Luck, Tony authored
In commit d1669912 idle: Implement generic idle function Thomas Gleixner cleaned up many things but perturbed some fragile code that was keeping ia64 alive. So we started seeing: WARNING: at kernel/cpu/idle.c:94 cpu_idle_loop+0x360/0x380() and other unpleasantness like system hangs during boot. We really shouldn't ever halt with interrupts disabled.

Add generic cpu_idle support sparc32: - replace call to cpu_idle() with cpu_startup_entry() - add arch_cpu_idle() sparc64: - smp_callin() now include cpu_startup_entry() call so we can skip calling cpu_idle from assembler - add arch_cpu_idle() and arch_cpu_idle_dead() Signed-off-by:

The Kconfig symbol ARCH_HAS_DEFAULT_IDLE is unused. Commit a0bfa137 ("cpuidle: stop depending on pm_idle") removed the only place were it was actually used. But it did not remove its Kconfig entries (for sh and x86). Remove those two entries now. Signed-off-by:

The microblaze idle loop provides a polling and a non polling version, which are suprisingly both polling, just with slightly different instrumentation. Remove them and use the generic poller. Signed-off-by:

The generic idle loop implements all functionality. Aside of that it allows arc to implement the tsk_is_polling() functionality correctly, despite the patently (now gone) comment in the original arc cpu_idle() function: /* Since we SLEEP in idle loop, TIF_POLLING_NRFLAG can't be set */ See kernel/cpu/idle.c Signed-off-by:

All idle functions in arch/* are more or less the same, plus minus a few bugs and extra instrumentation, tickless support and other optional items. Implement a generic idle function which resembles the functionality found in arch/. Provide weak arch_cpu_idle_* functions which can be overridden by the architecture code if needed. Signed-off-by:
