2007-02-17[PARISC] Fix show_stack() when we can't kmallocMatthew Wilcox
show_stack() was calling kzalloc() to allocate a struct pt_regs. This meant that *really* early stack dumps would cause a null pointer dereference. x86_64 allocates its pt_regs on the stack, so do the same. Kyle actually committed this exact patch to CVS on Wed Jul 26 14:32:39 2006 UTC, and never moved it across to git. Bad Kyle.

2007-02-17[POWERPC] pseries: Enabling auto poweron after power is restored.Manish Ahuja
During power outages, the UPS notifies the system for a shutdown. In the current setup, it isn't possible to poweron when power is restored. This patch fixes the issue by calling the right ibm,power-off-ups token during such events. It also adds a sysfs interface so userspace can specify whether or not to power on when power is restored.

2007-02-16[PATCH] genirq: do not mask interrupts by defaultIngo Molnar
Never mask interrupts immediately upon request. Disabling interrupts in high-performance codepaths is rare, and on the other hand this change could recover lost edges (or even other types of lost interrupts) by conservatively only masking interrupts after they happen. (NOTE: with this change the highlevel irq-disable code still soft-disables this IRQ line - and if such an interrupt happens then the IRQ flow handler keeps the IRQ masked.) Mark i8529A controllers as 'never loses an edge'.

2007-02-16[PATCH] i386 prepare nmi watchdog for dynticksThomas Gleixner
The NMI watchdog implementation assumes that the local APIC timer interrupt is happening. This assumption is not longer true when high resolution timers and dynamic ticks come into play, as they may switch off the local APIC timer completely. Take the PIT/HPET interrupts into account too, to avoid false positives.

2007-02-16[PATCH] i386 rework local apic timer calibrationThomas Gleixner
The local apic timer calibration has two problem cases: 1. The calibration is based on readout of the PIT/HPET timer to detect the wrap of the periodic tick. It happens that a box gets stuck in the calibration loop due to a PIT with a broken readout function. 2. CoreDuo boxen show a sporadic PIT runs too slow defect, which results in a wrong lapic calibration. The PIT goes back to normal operation once the lapic timer is switched to periodic mode. Both are existing and unfixed problems in the current upstream kernel and prevent certain laptops and other systems from booting Linux. Rework the code to address both problems: - Make the calibration interrupt driven. This removes the wait_timer_tick magic hackery from lapic.c and time_hpet.c. The clockevents framework allows easy substitution of the global tick event handler for the calibration. This is more accurate than monitoring jiffies. At this point of the boot process, nothing disturbes the interrupt delivery, so the results are very accurate. - Verify the calibration against the PM timer, when available by using the early access function. When the measured calibration period is outside of an one percent window, then the lapic timer calibration is adjusted to the pm timer result. - Verify the calibration by running the lapic timer with the calibration handler. Disable lapic timer in case of deviation. This also removes the "synchronization" of the local apic timer to the global tick. This synchronization never worked, as there is no way to synchronize PIT(HPET) and local APIC timer. The synchronization by waiting for the tick just alignes the local APIC timer for the first events, but later the events drift away due to the different clocks. Removing the "sync" is just randomizing the asynchronous behaviour at setup time.
