* ARM: gic: consolidate PPI handlingMarc Zyngier2011-10-231-7/+0
| | | | | | | | | | | | | | | | | | | | | | | PPI handling is a bit of an odd beast. It uses its own low level handling code and is hardwired to the local timers (hence lacking a registration interface). Instead, switch the low handling to the normal SPI handling code. PPIs are handled by the handle_percpu_devid_irq flow. This also allows the removal of some duplicated code.

* ARM: entry: re-allocate registers in irq entry assembly macrosRussell King2011-07-021-7/+7
| | | | | | | This avoids the irq entry assembly corrupting r5, thereby allowing it to be preserved through to the svc exit code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: 6959/1: SMP build fix for entry-macro-multi.SMagnus Damm2011-06-171-0/+2
| | | | | | | | | | | | | | | | | The assembly code in entry-macro-multi.S does not build without the include asm/assembler.h in the case of CONFIG_SMP=y. Fixes the rather theoretical SMP build of mach-shmobile/entry-intc.c: arch/arm/include/asm/entry-macro-multi.S: Assembler messages: arch/arm/include/asm/entry-macro-multi.S:20: Error: bad instruction `alt_smp(test_for_ipi r0,r6,r5,lr)' arch/arm/include/asm/entry-macro-multi.S:20: Error: bad instruction `alt_up_b(9997f)' make[1]: *** [arch/arm/mach-shmobile/entry-intc.o] Error 1 make: *** [arch/arm/mach-shmobile] Error 2 make: *** Waiting for unfinished jobs....

* ARM: 6538/1: Subarch IRQ handler macros V3Magnus Damm2010-12-241-0/+44
Per subarch interrupt handler macros V3. This patch breaks out code from the irq_handler macro into arch_irq_handler and arch_irq_handler_default. The macros are put in the header file "entry-macro-multi.S" The arch_irq_handler_default macro is designed to be used by irq_handler in entry-armv.S while arch_irq_handler is suitable for per-subarch use.
