2017-01-02ARM: davinci: da8xx: Fix sleeping function called from invalid contextAlexandre Bailon
Everytime the usb20 phy is enabled, there is a "sleeping function called from invalid context" BUG. In addition, there is a recursive locking happening because of the recurse call to clk_enable(). clk_enable() from arch/arm/mach-davinci/clock.c uses spin_lock_irqsave() before to invoke the callback usb20_phy_clk_enable(). usb20_phy_clk_enable() uses clk_get() and clk_enable_prepapre() which may sleep. Replace clk_prepare_enable() by davinci_clk_enable().

2017-01-02ARM: davinci: Make __clk_{enable,disable} functions publicAlexandre Bailon
In some cases, there is a need to enable a clock as part of clock enable callback of a different clock. For example, USB 2.0 PHY clock enable requires USB 2.0 clock to be enabled. In this case, it is safe to instead call __clk_enable() since the clock framework lock is already taken. Calling clk_enable() causes recursive locking error. A similar case arises in the clock disable path. To enable such usage, make __clk_{enable,disable} functions publicly available outside of clock.c. Also, call them davinci_clk_{enable|disable} now to be consistent with how other davinci-specific clock functions are named. Note that these functions are not exported to drivers. They are meant for usage in platform specific clock management code.

2016-12-29parisc: Mark cr16 clocksource unstable on SMP systemsHelge Deller
The cr16 interval timer of each CPU is not syncronized to other cr16 timers in other CPUs in a SMP system. So, delay the registration of the cr16 clocksource until all CPUs have been detected and then - if we are on a SMP machine - mark the cr16 clocksource as unstable and lower it's rating before registering it at the clocksource framework. This patch fixes the stalled CPU warnings which we have seen since introduction of the cr16 clocksource. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org> # v4.8+
2016-12-29mm: optimize PageWaiters bit use for unlock_page()Linus Torvalds
In commit 62906027091f ("mm: add PageWaiters indicating tasks are waiting for a page bit") Nick Piggin made our page locking no longer unconditionally touch the hashed page waitqueue, which not only helps performance in general, but is particularly helpful on NUMA machines where the hashed wait queues can bounce around a lot. However, the "clear lock bit atomically and then test the waiters bit" sequence turns out to be much more expensive than it needs to be, because you get a nasty stall when trying to access the same word that just got updated atomically. On architectures where locking is done with LL/SC, this would be trivial to fix with a new primitive that clears one bit and tests another atomically, but that ends up not working on x86, where the only atomic operations that return the result end up being cmpxchg and xadd. The atomic bit operations return the old value of the same bit we changed, not the value of an unrelated bit. On x86, we could put the lock bit in the high bit of the byte, and use "xadd" with that bit (where the overflow ends up not touching other bits), and look at the other bits of the result. However, an even simpler model is to just use a regular atomic "and" to clear the lock bit, and then the sign bit in eflags will indicate the resulting state of the unrelated bit #7. So by moving the PageWaiters bit up to bit #7, we can atomically clear the lock bit and test the waiters bit on x86 too. And architectures with LL/SC (which is all the usual RISC suspects), the particular bit doesn't matter, so they are fine with this approach too. This avoids the extra access to the same atomic word, and thus avoids the costly stall at page unlock time. The only downside is that the interface ends up being a bit odd and specialized: clear a bit in a byte, and test the sign bit. Nick doesn't love the resulting name of the new primitive, but I'd rather make the name be descriptive and very clear about the limitation imposed by trying to work across all relevant architectures than make it be some generic thing that doesn't make the odd semantics explicit. So this introduces the new architecture primitive clear_bit_unlock_is_negative_byte(); and adds the trivial implementation for x86. We have a generic non-optimized fallback (that just does a "clear_bit()"+"test_bit(7)" combination) which can be overridden by any architecture that can do better. According to Nick, Power has the same hickup x86 has, for example, but some other architectures may not even care. All these optimizations mean that my page locking stress-test (which is just executing a lot of small short-lived shell scripts: "make test" in the git source tree) no longer makes our page locking look horribly bad. Before all these optimizations, just the unlock_page() costs were just over 3% of all CPU overhead on "make test". After this, it's down to 0.66%, so just a quarter of the cost it used to be. (The difference on NUMA is bigger, but there this micro-optimization is likely less noticeable, since the big issue on NUMA was not the accesses to 'struct page', but the waitqueue accesses that were already removed by Nick's earlier commit).

Fix a small typo after cleanup state names in cpu/hotplug. The new convention is 'subsys/xxx/yyy:state' where "state" here is called "starting" not "STARTING".

2016-12-25powerpc: Fix build warning on 32-bit PPCLarry Finger
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 989cea5c14be ("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 9994a33865f4 ("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.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 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
