* x86: Geode MFGPT clock event device supportAndres Salomon2007-10-12
| | | | | | | | | | | | | | | Add support for an MFGPT clock event device; this allows us to use MFGPTs as the basis for high-resolution timers.

* x86: Geode Multi-Function General Purpose Timers supportAndres Salomon2007-10-12
| | | | | | | | | | | | | | | | | | | This adds support for Multi-Function General Purpose Timers. It detects the available timers during southbridge init, and provides an API for allocating and setting the timers. They're higher resolution than the standard PIT, so the MFGPTs come in handy for quite a few things. Note that we never clobber the timers that the BIOS might have opted to use; we just check for unused timers.

* x86: Fix irq0 / local apic timer accountingThomas Gleixner2007-10-12
| | | | | | | | | | | | | | | | | | | | | | 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.

| * [POWERPC] Add legacy serial support for OPB with flattened device treeValentine Barshak2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [POWERPC] Use 1TB segmentsPaul Mackerras2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the kernel use 1TB segments for all kernel mappings and for user addresses of 1TB and above, on machines which support them (currently POWER5+, POWER6 and PA6T). We detect that the machine supports 1TB segments by looking at the ibm,processor-segment-sizes property in the device tree. We don't currently use 1TB segments for user addresses < 1T, since that would effectively prevent 32-bit processes from using huge pages unless we also had a way to revert to using 256MB segments. That would be possible but would involve extra complications (such as keeping track of which segment size was used when HPTEs were inserted) and is not addressed here. Parts of this patch were originally written by Ben Herrenschmidt. Signed-off-by: Paul Mackerras <paulus@samba.org>
