Both proc files are writeable and used for configuring cells. But there is missing correct mode flag for writeable files. Without this patch both proc files are read only.

With commit d8d14bd0 ("fs/compat: fix lookup_dcookie() parameter handling") I changed the type of the len parameter of the lookup_dcookie() syscall. However I missed that there was still a stale declaration in arch/tile/.. which now causes a compile error on tile: In file included from fs/dcookies.c:28:0: include/linux/compat.h:425:17: error: conflicting types for 'compat_sys_lookup_dcookie' fs/dcookies.c:207:1: error: conflicting types for 'compat_sys_lookup_dcookie' Simply remove the declaration in the tile architecture, which is only a leftover from before the different compat lookup_dcookie() versions have been merged. The correct declaration is now in include/linux/compat.h The build error was reported by Fenguang's build bot.

Revert commit ef83b078 "PCI: Remove from bus_list and release resources in pci_release_dev()" that made some nasty race conditions become possible. For example, if a Thunderbolt link is unplugged and then replugged immediately, the pci_release_dev() resulting from the hot-remove code path may be racing with the hot-add code path which after that commit causes various kinds of breakage to happen (up to and including a hard crash of the whole system). Moreover, the problem that commit ef83b078 attempted to address cannot happen any more after commit 8a4c5c32 "PCI: Check parent kobject in pci_destroy_dev()", because pci_destroy_dev() will now return immediately if it has already been executed for the given device. Note, however, that the invocation of msi_remove_pci_irq_vectors() removed by commit ef83b078 from pci_free_resources() along with the other changes made by it is not added back because of subsequent code changes depending on that modification.

Move sync_filesystem() after sb_prepare_remount_readonly(). If writers sneak in anywhere from sync_filesystem() to sb_prepare_remount_readonly() it can cause inodes to be dirtied and writeback to occur well after sys_mount() has completely successfully. This was spotted by corrupted ubifs filesystems on reboot, but appears that it can cause issues with any filesystem using writeback.

Pull ACPI and power management fixes and cleanups from Rafael Wysocki: - ACPI device hotplug fix preventing ACPI drivers from binding to device objects that acpi_bus_trim() has been called for and the devices represented by them may not be operational. - Recent cpufreq changes related to the "boost" (turbo) feature broke the acpi-cpufreq error code path causing a NULL pointer dereference to occur on some systems. Fix from Konrad Rzeszutek Wilk. - The log level of a CPU initialization error message added recently needs to be reduced, because the particular BIOS issue indicated by it turns out to be widespread and doesn't really matter for the majority of systems having it. From Jiang Liu. - The regulator API needs to be told to stay away from things on systems with ACPI BIOSes or it may conflict with the BIOS' own handling of voltage regulators. Fix from Mark Brown that works around a 3.13 regression in lm90 on PCs occuring if the regulator API is enabled. - Prevent the Exynos4 devfreq driver from being built on multiplatform, because it depends on things that aren't available during such builds. From Sachin Kamat. - Upstream ACPICA doesn't use the bool type as defined in the kernel, so modify the kernel's ACPICA code to follow the upstream in that respect (only one variable definition is affected) to reduce divergences between the two. From Lv Zheng. - Make the ACPI device PM code use ACPI_COMPANION() instead of its own routine doing the same thing (and invokng ACPI_COMPANION() in the process). - Modify some routines in the ACPI processor driver to follow the common convention and return negative integers on errors.

The patch 3ddc5b46 breaks networking on alpha (there is a follow-up fix 5cfe8f1b, but networking is still broken even with the second patch). The patch 3ddc5b46 makes csum_partial_copy_from_user check the pointer with access_ok. However, csum_partial_copy_from_user is called also from csum_partial_copy_nocheck and csum_partial_copy_nocheck is called on kernel pointers and it is supposed not to check pointer validity. This bug results in ssh session hangs if the system is loaded and bulk data are printed to ssh terminal. This patch fixes csum_partial_copy_nocheck to call set_fs(KERNEL_DS), so that access_ok in csum_partial_copy_from_user accepts kernel-space addresses.

Commit 384a48d7 "ALSA: hda: HDMI: Support codecs with fewer cvts than pins" dynamically enabled each pin widget's PIN_OUT only when the pin was actively in use. This was required on certain NVIDIA CODECs for correct operation. Specifically, if multiple pin widgets each had their mux input select the same audio converter widget and each pin widget had PIN_OUT enabled, then only one of the pin widgets would actually receive the audio, and often not the one the user wanted! However, this apparently broke some Intel systems, and commit 6169b673 "ALSA: hda - Always turn on pins for HDMI/DP" reverted the dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA CODECs. This change supports either dynamic or static handling of PIN_OUT, selected by a flag set up during CODEC initialization. This flag is enabled for all recent NVIDIA GPUs.

