This patch changes the generic_defconfig so it works on all sn2
platforms I have access to. There is only one support configuration
which was not tested and that configuration is only a combination of two
tested configurations. With this patchset applied, a generic kernel can
be booted on either a RHEL 5.2, RHEL5.3, or SLES10 SP1 root and operate.
All features needed by SGI's ProPack are also working. I have not
tested all features of RHEL or SLES, but they do at least boot.

Newfile: arch/sh/include/cpu-sh2a/cpu/addrspace.h
This file seems had be removed to use fallback (cpu-common/cpu/addrspace.h),
but, I'd like to add sh2a specific file here, because
1. the values defined there are not suitable for sh2a.
2. I don't think there is "common" definition for these values.
Values are chosen by consideration of followings...
P1 is 0. perhaps no question.
P2 is from hardware manual, which says no-cache area starts at 20000000.
It means that P? space size=20000000.
P3 is P2+size since asm/ptrace.h uses P3 as a end of P2.
P4 is P3+size since asm/fixup.h uses P4 as a end of P3.

The old code will drop IPv6 packet if ipfragok is not set, since
ipfragok is obsoleted, will be instead by used skb->local_df, so this
check must be changed to skb->local_df.
This patch fix this problem and not drop packet if skb->local_df is
set to true.

The ipfragok flag controls whether the packet may be fragmented
either on the local host on beyond. The latter is only valid on
IPv4.
In fact, we never want to do the latter even on IPv4 when PMTU is
enabled. This is because even though we can't fragment packets
within SCTP due to the prtocol's inherent faults, we can still
fragment it at IP layer. By setting the DF bit we will improve
the PMTU process.
RFC 2960 only says that we SHOULD clear the DF bit in this case,
so we're compliant even if we set the DF bit. In fact RFC 4960
no longer has this statement.
Once we make this change, we only need to control the local
fragmentation. There is already a bit in the skb which controls
that, local_df. So this patch sets that instead of using the
ipfragok argument.
The only complication is that there isn't a struct sock object
per transport, so for IPv4 we have to resort to changing the
pmtudisc field for every packet. This should be safe though
as the protocol is single-threaded.
Note that after this patch we can remove ipfragok from the rest
of the stack too.

ip_default_ttl ctl_table, but it is never set to a meaningful

rt_cache_invalidate(). Set extra2 to init_net, to avoid that.

If a netdevice does not support hardware GSO, allowing the stack to
use GSO anyway and then splitting the GSO skb into MSS-sized pieces
as it is handed to the netdevice for transmitting is likely still
a win as far as throughput and/or CPU usage are concerned, since it
reduces the number of trips through the output path.
This patch enables the use of GSO on any netdevice that supports SG.
If a GSO skb is then sent to a netdevice that supports SG but does not
support hardware GSO, net/core/dev.c:dev_hard_start_xmit() will take
care of doing the necessary GSO segmentation in software.

When pneigh entries exist, but the user's read buffer isn't sufficient to
hold them all, one of the pneigh entries will be missing from the results.
In neigh_get_idx_any, the number of elements which neigh_get_idx
encountered is not correctly subtracted from the position number before
the call to pneigh_get_idx. neigh_get_idx reduces the position by 1 for
each call to neigh_get_next, but it does not reduce it by one for the
first element (neigh_get_first). The patch alters the neigh_get_idx and
pneigh_get_idx functions to subtract one from pos, for the first element,
when pos is non-zero.

Recently, a bug having to do with the alignment of transaction response
data was fixed. However, some apps such as libdc1394 relied on the
presence of that bug in order to function correctly. In order to stay
compatible with old versions of those apps, this patch preserves the bug
in cases where it is harmless to normal operation (such as the single
quadlet read) due to a simple duplication of data. This guarantees
maximum compatability for those users who are using the old app with the
fixed kernel.
