[PATCH v2 0/2] Mapping an entire folio

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

I had intended to write and test one user before sending this out,
but Dave Howells says he has a user now that wants this functionality,
so here we go.  It is only compile tested.

Earlier thread on this: https://lore.kernel.org/all/YvvdFrtiW33UOkGr@casper.infradead.org/

v2:
 - Remove spurious blank line change in highmem.h (David Howells)
 - Insert missing "else" in folio_unmap_local() (Hyeonggon Yoo)
 - Use vm_unmap_ram() instead of vunmap() in folio_unmap_local() (Hyeonggon Yoo)
 - Factor vmap_alloc() out of vm_map_ram() (Uladzislau Rezki)

Matthew Wilcox (Oracle) (2):
  vmalloc: Factor vmap_alloc() out of vm_map_ram()
  mm: Add folio_map_local()
