2010-12-17connector: Use this_cpu operationsChristoph Lameter
The patch was originally in the use cpuops patchset but it needs an inc_return and is therefore dependent on an extension of the cpu ops. Fixed up and verified that it compiles. get_seq can benefit from this_cpu_operations. Address calculation is avoided and the increment is done using an xadd.

2010-12-17ARM: mach-shmobile: INTC interrupt priority level demux fixMagnus Damm
Fix interrupt priority level handling on SH-Mobile ARM. SH-Mobile ARM platforms using multiple interrupt priority levels need this patch to fix a potential dead lock that may occur if multiple interrupts with different levels are pending simultaneously. The default INTC configuration is to use the same priority level for all interrupts, so this issue does not trigger by default. It is however common for board code to override the interrupt priority for certain interrupt sources depending on the application. Without this fix such boards may lock up. In detail, this patch updates the INTC code in entry-macro.S to make sure that the INTLVLA register gets set as expected. To trigger this bug modify the board specific code to adjust the interrupt priority level for the ethernet chip. After changing the priority level simply use flood ping to drown the board with interrupts. This patch applies to INTCA-based processors such as sh7372, sh7377 and sh7372. GIC-based processors are not affected. Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.

2010-12-17block: Deprecate QUEUE_FLAG_CLUSTER and use queue_limits insteadMartin K. Petersen
When stacking devices, a request_queue is not always available. This forced us to have a no_cluster flag in the queue_limits that could be used as a carrier until the request_queue had been set up for a metadevice. There were several problems with that approach. First of all it was up to the stacking device to remember to set queue flag after stacking had completed. Also, the queue flag and the queue limits had to be kept in sync at all times. We got that wrong, which could lead to us issuing commands that went beyond the max scatterlist limit set by the driver. The proper fix is to avoid having two flags for tracking the same thing. We deprecate QUEUE_FLAG_CLUSTER and use the queue limit directly in the block layer merging functions. The queue_limit 'no_cluster' is turned into 'cluster' to avoid double negatives and to ease stacking. Clustering defaults to being enabled as before. The queue flag logic is removed from the stacking function, and explicitly setting the cluster flag is no longer necessary in DM and MD.

2010-12-16x86-32: Make sure we can map all of lowmem if we need toH. Peter Anvin
A relocatable kernel can be anywhere in lowmem -- and in the case of a kdump kernel, is likely to be fairly high. Since the early page tables map everything from address zero up we need to make sure we allocate enough brk that we can map all of lowmem if we need to.

2010-12-16ipv6: don't flush routes when setting loopback downstephen hemminger
When loopback device is being brought down, then keep the route table entries because they are special. The entries in the local table for linklocal routes and ::1 address should not be purged. This is a sub optimal solution to the problem and should be replaced by a better fix in future. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Acked-by: "Eric W.

2010-12-16tty: add 'active' sysfs attribute to tty0 and console deviceKay Sievers
tty: add 'active' sysfs attribute to tty0 and console device Userspace can query the actual virtual console, and the configured console devices behind /dev/tt0 and /dev/console. The last entry in the list of devices is the active device, analog to the console= kernel command line option. The attribute supports poll(), which is raised when the virtual console is changed or /dev/console is reconfigured.

This reverts commit 1ab83238740ff1e1773d5c13ecac43c60cf4aec4. Turns out this doesn't allow for the device ids to be overridden properly, so we need to revert the thing.
