Fix up trivial conflicts in fs/xfs/linux-2.6/xfs_super.c due to the new shrinker callout for the inode cache, that clashed with the xfs code to start the periodic workers later.

| * | | perf: Add context field to perf_eventAvi Kivity2011-07-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The perf_event overflow handler does not receive any caller-derived argument, so many callers need to resort to looking up the perf_event in their local data structure. This is ugly and doesn't scale if a single callback services many perf_events. Fix by adding a context parameter to perf_event_create_kernel_counter() (and derived hardware breakpoints APIs) and storing it in the perf_event. The field can be accessed from the callback as event->overflow_handler_context. All callers are updated.

| * | | perf, arch: Add generic NODE cache eventsPeter Zijlstra2011-07-013-0/+70

Like all other cache events, an ACCESS is HIT+MISS, if there is no way to distinguish between reads and writes do reads only etc.. The below needs filling out for !x86 (which I filled out with unsupported events). I'm fairly sure ARM can leave it like that since it doesn't strike me as an architecture that even has NUMA support. SH might have something since it does appear to have some NUMA bits. Sparc64, PowerPC and MIPS certainly want a good look there since they clearly are NUMA capable.

| * | | perf: Remove the nmi parameter from the swevent and overflow interfacePeter Zijlstra2011-07-016-9/+9

For the various event classes: - hardware: nmi=0; PMI is in fact an NMI or we run irq_work_run from the PMI-tail (ARM etc.) - tracepoint: nmi=0; since tracepoint could be from NMI context. - software: nmi=[0,1]; some, like the schedule thing cannot perform wakeups, and hence need 0. As one can see, there is very little nmi=1 usage, and the down-side of not using it is that on some platforms some software events can have a jiffy delay in wakeup (when arch_irq_work_raise isn't implemented). The up-side however is that we can remove the nmi parameter and save a bunch of conditionals in fast paths.

If an omap_device has not already been runtime suspended, the ->suspend_noirq() method of the PM domain will use omap_device_idle() to idle the HW after calling the driver's ->runtime_suspend() callback. Similarily, upon resume, if the device was suspended during ->suspend_noirq(), the ->resume_noirq() method of the PM domain will use omap_device_enable() to enable the HW and then call the driver's ->runtime_resume() callback. If a device has already been runtime suspended, the noirq methods of the PM domain leave the device runtime suspended by default. However, if a driver needs to runtime resume a device during suspend (for example, to change its wakeup settings), it may do so using pm_runtime_get* in it's ->suspend() callback.

The sh7372 data sheet mentions that the VPU is located in the A3RV power domain. The A3RV power domain is not related to A4LC in any way, but testing shows that unless A3RV _and_ A4LC are powered on the VPU test program will bomb out. This issue may be caused by a more or less undocumented dependency on the MERAM block that happens to be located in A4LC. So now we know that the out-of-reset requirement of the VPU is that the MERAM is powered on. This patch adds a workaround for A3RV to make sure A4LC is powered on - this so we can use the VPU even though the LCDCs are in blanking state and A4LC is supposed to be off.

Namely, at the kernel level, a struct dev_power_domain object can represent arbitrary set of devices that are mutually dependent power management-wise and need not belong to one hardware power domain. To avoid that confusion, rename struct dev_power_domain to struct dev_pm_domain and rename the related pointers in struct device and struct pm_clk_notifier_block from pwr_domain to pm_domain.

The patch changes it to use implicit soc name for spi device type definition. In this way, we can easily align the naming scheme with device tree binding, which comes later. It removes fifosize from spi_imx_data and adds devtype there, so that fifosize can be set in an inline function according to devtype. Also, cpu_is_mx can be replaced by inline functions checking devtype.
