mm/hmm.c: remove unused variables align_start and align_end

Variables align_start and align_end are being assigned but are never used hence they are redundant and can be removed. Cleans up clang warnings: warning: variable 'align_start' set but not used [-Wunused-but-set-variable] warning: variable 'align_size' set but not used [-Wunused-but-set-variable] Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Colin Ian King <[email protected]> Reviewed-by: Andrew Morton <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
