PATCH 1/1 drivers: staging: lustre: Kconfig: Let LUSTRE_LLITE_LLOOP depend on all !"*_64K*" page

It does not support 64K page, so let it disabled for 64K page under all architectures. The related error (with allmodconfig under tile):

Use "find ./ | grep Kconfig | xargs grep --color 64K" to find all 64K page macros.
