Pull irq fixes from Thomas Gleixner: "This contains: - a series of fixes for interrupt drivers to prevent a potential race when installing a chained interrupt handler - a fix for cpumask pointer misuse - a fix for using the wrong interrupt number from struct irq_data - removal of unused code and outdated comments - a few new helper functions which allow us to cleanup the interrupt handling code further in 4.3 I decided against doing the cleanup at the end of this merge window and rather do the preparatory steps for 4.3, so we can run the final ABI change at the end of the 4.3 merge window with less risk" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (26 commits) ARM/LPC32xx: Use irq not hwirq for __irq_set_handler_locked() genirq: Implement irq_set_handler_locked()/irq_set_chip_handler_name_locked() genirq: Introduce helper irq_desc_get_irq() genirq: Remove irq_node() genirq: Clean up outdated comments related to include/linux/irqdesc.h mn10300: Fix incorrect use of irq_data->affinity MIPS/ralink: Fix race in installing chained IRQ handler MIPS/pci: Fix race in installing chained IRQ handler MIPS/ath25: Fix race in installing chained IRQ handler MIPS/ath25: Fix race in installing chained IRQ handler m68k/psc: Fix race in installing chained IRQ handler avr32/at32ap: Fix race in installing chained IRQ handler sh/intc: Fix race in installing chained IRQ handler sh/intc: Fix potential race in installing chained IRQ handler pinctrl/sun4i: Fix race in installing chained IRQ handler pinctrl/samsung: Fix race in installing chained IRQ handler pinctrl/samsung: Fix race in installing chained IRQ handler pinctrl/exynos: Fix race in installing chained IRQ handler pinctrl/st: Fix race in installing chained IRQ handler pinctrl/adi2: Fix race in installing chained IRQ handler ...

sh/intc: Fix race in installing chained IRQ handler

2015-06-25T09:57:50Z

Fix a race where a pending interrupt could be received and the handler called before the handler's data has been setup, by converting to irq_set_chained_handler_and_data(). Search and conversion was done with coccinelle: @@ expression E1, E2, E3; @@ ( -if (irq_set_chained_handler(E1, E3) != 0) - BUG(); | -irq_set_chained_handler(E1, E3); ) -irq_set_handler_data(E1, E2); +irq_set_chained_handler_and_data(E1, E3, E2); @@ expression E1, E2, E3; @@ ( -if (irq_set_chained_handler(E1, E3) != 0) - BUG(); ... | -irq_set_chained_handler(E1, E3); ... ) -irq_set_handler_data(E1, E2); +irq_set_chained_handler_and_data(E1, E3, E2); Reported-by: Russell King Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Simon Horman Cc: Magnus Damm Cc: linux-sh@vger.kernel.org

sh/intc: Fix potential race in installing chained IRQ handler

2015-06-25T09:57:19Z

Fix a race where a pending interrupt could be received and the handler called before the handler's data has been setup, by moving the call to irq_set_chained_handler() after the function which sets up the handler data.

drivers: sh: remove boilerplate code and use USE_PM_CLK_RUNTIME_OPS

2015-05-12T21:55:38Z

USE_PM_CLK_RUNTIME_OPS is introduced so we don't repeat the same code to do runtime_suspend and runtime_resume across users of PM clocks. Use it to remove the boilerplate code.

drivers: sh: Disable PM runtime for multi-platform r8a73a4 with genpd

2015-04-27T04:08:13Z

If the default PM domain using PM_CLK is used for PM runtime, the real PM domain(s) cannot be registered from DT later. Hence do not enable it when running a multi-platform kernel with genpd support on an r8a73a4. The R-Mobile PM domain driver will take care of PM runtime management of the module clocks. The default PM domain is still needed for: - platforms without genpd support, - the legacy (non-DT) case, where genpd may take over later, except for the C5 "always on" PM domain.

drivers: sh / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM

2014-12-05T02:08:24Z

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM in drivers/sh/pm_runtime.c. Signed-off-by: Rafael J. Wysocki Acked-by: Simon Horman Acked-by: Geert Uytterhoeven
