* [PATCH] NTP: ntp-helper functionsjohn stultz2005-09-07
| | | | | | | | | | | | | | | | This patch cleans up a commonly repeated set of changes to the NTP state variables by adding two helper inline functions: ntp_clear(): Clears the ntp state variables ntp_synced(): Returns 1 if the system is synced with a time server.

* [PATCH] Fix function/macro name collision on i386 oprofileDavid Gibson2005-09-07
| | | | | | | | | | | | | | | | The i386 OProfile code has a function named nmi_exit(), which collides with the nmi_exit() macro in linux/hardirq.h. At the moment, we get away with it, because hardirq.h isn't included in the oprofile code. I hit this as a bug when working with a patch which (indirectly) adds a #include of hardirq.h to oprofile. Regardless, the name collision is probably not a good idea, so this patch fixes it, renaming the oprofile function to op_nmi_exit(). It also renames the nmi_init() and nmi_timer_init() functions similarly, for consistency.

* [PATCH] compat: be more consistent about [ug]id_tStephen Rothwell2005-09-07
| | | | | | | | | | | | | | | | | | | | When I first wrote the compat layer patches, I was somewhat cavalier about the definition of compat_uid_t and compat_gid_t (or maybe I just misunderstood :-)). This patch makes the compat types much more consistent with the types we are being compatible with and hopefully will fix a few bugs along the way. compat type type in compat arch __compat_[ug]id_t __kernel_[ug]id_t __compat_[ug]id32_t __kernel_[ug]id32_t compat_[ug]id_t [ug]id_t The difference is that compat_uid_t is always 32 bits (for the archs we care about) but __compat_uid_t may be 16 bits on some.

* [PATCH] NMI: Update NMI users of RCU to use new APIPaul E. McKenney2005-09-07
| | | | | | | | | | | | | Uses of RCU for dynamically changeable NMI handlers need to use the new rcu_dereference() and rcu_assign_pointer() facilities. This change makes it clear that these uses are safe from a memory-barrier viewpoint, but the main purpose is to document exactly what operations are being protected by RCU. This has been tested on x86 and x86-64, which are the only architectures affected by this change.

* [PATCH] detect soft lockupsIngo Molnar2005-09-07
| | | | | | | | | | | | | | | | | | | This patch adds a new kernel debug feature: CONFIG_DETECT_SOFTLOCKUP. When enabled then per-CPU watchdog threads are started, which try to run once per second. If they get delayed for more than 10 seconds then a callback from the timer interrupt detects this condition and prints out a warning message and a stack dump (once per lockup incident). The feature is otherwise non-intrusive, it doesnt try to unlock the box in any way, it only gets the debug info out, automatically, and on all CPUs affected by the lockup.

* [PATCH] x86/x86_64: deferred handling of writes to /proc/irqxx/smp_affinityAshok Raj2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When handling writes to /proc/irq, current code is re-programming rte entries directly. This is not recommended and could potentially cause chipset's to lockup, or cause missing interrupts. CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the interrupt is pending. The same needs to be done for /proc/irq handling as well. Otherwise user space irq balancers are really not doing the right thing. - Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for lack of a generic name. - added move_irq out of IRQ_BALANCE, and added this same to X86_64 - Added new proc handler for write, so we can do deferred write at irq handling time. - Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead it now shows only active cpu masks, or exactly what was set. - Provided a common move_irq implementation, instead of duplicating when using generic irq framework. Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off. Tested UP builds as well. MSI testing: tbd: I have cards, need to look for a x-over cable, although I did test an earlier version of this patch. Will test in a couple days.

On POWER5, ERAT entries created in real mode have the class bit clear.
