2007-02-17[POWERPC] 83xx: Updated and renamed MPC8360PB to MPC836x MDSKumar Gala
The MPC836x PB board is really just one part of the MPC836x MDS. We currently name all other PB boards as MDS. Removed all references to PB and replaced with MDS. Additionally renamed the .dts to match the defconfig (mpc836x_mds*). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-02-17[POWERPC] 83xx: Use of_platform_bus_probe to setup QE devicesKumar Gala
Use of_platform_bus_probe to setup devices on the of_platform_bus since its much cleaner. We explicitly specify the bus ids since the we want to get rid of the default mechanism in the future. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-02-17[POWERPC] 83xx: use default value of loops_per_jiffyKumar Gala
Use the default value setup by initialization of loops_per_jiffy, its close enough for 83xx and will get fixed up by calibrate_delay(). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-02-17[POWERPC] 83xx: Cleaning up machine probing and board initcallsKumar Gala
Cleaned up the probing functionality to be more consistent across all 83xx boards and added machine_is() protection around board initcalls to ensure they only do something if we are actually running on that board. Additionally, removed some dead code on mpc832x_mds. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-02-17[ARM] 4220/1: S3C24XX: DMA system initialised from sysdevBen Dooks
This patch gets the DMA system for the S3C24XX ready for the S3C2443, which requires 6 dma channels at a different stride, and different base IRQ. The DMA system is now initialised from the same drivers which apply the DMA mappings, as well as removing the DMA sysdev intialisation out of the main init code (which is now being called from a sysdev probe, so cannot add a new sysdev) Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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.)

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.

Update the timer IRQ to call into the PIT/HPET driver's event handler and the lapic-timer IRQ to call into the lapic clockevent driver. The assignement of timer functionality is delegated to the core framework code and replaces the compile and runtime evalution in do_timer_interrupt_hook() Use the clockevents broadcast support and implement the lapic_broadcast function for ACPI.

2007-02-16[PATCH] Mark TSC on GeodeLX reliableMarcelo Tosatti
The Geode can safely use the TSC for highres, since: 1) Does not support frequency scaling, 2) The TSC _does_ count when the CPU is halted. Furthermore, the Geode supports a mode called "suspension on halt", where Suspend mode (which interacts with the power management states) is entered. TSC counting during suspend mode is controlled by bit 8 of the Bus Controller Configuration Register #0 (thanks Tom!). 3) no SMP :) Check if "RTSC counts during suspension" and remove the requirement for verification, so the clocksource code can safely select it as an timesource for the highres timers subsystem.

make the TSC synchronization code more robust, and unify it between x86_64 and i386. The biggest change is the removal of the 'fix up TSCs' code on x86_64 and i386, in some rare cases it was /causing/ time-warps on SMP systems. The new code only checks for TSC asynchronity - and if it can prove a time-warp (if it can observe the TSC going backwards when going from one CPU to another within a critical section), then the TSC clock-source is turned off. The TSC synchronization-checking code also got moved into a separate file.

2007-02-16[PATCH] Simplify the registration of clocksourcesThomas Gleixner
Enqueue clocksources in rating order to make selection of the clocksource easier. Also check the match with an user override at enqueue time. Preparatory patch for the generic clocksource verification.

2007-02-16[PATCH] i386 Remove useless code in tsc.cThomas Gleixner
The delayed work code in arch/i386/kernel/tsc.c is an unused leftover of the GTOD conversion. Remove it.

2007-02-16[PATCH] Add irq flag to disable balancing for an interruptThomas Gleixner
Add a flag so we can prevent the irq balancing of an interrupt. Move the bits, so we have room for more :) Necessary for the ability to setup clocksources more flexible (e.g. use the different HPET channels per CPU) Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Cc: john stultz <johnstul@us.ibm.com> Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
