Hello arm-soc maintainers,

Please pull these two patches that optmize how the OP-TEE driver private
shared memory allocated as dynamic shared memory.

Thanks,

  optee: allocate shared memory with alloc_pages_exact() (2023-12-04 14:48:42 +0100)

----------------------------------------------------------------
OP-TEE kernel private shared memory optimizations

Optimize OP-TEE driver private shared memory allocated as dynamic shared
memory. Both to handle larger than one page allocations and for more
efficient memory usage.

----------------------------------------------------------------
Jens Wiklander (2):
      optee: add page list to kernel private shared memory
      optee: allocate shared memory with alloc_pages_exact()
