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/20180714161124.3923-1-colin.king@canonical.com Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
