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
much sense: the 'noflags' parameter contains the set of flags that
must not match with the route flags, so the test must be done
against 'noflags', and not against 'flags'.

Under unusual circumstances, TCP collapse can split a big GRO TCP packet
while its being used in a splice(socket->pipe) operation.
skb_splice_bits() releases the socket lock before calling
splice_to_pipe().

__hyp_stub_install duplicates quite a bit of safe_svcmode_maskall
by forcing the CPU back to SVC. This is unnecessary, as
safe_svcmode_maskall is called just after.
Furthermore, the way we build SPSR_hyp is buggy as we fail to mask
the interrupts, leading to interesting behaviours on TC2 + UEFI.
The fix is to simply remove this code and rely on safe_svcmode_maskall
to do the right thing.

commit b080935c8638e08134629d0a9ebdf35669bec14d
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 8fa2206821953a50a3a02ea33fcfb3ced2fd9997
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.

This partially reverts
commit 6c085a728cf000ac1865d66f8c9b52935558b328

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.

This patch is brought to you by the letter 'H'.
Commit 20b279 breaks compatiblity with older perf binaries when run with
precise modifier (:p or :pp) by requiring the exclude_guest attribute to be
set. Older binaries default exclude_guest to 0 (ie., wanting guest-based
samples) unless host only profiling is requested (:H modifier). The workaround
for older binaries is to add H to the modifier list (e.g., -e cycles:ppH -
toggles exclude_guest to 1). This was deemed unacceptable by Linus:
https://lkml.org/lkml/2012/12/12/570
Between family in town and the fresh snow in Breckenridge there is no time left
to be working on the proper fix for this over the holidays. In the New Year I
have more pressing problems to resolve -- like some memory leaks in perf which
are proving to be elusive -- although the aforementioned snow is probably why
they are proving to be elusive. Either way I do not have any spare time to work
on this and from the time I have managed to spend on it the solution is more
difficult than just moving to a new exclude_guest flag (does not work) or
flipping the logic to include_guest (which is not as trivial as one would
think).
So, two options: silently force exclude_guest on as suggested by Gleb which
means no impact to older perf binaries or revert the original patch which
caused the breakage.
This patch does the latter -- reverts the original patch that introduced the
regression. The problem can be revisited in the future as time allows.

This is mostly a port of dbf62d50067e ("ARM: mm: introduce L_PTE_VALID
for page table entries") and 26ffd0d43b18 ("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.

Timezone data is not protected, so the sequence counter is not required

Fix:
vexpress.c: In function ‘vexpress_hwmon_name_show’:
vexpress.c:34:2: error: implicit declaration of function
‘of_get_property’ [-Werror=implicit-function-declaration]
vexpress.c:34:27: warning: initialization makes pointer from integer
without a cast [enabled by default]
vexpress.c: In function ‘vexpress_hwmon_label_show’:
vexpress.c:43:22: warning: initialization makes pointer from integer
without a cast [enabled by default]
Seen if CONFIG_OF_DEVICE is not defined. of_get_property is declared in
of.h which is only included by of_device.h if CONFIG_OF_DEVICE is defined.
of.h needs to be included directly.

If remote device sends l2cap info request before read_remote_ext_feature
completes then mgmt_connected will be sent in hci_acldata_packet() and
remote name request wont be sent and eventually authentication wont happen

This patch moves sending mgmt_connected from hci_acldata_packet() to
l2cap_connect_req() since this code is to handle the scenario remote
device sends l2cap connect req too fast

Card detect for sdhci on Cubox is connected to the wrong pin
(sdio1_cd instead of sdio0_cd). With support for cd-gpios and
pinctrl add the corresponding properties to DT for Cubox.
