Disable syscalls sys32_iopl() and sys32_ioperm() on ia64.
To emulate these 2 syscalls correctly, we need to guarantee uncached
memory attributes on ia64, which is difficult. The only user of this
interface that we know of is X. So we think it's better to disable it.

[IPV4]: Zap CONFIG_IP_ROUTE_TOS
These facilities are now available by default.
The config option makes no sense because:
1) It makes no change to the layout of any
data structure, therefore it has no impact
upon memory usage of the routing tables.
2) It makes no significant change to code size,
only a handfull of lookup comparisons are
protected by the option.
3) It is needed for full RFC1812 compliance anyways.

[PATCH] Warn that ipchains and ipfwadm are going away
At the recent netfilter workshop in Erlangen, we was decided to remove
the backwards compatibility code for ipchains and ipfwadm. This will
allow significant cleanup of interfaces, since we had to have a
mid-level interface for the backwards compatibility layer to use.
Start off with a warning for 2.6.9, so any remaining users have a chance
to migrate. Their firewall scripts might not check return values, and
they might get a nasty surprise when this goes away.
Linus removed the "volatile" statement from the definition of the
__raw_* IO accessors on ppc64, which cause some real bad optisations to
happen in some fbdev's like matroxfb to happen (just imagine that
matroxfb loops reading an IO register waiting for a bit to change).
The __raw_xxxx() functions still want ordered accesses (they avoid the
byteswap, though)

The previous change is not the whole story - the mmc queue
thread may be handling a request. We must wait for outstanding
requests to complete before allowing the suspend to proceed,
otherwise we may suffer loss of data.

[PATCH] r8169: default on disabling PCIDAC
Default to disabling PCI DAC as this option appears unsafe on amd64
(original suggestion by Hans-Frieder Vogt <hfvogt@arcor.de>).
The driver will typically report PCI System error when something goes
wrong. The relevant interrupt is not masked any more and the driver
can thus be disabled.

[MMC] Clean up MMC card CID/CSD decoding, stage 1.
Now that the raw CSD and CID information are available in mmc_card,
there's little point not passing the mmc_card structure into the
decode functions themselves.
This will be necessary, since there's several different formats of
CID decode, and the format appears to depend on data in the CSD.
If we are unable to decode the CID or CSD, we can mark the card bad
and refuse to bind it to any drivers. Users can then retrieve the
raw undecoded CID and CSD from sysfs for debugging purposes.
