Pull swiotlb updates from Konrad Rzeszutek Wilk:
"Two memory encryption related patches (SWIOTLB is enabled by default
for AMD-SEV):
- Add support for alignment so that NVME can properly work
- Keep track of requested DMA buffers length, as underlaying hardware
devices can trip SWIOTLB to bounce too much and crash the kernel
And a tiny fix to use proper APIs in drivers"
* 'stable/for-linus-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb:
swiotlb: Validate bounce size in the sync/unmap path
nvme-pci: set min_align_mask
swiotlb: respect min_align_mask
swiotlb: don't modify orig_addr in swiotlb_tbl_sync_single
swiotlb: refactor swiotlb_tbl_map_single
swiotlb: clean up swiotlb_tbl_unmap_single
swiotlb: factor out a nr_slots helper
swiotlb: factor out an io_tlb_offset helper
swiotlb: add a IO_TLB_SIZE define
driver core: add a min_align_mask field to struct device_dma_parameters
sdhci: stop poking into swiotlb internals
