[Impact]

Previously, Google requested a set of IRDMA patches to be applied to the 
Resolute gcp kernel. Now, the request is to backport two follow-up commits 
to fix 3aa31a8bb11e ("dma-buf: provide phys_vec to scatter-gather mapping 
routine").

[Fix]

Target patches:
  b344ca94e8cc8 ("dma-buf: Fix silent overflow for phys vec to sgt")
  06dd5e1ae8ce4 ("dma-buf: Split sgl by largest page-aligned chunk")

Both applied cleanly.

[Test Plan]

Compiled and boot tested

[Regression potential]

This has low potential for regression because the commits applied cleanly, 
and only the two target patches were required.
