A few more fixes for this RC cycle. There's a revert of a previous patch which ended up being the wrong version, so we reverted that commit and applied a better fix. CPPI41 got a race condition fix which was found by Thomas Gleixner. The MSM PHY driver got a runtime pm usage fix so that it wouldn't kill the PHY while it was still being used. We also have a fix for a panic caused when removing musb_am335x driver. Other than that, a few other minor fixes.

This new ioctl call allows the user to supply a buffer of varying size in which a tree search can store its results. This is much more flexible if you want to receive items which are larger than the current fixed buffer of 3992 bytes or if you want to fetch more items at once. Items larger than this buffer are for example some of the type EXTENT_CSUM.

accounting, which improves the in-memory tracking of delayed extent

I had been working on Btrfs stack usage for a while, mostly because it

pagealloc debugging turned on without blowing the stack. Even though
you upgraded us to a nice king sized stack, I kept most of the
patches.

Pull nfsd updates from Bruce Fields:
"The largest piece is a long-overdue rewrite of the xdr code to remove
some annoying limitations: for example, there was no way to return
ACLs larger than 4K, and readdir results were returned only in 4k
chunks, limiting performance on large directories.
Also:
- part of Neil Brown's work to make NFS work reliably over the
loopback interface (so client and server can run on the same
machine without deadlocks). The rest of it is coming through
other trees.
- cleanup and bugfixes for some of the server RDMA code, from
Steve Wise.
- Various cleanup of NFSv4 state code in preparation for an
overhaul of the locking, from Jeff, Trond, and Benny.

This started as debugging helper, to watch the effects of converting between raid levels on multiple devices, but could be useful standalone. In my case the usage filter was not finegrained enough and led to converting too many chunks at once. Another example use is in connection with drange+devid or vrange filters that allow to work with a specific chunk or even with a chunk on a given device. The limit filter applies last, the value of 0 means no limiting.

System V shared memory
a) can be abused to trigger out-of-memory conditions and the standard
measures against out-of-memory do not work:
- it is not possible to use setrlimit to limit the size of shm segments.
- segments can exist without association with any processes, thus
the oom-killer is unable to free that memory.
b) is typically used for shared information - today often multiple GB.
(e.g. database shared buffers)
The current default is a maximum segment size of 32 MB and a maximum
total size of 8 GB. This is often too much for a) and not enough for
b), which means that lots of users must change the defaults.
This patch increases the default limits (nearly) to the maximum, which
is perfect for case b). The defaults are used after boot and as the
initial value for each new namespace.
Admins/distros that need a protection against a) should reduce the
limits and/or enable shm_rmid_forced.
Unix has historically required setting these limits for shared memory,
and Linux inherited such behavior. The consequence of this is added
complexity for users and administrators. One very common example are
Database setup/installation documents and scripts, where users must
manually calculate the values for these limits. This also requires
(some) knowledge of how the underlying memory management works, thus
causing, in many occasions, the limits to just be flat out wrong.
Disabling these limits sooner could have saved companies a lot of time,
headaches and money for support. But it's never too late, simplify
users life now.
Further notes:
- The patch only changes default, overrides behave as before:
# sysctl kernel.shmall=33554432
would recreate the previous limit for SHMMAX (for the current namespace).
- Disabling sysv shm allocation is possible with:
# sysctl kernel.shmall=0
(not a new feature, also per-namespace)
- The limits are intentionally set to a value slightly less than ULONG_MAX,
to avoid triggering overflows in user space apps.

perf tools like 'perf report' can aggregate samples by comm strings, which generally works. However, there are other potential use-cases. For example, to pair up 'calls' with 'returns' accurately (from branch events like Intel BTS) it is necessary to identify whether the process has exec'd. Although a comm event is generated when an 'exec' happens it is also generated whenever the comm string is changed on a whim (e.g. by prctl PR_SET_NAME). This patch adds a flag to the comm event to differentiate one case from the other. In order to determine whether the kernel supports the new flag, a selection bit named 'exec' is added to struct perf_event_attr. The bit does nothing but will cause perf_event_open() to fail if the bit is set on kernels that do not have it defined.

was a pretty active cycle for KVM. Changes include:
- a lot of s390 changes: optimizations, support for migration,
GDB support and more
- ARM changes are pretty small: support for the PSCI 0.2 hypercall
interface on both the guest and the host (the latter acked by Catalin)
- initial POWER8 and little-endian host support
- support for running u-boot on embedded POWER targets
- pretty large changes to MIPS too, completing the userspace interface
and improving the handling of virtualized timer hardware
- for x86, a larger set of changes is scheduled for 3.17. Still,
we have a few emulator bugfixes and support for running nested
fully-virtualized Xen guests (para-virtualized Xen guests have
always worked). And some optimizations too.
The only missing architecture here is ia64. It's not a coincidence
that support for KVM on ia64 is scheduled for removal in 3.17.

