Add the DTS file to describe the clearfog pro model - we update the platform name and compatible string compared to the original version. The original version remains for compatibility for the time being as the name of the file has become established, and the machine name and/or compatible may be used by userspace. Signed-off-by:

Russell King authored
There are two versions of the clearfog - a base and a pro model. The base model has an additional PHY on eth1, replacing the DSA switch on the pro model. MPP assignments are slightly different. The base model also omits the second PCIe, and footprint for a PIC microcontroller. In order to cater for these differences, move all the existing clearfog support to a dtsi file before starting to modify it, to make the following changes more clear. Signed-off-by:

Move the SDHCI pinctrl node to the microsom file - the microsom can have optional eMMC support which uses these same pinctrl settings, so it is sensible to have these here. Signed-off-by:

Russell King authored
The optional SPI flash is fitted to the microsom, not the clearfog board, so it should be specified in the microsom DTS include file. Signed-off-by:
-
Russell King authored
The SPI flash #size-cells is specified in the binding documentation to have value 1, but we were setting it to zero. This wasn't causing any problem as we do not list any partitions, but it's worth specifying correctly if we're going to specify it at all. Signed-off-by:

I am getting the following warning when I build kernel 4.9-git on my PowerBook G4 with a 32-bit PPC processor: AS arch/powerpc/kernel/misc_32.o arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef] This problem is evident after commit 989cea5c ("kbuild: prevent lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an error that has been in the code since 2005 when this source file was created. That was with commit 9994a338 ("powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S"). The offending line does not make a lot of sense. This error does not seem to cause any errors in the executable, thus I am not recommending that it be applied to any stable versions. Thanks to Nicholas Piggin for suggesting this solution.

The timer type simplifications caused a new gcc warning: drivers/base/power/domain.c: In function ‘genpd_runtime_suspend’: drivers/base/power/domain.c:562:14: warning: ‘time_start’ may be used uninitialized in this function [-Wmaybe-uninitialized] elapsed_ns = ktime_to_ns(ktime_sub(ktime_get(), time_start)); despite the actual use of "time_start" not having changed in any way. It appears that simply changing the type of ktime_t from a union to a plain scalar type made gcc check the use. The variable wasn't actually used uninitialized, but gcc apparently failed to notice that the conditional around the use was exactly the same as the conditional around the initialization of that variable. Add an unnecessary initialization just to shut up the compiler. Signed-off-by: -

Pull timer type cleanups from Thomas Gleixner: "This series does a tree wide cleanup of types related to timers/timekeeping. - Get rid of cycles_t and use a plain u64. The type is not really helpful and caused more confusion than clarity - Get rid of the ktime union. The union has become useless as we use the scalar nanoseconds storage unconditionally now. The 32bit timespec alike storage got removed due to the Y2038 limitations some time ago. That leaves the odd union access around for no reason. Clean it up. Both changes have been done with coccinelle and a small amount of manual mopping up" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: ktime: Get rid of ktime_equal() ktime: Cleanup ktime_set() usage ktime: Get rid of the union clocksource: Use a plain u64 instead of cycle_t -

Add a new page flag, PageWaiters, to indicate the page waitqueue has tasks waiting. This can be tested rather than testing waitqueue_active which requires another cacheline load. This bit is always set when the page has tasks on page_waitqueue(page), and is set and cleared under the waitqueue lock. It may be set when there are no tasks on the waitqueue, which will cause a harmless extra wakeup check that will clears the bit. The generic bit-waitqueue infrastructure is no longer used for pages. Instead, waitqueues are used directly with a custom key type. The generic code was not flexible enough to have PageWaiters manipulation under the waitqueue lock (which simplifies concurrency). This improves the performance of page lock intensive microbenchmarks by 2-3%. Putting two bits in the same word opens the opportunity to remove the memory barrier between clearing the lock bit and testing the waiters bit, after some work on the arch primitives (e.g., ensuring memory operand widths match and cover both bits).

ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment. Signed-off-by: -
Thomas Gleixner authored
ktime is a union because the initial implementation stored the time in scalar nanoseconds on 64 bit machine and in a endianess optimized timespec variant for 32bit machines. The Y2038 cleanup removed the timespec variant and switched everything to scalar nanoseconds. The union remained, but become completely pointless. Get rid of the union and just keep ktime_t as simple typedef of type s64. The conversion was done with coccinelle and some manual mopping up. Signed-off-by: -

There is no point in having an extra type for extra confusion. u64 is unambiguous. Conversion was done with the following coccinelle script: @rem@ @@ -typedef u64 cycle_t; @fix@ typedef cycle_t; @@ -cycle_t +u64 Signed-off-by: -

The mpic is either the main interrupt controller or is cascaded behind a GIC. The mpic is single instance and the modes are mutually exclusive, so there is no reason to have seperate cpu hotplug states. Signed-off-by:

Even if both drivers are compiled in only one instance can run on a given system depending on the available GIC version. So having seperate hotplug states for them is pointless. Signed-off-by:

When the state names got added a script was used to add the extra argument to the calls. The script basically converted the state constant to a string, but the cleanup to convert these strings into meaningful ones did not happen. Replace all the useless strings with 'subsys/xxx/yyy:state' strings which are used in all the other places already. Signed-off-by:

hotcpu_notifier(), cpu_notifier(), __hotcpu_notifier(), __cpu_notifier(), register_hotcpu_notifier(), register_cpu_notifier(), __register_hotcpu_notifier(), __register_cpu_notifier(), unregister_hotcpu_notifier(), unregister_cpu_notifier(), __unregister_hotcpu_notifier(), __unregister_cpu_notifier() are unused now. Remove them and all related code. Remove also the now pointless cpu notifier error injection mechanism. The states can be executed step by step and error rollback is the same as cpu down, so any state transition can be tested w/o requiring the notifier error injection. Some CPU hotplug states are kept as they are (ab)used for hotplug state tracking. Signed-off-by:
