nfs3_proc_setacls is used internally by the NFSv3 create operations to set the acl after the file has been created. If the operation fails because the server doesn't support acls, then it must return '0', not -EOPNOTSUPP. Reported-by:

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. Cc: stable@vger.kernel.org Signed-off-by:

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. Reported-by:

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. Signed-off-by:

The grant mapping API does m2p_override unnecessarily: only gntdev needs it, for blkback and future netback patches it just cause a lock contention, as those pages never go to userspace. 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:

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.

The x32 case for the recvmsg() timout handling is broken: asmlinkage long compat_sys_recvmmsg(int fd, struct compat_mmsghdr __user *mmsg, unsigned int vlen, unsigned int flags, struct compat_timespec __user *timeout) { int datagrams; struct timespec ktspec; if (flags & MSG_CMSG_COMPAT) return -EINVAL; if (COMPAT_USE_64BIT_TIME) return __sys_recvmmsg(fd, (struct mmsghdr __user *)mmsg, vlen, flags | MSG_CMSG_COMPAT, (struct timespec *) timeout); ... The timeout pointer parameter is provided by userland (hence the __user annotation) but for x32 syscalls it's simply cast to a kernel pointer and is passed to __sys_recvmmsg which will eventually directly dereference it for both reading and writing. Other callers to __sys_recvmmsg properly copy from userland to the kernel first. The bug was introduced by commit ee4fa23c ("compat: Use COMPAT_USE_64BIT_TIME in net/compat.c") and should affect all kernels since 3.4 (and perhaps vendor kernels if they backported x32 support along with this code). Note that CONFIG_X86_X32_ABI gets enabled at build time and only if CONFIG_X86_X32 is enabled and ld can build x32 executables. Other uses of COMPAT_USE_64BIT_TIME seem fine. This addresses CVE-2014-0038. Signed-off-by:

Pull x86 asmlinkage (LTO) changes from Peter Anvin: "This patchset adds more infrastructure for link time optimization (LTO).

Pull x86 build bits from Peter Anvin: "Various build-related minor bits. Most of this is work by David Woodhouse to be able to compile the early boot code with clang/llvm; we have also managed to push an actual -m16 option into gcc 4.9 so this makes us use that option if available instead of hacking it. The balance is a patch from Michael Davidson to the relocs program to help manual debugging. None of these should change the actual compiled binary with currently released compilers" * 'x86-build-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, build: Build 16-bit code with -m16 where possible x86, boot: Fix word-size assumptions in has_eflag() inline asm x86, boot: Use __attribute__((used)) to ensure videocard structs are emitted x86: Remove duplication of 16-bit CFLAGS x86, relocs: Add manual debug mode

Pull MIPS updates from Ralf Baechle: "The most notable new addition inside this pull request is the support for MIPS's latest and greatest core called "inter/proAptiv". The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree.
