Stephane Eranian suggestted using 0xff as pseudo code for fixed
uncore event and using the umask value to determine which of the
fixed events we want to map to. So far there is at most one fixed
counter in a uncore PMU. So just change the definition of
UNCORE_FIXED_EVENT to 0xff.

There is no need for keeping separate pmu structs. We can enable
amd_{get,put}_event_constraints() functions also for family 15h event.
The advantage is that there is only a single pmu struct for all AMD
cpus. This patch introduces functions to setup the pmu to enabe core
performance counters or counter constraints.
Also, cpuid checks are used instead of family checks where
possible. Thus, it enables the code independently of cpu families if
the feature flag is set.

"%lu" -> "%llu" is intended (similar for %lx etc.) when a trace was
taken on a machine with 64 bit long integers. However, the current

Besides that, the transformation is only required on systems that don't

be printed as a 6 byte MAC address. But the code does a break over the
main code which updates the current processing arg to point to the
next arg. If there are other print arguments after a %pM, they will be

2) Netfilter ipset mis-compares device names, fix from Florian
Westphal.

4) NFS fixes. Several buffer overflows in NCI layer from Dan

5) Fix WEP handling ath9k, we started using a bit the chip provides to
indicate undecrypted packets but that bit turns out to be unreliable
in certain configurations. Fix from Felix Fietkau.
6) Fix Kconfig dependency bug in wlcore, from Randy Dunlap.

8) Fix crashes in qmi_wwan usbnet driver when disconnecting, from Bjørn
Mork.
9) Gianfar driver programs coalescing settings properly in single queue
mode, but does not do so in multi-queue mode. Fix from Claudiu
Manoil.
10) Missing module.h include in davinci_cpdma.c, from Daniel Mack.
11) Need dummy handler for IPSET_CMD_NONE otherwise we crash in ipset if
we get this via nfnetlink, fix from Tomasz Bursztyka.
12) Missing RCU unlock in nfnetlink error path, also from Tomasz.
13) Fix divide by zero in igbvf when the user tries to set an RX
coalescing value of 0 usecs, from Mitch A Williams.
14) We can process SCTP sacks for the wrong transport, oops. Fix from
Neil Horman.
15) Remove hw IP payload checksumming from e1000e driver. This has zery
value in our stack, and turning it on creates a very unintuitive
restriction for users when using jumbo MTUs.
Specifically, when IP payload checksums are on you cannot use both
receive hashing offload and jumbo MTU. Fix from Bruce Allan.

build error introduced by commit b357f04a67

In commit 070ad7e793 ("floppy: convert to delayed work and
single-thread wq") the 'fd_timeout' timer was converted to a delayed
work. However, the "del_timer(&fd_timeout)" was lost in the process,
and any previous pending timeouts would stay active when we then
re-queued the timeout.
This resulted in the floppy probe sequence having a (stale) 20s timeout
rather than the intended 3s timeout, and thus made booting with the
floppy driver (but no actual floppy controller) take much longer than it
should.
Of course, there's little reason for most people to compile the floppy
driver into the kernel at all, which is why most people never noticed.
Canceling the delayed work where we used to do the del_timer() fixes the
issue, and makes the floppy probing use the proper new timeout instead.
The three second timeout is still very wasteful, but better than the 20s
one.

Pull block bits from Jens Axboe:
"As vacation is coming up, thought I'd better get rid of my pending
changes in my for-linus branch for this iteration. It contains:
- Two patches for mtip32xx. Killing a non-compliant sysfs interface
and moving it to debugfs, where it belongs.
- A few patches from Asias. Two legit bug fixes, and one killing an
interface that is no longer in use.
- A patch from Jan, making the annoying partition ioctl warning a bit
less annoying, by restricting it to !CAP_SYS_RAWIO only.
- Three bug fixes for drbd from Lars Ellenberg.
- A fix for an old regression for umem, it hasn't really worked since
the plugging scheme was changed in 3.0.
- A few fixes from Tejun.
- A splice fix from Eric Dumazet, fixing an issue with pipe
resizing."

The below commit introduced a bug in __clk_set_parent()
which could cause it to *skip* the parent validation
which makes sure the parent passed to the api is a valid
one.
commit 7975059db5
Author: Rajendra Nayak <rnayak@ti.com>
Date: Wed Jun 6 14:41:31 2012 +0530
clk: Allow late cache allocation for clk->parents
This was identified by the following compiler warning..
drivers/clk/clk.c: In function '__clk_set_parent':
drivers/clk/clk.c:1083:5: warning: 'i' may be used uninitialized in this function [-Wuninitialized]
.. as reported by Marc Kleine-Budde.
There were various options discussed on how to fix this, one
being initing 'i' to clk->num_parents, but the below approach
was found to be more appropriate as it also makes the 'parent
validation' code simpler to read.
