Use valid values for ICH8 map_db. With the old values, when the
controller was in Native mode, and SCC was 1 (drives configured for
IDE), any drive plugged into a slave port was not recognized. For
Combined Mode (and SCC is still 1), 2 is a value value for MAP.map_value,
and needs to be recognized.

This reverts commit 4596c75c23dde2623cbeec69357d5eb13d28387e as
requested by Olaf Hering. It causes compile errors, and says Olaf:
"This change is also wrong, the autoloading works perfect with 2.6.18,
no need to add random PCI ids.
See commit a0245f7ad5214cb00131d7cd176446e067c913dc, platform devices
have now a modalias entry in sysfs. The network card is not a PCI
device."

This patch is suitable for just about any 2.6 kernel. It should go in
2.6.19 and 2.6.18.2 and possible even the .17 and .16 stable series.
This is a long standing bug that seems to have only recently become
apparent, presumably due to increasing use of NFS over TCP - many
distros seem to be making it the default.
The SK_CONN bit gets set when a listening socket may be ready
for an accept, just as SK_DATA is set when data may be available.
It is entirely possible for svc_tcp_accept to be called with neither
of these set. It doesn't happen often but there is a small race in
svc_sock_enqueue as SK_CONN and SK_DATA are tested outside the
spin_lock. They could be cleared immediately after the test and
before the lock is gained.
This normally shouldn't be a problem. The sockets are non-blocking so
trying to read() or accept() when ther is nothing to do is not a problem.
However: svc_tcp_recvfrom makes the decision "Should I accept() or
should I read()" based on whether SK_CONN is set or not. This usually
works but is not safe. The decision should be based on whether it is
a TCP_LISTEN socket or a TCP_CONNECTED socket.

A disk generated some I/O error, after it, I hitted
J_ASSERT(transaction->t_updates > 0) in journal_stop().
It seems to happened on ext3_truncate() path from stack trace. Then,
maybe the following case may trigger J_ASSERT(transaction->t_updates > 0).
ext3_truncate()
-> ext3_free_branches()
-> ext3_journal_test_restart()
-> ext3_journal_restart()
-> journal_restart()
transaction->t_updates--;
/* another process aborted journal */
-> start_this_handle()
returns -EROFS without transaction->t_updates++;
-> ext3_journal_stop()
-> journal_stop()
J_ASSERT(transaction->t_updates > 0)
If journal was aborted in middle of journal_restart(), ext3_truncate()
may trigger J_ASSERT().

Qooting Adrian:
- net/sunrpc/svc.c uses highest_possible_node_id()
- include/linux/nodemask.h says highest_possible_node_id() is
out-of-line #if MAX_NUMNODES > 1
- the out-of-line highest_possible_node_id() is in lib/cpumask.c
- lib/Makefile: lib-$(CONFIG_SMP) += cpumask.o
CONFIG_ARCH_DISCONTIGMEM_ENABLE=y, CONFIG_SMP=n, CONFIG_SUNRPC=y
-> highest_possible_node_id() is used in net/sunrpc/svc.c
CONFIG_NODES_SHIFT defined and > 0
-> include/linux/numa.h: MAX_NUMNODES > 1
-> compile error
The bug is not present on architectures where ARCH_DISCONTIGMEM_ENABLE
depends on NUMA (but m32r isn't the only affected architecture).
So move the function into page_alloc.c

Interrupts must be disabled during alternative instruction patching. On
systems with high timer IRQ rates, or when running in an emulator, timing
differences can result in random kernel panics because of running partially
patched instructions. This doesn't yet fix NMIs, which requires extricating
the patch code from the late bug checking and is logically separate (and also
less likely to cause problems).

We are using NFS_REPLAY_ME as a special error value that is never leaked to

endian values in the same objects. Network-endian equivalent would work just
as fine; switch to it.
