Pull block fixes from Jens Axboe:
"Final block fixes for 3.16
Four small fixes that should go into 3.16, have been queued up for a
bit and delayed due to vacation and other euro duties. But here they
are. The pull request contains:
- Fix for a reported crash with shared tagging on SCSI from Christoph
- A regression fix for drbd. From Lars Ellenberg.
- Hooking up the compat ioctl for BLKZEROOUT, which requires no
translation. From Mikulas.
- A fix for a regression where we woud crash on queue exit if the
root_blkg is gone/not there. From Tejun"
* 'for-linus' of git://git.kernel.dk/linux-block:
block: provide compat ioctl for BLKZEROOUT
blkcg: don't call into policy draining if root_blkg is already gone
drbd: fix regression 'out of mem, failed to invoke fence-peer helper'
block: don't assume last put of shared tags is for the host

"Late libata fixes.
The most important one is from Kevin Hao which makes sure that libata

libata always had this problem but the recent tag allocation change
and addition of support for sata_fsl which only supports queue depth
of 16 exposed the issue.

Jonathan writes:
Fifth set of fixes for IIO in the 3.16 cycle.
One nasty one that has been around a long time and a couple of non compliant
ABI fixes.
* The demux code used to split out desired channels for devices that only
support reading sets of channels at one time had a bug where it was
building it's conversion tables against the wrong bitmap resulting in
it never actually demuxing anything. This is an old bug, but will be
effecting an increasing number of drivers as it is often used to avoid
some fiddly code in the individual drivers.
* bma180 and mma8452 weren't obeying the ABI wrt to units for acceleration.
Were in G rather than m/s^2. A little input check was missing from bma180
that might lead to acceptance of incorrect values. This last one is minor
but might lead to incorrect userspace code working and problems in the
future.

BorisO reports that misc_register() fails often on xen. The current code
unregisters the CPU hotplug notifier in that case. If then a CPU is
offlined and onlined back again, we end up with a second timer running
on that CPU, leading to soft lockups and system hangs.
So let's leave the hotcpu notifier always registered - even if
mce_device_create failed for some cores and never unreg it so that we
can deal with the timer handling accordingly.

Haswell and newer Intel CPUs have support for RTM, and in that case DR6.RTM is
not fixed to 1 and DR7.RTM is not fixed to zero. That is not the case in the
current KVM implementation. This bug is apparent only if the MOV-DR instruction
is emulated or the host also debugs the guest.
This patch is a partial fix which enables DR6.RTM and DR7.RTM to be cleared and
set respectively. It also sets DR6.RTM upon every debug exception. Obviously,
it is not a complete fix, as debugging of RTM is still unsupported.

The "uptime" trace clock added in:
commit 8aacf017b065a805d27467843490c976835eb4a5
tracing: Add "uptime" trace clock that uses jiffies
has wraparound problems when the system has been up more
than 1 hour 11 minutes and 34 seconds. It converts jiffies
to nanoseconds using:
(u64)jiffies_to_usecs(jiffy) * 1000ULL
but since jiffies_to_usecs() only returns a 32-bit value, it
truncates at 2^32 microseconds. An additional problem on 32-bit
systems is that the argument is "unsigned long", so fixing the
return value only helps until 2^32 jiffies (49.7 days on a HZ=1000
system).
Avoid these problems by using jiffies_64 as our basis, and
not converting to nanoseconds (we do convert to clock_t because
user facing API must not be dependent on internal kernel
HZ values).

git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into kvm-next
This series enables the "KVM_(S|G)ET_MP_STATE" ioctls on s390 to make
the cpu state settable by user space.
This is necessary to avoid races in s390 SIGP/reset handling which
happen because some SIGPs are handled in QEMU, while others are
handled in the kernel. Together with the busy conditions as return
value of SIGP races happen especially in areas like starting and
stopping of CPUs. (For example, there is a program 'cpuplugd', that
runs on several s390 distros which does automatic onlining and
offlining on cpus.)
As soon as the MPSTATE interface is used, user space takes complete
control of the cpu states. Otherwise the kernel will use the old way.
Therefore, the new kernel continues to work fine with old QEMUs.

This patch cleans up the code in handle_wait by reusing the common code
function kvm_vcpu_block.
signal_pending(), kvm_cpu_has_pending_timer() and kvm_arch_vcpu_runnable() are
sufficient for checking if we need to wake-up that VCPU. kvm_vcpu_block
uses these functions, so no checks are lost.
The flag "timer_due" can be removed - kvm_cpu_has_pending_timer() tests whether
the timer is pending, thus the vcpu is correctly woken up.

When a VLAN interface (on top of batX) is removed and
re-added within a short timeframe TT does not have enough
time to properly cleanup. This creates an internal TT state
mismatch as the newly created softif_vlan will be
initialized from scratch with a TT client count of zero
(even if TT entries for this VLAN still exist). The
resulting TT messages are bogus due to the counter / tt
client listing mismatch, thus creating inconsistencies on
every node in the network
To fix this issue destroy_vlan() has to not free the VLAN
object immediately but it has to be kept alive until all the
TT entries for this VLAN have been removed. destroy_vlan()
still removes the sysfs folder so that the user has the
feeling that everything went fine.
If the same VLAN is re-added before the old object is free'd,
then the latter is resurrected and re-used.
Implement such behaviour by increasing the reference counter
of a softif_vlan object every time a new local TT entry for
such VLAN is created and remove the object from the list
only when all the TT entries have been destroyed.

When the grant operations failed, the skb is freed up eventually, and it tries
to release the frags, if there is any. For the main skb nr_frags is set to 0 to

to call put_page on the page pointer which contains garbage at that time.

When kernel generates a handle for a u32 filter, it tries to start
from the max in the bucket. So when we have a filter with the max (fff)
handle, it will cause kernel always generates the same handle for new
filters. This can be shown by the following command:
tc qdisc add dev eth0 ingress
tc filter add dev eth0 parent ffff: protocol ip pref 770 handle 800::fff u32 match ip protocol 1 0xff
tc filter add dev eth0 parent ffff: protocol ip pref 770 u32 match ip protocol 1 0xff
...
we will get some u32 filters with same handle:
# tc filter show dev eth0 parent ffff:
filter protocol ip pref 770 u32
filter protocol ip pref 770 u32 fh 800: ht divisor 1
filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0
match 00010000/00ff0000 at 8
filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0
match 00010000/00ff0000 at 8
filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0
match 00010000/00ff0000 at 8
filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0
match 00010000/00ff0000 at 8
handles should be unique. This patch fixes it by looking up a bitmap,
so that can guarantee the handle is as unique as possible. For compatibility,
we still start from 0x800.
