git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "Yet another big pile of changes: - More year 2038 work from Arnd slowly reaching the point where we need to think about the syscalls themself. - A new timer function which allows to conditionally (re)arm a timer only when it's either not running or the new expiry time is sooner than the armed expiry time. This allows to use a single timer for multiple timeout requirements w/o caring about the first expiry time at the call site. - A new NMI safe accessor to clock real time for the printk timestamp work. Can be used by tracing, perf as well if required. - A large number of timer setup conversions from Kees which got collected here because either maintainers requested so or they simply got ignored. As Kees pointed out already there are a few trivial merge conflicts and some redundant commits which was unavoidable due to the size of this conversion effort. - Avoid a redundant iteration in the timer wheel softirq processing. - Provide a mechanism to treat RTC implementations depending on their hardware properties, i.e. don't inflict the write at the 0.5 seconds boundary which originates from the PC CMOS RTC to all RTCs. No functional change as drivers need to be updated separately. - The usual small updates to core code clocksource drivers. Nothing really exciting" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (111 commits) timers: Add a function to start/reduce a timer pstore: Use ktime_get_real_fast_ns() instead of __getnstimeofday() timer: Prepare to change all DEFINE_TIMER() callbacks netfilter: ipvs: Convert timers to use timer_setup() scsi: qla2xxx: Convert timers to use timer_setup() block/aoe: discover_timer: Convert timers to use timer_setup() ide: Convert timers to use timer_setup() drbd: Convert timers to use timer_setup() mailbox: Convert timers to use timer_setup() crypto: Convert timers to use timer_setup() drivers/pcmcia: omap1: Fix error in automated timer conversion ARM: footbridge: Fix typo in timer conversion drivers/sgi-xp: Convert timers to use timer_setup() drivers/pcmcia: Convert timers to use timer_setup() drivers/memstick: Convert timers to use timer_setup() drivers/macintosh: Convert timers to use timer_setup() hwrng/xgene-rng: Convert timers to use timer_setup() auxdisplay: Convert timers to use timer_setup() sparc/led: Convert timers to use timer_setup() mips: ip22/32: Convert timers to use timer_setup() ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq core updates from Thomas Gleixner: "A rather large update for the interrupt core code and the irq chip drivers: - Add a new bitmap matrix allocator and supporting changes, which is used to replace the x86 vector allocator which comes with separate pull request. This allows to replace the convoluted nested loop allocation function in x86 with a facility which supports the recently added property of managed interrupts proper and allows to switch to a best effort vector reservation scheme, which addresses problems with vector exhaustion. - A large update to the ARM GIC-V3-ITS driver adding support for range selectors. - New interrupt controllers: - Meson and Meson8 GPIO - BCM7271 L2 - Socionext EXIU If you expected that this will stop at some point, I have to disappoint you. There are new ones posted already. Sigh! - STM32 interrupt controller support for new platforms. - A pile of fixes, cleanups and updates to the MIPS GIC driver - The usual small fixes, cleanups and updates all over the place.

