| * | futex: Sanitize futex ops argument typesMichel Lespinasse2011-03-111-6/+7

| * | futex: Sanitize cmpxchg_futex_value_locked APIMichel Lespinasse2011-03-111-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cmpxchg_futex_value_locked API was funny in that it returned either the original, user-exposed futex value OR an error code such as -EFAULT. This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

* alpha: fix breakage caused by df9ee29270Ivan Kokshaysky2011-01-171-3/+5
| | | | | | | | | | | | | | Commit df9ee29270 made arch_local_irq_save and arch_local_irq_restore static inline which with -Werror trips up on __set_hae() and _set_hae() which are extern inline. The naive solution is to make __set_hae() and set_hae() static inline but for reasons described in commit d559d4a24a3fe this breaks the generic kernel build. Instead, since this is architecture specific code, this patch hard wires in the architecture specific method f disabling and enabling interrupts.

|/ | | | | | | | | | | | | | | | | | | | | | The perf hardware pmu got initialized at various points in the boot, some before early_initcall() some after (notably arch_initcall). The problem is that the NMI lockup detector is ran from early_initcall() and expects the hardware pmu to be present. Sanitize this by moving all architecture hardware pmu implementations to initialize at early_initcall() and move the lockup detector to an explicit initcall right after that.

* | | alpha: use single HAE window on T2 core logic (gamma, sable)Ivan Kokshaysky2010-10-264-40/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | T2 are the only alpha SMP systems that do HAE switching at runtime, which is fundamentally racy on SMP. This patch limits MMIO space on T2 to HAE0 only, like we did on MCPCIA (rawhide) long ago. This leaves us with only 112 Mb of PCI MMIO (128 Mb HAE aperture minus 16 Mb reserved for EISA), but since linux PCI allocations are reasonably tight, it should be enough for sane hardware configurations. Also, fix a typo in MCPCIA_FROB_MMIO macro which shouldn't call set_hae() if MCPCIA_ONE_HAE_WINDOW is defined. It's more for correctness, as set_hae() is a no-op anyway in that case.

In linux/irqflags.h under one configuration, it maps: local_irq_enable() -> raw_local_irq_enable() local_irq_disable() -> raw_local_irq_disable() local_irq_save() -> raw_local_irq_save() ... and under the other configuration, it maps: raw_local_irq_enable() -> local_irq_enable() raw_local_irq_disable() -> local_irq_disable() raw_local_irq_save() -> local_irq_save() ... This is quite confusing. There should be one set of names expected of the arch, and this should be wrapped to give another set of names that are expected by users of this facility. Change this to have the arch provide: flags = arch_local_save_flags() flags = arch_local_irq_save() arch_local_irq_restore(flags) arch_local_irq_disable() arch_local_irq_enable() arch_irqs_disabled_flags(flags) arch_irqs_disabled() arch_safe_halt() Then linux/irqflags.h wraps these to provide: raw_local_save_flags(flags) raw_local_irq_save(flags) raw_local_irq_restore(flags) raw_local_irq_disable() raw_local_irq_enable() raw_irqs_disabled_flags(flags) raw_irqs_disabled() raw_safe_halt() with type checking on the flags 'arguments', and then wraps those to provide: local_save_flags(flags) local_irq_save(flags) local_irq_restore(flags) local_irq_disable() local_irq_enable() irqs_disabled_flags(flags) irqs_disabled() safe_halt() with tracing included if enabled. The arch functions can now all be inline functions rather than some of them having to be macros.
