Marcelo, can you merge the loop-deadlock fix? (the others aren't
trivially mergeable yet and for the tcp conntrack you'd need to ask
Rusty first, the change is simple enough that I merged it for now)

Andrew, could you give it a spin to verify I/O performance is back? It
is fast for me now.

        Not used actively anymore for the coredump (we walk the pagetables
        by hand instead of using the MMU now).

Only in 2.4.17rc1aa1: 00_loop-deadlock-1

        Fixed loop deadlock (balance_dirty() must not be called within the
        request_fn or it can deadlock or recurse way too much). It is
        enough to recall balance_dirty() at the highest layer so this won't
        introduce any stability problem.

Only in 2.4.17rc1aa1: 00_tcp-conntrack-fin-1

        After upgrading my firewall/NAT to 2.4 (s/ipchains/iptables/ :) I started
        getting valid tcp packets dropped/logged (I'm allowing only RELATED and
        ESTABLISHED packets from the outside, with ipchains I was allowing all
        tcp packets that weren't syn and there weren't problems). Rusty sent me
        the above fix to see if my problem with the tcp connection tracking
        goes away (without adding again the rule that all non tcp syn can came in).

Only in 2.4.17pre4aa1: 10_vm-19
Only in 2.4.17rc1aa1: 10_vm-20

        Should fix the I/O async flushing performance drop reported by Andrew.
        Cannot += BUF_LOCKED any longer in balance_dirty because we don't waste
        time any longer refiling clean buffers into the BUF_CLEAN now (sync has to
        pass all over the bh anyways so it doesn't matter for it either).
        Avoid collapsing the max_mapped during shrink_cache internal passes.
