They vary from being able to deal with unknown requests, overflow in statistics, compile warnings, bug in the error path, removal of unnecessary logic. There is also one performance fix - which is to allocate pages for requests when the driver loads - instead of doing it per request
2013-03-22tcp: preserve ACK clocking in TSOEric Dumazet
A long standing problem with TSO is the fact that tcp_tso_should_defer() rearms the deferred timer, while it should not.

2013-03-22decnet: Parse netlink attributes on our ownThomas Graf
decnet is the only subsystem left that is relying on the global netlink attribute buffer rta_buf. It's horrible design and we want to get rid of it. This converts all of decnet to do implicit attribute parsing. It also gets rid of the error prone struct dn_kern_rta. Yes, the fib_magic() stuff is not pretty. It's compiled tested but I need someone with appropriate hardware to test the patch since I don't have access to it.

2013-03-22Merge branch 'mv643xx_eth'David S. Miller
Florian Fainelli says: ==================== This patch converts the mv643xx_eth driver to use the mvmdio MDIO bus driver instead of rolling its own implementation. As a result, all users of this mv643xx_eth driver are converted to register an "orion-mdio" platform_device. The mvmdio driver is also updated to support an interrupt line which reports SMI error/completion, and to allow traditionnal platform device registration instead of just device tree. David, I think it makes sense for you to merge all of this, since we do not want the architecture files to be desynchronized from the mv643xx_eth to avoid runtime breakage. The potential for merge conflicts should be very small. ==================== Tested-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Tested-by: Jason Cooper <jason@lakedaemon.net> Acked-by: Jason Cooper <jason@lakedaemon.net> Signed-off-by: David S.

2013-03-22mv643xx_eth: convert to use the Marvell Orion MDIO driverFlorian Fainelli
This patch converts the Marvell MV643XX ethernet driver to use the Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms registering the Marvell MV643XX ethernet driver are also updated to register a Marvell Orion MDIO driver. This driver voluntarily overlaps with the Marvell Ethernet shared registers because it will use a subset of this shared register (shared_base + 0x4 to shared_base + 0x84). The Ethernet driver is also updated to look up for a PHY device using the Orion MDIO bus driver. For ARM and PowerPC we register a single instance of the "mvmdio" driver in the system like it used to be done with the use of the "shared_smi" platform_data cookie on ARM. Note that it is safe to register the mvmdio driver only for the "ge00" instance of the driver because this "ge00" interface is guaranteed to always be explicitely registered by consumers of arch/arm/plat-orion/common.c and other instances (ge01, ge10 and ge11) were all pointing their shared_smi to ge00. For PowerPC the in-tree Device Tree Source files mention only one MV643XX ethernet MAC instance so the MDIO bus driver is registered only when id == 0.

2013-03-22net: mvmdio: enhance driver to support SMI error/done interruptsFlorian Fainelli
This patch enhances the "mvmdio" to support a SMI error/done interrupt line which can be used along with a wait queue instead of doing busy-waiting on the registers. This is a feature which is available in the mv643xx_eth SMI code and thus reduces again the gap between the two. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-03-22net: mvmdio: rename base register cookie from smireg to regsFlorian Fainelli
This patch renames the base register cookie in the mvmdio drive from "smireg" to "regs" since a subsequent patch is going to use an ioremap() cookie whose size is larger than a single register of 4 bytes. No functionnal code change introduced. Acked-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S.

2013-03-22net: mvmdio: allow platform device style registrationFlorian Fainelli
This patch changes the mvmdio driver not to use device tree helper functions such as of_mdiobus_register() and of_iomap() so we can instantiate this driver using a classic platform_device approach. Use the device manager helper to ioremap() the base register cookie so we get automatic freeing upon error and removal. This change is harmless for Device Tree platforms because they will get the driver be registered the same way as it was before.

2013-03-22xen-pciback: notify hypervisor about devices intended to be assigned to guestsJan Beulich
For MSI-X capable devices the hypervisor wants to write protect the MSI-X table and PBA, yet it can't assume that resources have been assigned to their final values at device enumeration time. Thus have pciback do that notification, as having the device controlled by it is a prerequisite to assigning the device to guests anyway. This is the kernel part of hypervisor side commit 4245d33 ("x86/MSI: add mechanism to fully protect MSI-X table from PV guest accesses") on the master branch of git://xenbits.xen.org/xen.git.

2013-03-22xen/acpi-processor: Don't dereference struct acpi_processor on all CPUs.Konrad Rzeszutek Wilk
With git commit c705c78c0d0835a4aa5d0d9a3422e3218462030c "acpi: Export the acpi_processor_get_performance_info" we are now using a different mechanism to access the P-states. The acpi_processor per-cpu structure is set and filtered by the core ACPI code which shrinks the per_cpu contents to only online CPUs. In the past we would call acpi_processor_register_performance() which would have not tried to dereference offline cpus. With the new patch and the fact that the loop we take is for for_all_possible_cpus we end up crashing on some machines. We could modify the loop to be for online_cpus - but all the other loops in the code use possible_cpus (for a good reason) - so lets leave it as so and just check if per_cpu(processor) is NULL. With this patch we will bypass the !online but possible CPUs.

2013-03-21Merge tag 'efi-for-3.9-rc3' into x86/urgentH. Peter Anvin
EFI changes for v3.9-rc3, * A new config option and efivars module parameter have been added to allow the efivars pstore backend to be disabled as we're still seeing issues on machines despite adding heuristics to workaround known bugs. Distributions now have a way to disable EFI variable pstore code completely - from Seth Forshee. * A couple of efivars patches to workaround quirky implementations of GetNextVariableName() which resulted in machines hanging and sysfs files being created with garbage names.

2013-03-21Btrfs: fix locking on ROOT_REPLACE operations in tree mod logJan Schmidt
To resolve backrefs, ROOT_REPLACE operations in the tree mod log are required to be tied to at least one KEY_REMOVE_WHILE_FREEING operation. Therefore, those operations must be enclosed by tree_mod_log_write_lock() and tree_mod_log_write_unlock() calls. Those calls are private to the tree_mod_log_* functions, which means that removal of the elements of an old root node must be logged from tree_mod_log_insert_root. This partly reverts and corrects commit ba1bfbd5 (Btrfs: fix a tree mod logging issue for root replacement operations). This fixes the brand-new version of xfstest 276 as of commit cfe73f71.

2013-03-21Btrfs: fix missing qgroup reservation before fallocatingWang Shilong
Steps to reproduce: mkfs.btrfs <disk> mount <disk> <mnt> btrfs quota enable <mnt> btrfs sub create <mnt>/subv btrfs qgroup limit 10M <mnt>/subv fallocate --length 20M <mnt>/subv/data For the above example, fallocating will return successfully which is not expected, we try to fix it by doing qgroup reservation before fallocating.

2013-03-21Btrfs: handle a bogus chunk tree nicelyJosef Bacik
If you restore a btrfs-image file system and try to mount that file system we'll panic. That's because btrfs-image restores and just makes one big chunk to envelope the whole disk, since they are really only meant to be messed with by our btrfs-progs. So fix up btrfs_rmap_block and the callers of it for mount so that we no longer panic but instead just return an error and fail to mount.
