There are many drivers that have been setting the generic driver
model level shutdown callback, and pci thus must not override it.
Without this patch we can have really bad data loss on various
raid controllers.

__cfq_get_queue(). __cfq_get_queue() finds an existing queue (struct
cfq_queue) of the current process for the device and returns it. If it's not
found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is
called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that
get_request() fails) if no __GFP_WAIT flag.
On the other hand, in __make_request(), get_request() is called without
__GFP_WAIT flag at the first time. Thus, the get_request() fails when there is
no existing queue, typically when it's called for the first I/O request of the
process to the device.
Though it will be followed by get_request_wait() for general case,
__make_request() will just end the I/O with an error (EWOULDBLOCK) when the
request was for read-ahead.

It looks like logic for enabling hardware tapping in ALPS driver was
inverted and we enable it only if it was already enabled by BIOS or
firmware.
I have a confirmation from one user that the patch below fixes the problem
for him and it might be beneficial if we could get it into 2.6.12.

The ELF core dump code has one use of off_t when writing out segments.
Some of the segments may be passed the 2GB limit of an off_t, even on a
32-bit system, so it's important to use loff_t instead. This fixes a
corrupted core dump in the bigcore test in GDB's testsuite.

This fixed a problem that showed up in the Fedora development tree a few
weeks before the Fedora Core 4 release, initially as slab corruption, later
as hard crashes on boot up, when slab debugging was disabled for the
release. More details on the history at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424
The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a
scsi_id, without explicitly requesting space for it. Since hostdata is
declared as a zero-sized array, we don't get any such space by default, so
it must be explicitly requested. The patch below implements just that.

__elv_add_request(). rq.count[READ] + rq.count[WRITE] can increase
more than one if another thread has allocated a request after the
current request is allocated or in_flight could have changed resulting
in larger-than-one change of nrq, thus breaking the threshold
mechanism.

Without this patch, some usb kobjects, which are parents to the usx2y's
kobjects can be freed before the usx2y's. This led to an oops in
get_kobj_path_length() and a dead keyboard, when the usx2y's kobjects
were freed. The patch ensures the correct sequence. Tested ok on

On 64-bit machines, PCI_BASE_ADDRESS_MEM_MASK and other mask constants
passed to pci_size() are 64-bit (for example ~0x0fUL). However, pci_size
does comparisons between the u32 arguments and the mask, which will fail
even though any result from pci_size is still just 32-bit.
Changing the mask argument to u32 seems the obvious thing to do, since all
arithmetic in the function is 32-bit and having a larger mask makes no
sense.
This triggered on a PPC64 system here where an adapter (VGA, as it
happened) had a memory region base of 0xfe000000 and a sz of the same,
matching the if (max == maxbase ...) test at the bottom of pci_size but
failing the mask comparison. Quite a corner case which I guess explains
why we haven't seen it until now.

This patch alows you to change the source address of icmp error
messages. It applies cleanly to 2.6.11.11 and retains the default
behaviour.
In the old (default) behaviour icmp error messages are sent with the ip
of the exiting interface.
The new behaviour (when the sysctl variable is toggled on), it will send
the message with the ip of the interface that received the packet that
caused the icmp error. This is the behaviour network administrators will
expect from a router. It makes debugging complicated network layouts
much easier. Also, all 'vendor routers' I know of have the later
behaviour.

Userland layer-2 tunneling devices allocated through the TUNTAP driver
(drivers/net/tun.c) have a type of ARPHRD_NONE, and have no link-layer
address. The kernel complains at regular interval when IPv6 Privacy
extension are enabled because it can't find an hardware address :
Dec 29 11:02:04 auguste kernel: __ipv6_regen_rndid(idev=cb3e0c00):
cannot get EUI64 identifier; use random bytes.
IPv6 Privacy extensions should probably be disabled on that sort of
device. They won't work anyway. If userland wants a more usual
Ethernet-ish interface with usual IPv6 autoconfiguration, it will use a
TAP device with an emulated link-layer and a random hardware address
rather than a TUN device.
As far as I could fine, TUN virtual device from TUNTAP is the very only
sort of device using ARPHRD_NONE as kernel device type.

We saw following trace several times:
|BUG: using smp_processor_id() in preemptible [00000001] code: httpd/30137
|caller is icmpv6_send+0x23/0x540
| [<c01ad63b>] smp_processor_id+0x9b/0xb8
| [<c02993e7>] icmpv6_send+0x23/0x540
This is because of icmpv6_socket, which is the only one user of
smp_processor_id() in icmpv6_send(), AFAIK.
Since it should be used in non-preemptive context,
let's defer the dereference after disabling preemption
(by icmpv6_xmit_lock()).
