Merge branch 'stable/for-linus-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb
Pull swiotlb updates from Konrad Rzeszutek Wilk: "Christoph Hellwig has taken a cleaver and trimmed off the not-needed code and nicely folded duplicate code in the generic framework. This lays the groundwork for more work to add extra DMA-backend-ish in the future. Along with that some bug-fixes to make this a nice working package" * 'stable/for-linus-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb: swiotlb: don't override user specified size in swiotlb_adjust_size swiotlb: Fix the type of index swiotlb: Make SWIOTLB_NO_FORCE perform no allocation ARM: Qualify enabling of swiotlb_init() swiotlb: remove swiotlb_nr_tbl swiotlb: dynamically allocate io_tlb_default_mem swiotlb: move global variables into a new io_tlb_mem structure xen-swiotlb: remove the unused size argument from xen_swiotlb_fixup xen-swiotlb: split xen_swiotlb_init swiotlb: lift the double initialization protection from xen-swiotlb xen-swiotlb: remove xen_io_tlb_start and xen_io_tlb_nslabs xen-swiotlb: remove xen_set_nslabs xen-swiotlb: use io_tlb_end in xen_swiotlb_dma_supported xen-swiotlb: use is_swiotlb_buffer in is_xen_swiotlb_buffer swiotlb: split swiotlb_tbl_sync_single swiotlb: move orig addr and size validation into swiotlb_bounce swiotlb: remove the alloc_size parameter to swiotlb_tbl_unmap_single powerpc/svm: stop using io_tlb_start