It is probably also the first one without a single patch from me. That is down to a combination of factors, and I have some things in the works that are not quite ready yet, that I hope to put in next time around. Returning to what is here this time... we have 3 patches which fix various warnings. Two are bug fixes (for quotas and also a rare recovery race condition). The final patch, from Ben Marzinski, is an important change in the freeze code which has been in progress for some time. This removes the need to take and drop the transaction lock for every single transaction, when the only time it was used, was at file system freeze time. Ben's patch integrates the freeze operation into the journal flush code as an alternative with lower overheads and also lands up resolving some difficult to fix races at the same time. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) iQIcBAABAgAGBQJTjawdAAoJEMrg3m4a/8jS+fEP/19pd9norrPgt+INKeWF3Nlj 0cCVyivBjjEOQseiokbn6AlO9sIBETCMsd3v/ke8haleR8J6F1K8OvRY2LV76vZT SKTae4Lts7Pzbf8JF9wSi3mpr3zhtQ47v6DvRYEylc68HcwM4EybaSKWEX3By2zd Xmhlv+v7V+PRYthaMalOXjhzuYA4Sv2BgdUGG9xKtIfzjvhHhzws/xBcr9UrotX2 oPjq08X9HY1TNuWN8tTs4P7BrOx8QCb7ZJzT2A9girFyVXNiduGTd11mzCguvHVQ /Ove3/7Cg3fABMg/3Ub2dpARqYxJRV25FlTV8RrOWj0BMhndWAbzMt1KPexk4FAE a3KCMBbo8WZbjRmOB4tmfknxDCdeUDAIlm1mwDPFJ1/0Vv8rkove1+xWHDvOPWD3 219GLiUe7PyVowBW4FQhW+CTjArqz3TWB+R/US18rXcwDS9s/vEIDVVwNYlrxRmK pztGMr25UoFhbvMe3jtu5xRwQM5oZfQtlYdL09+0BgkgPmuOtEwzuopa7g5MBAze Xq7h+oN8M4AtJs/msBF3di+fgOhUyoJmj129xgoZeCxbe80nA0ge0hnb93vQJHmE uHe4zV26ChGjUtxUwf77xOZfCEWKsp1ORJkFN+2SMcpUIlfNNumBv/UhrVRN55AO CneZaFLboYhxqc28K+Ms =x9iK -----END PGP SIGNATURE----- Merge tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw into next Pull gfs2 updates from Steven Whitehouse: "This must be about the smallest merge window patch set ever for GFS2.

Pull request: Fixes for new ethtool RSS commands
This addresses several problems I previously identified with the new
ETHTOOL_{G,S}RSSH commands:
1. Missing validation of reserved parameters
2. Vague documentation
3. Use of unnamed magic number
4. No consolidation with existing driver operations
I don't currently have access to suitable network hardware, but have
tested these changes with a dummy driver that can support various
combinations of operations and sizes, together with (a) Debian's ethtool
3.13 (b) ethtool 3.14 with the submitted patch to use ETHTOOL_{G,S}RSSH
and minor adjustment for fixes 1 and 3.

(This patch was previously posted as RFC at http://patchwork.ozlabs.org/patch/352677/) This patch adds NDA_MASTER attribute to neighbour attributes enum for bridge/master ifindex. And adds NDA_MASTER to bridge fdb notify msgs. Today bridge fdb notifications dont contain bridge information. Userspace can derive it from the port information in the fdb notification. However this is tricky in some scenarious. Example, bridge port delete notification comes before bridge fdb delete notifications. And we have seen problems in userspace when using libnl where, the bridge fdb delete notification handling code does not understand which bridge this fdb entry is part of because the bridge and port association has already been deleted. And these notifications (port membership and fdb) are generated on separate rtnl groups. Fixing the order of notifications could possibly solve the problem for some cases (I can submit a separate patch for that). This patch chooses to add NDA_MASTER to bridge fdb notify msgs because it not only solves the problem described above, but also helps userspace avoid another lookup into link msgs to derive the master index.

