Linus Torvalds d644c670ef Remove get_kernel_pages() 
Vmalloc page support is removed from shm_get_kernel_pages() and the
 get_kernel_pages() call is replaced by calls to get_page(). With no
 remaining callers of get_kernel_pages() the function is removed.

Merge tag 'remove-get_kernel_pages-for-6.3' of https://git.linaro.org/people/jens.wiklander/linux-tee

Pull TEE update from Jens Wiklander:
 "Remove get_kernel_pages()

  Vmalloc page support is removed from shm_get_kernel_pages() and the
  get_kernel_pages() call is replaced by calls to get_page(). With no
  remaining callers of get_kernel_pages() the function is removed"

[ This looks like it's just some random 'tee' cleanup, but the bigger
  picture impetus for this is really to to to remove historical
  confusion with mixed use of kernel virtual addresses and 'struct page'
  pointers.

  Kernel virtual pointers in the vmalloc space is then particularly
  confusing - both for looking up a page pointer (when trying to then
  unify a "virtual address or page" interface) and _particularly_ when
  mixed with HIGHMEM support and the kmap*() family of remapping.

  This is particularly true with HIGHMEM getting much less test coverage
  with 32-bit architectures being increasingly legacy targets.

  So we actively wanted to remove get_kernel_pages() to make sure nobody
  else used it too, and thus the 'tee' part is "finally remove last
  user".

  See also commit 6647e76ab6 ("v4l2: don't fall back to follow_pfn()
  if pin_user_pages_fast() fails") for a totally different version of a
  conceptually similar "let's stop this confusion of different ways of
  referring to memory".   - Linus ]
