9bb29b6b92 ARM: SoC fixes for 3.19-rc3
A very small set of fixes for 3.19, as everyone was out. The clocksource
 patch was something I missed for the merge window after the change that
 broke arm64 was merged through arm-soc. The other two patches are
 a fix for an undetected merge problem in mvebu and a defconfig change
 to make some exynos boards work with the normal multi_v7_defconfig.

831a39c241 Revert "cfg80211: make WEXT compatibility unselectable"
This reverts commit 24a0aa212e.

It's causing severe userspace breakage.  Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore.  There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.

Please see [1] for example of the userspace breakage this is causing.

In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.

To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

007487f1fd Add USB_EHCI_EXYNOS to multi_v7_defconfig
Currently we enable Exynos devices in the multi v7 defconfig, however, when
testing on my ODROID-U3, I noticed that USB was not working.  Enabling this
option causes USB to work, which enables networking support as well since the
ODROID-U3 has networking on the USB bus.

[arnd] Support for odroid-u3 was added in 3.10, so it would be nice to
backport this fix at least that far.

a32442d4f8 OMAPDSS: SDI: fix output port_num
After the commit ef691ff48b (OMAPDSS: DT: Get source endpoint by
matching reg-id) we look for the SDI output using the port number.
However, the SDI driver doesn't set the port number, which causes the
SDI display to not initialize.

Fix this by setting the SDI port number to 1. We use a hardcoded value,
as SDI was used only on OMAP3 and it's always port number 1 there.

 "First of all, the most important change is the thermal cpu cooling
  fixes.  The major fix here is to have proper sequencing between
  cpufreq layer and thermal cpu cooling registration.  A take away of
  this fix is an improvement in the thermal drivers code.  Thermal
  drivers that require cpu cooling do not need to check for cpufreq
  layer.  The requirement now is to propagate the error code, if any,
  while registering cpu cooling device.  Thanks to Viresh for
  implementing the required CPUfreq changes.

  Second, a new driver is introduced for int340x processor thermal
  device.  Given that int340x thermal is disabled by default, and this
  processor thermal device is only available on limited platforms, plus
  the driver does nothing but exposes some thermal limitation
  information for user space to use, thus I think it is safe to include
  it in this pull request after missing 3.19-rc2.

45f87de57f mm: get rid of radix tree gfp mask for pagecache_get_page
Commit 2457aec637 ("mm: non-atomically mark page accessed during page
cache allocation where possible") has added a separate parameter for
specifying gfp mask for radix tree allocations.

Not only this is less than optimal from the API point of view because it
is error prone, it is also buggy currently because
grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if
fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by
AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then
the radix tree allocation wouldn't obey the restriction and might
recurse into filesystem and cause deadlocks.  This is the case for most
filesystems unfortunately because only ext4 and gfs2 are using
AOP_FLAG_NOFS.

Let's simply remove radix_gfp_mask parameter because the allocation
context is same for both page cache and for the radix tree.  Just make
sure that the radix tree gets only the sane subset of the mask (e.g.  do
not pass __GFP_WRITE).

Long term it is more preferable to convert remaining users of
AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this
interface even further.

92b004d1aa video/logo: prevent use of logos after they have been freed
If the probe of an fb driver has been deferred due to missing
dependencies, and the probe is later ran when a module is loaded, the
fbdev framework will try to find a logo to use.

However, the logos are __initdata, and have already been freed. This
causes sometimes page faults, if the logo memory is not mapped,
sometimes other random crashes as the logo data is invalid, and
sometimes nothing, if the fbdev decides to reject the logo (e.g. the
random value depicting the logo's height is too big).

This patch adds a late_initcall function to mark the logos as freed. In
reality the logos are freed later, and fbdev probe may be ran between
this late_initcall and the freeing of the logos. In that case we will
miss drawing the logo, even if it would be possible.

efbeec7098 kvm: fix sorting of memslots with base_gfn == 0
Before commit 0e60b0799f (kvm: change memslot sorting rule from size
to GFN, 2014-12-01), the memslots' sorting key was npages, meaning
that a valid memslot couldn't have its sorting key equal to zero.
On the other hand, a valid memslot can have base_gfn == 0, and invalid
memslots are identified by base_gfn == npages == 0.

Because of this, commit 0e60b0799f broke the invariant that invalid
memslots are at the end of the mslots array.  When a memslot with
base_gfn == 0 was created, any invalid memslot before it were left
in place.

