2011-10-17ARM: 7029/1: Make cpu_architecture into a global variableDave Martin
The CPU architecture really should not be changing at runtime, so make it a global variable instead of a function. The cpu_architecture() function declared in <asm/system.h> remains the correct way to read this variable from C code.

2011-10-17ARM: 7022/1: allow to detect conflicting zreladdrsSascha Hauer
Boards used to specify zreladdr in their Makefile.boot with zreladdr-y := x, so conflicting zreladdrs were silently overwritten. This patch changes this to zreladdr-y += x, so that we end up with multiple words in zreladdr in such a case. We can detect this later and complain if necessary.

2011-10-17ARM: 7023/1: L2x0: Add interrupts property to OF bindingMark Rutland
Following the discussion here: http://lists.ozlabs.org/pipermail/devicetree-discuss/2011-August/007301.html The L2x0 L2 Cache Controllers support a combined interrupt line which can be used for several events (e.g. read/write/parity errors on tag/data RAM, event counter increment/overflow). Unfortunately the OF binding added in c519ecf2 ("ARM: 7009/1: l2x0: Add OF based initialization") does not represent the interrupt. This patch adds an "interrupts" property to the L2x0 OF binding, representing the combined interrupt line.

2011-10-17ARM: 7073/1: debug: augment DEBUG_LL Kconfig help to clarify behaviourWill Deacon
Enabled DEBUG_LL hardcodes the UART address into the kernel and results in a non-portable kernel image. Since this option is only intended for use when debugging early boot failures, supporting multiple platforms in such a configuration is not the intended use-case.

2011-10-17ARM: 7072/1: debug: use kconfig choice for selecting DEBUG_LL UARTWill Deacon
Enabling CONFIG_DEBUG_LL (which is required for earlyprintk) hardwires the debug UART address into the kernel, so that we can print before the platform is initialised. If the user inadvertently selects multiple platforms with DEBUG_LL enabled, the UART address may not be correct and will likely cause the kernel to hang in the very early stages of boot. This patch, based on a skeleton from Russell, uses a Kconfig choice for selecting the DEBUG_LL UART, therefore allowing the user to make a choice about the supported platform when DEBUG_LL is enabled.

2011-10-16PM / Freezer: Make fake_signal_wake_up() wake TASK_KILLABLE tasks tooJeff Layton
TASK_KILLABLE is often used to put tasks to sleep for quite some time. One of the most common uses is to put tasks to sleep while waiting for replies from a server on a networked filesystem (such as CIFS or NFS). Unfortunately, fake_signal_wake_up does not currently wake up tasks that are sleeping in TASK_KILLABLE state. This means that even if the code were in place to allow them to freeze while in this sleep, it wouldn't work anyway. This patch changes this function to wake tasks in this state as well. This should be harmless -- if the code doing the sleeping doesn't have handling to deal with freezer events, it should just go back to sleep. If it does, then this will allow that code to do the right thing. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

2011-10-16PM / Hibernate: Add resumewait param to support MMC-like devices as resume fileBarry Song
Some devices like MMC are async detected very slow. For example, drivers/mmc/host/sdhci.c launches a 200ms delayed work to detect MMC partitions then add disk. We have wait_for_device_probe() and scsi_complete_async_scans() before calling swsusp_check(), but it is not enough to wait for MMC. This patch adds resumewait kernel param just like rootwait so that we have enough time to wait until MMC is ready. The difference is that we wait for resume partition whereas rootwait waits for rootfs partition (which may be on a different device). This patch will make hibernation support many embedded products without SCSI devices, but with devices like MMC.

2011-10-16PM / Hibernate: Freeze kernel threads after preallocating memoryRafael J. Wysocki
There is a problem with the current ordering of hibernate code which leads to deadlocks in some filesystems' memory shrinkers. Namely, some filesystems use freezable kernel threads that are inactive when the hibernate memory preallocation is carried out. Those same filesystems use memory shrinkers that may be triggered by the hibernate memory preallocation. If those memory shrinkers wait for the frozen kernel threads, the hibernate process deadlocks (this happens with XFS, for one example). Apparently, it is not technically viable to redesign the filesystems in question to avoid the situation described above, so the only possible solution of this issue is to defer the freezing of kernel threads until the hibernate memory preallocation is done, which is implemented by this change. Unfortunately, this requires the memory preallocation to be done before the "prepare" stage of device freeze, so after this change the only way drivers can allocate additional memory for their freeze routines in a clean way is to use PM notifiers.

2011-10-16PM / Suspend: Add statistics debugfs file for suspend to RAMShuoX Liu
Record S3 failure time about each reason and the latest two failed devices' names in S3 progress. We can check it through 'suspend_stats' entry in debugfs. The motivation of the patch: We are enabling power features on Medfield. Comparing with PC/notebook, a mobile enters/exits suspend-2-ram (we call it s3 on Medfield) far more frequently. If it can't enter suspend-2-ram in time, the power might be used up soon. We often find sometimes, a device suspend fails. Then, system retries s3 over and over again. As display is off, testers and developers don't know what happens. Some testers and developers complain they don't know if system tries suspend-2-ram, and what device fails to suspend. They need such info for a quick check. The patch adds suspend_stats under debugfs for users to check suspend to RAM statistics quickly. If not using this patch, we have other methods to get info about what device fails. One is to turn on CONFIG_PM_DEBUG, but users would get too much info and testers need recompile the system. In addition, dynamic debug is another good tool to dump debug info. But it still doesn't match our utilization scenario closely. 1) user need write a user space parser to process the syslog output; 2) Our testing scenario is we leave the mobile for at least hours. Then, check its status. No serial console available during the testing. One is because console would be suspended, and the other is serial console connecting with spi or HSU devices would consume power. These devices are powered off at suspend-2-ram.

2011-10-16[SCSI] lpfc 8.3.27: Fix queue allocation failure recoveryJames Smart
Fix queue allocation failure recovery - Move the allocation of the Queues closer to the creation of the queues. - If there is a problem with creation, or if the HBA is reset, the queues will be completely freed and re allocated. - Only allocate fcp_eq_hdl if cfg_fcp_eq_count is non-zero.
