Subject: [PATCH 0/4] Remove get_kernel_pages()
Date: Sat, 1 Oct 2022 17:23:22 -0700 [thread overview]
Message-ID: <20221002002326.946620-1-ira.weiny@intel.com> (raw)
From: Ira Weiny <ira.weiny@intel.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()
