The memory freeing report wasn't very useful for figuring out which parts of the kernel image were being freed. Add the details for clearer reporting in dmesg. Before: Freeing unused kernel image memory: 1348K Write protecting the kernel read-only data: 20480k Freeing unused kernel image memory: 2040K Freeing unused kernel image memory: 172K After: Freeing unused kernel image (initmem) memory: 1348K Write protecting the kernel read-only data: 20480k Freeing unused kernel image (text/rodata gap) memory: 2040K Freeing unused kernel image (rodata/data gap) memory: 172K Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Borislav Petkov <bp@suse.de> Cc: Andy Lutomirski <luto@kernel.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: "H.
