Merge hpfs updates from Mikulas Patocka.
Mainly fstrim support, with some minor other cleanups.
These were actually sent during the merge window, but I wanted to wait
for the FSTRIM compat handling cleanup before applying them. Mikulas
sent that earlier today.
* emailed patches from Mikulas Patocka <mikulas@twibright.com>:
hpfs: hpfs_error: Remove static buffer, use vsprintf extension %pV instead
hpfs: kstrdup() out of memory handling
hpfs: Remove unessary cast
hpfs: add fstrim support

Removing unnecessary static buffers is good.
Use the vsprintf %pV extension instead.

Pull Ceph fixes from Sage Weil:
"There is a fix for CephFS and RBD when used within containers/namespaces,
and a fix for the address learning the client is supposed to do when
initially talking to the Ceph cluster.
There are also two patches updating MAINTAINERS. One breaks out the
common Ceph code shared by fs/ceph and drivers/block/rbd.c into a
separate entry with the appropriate maintainers listed. The second
adds a second reference to the github tree where the Ceph client
development takes place (before it is pushed to korg and then to you).
The goal here is to move closer to a situation where Ilya Dryomov or
one of the other maintainers can push things to you if I am
unavailable. Ilya has done most of the work preparing branches for
upstream recently; you should not be surprised to hear from him if I
am trapped in some internet-less wasteland or hit by a bus or
something. In the meantime, we'll work on getting him added to the
kernel web of trust"

The firmware class uevent function accessed the "fw_priv->buf" buffer
without the proper locking and testing for NULL. This is an old bug
(looks like it goes back to 2012 and commit 1244691c73b2: "firmware
loader: introduce firmware_buf"), but for some reason it's triggering
only now in 4.2-rc1.
Shuah Khan is trying to bisect what it is that causes this to trigger
more easily, but in the meantime let's just fix the bug since others are
hitting it too (at least Ingo reports having seen it as well).

Reading page fault handler code I've noticed that under right
circumstances kernel would map anonymous pages into file mappings: if
the VMA doesn't have vm_ops->fault() and the VMA wasn't fully populated
on ->mmap(), kernel would handle page fault to not populated pte with
do_anonymous_page().
Let's change page fault handler to use do_anonymous_page() only on
anonymous VMA (->vm_ops == NULL) and make sure that the VMA is not
shared.
For file mappings without vm_ops->fault() or shred VMA without vm_ops,
page fault on pte_none() entry would lead to SIGBUS.

addr_is_blank() should return true if family is neither AF_INET nor
AF_INET6. This is what its counterpart entity_addr_t::is_blank_ip() is
doing and it is the right thing to do: in process_banner() we check if
our address is blank and if it is "learn" it from our peer. As it is,
we never learn our address and always send out a blank one. This goes
way back to ceph.git commit dd732cbfc1c9 ("use sockaddr_storage; and
some ipv6 support groundwork") from 2009.
While at at, do not open-code ipv6_addr_any() and use INADDR_ANY
constant instead of 0.

Grab a reference on a network namespace of the 'rbd map' (in case of
rbd) or 'mount' (in case of ceph) process and use that to open sockets
instead of always using init_net and bailing if network namespace is
anything but init_net. Be careful to not share struct ceph_client
instances between different namespaces and don't add any code in the
!CONFIG_NET_NS case.

The old style of memory interleaving swizzled upto the end of the
first even bank of memory, and then used the remainder as unswizzled on
the unpaired bank - i.e. swizzling is not constant for all memory. This
causes problems when we try to migrate memory and so the kernel prevents
migration at all when we detect L-shaped inconsistent swizzling.
However, this issue also extends to userspace who try to manually detile
into memory as the swizzling for an individual page is unknown (it
depends on its physical address only known to the kernel), userspace
cannot correctly swizzle objects.
v2: Mark the global swizzling as unknown rather than adjust the value
reported to userspace.

The tilegx and tilepro compilers use .coldtext for their unlikely

will (when compiled with higher optimization levels) land in
the .coldtext section.
Modify modpost to add .coldtext to the set of OTHER_TEXT_SECTIONS
so we don't get warnings about referencing such a section in an
__ex_table block, and then also modify arch/tile/lib/memcpy_user_64.c
so that it uses plain ".coldtext" instead of ".coldtext.memcpy".
The latter naming is a relic of an earlier use of -ffunction-sections,
which we no longer use by default.

