This series address two related issues in scatter-gather mapping,
specifically for the MMIO based dma-buf mapping. The fixes ensure
sgt mapping is correct, and proper for large MMIO regions.

Patch 1 fixes a silent integer overflow for mapping length exceeding 4G
(Previously submitted as [PATCH v7] dma-buf: Fix silent overflow for
phys vec to sgt)
https://lore.kernel.org/all/20260609164047.486227-1-xuehaohu@google.com/

Patch 2 Splits sgl by largest page aligned chunk
(Previously submitted as [PATCH v3] dma-buf: Split sgl by largest page-aligned chunk)
https://lore.kernel.org/all/20260722233806.3922093-1-dhu@x6u.co/

Changes in v8:
 - Combined the two patches into one unified series to avoid merge
   conflicts.
 - Collected Reviewed-by tag from Leon Romanovsky for Patch 2.