MF Symlinks are regular files containing content in a specified format. The function couldbe_mf_symlink() checks the mode for a set S_IFREG bit as a test to confirm that it is a regular file. This bit is also set for other filetypes and simply checking for this bit being set may return false positives.

Current xen-selfballoon driver is too aggressive which may cause OOM be triggered more often. Eg. this bug reported by James: https://lkml.org/lkml/2013/11/21/158 There are two mainly reasons: 1) The original goal_page didn't consider some pages used by kernel space, like slab pages and pages used by device drivers. 2) The balloon driver may not give back memory to guest OS fast enough when the workload suddenly aquries a lot of physical memory. In both cases, the guest OS will suffer from memory pressure and OOM may be triggered. The fix is make xen-selfballoon driver not that aggressive by adding extra 10% of total ram pages to goal_page. It's more valuable to keep the guest system reliable and response faster than balloon out these 10% pages to XEN.

Therefore this series does the following: - the original functions were renamed to __gnttab_[un]map_refs, with a new parameter m2p_override - based on m2p_override either they follow the original behaviour, or just set the private flag and call set_phys_to_machine - gnttab_[un]map_refs are now a wrapper to call __gnttab_[un]map_refs with m2p_override false - a new function gnttab_[un]map_refs_userspace provides the old behaviour It also removes a stray space from page.h and change ret to 0 if XENFEAT_auto_translated_physmap, as that is the only possible return value there. v2: - move the storing of the old mfn in page->index to gnttab_map_refs - move the function header update to a separate patch v3: - a new approach to retain old behaviour where it needed - squash the patches into one v4: - move out the common bits from m2p* functions, and pass pfn/mfn as parameter - clear page->private before doing anything with the page, so m2p_find_override won't race with this v5: - change return value handling in __gnttab_[un]map_refs - remove a stray space in page.h - add detail why ret = 0 now at some places v6: - don't pass pfn to m2p* functions, just get it locally Signed-off-by: Zoltan Kiss <zoltan.kiss@citrix.com> Suggested-by: David Vrabel <david.vrabel@citrix.com> Acked-by: David Vrabel <david.vrabel@citrix.com> Acked-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

We have the following means for encoding writable or dirty ptes: PTE_DIRTY PTE_RDONLY !pte_dirty && !pte_write 0 1 !pte_dirty && pte_write 0 1 pte_dirty && !pte_write 1 1 pte_dirty && pte_write 1 0 So we can't distinguish between writable clean ptes and read only ptes. This can cause problems with ptes being incorrectly flagged as read only when they are writable but not dirty. This patch introduces a new software bit PTE_WRITE which allows us to correctly identify writable ptes. PTE_RDONLY is now only clear for valid ptes where a page is both writable and dirty.

Pull btrfs updates from Chris Mason: "This is a pretty big pull, and most of these changes have been floating in btrfs-next for a long time. Filipe's properties work is a cool building block for inheriting attributes like compression down on a per inode basis. Jeff Mahoney kicked in code to export filesystem info into sysfs. Otherwise, lots of performance improvements, cleanups and bug fixes. Looks like there are still a few other small pending incrementals, but I wanted to get the bulk of this in first" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (149 commits) Btrfs: fix spin_unlock in check_ref_cleanup Btrfs: setup inode location during btrfs_init_inode_locked Btrfs: don't use ram_bytes for uncompressed inline items Btrfs: fix btrfs_search_slot_for_read backwards iteration Btrfs: do not export ulist functions Btrfs: rework ulist with list+rb_tree Btrfs: fix memory leaks on walking backrefs failure Btrfs: fix send file hole detection leading to data corruption Btrfs: add a reschedule point in btrfs_find_all_roots() Btrfs: make send's file extent item search more efficient Btrfs: fix to catch all errors when resolving indirect ref Btrfs: fix protection between walking backrefs and root deletion btrfs: fix warning while merging two adjacent extents Btrfs: fix infinite path build loops in incremental send btrfs: undo sysfs when open_ctree() fails Btrfs: fix snprintf usage by send's gen_unique_name btrfs: fix defrag 32-bit integer overflow btrfs: sysfs: list the NO_HOLES feature btrfs: sysfs: don't show reserved incompat feature btrfs: call permission checks earlier in ioctls and return EPERM ...

Pull ubifs updates from Artem Bityutskiy: - Improve the NOR erasure quirk - now it tries to do as little writes as possible, because the eraseblock may be in an "unstable" state and write operation sometimes causes NOR chip lock-ups. - Both UBI and UBIFS changes are now maintainer in one single tree, because the amount of changes dropped significantly. * tag 'upstream-3.14-rc1' of git://git.infradead.org/linux-ubifs: UBI: avoid program operation on NOR flash after erasure interrupted MAINTAINERS: keep UBI and UBIFS stuff in the same tree UBI: fix error return code