Noteworthy is the SB1 change which the result of changes to binutils resulting in one big gas warning for most files being assembled as well as the asid_cache and branch emulation fixes which fix corruption or possible uninteded behaviour of kernel or application code. The remainder of fixes are more platforms or subsystem specific" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: R46000: Fix Micro-assembler field overflow for R4600 V2 MIPS: ptrace: Avoid smp_processor_id() in preemptible code MIPS: Lemote 2F: cs5536: mfgpt: use raw locks MIPS: SB1: Fix excessive kernel warnings. MIPS: RC32434: fix broken PCI resource initialization MIPS: malta: memory.c: Initialize the 'memsize' variable MIPS: Fix typo when reporting cache and ftlb errors for ImgTec cores MIPS: Fix inconsistancy of __NR_Linux_syscalls value MIPS: Fix branch emulation of branch likely instructions. MIPS: Fix a typo error in AUDIT_ARCH definition MIPS: Change type of asid_cache to unsigned long

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next This small patchset contains three accumulated Netfilter/IPVS updates, they are: 1) Refactorize common NAT code by encapsulating it into a helper function, similarly to what we do in other conntrack extensions, from Florian Westphal. 2) A minor format string mismatch fix for IPVS, from Masanari Iida. 3) Add quota support to the netfilter accounting infrastructure, now you can add quotas to accounting objects via the nfnetlink interface and use them from iptables. You can also listen to quota notifications from userspace. This enhancement from Mathieu Poirier. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

In this round we have a few nice gems. PR KVM gains initial POWER8 support as well as LE host awareness, ihe e500 targets can now properly run u-boot, LE guests now work with PR KVM including KVM hypercalls and HV KVM guests can now use huge pages. On top of this there are some bug fixes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQIcBAABAgAGBQJTiHxMAAoJECszeR4D/txgGggQAL5rYpFkuU8+KiLd7uX4DasT DYrKxgOX/G8WRI0OJZpZHGdcw4fefBxHjY2ydnCSDk+EH2IPrlF6+aYnCwoarj3I L2Ji/OEfFZVgQtqNkqbuG5Z8onmrgZ86y5TFZKiMcDZe3zLnuGIP4fCLWEeWalor JQ9fE0z4WFkCtUD18/S/Cf6bOniGLdphUrmgECo+4SbSxUbixrckBEwuA7TjWure VrA0UX35l+VoVtYntKrQqYzsf+QSNWPzcDQnhlso+rz5ap6sB6rlC0PO8SHTPjk4 BXvHVvripVss7mGv7vZPizp52WXAFsNnVPj1tNSCu3Tn+gRBB8ChCV8xHIWYex8a nz8AvdUq1TdWmSy7NwJODjJfclauTVtrhPvrbLNSN3ksSzx4eLh8i+Lf8qe0SW7i 4oTfxG+PSDlF/ub8KX8BVfM0FpyvHdcR1h1ex3szPAQfiaAy+/ce9c3bB0xzXmLx sN3GX0BocdWejMo1U8+/+CVUngtol81BAb+k4GB5mPjW08u5jFVZu+XwxhK2ACx3 y3hAuaGd1d0YuTztYav7+wuu5gPwhYSA3/tmTR1+0jx9uCQbPpOyPJmprt/9A2DP TY0T0I3TUJqWZAtHOsY0P0hCGl+gZQJb8KhjVKHC6t6/ab3grMkpHgp9XDVvKpHJ u9lPDCuQRyJBSy9WI2Qa =t4YN -----END PGP SIGNATURE----- Merge tag 'signed-kvm-ppc-next' of git://github.com/agraf/linux-2.6 into kvm-next Patch queue for ppc - 2014-05-30 In this round we have a few nice gems.

We worked around some nasty KVM magic page hcall breakages: 1) NX bit not honored, so ignore NX when we detect it 2) LE guests swizzle hypercall instruction Without these fixes in place, there's no way it would make sense to expose kvm hypercalls to a guest. Chances are immensely high it would trip over and break. So add a new CAP that gives user space a hint that we have workarounds for the bugs above in place. It can use those as hint to disable PV hypercalls when the guest CPU is anything POWER7 or higher and the host does not have fixes in place. Signed-off-by: Alexander Graf <agraf@suse.de>

The file include/uapi/linux/usb/cdc-wdm.h uses a __u16 so it needs to
include types.h as well to make the build system happy.

The include/uapi/linux/usb/cdc-wdm.h header defines cdc-wdm
userspace APIs and should be exported by make headers_install.
