Subject: [PATCH] udp: calculate udp_mem based on low memory instead of all
 memory

While working on UDP, I found a comment in udp_init() was outdated.

This patch could help some 32bit machines, and restore comment validity :)

No hurry, so I based it on top of my previous patch (net-next-2.6)

Thanks

[PATCH] udp: calculate udp_mem based on low memory instead of all memory

This patch mimics commit 57413ebc4e0f1e471a3b4db4aff9a85c083d090e
(tcp: calculate tcp_mem based on low memory instead of all memory)

The udp_mem array which contains limits on the total amount of memory
used by UDP sockets is calculated based on nr_all_pages.  On a 32 bits
x86 system, we should base this on the number of lowmem pages.
