The commit d42fe63d58 ("ALSA: emu10k1: Get rid of set_fs() usage")
converted the user-space copy hack with set_fs() to the direct
memcpy(), but one place was forgotten. This resulted in the error
from snd_emu10k1_init_efx(), eventually failed to load the driver.
Fix the missing piece.

The Broadcom controller on the Raspberry Pi3 sends an empty packet with
packet type 0x00 after launching the firmware. This will cause logging
of errors.
Bluetooth: hci0: Frame reassembly failed (-84)
Since this seems to be an intented behaviour of the controller, handle
it gracefully by parsing that empty packet with packet type 0x00 and
then just simply report it as diagnostic packet.
With that change no errors are logging and the packet itself is actually
recorded in the Bluetooth monitor traces.

If we fail a mount on account of cow recovery errors, it's possible that

Way back when we established inode block-map redo log items, it was
discovered that we needed to prevent the VFS from evicting inodes during
log recovery because any given inode might be have bmap redo items to
replay even if the inode has no link count and is ultimately deleted,
and any eviction of an unlinked inode causes the inode to be truncated
and freed too early.
To make this possible, we set MS_ACTIVE so that inodes would not be torn
down immediately upon release. Unfortunately, this also results in the
quota inodes not being released at all if a later part of the mount
process should fail, because we never reclaim the inodes. So, set
MS_ACTIVE right before we do the last part of log recovery and clear it
immediately after we finish the log recovery so that everything
will be torn down properly if we abort the mount.

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
quota: correct space limit check
Christian Brauner reported that if you use the TIOCGPTPEER ioctl() to
get a slave pty file descriptor, the resulting file descriptor doesn't
look right in /proc/<pid>/fd/<fd>. In particular, he wanted to use
readlink() on /proc/self/fd/<fd> to get the pathname of the slave pty
(basically implementing "ptsname{_r}()").
The reason for that was that we had generated the wrong 'struct path'
when we create the pty in ptmx_open().
In particular, the dentry was correct, but the vfsmount pointed to the
mount of the ptmx node. That _can_ be correct - in case you use
"/dev/pts/ptmx" to open the master - but usually is not. The normal
case is to use /dev/ptmx, which then looks up the pts/ directory, and
then the vfsmount of the ptmx node is obviously the /dev directory, not
the /dev/pts/ directory.
We actually did have the right vfsmount available, but in the wrong
place (it gets looked up in 'devpts_acquire()' when we get a reference
to the pts filesystem), and so ptmx_open() used the wrong mnt pointer.
The end result of this confusion was that the pty worked fine, but when
if you did TIOCGPTPEER to get the slave side of the pty, end end result
would also work, but have that dodgy 'struct path'.
And then when doing "d_path()" on to get the pathname, the vfsmount
would not match the root of the pts directory, and d_path() would return
an empty pathname thinking that the entry had escaped a bind mount into
another mount.
This fixes the problem by making devpts_acquire() return the vfsmount
for the pts filesystem, allowing ptmx_open() to trivially just use the
right mount for the pts dentry, and create the proper 'struct path'.

Historically, DMA masks have suffered some ambiguity between whether
they represent the range of physical memory a device can access, or the
address bits a device is capable of driving, particularly since on many
platforms the two are equivalent. Whilst there are some stragglers left
(dma_max_pfn(), I'm looking at you...), the majority of DMA code has
been cleaned up to follow the latter definition, not least since it is
the only one which makes sense once IOMMUs are involved.
In this respect, of_dma_configure() has always done the wrong thing in
how it generates initial masks based on "dma-ranges". Although rounding
down did not affect the TI Keystone platform where dma_addr + size is
already a power of two, in any other case it results in a mask which is
at best unnecessarily constrained and at worst unusable.
BCM2837 illustrates the problem nicely, where we have a DMA base of 3GB
and a size of 1GB - 16MB, giving dma_addr + size = 0xff000000 and a
resultant mask of 0x7fffffff, which is then insufficient to even cover
the necessary offset, effectively making all DMA addresses out-of-range.
This has been hidden until now (mostly because we don't yet prevent
drivers from simply overwriting this initial mask later upon probe), but
due to recent changes elsewhere now shows up as USB being broken on
Raspberry Pi 3.
Make it right by rounding up instead of down, such that the mask
correctly correctly describes all possisble bits the device needs to
emit.

__startup_64() is normally using fixup_pointer() to access globals in a
position-independent fashion. However 'next_early_pgt' was accessed
directly, which wasn't guaranteed to work.
Luckily GCC was generating a R_X86_64_PC32 PC-relative relocation for
'next_early_pgt', but Clang emitted a R_X86_64_32S, which led to
accessing invalid memory and rebooting the kernel.

"Two small fixes to the audit code, both explained well in the
respective patch descriptions, but the quick summary is one
use-after-free fix, and one silly fanotify notification flag fix"
* tag 'audit-pr-20170816' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit:

While working on yet another syzkaller report, I found
that our IP_MAX_MTU enforcements were not properly done.
gcc seems to reload dev->mtu for min(dev->mtu, IP_MAX_MTU), and
final result can be bigger than IP_MAX_MTU :/
This is a problem because device mtu can be changed on other cpus or
threads.
While this patch does not fix the issue I am working on, it is
probably worth addressing it.

As found by syzkaller, malicious users can set whatever tx_queue_len
on a tun device and eventually crash the kernel.
Lets remove the ALIGN(XXX, SMP_CACHE_BYTES) thing since a small
ring buffer is not fast anyway.

vmbus sendpacket cleanups
These patches remove and consolidate vmbus_sendpacket functions.
They should go through the net-next tree since these API's

I made a stupid mistake using TC_CLSFLOWER_STATS instead of
TC_SETUP_CLSFLOWER. Funny thing is that both are defined as "2" so it
actually did not cause any harm. Anyway, fixing it now.

tun_build_skb() is not thread safe since it uses per queue page frag,
this will break things when multiple threads are sending through same
queue. Switch to use per-thread generator (no lock involved).
