[PATCH 0/3] xen/privcmd: misc corrections

[Jan Beulich]

The three changes here are largely independent, except for a contextual
dependency between 2 and 3. Note that patch 1 will need actually testing,
on Arm.

1: replace kcalloc() by kvcalloc() when allocating empty pages
2: fix error handling in mmap-resource processing
3: drop "pages" parameter from xen_remap_pfn()
