ec82f94c7c bfin_mac: Restore hardware time-stamping dependency on BF518
Commit 70ac618c07 ("ptp: fixup Kconfig for two PHC drivers.") removed all
dependencies for the blackfin hardware time-stamping Kconfig entry. Hardware
time-stamping is only available on BF518 though. Since the Kconfig entry is
'default y', just updateing your kernel source and running `make defconfig` will
result in the the following build errors:

	drivers/net/ethernet/adi/bfin_mac.c:694: error: implicit declaration of function ‘bfin_read_EMAC_PTP_CTL’
	drivers/net/ethernet/adi/bfin_mac.c:702: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FV3’
	drivers/net/ethernet/adi/bfin_mac.c:712: error: implicit declaration of function ‘bfin_write_EMAC_PTP_CTL’
	drivers/net/ethernet/adi/bfin_mac.c:717: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FOFF’
	...

This patch adds back the dependency on BF518, and since it does not make sense
to expose this config option when the blackfin MAC driver is not enabled also
restore the dependency on BFIN_MAC.

9d43a18c6e tun: avoid owner checks on IFF_ATTACH_QUEUE
At the moment, we check owner when we enable queue in tun.
This seems redundant and will break some valid uses
where fd is passed around: I think TUNSETOWNER is there
to prevent others from attaching to a persistent device not
owned by them. Here the fd is already attached,
enabling/disabling queue is more like read/write.

6e331f4c83 tuntap: refuse to re-attach to different tun_struct
Multiqueue tun devices support detaching a tun_file from its tun_struct
and re-attaching at a later point in time.  This allows users to disable
a specific queue temporarily.

ioctl(TUNSETIFF) allows the user to specify the network interface to
attach by name.  This means the user can attempt to attach to interface
"B" after detaching from interface "A".

The driver is not designed to support this so check we are re-attaching
to the right tun_struct.  Failure to do so may lead to oops.

21caa6622b ipv6: use addrconf_get_prefix_route for prefix route lookup [v2]
Replace ip6_route_lookup() with addrconf_get_prefix_route() when
looking up for a prefix route. This ensures that the connected prefix
is looked up in the main table, and avoids the selection of other
matching routes located in different tables as well as blackhole
or prohibited entries.

In addition, this fixes an Opps introduced by commit 64c6d08e (ipv6:
del unreachable route when an addr is deleted on lo), that would occur
when a blackhole or prohibited entry is selected by ip6_route_lookup().
Such entries have a NULL rt6i_table argument, which is accessed by
__ip6_del_rt() when trying to lock rt6i_table->tb6_lock.

The function addrconf_is_prefix_route() is not used anymore and is
removed.

[v2] Minor indentation cleanup and log updates.

The tests on the flags in addrconf_get_prefix_route() does no make

must not match with the route flags, so the test must be done

83987ace22 s390/kvm: Fix BUG in include/linux/kvm_host.h:745
commit b080935c86
    kvm: Directly account vtime to system on guest switch

also removed the irq_disable/enable around kvm guest switch, which
is correct in itself. Unfortunately, there is a BUG ON that (correctly)
checks for preemptible to cover the call to rcu later on.
(Introduced with commit 8fa2206821
    KVM: make guest mode entry to be rcu quiescent state)

This check might trigger depending on the kernel config.
Lets make sure that no preemption happens during kvm_guest_enter.
We can enable preemption again after the call to
rcu_virt_note_context_switch returns.

Please note that we continue to run s390 guests with interrupts
enabled.

93927ca52a drm/i915: Revert shrinker changes from "Track unbound pages"
This partially reverts

commit 6c085a728c
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Aug 20 11:40:46 2012 +0200

    drm/i915: Track unbound pages

Closer inspection of that patch revealed a bunch of unrelated changes
in the shrinker:
- The shrinker count is now in pages instead of objects.
- For counting the shrinkable objects the old code only looked at the
  inactive list, the new code looks at all bounds objects (including
  pinned ones). That is obviously in addition to the new unbound list.
- The shrinker cound is no longer scaled with
  sysctl_vfs_cache_pressure. Note though that with the default tuning
  value of vfs_cache_pressue = 100 this doesn't affect the shrinker
  behaviour.
- When actually shrinking objects, the old code first dropped
  purgeable objects, then normal (inactive) objects. Only then did it,
  in a last-ditch effort idle the gpu and evict everything. The new
  code omits the intermediate step of evicting normal inactive
  objects.

Safe for the first change, which seems benign, and the shrinker count
scaling, which is a bit a different story, the endresult of all these
changes is that the shrinker is _much_ more likely to fall back to the
last-ditch resort of idling the gpu and evicting everything.  The old
code could only do that if something else evicted lots of objects
meanwhile (since without any other changes the nr_to_scan will be
smaller than the object count).

Reverting the vfs_cache_pressure behaviour itself is a bit bogus: Only
dentry/inode object caches should scale their shrinker counts with
vfs_cache_pressure. Originally I've had that change reverted, too. But
Chris Wilson insisted that it's too bogus and shouldn't again see the
light of day.

Hence revert all these other changes and restore the old shrinker
behaviour, with the minor adjustment that we now first scan the
unbound list, then the inactive list for each object category
(purgeable or normal).

A similar patch has been tested by a few people affected by the gen4/5
hangs which started to appear in 3.7, which some people bisected to
the "drm/i915: Track unbound pages" commit. But just disabling the
unbound logic alone didn't change things at all.

Note that this patch doesn't fix the referenced bugs, it only hides
the underlying bug(s) well enough to restore pre-3.7 behaviour. The
key to achieve that is to massively reduce the likelyhood of going
into a full gpu stall and evicting everything.

v2: Reword commit message a bit, taking Chris Wilson's comment into
account.

v3: On Chris Wilson's insistency, do not reinstate the rather bogus
vfs_cache_pressure change.

a6fadf7e67 arm64: mm: introduce present, faulting entries for PAGE_NONE
This is mostly a port of dbf62d5006 ("ARM: mm: introduce L_PTE_VALID
for page table entries") and 26ffd0d43b ("ARM: mm: introduce present,
faulting entries for PAGE_NONE") from ARM, which makes use of present,
faulting page table entries for page table entries mapped as PROT_NONE.

The main difference with this implementation is that we can make use of
the two pte type bits in order to avoid allocating a software bit for
identifying PROT_NONE pages, instead reserving the 10b suffix for these
types of mappings.

This is required to prevent users from accessing such pages via syscalls
such as read/write over a pipe.

02522463c8 arm64: mm: only wrprotect clean ptes if they are present
Marking non-present ptes as read-only can corrupt file ptes, breaking
things like swap and file mappings.

This patch ensures that we only manipulate user pte bits when the pte
is marked present.

bdba0051eb arm64: vdso: remove broken, redundant sequence counting for timezones
This patch is an arm64 version of ce73ec6db4 ("powerpc/vdso: Remove
redundant locking in update_vsyscall_tz()").

Timezone data is not protected, so the sequence counter is not required
to ensure consistency. Furthermore, having multiple paths updating the
counter leads to a race between update_vsyscall and update_vsyscall_tz,
so remove the timezone sequence counting from both the kernel and the
vdso.

a8dd2176a8 tracing: Fix regression of trace_options file setting
The latest change to allow trace options to be set on the command
line also broke the trace_options file.

The zeroing of the last byte of the option name that is echoed into
the trace_option file was removed with the consolidation of some
of the code. The compare between the option and what was written to
the trace_options file fails because the string holding the data
written doesn't terminate with a null character.

A zero needs to be added to the end of the string copied from
user space.
