Subject[PATCH] mm/hmm.c: remove redundant variables align_start and align_end
Date
From: Colin Ian King <colin.king@canonical.com>

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]
