Moving from ipset 2.4.5 to 2.4.7. Upstream changed, but
the Xtables-addons copy did not (issues were not present):
>2.4.7
> - Typo which broke compilation with kernels < 2.6.28
> fixed (reported by Richard Lucassen, Danny Rawlins)
>
>2.4.6
> - Compatibility fix for kernels >= 2.6.28
As of Linux kernel commit 2351ec533ed0dd56052ab96988d2161d5ecc8ed9,
semaphore.h was moved from asm/ to linux/, which breaks building of
ipset. Add compat glue to ip_set.c to fix building on 2.6.27 an
onwards.
