Still keep this function because directly using dev->dma_io_tlb_mem
will cause issues for memory allocation for existing devices. The pool
can't support atomic coherent allocation so we need to distinguish the
per device pool and the default pool in swiotlb_alloc.
I didn't move this to a separate file because I feel it might be
confusing for swiotlb_alloc/free (and need more functions to be
non-static).
Maybe instead of moving to a separate file, we can try to come up with
a better naming?
If a device is not behind an IOMMU, we look up the device node and set
up the restricted DMA when the restricted-dma-pool is presented.

Change the default PPR to userspace to 4 (medium), matching the
normal kernel PPR.
This allows system calls and user interrupts to avoid setting PPR on
entry and exit, providing a significant speedup.
This is a change to the user environment.
POWER9 and POWER10 asynchronous machine checks due to stores have their
cause reported in SRR1 but SRR1[42] is set, which in other cases
indicates DSISR cause.
Check for these cases and clear SRR1[42], so the cause matching uses
