2012-10-23ARM: OMAP3: Beagle: fix OPP customization and initcall orderingKevin Hilman1-9/+13
After commit 24d7b40a60cf19008334bcbcbd98da374d4d9c64 (ARM: OMAP2+: PM: MPU DVFS: use generic CPU device for MPU-SS), OPPs are registered using an existing CPU device, not the omap_device for MPU-SS. First, fix the board file to use get_cpu_device() as required by the above commit, otherwise custom OPPs will be added to the wrong device. Second, the board files OPP init is called from the its init_machine method, and the generic CPU devices are not yet created when init_machine is run. Therefore OPP initialization will fail. To fix, use a device_initcall() for the board file's OPP customization, and make the device_initcall board-specific by using a machine_is check.

2012-10-23ARM: OMAP3: Fix 3430 legacy mux names for ssi1 signals.Tony Lindgren1-4/+4
On n900 uart1 pins are not not used for uart, instead they are used to connect to a cell modem over ssi. Looks like we're currently missing these signal names for 3430 for some reason, and only have some of them listed for 3630. Obviously the signals are there for 3430 if n900 is using them and they are documented in some TRMs. Note that these will eventually be replaced by device tree based pinctrl-single.c driver. But for now these are needed to verify the SSI pins for devices like Nokia N900. Signed-off-by: Tony Lindgren <tony@atomide.com>

The missing sidetone hwmod link will prevent omap_device_alloc() to append the DMA resources since we - accidentally - end up having the same number of resources provided from DT (IO/IRQ) as we have in hwmod for the McBSP ports without the ST resources.

2012-10-23ARM: OMAP2: UART: fix console UART mismatched runtime PM statusKevin Hilman1-0/+5
The runtime PM framework assumes that the hardware state of devices when initialized is disabled. For all omap_devices, we idle/disable device by default. However, the console uart uses a "no idle" option during omap_device init in order to allow earlyprintk usage to work seamlessly during boot. Because the hardware is left partially enabled after init (whatever the bootloader settings were), the omap_device should later be fully initialized (including mux) and the runtime PM framework should be told that the device is active, and not disabled so that the hardware state is in sync with runtime PM state. To fix, after the device has been created/registered, call omap_device_enable() to finialize init and use pm_runtime_set_active() to tell the runtime PM core the device is enabled. Tested on 2420/n810, 3530/Overo, 3530/Beagle, 3730/OveroSTORM, 3730/Beagle-xM, 4460/PandaES.

2012-10-23ARM: OMAP3: PM: apply part of the erratum i582 workaroundPaul Walmsley2-2/+29
On OMAP34xx/35xx, and OMAP36xx chips with ES < 1.2, if the PER powerdomain goes to OSWR or OFF while CORE stays at CSWR or ON, or if, upon chip wakeup from OSWR or OFF, the CORE powerdomain goes ON before PER, the UART3/4 FIFOs and McBSP2/3 SIDETONE memories will be unusable. This is erratum i582 in the OMAP36xx Silicon Errata document. This patch implements one of several parts of the workaround: the addition of the wakeup dependency between the PER and WKUP clockdomains, such that PER will wake up at the same time CORE_L3 does. This is not a complete workaround. For it to be complete: 1. the PER powerdomain's next power state must not be set to OSWR or OFF if the CORE powerdomain's next power state is set to CSWR or ON; 2. the UART3/4 FIFO and McBSP2/3 SIDETONE loopback tests should be run if the LASTPOWERSTATEENTERED bits for PER and CORE indicate that PER went OFF while CORE stayed on. If loopback tests fail, then those devices will be unusable until PER and CORE can undergo a transition from ON to OSWR/OFF and back ON.

2012-10-20arm64: fix alignment padding in assembly codeMarc Zyngier2-1/+7
An interesting effect of using the generic version of linkage.h is that the padding is defined in terms of x86 NOPs, which can have even more interesting effects when the assembly code looks like this: ENTRY(func1) mov x0, xzr ENDPROC(func1) // fall through ENTRY(func2) mov x0, #1 ret ENDPROC(func2) Admittedly, the code is not very nice. But having code from another architecture doesn't look completely sane either. The fix is to add arm64's version of linkage.h, which causes the insertion of proper AArch64 NOPs.

2012-10-20MODSIGN: Move the magic string to the end of a module and eliminate the searchDavid Howells4-31/+28
Emit the magic string that indicates a module has a signature after the signature data instead of before it. This allows module_sig_check() to be made simpler and faster by the elimination of the search for the magic string. Instead we just need to do a single memcmp(). This works because at the end of the signature data there is the fixed-length signature information block. This block then falls immediately prior to the magic number. From the contents of the information block, it is trivial to calculate the size of the signature data and thus the size of the actual module data.

Turn sign-file into perl and merge in x509keyid. The latter doesn't need to be a separate script as it doesn't actually need to work out the SHA1 sum of the X.509 certificate itself, since it can get that from the X.509 certificate.

2012-10-20hold task->mempolicy while numa_maps scans.KAMEZAWA Hiroyuki2-3/+51
/proc/<pid>/numa_maps scans vma and show mempolicy under mmap_sem. It sometimes accesses task->mempolicy which can be freed without mmap_sem and numa_maps can show some garbage while scanning. This patch tries to take reference count of task->mempolicy at reading numa_maps before calling get_vma_policy(). By this, task->mempolicy will not be freed until numa_maps reaches its end. V2->v3 - updated comments to be more verbose. - removed task_lock() in numa_maps code. V1->V2 - access task->mempolicy only once and remember it. Becase kernel/exit.c can overwrite it.

If there is only one match, the unique matched entry should be returned. Without the fix, the upcoming dma debug interfaces ("dma-debug: new interfaces to debug dma mapping errors") can't work reliably because only device and dma_addr are passed to dma_mapping_error().

2012-10-20mm: compaction: correct the nr_strict va isolated check for CMAMel Gorman1-1/+1
Thierry reported that the "iron out" patch for isolate_freepages_block() had problems due to the strict check being too strict with "mm: compaction: Iron out isolate_freepages_block() and isolate_freepages_range() -fix1". It's possible that more pages than necessary are isolated but the check still fails and I missed that this fix was not picked up before RC1. This same problem has been identified in 3.7-RC1 by Tony Prisk and should be addressed by the following patch.

2012-10-20pidns: remove recursion from free_pid_ns()Cyrill Gorcunov2-14/+15
free_pid_ns() operates in a recursive fashion: free_pid_ns(parent) put_pid_ns(parent) kref_put(&ns->kref, free_pid_ns); free_pid_ns thus if there was a huge nesting of namespaces the userspace may trigger avalanche calling of free_pid_ns leading to kernel stack exhausting and a panic eventually. This patch turns the recursion into an iterative loop. Based on a patch by Andrew Vagin.
