2007-10-12x86: HPET force enable o ICH7 and laterVenki Pallipadi
Force detect and/or enable HPET on ICH chipsets. This patch just handles the detection part and following patches use this information. Adds a function to repeat the force enabling during resume time. Using HPET this way, instead of PIT increases the time CPUs can reside in C-state when system is totally idle. On my test system with Core 2 Duo, average C-state residency goes up from ~20mS to ~80mS.

2007-10-12x86: disable apic timer for AMD C1E enabled CPUsThomas Gleixner
AMDs C1E enabled CPUs stop the local apic timer, when both cores are idle. This is a hardware feature which breaks highres/dynticks. Add the same quirk as we have for 32 bit already.

2007-10-12x86: Fix irq0 / local apic timer accountingThomas Gleixner
The clock events merge introduced a change to the nmi watchdog code to handle the not longer increasing local apic timer count in the broadcast mode. This is fine for UP, but on SMP it pampers over a stuck CPU which is not handling the broadcast interrupt due to the unconditional sum up of local apic timer count and irq0 count. To cover all cases we need to keep track on which CPU irq0 is handled. In theory this is CPU#0 due to the explicit disabling of irq balancing for irq0, but there are systems which ignore this on the hardware level. The per cpu irq0 accounting allows us to remove the irq0 to CPU0 binding as well. Add a per cpu counter for irq0 and evaluate this instead of the global irq0 count in the nmi watchdog code.

2007-10-12x86_64: remove pit synchronizationThomas Gleixner
The APIC timer setup code synchronizes the local APIC timer to the PIT/HPET. This is pointless as the PIT and the local APIC timer frequency are not correlated and the APIC timer calibration can never be accurate enough to avoid that the local APIC timer and the PIT/HPET drift apart.

Add the x8664 specific bits (mapping) to share the hpet code later. Move the reserve_platform_timer call to late init. This is necessary for x86_64, as hpet enable() is called before memory is setup. i386 calls it in late_time_init, but it does not hurt to do it later for both.

The hpet implementations of i386 and x8664 has been mostly the same before the clock events conversion of i386. The clock events conversion of i386 hpet is already done.

arch/s390/Kconfig tells us that CONFIG_APPLDATA_BASE is bool and hence can never be built modular. Given this, defining appldata_exit() function is pointless (and wasteful, actually). Remove all that. Previous patch annotated appldata_offline_cpu() as __cpuexit, but now with the __exit function appldata_exit() gone, the only callsite that references it is __cpuinit, so this function can also be __cpuinit, thereby saving space when HOTPLUG_CPU=n.

2007-10-12[S390] appldata_base: Misc cpuinit annotations and bugfixSatyam Sharma
appldata_offline_cpu() is only called from __cpuinit-marked hotplug notifier callback and from the __exit-marked module_exit function, therefore candidate for __cpuexit. BTW the __exit module_exit function appldata_exit() of this driver fails to unregister_hotcpu_notifier() the notifier_block that was registered by appldata_init() during module startup. This will lead to oops if hotplug notification comes after module has been unloaded. Let's fix this by unregistering the notifier appropriately (before appldata_offline_cpu()'ing the CPUs).

2007-10-12[POWERPC] Add memchr() to the bootwrapperDavid Gibson
This adds a memchr() implementation to the bootwrapper, which will be needed when libfdt is merged in. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-10-12[POWERPC] Implement logging of unhandled signalsOlof Johansson
Implement show_unhandled_signals sysctl + support to print when a process is killed due to unhandled signals just as i386 and x86_64 does. Default to having it off, unlike x86 that defaults on. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-10-12[POWERPC] Add legacy serial support for OPB with flattened device treeValentine Barshak
Currently find_legacy_serial_ports() can find no serial ports on the OPB with flattened device tree. Thus no legacy boot console can be initialized. Just the early udbg console works, which is initialized with udbg_init_44x_as1 on the UART's physical address specified in kernel config. This happens because we look for ns16750 serial devices only and expect opb node to have a device type property. This patch makes it look for ns16550-compatible devices and use of_device_is_compatible() for opb in case device type is not specified.
