limited for systems with weird physical memory layouts
   (Jia He)

----------------------------------------------------------------
Jia He (2):
      dma-mapping: move dma_addressing_limited() out of line
      dma-mapping: fix dma_addressing_limited() if dma_range_map can't cover all system RAM