Trying to resolve issues with missed vblanks and impossible
values inside delivered kms pageflip completion events showed
that radeon's irq handling sometimes doesn't handle valid irqs,
but silently skips them. This was observed for vblank interrupts.
Although those irqs have corresponding events queued in the gpu's
irq ring at time of interrupt, and therefore the corresponding
handling code gets triggered by these events, the handling code
sometimes silently skipped processing the irq. The reason for those
skips is that the handling code double-checks for each irq event if
the corresponding irq status bits in the irq status registers
are set. Sometimes those bits are not set at time of check
for valid irqs, maybe due to some hardware race on some setups?
The problem only seems to happen on some machine + card combos
sometimes, e.g., never happened during my testing of different PC
cards of the DCE-2/3/4 generation a year ago, but happens consistently
now on two different Apple Mac cards (RV730, DCE-3, Apple iMac and
Evergreen JUNIPER, DCE-4 in a Apple MacPro). It also doesn't happen
at each interrupt but only occassionally every couple of
hundred or thousand vblank interrupts.
This results in XOrg warning messages like
"[ 7084.472] (WW) RADEON(0): radeon_dri2_flip_event_handler:
Pageflip completion event has impossible msc 420120 < target_msc 420121"
as well as skipped frames and problems for applications that
use kms pageflip events or vblank events, e.g., users of DRI2 and
DRI3/Present, Waylands Weston compositor, etc. See also
https://bugs.freedesktop.org/show_bug.cgi?id=85203
After some talking to Alex and Michel, we decided to fix this
by turning the double-check for asserted irq status bits into a
warning. Whenever a irq event is queued in the IH ring, always
execute the corresponding interrupt handler. Still check the irq
status bits, but only to log a DRM_DEBUG message on a mismatch.
This fixed the problems reliably on both previously failing
cards, RV-730 dual-head tested on both crtcs (pipes D1 and D2)
and a triple-output Juniper HD-5770 card tested on all three
available crtcs (D1/D2/D3). The r600 and evergreen irq handling
is therefore tested, but the cik an si handling is only compile
tested due to lack of hw.

The "fix" in commit 0b08c5e5944 ("audit: Fix check of return value of
strnlen_user()") didn't fix anything, it broke things. As reported by
Steven Rostedt:
"Yes, strnlen_user() returns 0 on fault, but if you look at what len is
set to, than you would notice that on fault len would be -1"
because we just subtracted one from the return value. So testing
against 0 doesn't test for a fault condition, it tests against a
perfectly valid empty string.
Also fix up the usual braindamage wrt using WARN_ON() inside a
conditional - make it part of the conditional and remove the explicit
unlikely() (which is already part of the WARN_ON*() logic, exactly so
that you don't have to write unreadable code.

drm/i915: Use atomic helpers for computing changed flags

any changes, which means crtc->active won't be correct yet. Looking at
future work in the modeset conversion targetting 4.3 the only places
where crtc_state->active isn't accurate is when disabling other CRTCs
than the one the modeset is for (when stealing connectors). Which
isn't the case here. And that's also confirmed by an audit, we do
unconditionally update crtc_state->active for the current pipe.
We also don't need to update any other plane check functions since we
only ever add the primary state to the modeset update right now.

Pull ARM updates from Russell King:
"These are late by a week; they should have been merged during the
merge window, but unfortunately, the ARM kernel build/boot farms were
indicating random failures, and it wasn't clear whether the cause was
something in these changes or something during the merge window.
This is a set of merge window fixes with some documentation additions"

In function mei_nfc_host_exit mei_cl_remove_device cannot be called
under the device mutex as device removing flow invokes the device driver
remove handler that calls in turn to mei_cl_disable_device which
naturally acquires the device mutex.
Also remove mei_cl_bus_remove_devices which has the same issue, but is
never executed as currently the only device on the mei client bus is NFC
and a new device cannot be easily added till the bus revamp is
completed.
This fixes regression caused by commit be9b720a0ccb ("mei_phy: move all
nfc logic from mei driver to nfc")
Prior to this change the nfc driver remove handler called to no-op
disable function while actual nfc device was disabled directly from the
mei driver.

If dev_pm_attach_wake_irq() fails, the device's power.wakeirq field
should not be set to point to the struct wake_irq passed to that
function, as that object will be freed going forward.
For this reason, make dev_pm_attach_wake_irq() first call
device_wakeup_attach_irq() and only set the device's power.wakeirq
field if that's successful.
That requires device_wakeup_attach_irq() to be called under the
device's power.lock lock, but since dev_pm_attach_wake_irq() is
the only caller of it, the requisite changes are easy to make.
