The 64k pages patch changed the meaning of one argument passed to the
low level hash functions (from "large" it became "psize" or page size
index), but one of the call sites wasn't properly updated, causing
potential random weird problems with huge pages. This fixes it.

This bug exists in the current code and prevents machines from booting

Workaround is to boot with 'numa=off'. Looks like a simple typo.

ppc: Build in all three of powermac, PREP and CHRP support
This reverts commit da0825fd201a03294dbf7f8f030676d608da122c, making
it so that if you select CONFIG_PPC_MULTIPLATFORM you get support
for PMAC, PREP and CHRP built in.
The reason for not allowing PMAC, PREP and CHRP to be selected
individually for ARCH=ppc is that there is too much interdependency
between them in the platform support code. For example, CHRP uses
the PMAC nvram code.
Configuring with ARCH=powerpc does allow you to select support for
PMAC and CHRP separately. Support for PREP is not there yet but
should be there soon.

powerpc/pseries: Optimize IOMMU setup
The previous commit will use the page-at-a-time hypervisor call for

one 64k page, even though that means 16 calls to the hypervisor, since
the hypervisor still works on 4k pages. This optimizes this case by

[NETFILTER]: Fix recent match jiffies wrap mismatches
Around jiffies wrap time (i.e. within first 5 mins after boot), recent
match rules which contain both --seconds and --hitcount arguments
experience false matches.
This is because the last_pkts array is filled with zeros on creation, and
when comparing 'now' to 0 (+ --seconds argument), time_before_eq thinks it
has found a hit.
Below patch adds a break if the packet value is zero. This has the
unfortunate side effect of causing mismatches if a packet was received
when jiffies really was equal to zero. The odds of that happening are
slim compared to the problems caused by not adding the break however.
Plus, the author used this same method just below, so it is "good enough".

[NETFILTER]: Ignore ACKs ACKs on half open connections in TCP conntrack
Mounting NFS file systems after a (warm) reboot could take a long time if
firewalling and connection tracking was enabled.
The reason is that the NFS clients tends to use the same ports (800 and
counting down). Now on reboot, the server would still have a TCB for an
existing TCP connection client:800 -> server:2049. The client sends a
SYN from port 800 to server:2049, which elicits an ACK from the server.
The firewall on the client drops the ACK because (from its point of
view) the connection is still in half-open state, and it expects to see
a SYNACK.
The client will eventually time out after several minutes.
The following patch corrects this, by accepting ACKs on half open
connections as well.

Currently, when we stop TX/RX channels we just do some number of loops
without relying on actual spent time. This has finally bitten me on
one of our systems (heavy network traffic during start up, RX channel
is stopped several times to configure multicast list).
Graceful channel stop can take up to 1 frame time, so I've added
device specific timeout counter which depends on current link speed
and calls to udelay() to really wait required amount of time before
giving up.
