Subject: [PATCH] kmemleak: config-options: Default buffer size for kmemleak

If we try to find the memory leaks in kernel that is
compiled with 'make defconfig', the default buffer size
of DEBUG_KMEMLEAK_EARLY_LOG_SIZE seem to be inadequate.

Change the buffer size from 400 to 1000,
which is sufficient for most cases.

Thanks to Pekka Enberg's comments on my previous mail, I am sending a better patch,
and adding new reviewers as suggested by the get_maintainer script.
