[PATCH v8 0/19] enable swiotlb-xen on arm and arm64
...xen on arm and arm64;
- call __set_phys_to_machine_multi from xen_create_contiguous_region to
update the p2m;
- remove XENMEM_unpin and XENMEM_exchange_and_pin;
- set nr_exchanged to 0 before calling the hypercall;

[RFC v3 00/45] dma-mapping: Use unsigned long for dma_attrs
Hi,
This is third approach (complete this time) for replacing struct
dma_attrs with unsigned long.
The main patch (2/45) doing the change is split into many subpatches
for easier review (3-43). They should be squashed together when
applying.
*Important:* Patchset is *only* build tested on allyesconfigs: ARM,
ARM64, i386, x86_64 and powerpc. Please provide reviewes and tests
for other
