1) Setting link attributes can modify the size of the attributes that would be reported on a subsequent getlink netlink operation, therefore min_ifinfo_dump_size needs to be adjusted. From Stefan Gula. 2) Resegmentation of TSO frames while trimming can violate invariants expected by callers, namely that the number of segments can only stay the same or decrease, never increase. If MSS changes, however, we can trim data but then end up with more segments. Fix this by only segmenting to the MSS already recorded in the SKB. That's the simplest fix for now and if we want to get more fancy in the future that's a more involved change. This probably explains some retransmit counter inaccuracies. From Neal Cardwell. 3) Fix too-many-wakeups in POLL with AF_UNIX sockets, from Eric Dumazet. 4) Fix CAIF crashes wrt. namespace handling. From Eric Dumazet and Eric W. Biederman. 5) TCP port selection fixes from Flavio Leitner. 6) More socket memory cgroup build fixes in certain randonfig situations. From Glauber Costa. 7) Fix TCP memory sysctl regression reported by Ingo Molnar, also from Glauber Costa. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: af_unix: fix EPOLLET regression for stream sockets tcp: fix tcp_trim_head() to adjust segment count with skb MSS net/tcp: Fix tcp memory limits initialization when !CONFIG_SYSCTL net caif: Register properly as a pernet subsystem. netns: Fail conspicously if someone uses net_generic at an inappropriate time. net: explicitly add jump_label.h header to sock.h net: RTNETLINK adjusting values of min_ifinfo_dump_size ipv6: Fix ip_gre lockless xmits. xen-netfront: correct MAX_TX_TARGET calculation. netns: fix net_alloc_generic() tcp: bind() optimize port allocation tcp: bind() fix autoselection to share ports l2tp: l2tp_ip - fix possible oops on packet receive iwlwifi: fix PCI-E transport "inta" race mac80211: set bss_conf.idle when vif is connected mac80211: update oper_channel on ibss join

2012-01-30vmwgfx: Fix assignment in vmw_framebuffer_create_handleRyan Mallon
The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.

This reverts commit 87499ffdcb1c70f66988cd8febc4ead0ba2f9118. Where is that paper bag ... ah here. I've failed to take an odd interaction between my other cleanups and this reclaim_buffers patch into account and also failed to properly test it.

2012-01-26USB/PCI/PCMCIA: Clean up new_id and remove_id sysfs attribute routinesAlan Stern
This patch (as1514) cleans up some places where new_id and remove_id sysfs attributes are created and deleted. Handling both attributes in a single routine rather than a pair of routines makes the code smaller. It also prevents certain kinds of errors, like one we currently have in the USB subsystem: The removeid attribute is often created even when newid isn't (because the driver's no_dynamid_id flag is set). In the case of the PCMCIA subsystem, the newid attribute is created but never explicitly deleted. The patch adds a deletion routine.

2012-01-26CPU: Introduce ARCH_HAS_CPU_AUTOPROBE and X86 partsThomas Renninger
This patch is based on Andi Kleen's work: Implement autoprobing/loading of modules serving CPU specific features (x86cpu autoloading). And Kay Siever's work to get rid of sysdev cpu structures and making use of struct device instead. Before, the cpuid driver had to be loaded to get the x86cpu autoloading feature.

2012-01-26cpufreq: Add support for x86 cpuinfo auto loading v4Andi Kleen
This marks all the x86 cpuinfo tables to the CPU specific device drivers, to allow auto loading by udev. This should simplify the distribution startup scripts for this greatly. I didn't add MODULE_DEVICE_IDs to the centrino and p4-clockmod drivers, because those probably shouldn't be auto loaded and the acpi driver be used instead (not fully sure on that, would appreciate feedback) The old nforce drivers autoload based on the PCI ID. ACPI cpufreq is autoloaded in another patch. v3: Autoload gx based on PCI IDs only.
