mm/io-mapping: precompute remap protection flags for clarity
Patch series "mm: small cleanups for io-mapping, debug_page_alloc and
numa".
This series includes three small cleanups to mm/:
- io-mapping: simplify remap protection flag calculation
- debug_page_alloc: improve error message by printing invalid input
- numa: remove unnecessary variable for clarity
No functional changes.
This patch (of 3):
In io_mapping_map_user(), precompute the page protection flags in a local
variable before calling remap_pfn_range_notrack().
No functional change.
