Subject: [PATCH] netfilter: xt_hashlimit: Add missing ULL suffixes for 64-bit constants

On 32-bit (e.g. with m68k-linux-gnu-gcc-4.1):

    net/netfilter/xt_hashlimit.c:476: warning: integer constant is too large for ‘long’ type

    net/netfilter/xt_hashlimit.c: In function ‘rateinfo_recalc’:
    net/netfilter/xt_hashlimit.c:513: warning: integer constant is too large for ‘long’ type
