Subject: [PATCH 0/4] Remove get_kernel_pages()

From: Ira Weiny <ira.weiny@...el.com>

get_kernel_pages() only had one caller [shm_get_kernel_pages()] which did not
need the functionality it provided.  Furthermore, it called kmap_to_page()
which we are looking to removed.

Alter shm_get_kernel_pages() to no longer call get_kernel_pages() and remove
get_kernel_pages().  Along the way it was noted that shm_get_kernel_pages()
does not have any need to support vmalloc'ed addresses either.  Remove that
functionality to clean up the logic.

This series also fixes and uses is_kmap_addr().

Ira Weiny (4):
  highmem: Enhance is_kmap_addr() to check kmap_local_page() mappings
  tee: Remove vmalloc page support
  tee: Remove call to get_kernel_pages()
  mm: Remove get_kernel_pages()
