Merge branch 'stable/for-linus-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb
Pull swiotlb updates from Konrad Rzeszutek Wilk:
"A new feature called restricted DMA pools. It allows SWIOTLB to
utilize per-device (or per-platform) allocated memory pools instead of
using the global one.
The first big user of this is ARM Confidential Computing where the
memory for DMA operations can be set per platform"
* 'stable/for-linus-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb: (23 commits)
swiotlb: use depends on for DMA_RESTRICTED_POOL
of: restricted dma: Don't fail device probe on rmem init failure
of: Move of_dma_set_restricted_buffer() into device.c
powerpc/svm: Don't issue ultracalls if !mem_encrypt_active()
s390/pv: fix the forcing of the swiotlb
swiotlb: Free tbl memory in swiotlb_exit()
swiotlb: Emit diagnostic in swiotlb_exit()
swiotlb: Convert io_default_tlb_mem to static allocation
of: Return success from of_dma_set_restricted_buffer() when !OF_ADDRESS
swiotlb: add overflow checks to swiotlb_bounce
swiotlb: fix implicit debugfs declarations
of: Add plumbing for restricted DMA pool
dt-bindings: of: Add restricted DMA pool
swiotlb: Add restricted DMA pool initialization
swiotlb: Add restricted DMA alloc/free support
swiotlb: Refactor swiotlb_tbl_unmap_single
swiotlb: Move alloc_size to swiotlb_find_slots
swiotlb: Use is_swiotlb_force_bounce for swiotlb data bouncing
swiotlb: Update is_swiotlb_active to add a struct device argument
swiotlb: Update is_swiotlb_buffer to add a struct device argument
