I put it in linux-next and devel/for-linus-5.15.

I will wait a day and see if there are any issues with linux-next and if
not will send out a GIT pull.

Thanks!

[PATCH] swiotlb: use depends on for DMA_RESTRICTED_POOL

2021-08-26 Thread Claire Chang 
Use depends on instead of select for DMA_RESTRICTED_POOL; otherwise it
will make SWIOTLB user configurable and cause compile errors for some
arch (e.g. mips).

Fixes: 0b84e4f8b793 ("swiotlb: Add restricted DMA pool initialization")

  This enables support for restricted DMA pools which provide a level of
  DMA memory protection on systems with limited hardware protection