Pull OpenRISC updates from Stafford Horne: "The OpenRISC work is a bit more interesting this time, adding SMP support and a few general cleanups. Small Things: - Move OpenRISC docs into Documentation and clean them up - Document previously undocumented devicetree bindings - Update the or1ksim dts to use stdout-path OpenRISC SMP support details: - First the "use shadow registers" and "define CPU_BIG_ENDIAN as true" get the architecture ready for SMP. - The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and qrwlocks" add the SMP locking infrastructure as needed. Using the qspinlocks and qrwlocks as suggested by Peter Z while reviewing the original spinlocks implementation. - The "support for ompic" adds a new irqchip device which is used for IPI communication to support SMP. - The "initial SMP support" adds smp.c and makes changes to all of the necessary data-structures to be per-cpu. The remaining patches are bug fixes and debug helpers which I wanted to keep separate from the "initial SMP support" in order to allow them to be reviewed on their own. This includes: - add cacheflush support to fix icache aliasing - fix initial preempt state for secondary cpu tasks - sleep instead of spin on secondary wait - support framepointers and STACKTRACE_SUPPORT - enable LOCKDEP_SUPPORT and irqflags tracing - timer sync: Add tick timer sync logic - fix possible deadlock in timer sync, pointed out by mips guys Note: the irqchip patch was reviewed with Marc and we agreed to push it together with these patches" * tag 'for-linus' of git://github.com/openrisc/linux: openrisc: fix possible deadlock scenario during timer sync openrisc: pass endianness info to sparse openrisc: add tick timer multi-core sync logic openrisc: enable LOCKDEP_SUPPORT and irqflags tracing openrisc: support framepointers and STACKTRACE_SUPPORT openrisc: add simple_smp dts and defconfig for simulators openrisc: add cacheflush support to fix icache aliasing openrisc: sleep instead of spin on secondary wait openrisc: fix initial preempt state for secondary cpu tasks openrisc: initial SMP support irqchip: add initial support for ompic dt-bindings: add openrisc to vendor prefixes list openrisc: use qspinlocks and qrwlocks openrisc: add 1 and 2 byte cmpxchg support openrisc: use shadow registers to save regs on exception dt-bindings: openrisc: Add OpenRISC platform SoC Documentation: openrisc: Updates to README Documentation: Move OpenRISC docs out of arch/ MAINTAINERS: Add OpenRISC pic maintainer openrisc: dts: or1ksim: Add stdout-path

If the array is not present, assume all chip selects are native. This is the standard behavior for SPI masters configured via the device tree and the behavior of this driver as well when it is configured via device tree. This reduces platform data vs DT differences and allows most of the platform data based boards to remove their chip select arrays.

Note that spi_bitbang_start() has to be called before requesting GPIOs because the GPIO data in the spi master is populated when the master is registed, and that doesn't happen until spi_bitbang_start() is called.

2017-11-10spi: imx: GPIO based chip selects should not be requiredTrent Piepho1-8/+10
The driver will fail to load if no gpio chip selects are specified, this patch changes this so that it no longer fails. It's possible to use all native chip selects, in which case there is no reason to have a gpio chip select array. This is what happens if the *optional* device tree property "cs-gpios" is omitted. The spi core already checks for the absence of gpio chip selects in the master and assigns any slaves the gpio_cs value of -ENOENT. Also have the driver respect the standard SPI device tree property "num-cs" to allow setting the number of chip selects without using cs-gpios.

After the panic teardown firmware command, health_care detects the error in PCI bus and calls the mlx5_pci_err_detected.

2017-11-09m68k/mac: Disentangle VIA/RBV and NuBus initializationFinn Thain1-13/+0
The Nubus subsystem should not be concerned with differences between VIA, RBV and OSS platforms. It should be portable across Macs and PowerMacs. This goal has implications for the initialization code relating to bus locking and slot interrupts. During Nubus initialization, bus transactions are "unlocked": on VIA2 and RBV machines, via_nubus_init() sets a bit in the via2[gBufB] register to allow bus-mastering Nubus cards to arbitrate for the bus. This happens upon subsys_initcall(nubus_init). But because nubus_init() has no effect on card state, this sequence is arbitrary. Moreover, when Penguin is used to boot Linux, the bus is already unlocked when Linux starts. On OSS machines there's no attempt to unlock Nubus transactions at all. (Maybe there's no benefit on that platform or maybe no-one knows how.) All of this demonstrates that there's no benefit in locking out bus-mastering cards, as yet. (If the need arises, we could lock the bus for the duration of a timing-critical operation.) NetBSD unlocks the Nubus early (at VIA initialization) and we can do the same. via_nubus_init() is also responsible for some VIA interrupt setup that should happen earlier than subsys_initcall(nubus_init). And actually, the Nubus subsystem need not be involved with slot interrupts: SLOT2IRQ works fine because Nubus slot IRQs are geographically assigned (regardless of platform). For certain platforms with PDS slots, some Nubus IRQs may be platform IRQs and this is not something that the NuBus subsystem should worry about. So let's invoke via_nubus_init() earlier and make the platform responsible for bus unlocking and interrupt setup instead of the NuBus subsystem.

The ap_qact_ap_info struct can get more easy handled when the fields in there can be accessed by their names but also the struct as a whole with just an unsigned long value. This patch reworks this struct to be a union and adapt the using code accordingly.