This can be fixed by changing the insertion to use a ">=" comparison
instead of "<=", but some care is needed to avoid breaking the case
of deleting a memslot; see the comment in update_memslots.

Thanks to Tiejun Chen for posting an initial patch for this bug.

023e2cfa36 netlink/genetlink: pass network namespace to bind/unbind
Netlink families can exist in multiple namespaces, and for the most
part multicast subscriptions are per network namespace. Thus it only
makes sense to have bind/unbind notifications per network namespace.

To achieve this, pass the network namespace of a given client socket
to the bind/unbind functions.

Also do this in generic netlink, and there also make sure that any
bind for multicast groups that only exist in init_net is rejected.
This isn't really a problem if it is accepted since a client in a
different namespace will never receive any notifications from such
a group, but it can confuse the family if not rejected (it's also
possible to silently (without telling the family) accept it, but it
would also have to be ignored on unbind so families that take any
kind of action on bind/unbind won't do unnecessary work for invalid
clients like that.

netlink/genetlink cleanups & multicast improvements

I'm looking at using the multicast group functionality in a way that would
benefit from knowing when there are subscribers to avoid collecting the
required data when there aren't any. During this I noticed that the unbind
for multicast groups doesn't actually work - it's never called when sockets
are closed. Luckily, nobody actually uses the functionality.

While looking at the code trying to find why it's not called and where the
multicast listeners are actually removed, I found the potential cleanup in
patch 3. Patch 2 also has a cleanup for a generic netlink API in this area.

Currently, netlink_unbind() is only called when the socket
explicitly unbinds, which limits its usefulness (luckily
there are no users of it yet anyway.)

Call netlink_unbind() also when a socket is released, so it
becomes possible to track listeners with this callback and
without also implementing a netlink notifier (and checking
netlink_has_listeners() in there.)

b10dcb3b94 netlink: update listeners directly when removing socket
The code is now confusing to read - first in one function down
(netlink_remove) any group subscriptions are implicitly removed
by calling __sk_del_bind_node(), but the subscriber database is
only updated far later by calling netlink_update_listeners().

Move the latter call to just after removal from the list so it
is easier to follow the code.

This also enables moving the locking inside the kernel-socket
conditional, which improves the normal socket destruction path.

f8403a2e47 genetlink: pass only network namespace to genl_has_listeners()
There's no point to force the caller to know about the internal
genl_sock to use inside struct net, just have them pass the network
namespace. This doesn't really change code generation since it's
an inline, but makes the caller less magic - there's never any
reason to pass another socket.

02c81ab95d netlink: rename netlink_unbind() to netlink_undo_bind()
The new name is more expressive - this isn't a generic unbind
function but rather only a little undo helper for use only in
netlink_bind().

5242d42297 [regression] braino in "lustre: use is_root_inode()"
In one of the places (ll_md_blocking_ast()) we had open-coded
!is_root_inode(inode) and replaced it with is_root_inode(inode).
See the last chunk of f76c23:
-                   inode != inode->i_sb->s_root->d_inode)
+                   is_root_inode(inode))
should've been
+                   !is_root_inode(inode))
obviously...

eb46e2215f Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth
Johan Hedberg says:

====================
Here's one more bluetooth pull request for 3.19. We've got two fixes:

 - Fix for accepting connections with old user space versions of BlueZ
 - Fix for Bluetooth controllers that don't have a public address

Both of these are regressions that were introduced in 3.17, so the
appropriate Cc: stable annotations are provided.

Please let me know if there are any issues pulling. Thanks.

5f35227ea3 net: Generalize ndo_gso_check to ndo_features_check
GSO isn't the only offload feature with restrictions that
potentially can't be expressed with the current features mechanism.
Checksum is another although it's a general issue that could in
theory apply to anything. Even if it may be possible to
implement these restrictions in other ways, it can result in
duplicate code or inefficient per-packet behavior.

This generalizes ndo_gso_check so that drivers can remove any
features that don't make sense for a given packet, similar to
netif_skb_features(). It also converts existing driver
restrictions to the new format, completing the work that was
done to support tunnel protocols since the issues apply to
checksums as well.

By actually removing features from the set that are used to do
offloading, it solves another problem with the existing
interface. In these cases, GSO would run with the original set
of features and not do anything because it appears that
segmentation is not required.
