This patch (as1199) changes the initial wakeup settings for PCI USB
host controllers. The controllers are marked as capable of waking the
system, but wakeup is not enabled by default.
It turns out that enabling wakeup for USB host controllers has a lot
of bad consequences. As the simplest example, if a USB mouse or
keyboard is unplugged immediately after the computer is put to sleep,
the unplug will cause the system to wake back up again! We are better
off marking them as wakeup-capable and leaving wakeup disabled.

This patch (as1200) finishes some fixes that were left incomplete by
an earlier patch.
Although nobody has addressed this issue in the past, it turns out
that we need to distinguish between two different modes of disabling
and enabling endpoints. In one mode only the data structures in
usbcore are affected, and in the other mode the host controller and
device hardware states are affected as well.
The earlier patch added an extra argument to the routines in the
enable_endpoint pathways to reflect this difference. This patch adds
corresponding arguments to the disable_endpoint pathways. Without
this change, the endpoint toggle state can get out of sync between
the host and the device. The exact mechanism depends on the details
of the host controller (whether or not it stores its own copy of the
toggle values).

nfsd4_lockt does a search for a lockstateowner when building the lock
struct to test. If one is found, it'll set fl_owner to it. Regardless of
whether that happens, it'll also set fl_lmops. Given that this lock is
basically a "lightweight" lock that's just used for checking conflicts,
setting fl_lmops is probably not appropriate for it.
This behavior exposed a bug in DLM's GETLK implementation where it
wasn't clearing out the fields in the file_lock before filling in
conflicting lock info. While we were able to fix this in DLM, it
still seems pointless and dangerous to set the fl_lmops this way
when we may have a NULL lockstateowner.

This, in turn, may result in shortening the disk's life times.
To prevent this from happening we can blacklist the affected systems
using DMI information. However, only the on-board controlles should
be blacklisted and their PCI slot numbers can be used for this
purpose. Unfortunately the existing interface for checking DMI
information of the system is not very convenient for this purpose,
because to use it, we would have to define special callback functions
or create a separate struct dmi_system_id table for each blacklisted
system.
To overcome this difficulty introduce a new function
dmi_first_match() returning a pointer to the first entry in an array
of struct dmi_system_id elements that matches the system DMI
information. Then, we can use this pointer to access the entry's
.driver_data field containing the additional information, such as
the PCI slot number, allowing us to do the desired blacklisting.

Some device drivers need such a function to check if the system is

are going to use it for blacklisting systems in which the disks
should not be spun down during the last phase of hibernation (the
BIOS will do that anyway).

Part of the code that did not make sense to me got removed by Greg.
This is part two:
The first compare is to check whether the interrupts are disabled or not.
Depending on the result we exectute the RESTORE_ALL macro is not only
restoring the stack but also returning to caller.
The test for pending softirq has been removed because it is allready done
in irq_exit().
Since system_call() is allso using the SAVE_ALL macro and returning via
ret_from_exception label I see no reason why we could not do this here
as well. This is also handy because if we return from the timer interrupt
and we need to resched than we check for this :)

tcp_splice_data_recv has two lengths to consider: the len parameter it
gets from tcp_read_sock, which specifies the amount of data in the skb,
and rd_desc->count, which is the amount of data the splice caller still
wants. Currently it passes just the latter to skb_splice_bits, which then
splices min(rd_desc->count, skb->len - offset) bytes.
Most of the time this is fine, except when the skb contains urgent data.
In that case len goes only up to the urgent byte and is less than
skb->len - offset. By ignoring len tcp_splice_data_recv may a) splice
data tcp_read_sock told it not to, b) return to tcp_read_sock a value > len.
Now, tcp_read_sock doesn't handle used > len and leaves the socket in a
bad state (both sk_receive_queue and copied_seq are bad at that point)
resulting in duplicated data and corruption.
Fix by passing min(rd_desc->count, len) to skb_splice_bits.

The fix is trivial: in crypto/ccm.c:crypto_ccm_auth(), pctx->ilen contains
whatever was in memory when pctx was allocated if assoclen is 0. The tested
fix is to simply add an else clause setting pctx->ilen to 0 for the
assoclen == 0 case, so that get_data_to_compute() doesn't try doing

commit 9088c56095
(udp: Improve port randomization) introduced a regression for UDP bind() syscall
to null port (getting a random port) in case lot of ports are already in use.
This is because we do about 28000 scans of very long chains (220 sockets per chain),
with many spin_lock_bh()/spin_unlock_bh() calls.
Fix this using a bitmap (64 bytes for current value of UDP_HTABLE_SIZE)
so that we scan chains at most once.
Instead of 250 ms per bind() call, we get after patch a time of 2.9 ms
