Pull MIPS updates from Ralf Baechle: "This is the main pull request for 4.3 for MIPS. Here's the summary: Three fixes that didn't make 4.2-stable: - a -Os build might compile the kernel using the MIPS16 instruction set but the R2 optimized inline functions in <uapi/asm/swab.h> are implemented using 32-bit wide instructions which is invalid. - a build error in pgtable-bits.h for a particular kernel configuration. - accessing registers of the CM GCR might have been compiled to use 64 bit accesses but these registers are onl 32 bit wide. And also a few new bits: - move the ATH79 GPIO driver to drivers/gpio - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h, change ATH79 accordingly. - fix definition of pgprot_writecombine - add an implementation of dma_map_ops.mmap - fix alignment of quiet build output for vmlinuz link - BCM47xx: Use kmemdup rather than duplicating its implementation - Netlogic: Fix 0x0x prefixes of constants. - merge Bjorn Helgaas' series to remove most of the weak keywords from function declarations. - CP0 and CP1 registers are best considered treated as unsigned values to avoid large values from becoming negative values. - improve support for the MIPS GIC timer. - enable common clock framework for Malta and SEAD3. - a number of improvments and fixes to dump_tlb(). - document the MIPS TLB dump functionality in Magic SysRq. - Cavium Octeon CN68XX improvments. - NetLogic improvments. - irq: Use access helper irq_data_get_affinity_mask. - handle MSA unaligned accesses. - a number of R6-related math-emu fixes. - support for I6400. - improvments to MSA support. - add uprobes support. - move from deprecated __initcall to arch_initcall. - remove finish_arch_switch(). - IRQ cleanups by Thomas Gleixner. - migrate to new 'set-state' interface. - random small cleanups" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (148 commits) MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16.

2015-09-03CLOCKSOURCE: Add Pistachio clocksource-only driverEzequiel Garcia
The Pistachio SoC provides four general purpose timers, and allow to implement a clocksource driver. This driver can be used as a replacement for the MIPS GIC and MIPS R4K clocksources and sched clocks, which are clocked from the CPU clock. Given the general purpose timers are clocked from an independent clock, this new clocksource driver will be useful to introduce CPUFreq support for Pistachio machines.

For the clock to be used (e.g. get its rate through clk_get_rate) it should be prepared and enabled first.

2015-08-10clockevents/drivers/timer-sp804: Migrate to new 'set-state' interfaceViresh Kumar
Migrate timer-sp driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. There are few more changes worth noticing: - The clockevent device was disabled by writing: 'TIMER_CTRL_32BIT | TIMER_CTRL_IE' to ctrl register earlier. i.e. by un-setting the TIMER_CTRL_ENABLE bit. Its done by writing zero now and should have the same effect. - For shutdown and resume we were writing the same value twice to the register (to disable the timer), which is fixed now. - Switching to oneshot mode was divided into two parts earlier: - Firstly set_mode() was writing: 'TIMER_CTRL_32BIT | TIMER_CTRL_IE | TIMER_CTRL_ONESHOT' to ctrl register (device not enabled yet) - Then sp804_set_next_event() was enabling the device by writing 'readl(ctrl) | TIMER_CTRL_ENABLE' to the ctrl register. This was unnecessarily complicated. - Change this to: Stop device on set_state_oneshot and configure it in sp804_set_next_event().

Migrate timer-imx-gpt driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. Also drop: - 'imx_timer.cem': It was caching the last state of the clockevent device. The same behavior can be achieved by using clockevents state helpers. These helpers are only required for oneshot mode as shutdown/resume wouldn't be done twice by the core. - 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore by drivers. The prints are modified to print the set-state functions name now to debug the driver.

Commit d2348fb6fdc6 ("tick: Dynamically set broadcast irq affinity") adds one excellent feature CLOCK_EVT_FEAT_DYNIRQ to let the core set the interrupt affinity of the broadcast interrupt to the cpu which has the earliest expiry time.
