Thermal sensor's clk is from pll3_usb_otg, per hardware design requirement, need to make sure pll3_usb_otg is disabled before STOP mode is entered, otherwise, all PFDs under it may enter incorrect state, this patch disables pll3_usb_otg before suspend and enables it after resume.

Pull audit fix from Paul Moore: "One audit patch to resolve a panic/oops when recording filenames in the audit log, see the mail archive link below. The fix isn't as nice as I would like, as it involves an allocate/copy of the filename, but it solves the problem and the overhead should only affect users who have configured audit rules involving file names. We'll revisit this issue with future kernels in an attempt to make this suck less, but in the meantime I think this fix should go into the next release of v3.19-rcX.

2014-12-31Revert "cfg80211: make WEXT compatibility unselectable"Jiri Kosina
This reverts commit 24a0aa212ee2dbe44360288684478d76a8e20a0a. 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.

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.

2014-12-30audit: create private file name copies when auditing inodesPaul Moore
Unfortunately, while commit 4a928436 ("audit: correctly record file names with different path name types") fixed a problem where we were not recording filenames, it created a new problem by attempting to use these file names after they had been freed. This patch resolves the issue by creating a copy of the filename which the audit subsystem frees after it is done with the string. At some point it would be nice to resolve this issue with refcounts, or something similar, instead of having to allocate/copy strings, but that is almost surely beyond the scope of a -rcX patch so we'll defer that for later. On the plus side, only audit users should be impacted by the string copying. Reported-by: Toralf Foerster <toralf.foerster@gmx.de> Signed-off-by: Paul Moore <pmoore@redhat.com>

After the commit ef691ff48bc8 (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.

2014-12-29mm: get rid of radix tree gfp mask for pagecache_get_pageMichal Hocko
Commit 2457aec63745 ("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.

2014-12-29video/logo: prevent use of logos after they have been freedTomi Valkeinen
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. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: stable@vger.kernel.org

2014-12-28kvm: warn on more invariant breakagePaolo Bonzini
Modifying a non-existent slot is not allowed. Also check that the first loop doesn't move a deleted slot beyond the used part of the mslots array. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-12-28kvm: fix sorting of memslots with base_gfn == 0Paolo Bonzini
Before commit 0e60b0799fed (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 0e60b0799fed 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.

2014-12-27netlink/genetlink: pass network namespace to bind/unbindJohannes Berg
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.
