2012-12-05m68knommu: add clock creation support macro for other ColdFire CPUsGreg Ungerer
The clock support code for ColdFire CPUs currently supports those that have the clock control register PPMCR. Expose the struct clk for all CPU types and add a definition for all other ColdFire CPU types. With this we will be able to define simple clock trees for all ColdFire CPU types, even though they will not be able to be enabled or disabled. They will be able to report the clock rate.

2012-12-05m68k: fix unused variable warning in mempcy.cGreg Ungerer
When compiling for original 68000 or ColdFire targets you will get the following warning when compiling arch/m68k/lib/memcpy.c: CC arch/m68k/lib/memcpy.o arch/m68k/lib/memcpy.c: In function ‘__builtin_memcpy’: arch/m68k/lib/memcpy.c:13:15: warning: unused variable ‘temp1’ This is easily fixed by moving the definition of temp1 into the code block where it is used.

2012-12-05m68knommu: make non-MMU page_to_virt() return a void *Greg Ungerer
The page_to_virt() macro for m68knommu is currently effectively returning an int type. But the equivilent m68k macro returns a void * virtual address. Modify the non-MMU macro to return a void * as well (using the __va macro). This change will remove compiler warnings in common m68k code that use this macro.

2012-12-05m68knommu: merge ColdFire 5249 and 525x definitionsGreg Ungerer
The ColdFire 5249 and 525x family of SoCs are very similar. Most of the internals are the same, and are mapped the same. We can use a single set of peripheral definitions for all of them. So merge the current m5249sim.h and m525xsim.h definitions into a single file. The 5249 is now obsolete, and the 525x parts are current, so I have chosen to move everything into the existing m525xsim.h file. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

* pci/huang-d3cold-fixes: PCI/PM: Keep runtime PM enabled for unbound PCI devices
2012-12-04PCI/PM: Keep runtime PM enabled for unbound PCI devicesHuang Ying
For unbound PCI devices, what we need is: - Always in D0 state, because some devices do not work again after being put into D3 by the PCI bus. - In SUSPENDED state if allowed, so that the parent devices can still be put into low power state. To satisfy these requirements, the runtime PM for the unbound PCI devices are disabled and set to SUSPENDED state. One issue of this solution is that the PCI devices will be put into SUSPENDED state even if the SUSPENDED state is forbidden via the sysfs interface (.../power/control) of the device. This is not an issue for most devices, because most PCI devices are not used at all if unbound. But there are exceptions. For example, unbound VGA card can be used for display, but suspending its parents makes it stop working. To fix the issue, we keep the runtime PM enabled when the PCI devices are unbound. But the runtime PM callbacks will do nothing if the PCI devices are unbound. This way, we can put the PCI devices into SUSPENDED state without putting the PCI devices into D3 state.

In a couple of places we attempt to adjust the existing watermark registers to update them for the new cursor watermarks. This goes horribly wrong as instead of clearing the cursor bits prior to or'ing in the new values, we clear the rest of the register with the result that the watermark registers contain bogus values.

2012-12-04watchdog: Fix CPU hotplug regressionThomas Gleixner
Norbert reported: "3.7-rc6 booted with nmi_watchdog=0 fails to suspend to RAM or offline CPUs. It's reproducable with a KVM guest and physical system." The reason is that commit bcd951cf(watchdog: Use hotplug thread infrastructure) missed to take this into account. So the cpu offline code gets stuck in the teardown function because it accesses non initialized data structures. Add a check for watchdog_enabled into that path to cure the issue.

2012-12-04clk: ux500: fix bit errorLinus Walleij
This fixes a bit error in the U8500 clock implementation: the unused p2_pclk12 registered at bit 12 in periphereral group 6 was defined as using bit 11 rather than bit 12. When walking over and disabling the unused clocks in the tree at late init time, p2_pclk12 was disabled, by effectively clearing the but for p2_pclk11 instead of bit 12 as it should have, thus disabling gpio block 6 and 7.

2012-12-04net: dev_change_net_namespace: send a KOBJ_REMOVED/KOBJ_ADDSerge Hallyn
When a new nic is created in namespace ns1, the kernel sends a KOBJ_ADD uevent to ns1. When the nic is moved to ns2, we only send a KOBJ_MOVE to ns2, and nothing to ns1. This patch changes that behavior so that when moving a nic from ns1 to ns2, we send a KOBJ_REMOVED to ns1 and KOBJ_ADD to ns2. (The KOBJ_MOVE is still sent to ns2). The effects of this can be seen when starting and stopping containers in an upstart based host. Lxc will create a pair of veth nics, the kernel sends KOBJ_ADD, and upstart starts network-instance jobs for each. When one nic is moved to the container, because no KOBJ_REMOVED event is received, the network-instance job for that veth never goes away. This was reported at https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1065589 With this patch the networ-instance jobs properly go away. The other oddness solved here is that if a nic is passed into a running upstart-based container, without this patch no network-instance job is started in the container. But when the container creates a new nic itself (ip link add new type veth) then network-interface jobs are created. With this patch, behavior comes in line with a regular host. v2: also send KOBJ_ADD to new netns. There will then be a _MOVE event from the device_rename() call, but that should be innocuous.

/proc/net/ip[6]_mr_cache allows to get all mfc entries, even if they are put in the unresolved list (mfc[6]_unres_queue). But only the table RT_TABLE_DEFAULT is displayed. This patch adds the parsing of the unresolved list when the dump is made via rtnetlink, hence each table can be checked. In IPv6, we set rtm_type in ip6mr_fill_mroute(), because in case of unresolved mfc __ip6mr_fill_mroute() will not set it. In IPv4, it is already done.

Now ct objects are always placed in any of the existing lists.

Commit 8852aac25e79 ("workqueue: mod_delayed_work_on() shouldn't queue timer on 0 delay") had the side-effect of performing delayed_work sanity checks even when @delay is 0, which should be fine for any sane use cases. Unfortunately, megaraid was being overly ingenious. It seemingly wanted to use cancel_delayed_work_sync() before cancel_work_sync() was introduced, but didn't want to waste the space for full delayed_work as it was only going to use 0 @delay. So, it only allocated space for struct work_struct and then cast it to struct delayed_work and passed it into delayed_work functions - truly awesome engineering tradeoff to save some bytes. Xiaotian fixed it by making megraid allocate full delayed_work for now. It should be converted to use work_struct and cancel_work_sync() but I think we better do that after 3.7.
