[PATCH 0/4] Remove get_kernel_pages()

From: ira . weiny
Date: Sat Oct 01 2022 - 20:23:36 EST

From: Ira Weiny <ira.weiny@xxxxxxxxx>

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()
