- Increases the minor number limitation for vbi devices from 223 to 255.
This is in agreement with the minor number allocation specified in
Documentation/devices.txt.
- Without this patch it is not possible to use more than 5 Hauppauge
WinTV-PVR 350 cards since each of these allocate 3 vbi devices.

Correctly specify treeboot based image entrypoint. Currently makefile uses
$(ENTRYPOINT) which isn't defined anywhere. Each board port sets
entrypoint-$(CONFIG_BOARD_NAME) instead.
Without this patch I cannot boot Ocotea (PPC440GX eval board) anymore. I
was getting random "OS panic" errors from OpenBIOS for a while, but with
current kernel I get them all the time (probably because image became
bigger).

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".
This fixes netfilter bugs #383 and #395.

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.

Nick and I had already been looking at drivers/scsi/{sg.c,st.c},
brought there by __put_page in sg.c's peculiar sg_rb_correct4mmap,
which we'd like to remove. But that's irrelevant to your pain, except...
One extract from the patches I'd like to send Doug and Kai for 2.6.15
or 2.6.16 is this below: since the incomplete get_user_pages path omits
to reset res, but has already released all the pages, it will result in
premature freeing of user pages, and behaviour just like you've seen.
Though I'd have thought incomplete get_user_pages was an exceptional
case, and a bit surprised you'd encounter it. Perhaps there's some
other premature freeing in the driver, and this instance has nothing
whatever to do with it.
If the problem were easily reproducible, it'd be great if you could
try this patch; but I think you've said it's not :-(

Some SCSI devices apparently get very confused if we try to use the
echo buffer on a non-DT negotiated bus (this mirrors the problems of
using PPR on non-LVD for some devices). The fix is to be far more
conservative about when we use an echo buffer. With this patch, we'll
now see what parameters are negotiated by the read only test, and only
look for an echo buffer if DT is negotiated.

ARMv6K CPUs have SEV (send event) and WFE (wait for event) instructions
which allow the CPU clock to be suspended until another CPU issues a
SEV, rather than spinning on the lock wasting power. Make use of these
instructions.
Note that WFE does not wait if an event has been sent since the last WFE
cleared the event status, so although it may look racy, the instruction
implementation ensures that these are dealt with.

This patch fixes graceful stop timeout handling in PPC4xx EMAC driver.
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.
