Summary:

kernel (new function): Support for clock synchronization to an external time reference (ETR).

Description:

This patch adds support for clock synchronization to an external time reference (ETR). The external time reference sends an oscillator signal and a synchronization signal every 2**20 (2 to the power of 20) microseconds to keep TOD clocks of all connected servers in sync. For availability two ETR units can be connected to a machine. If the clock deviates for more than the sync-check tolerance all CPUs get a machine check that indicates that the clock is out of sync. If this happens all DASD I/O to XRC enabled devices is stopped until the clock is synchronized again. The ETR support is activated via two sysfs attributes: echo 1 > /sys/devices/system/etr/etr0/online echo 1 > /sys/devices/system/etr/etr1/online

This patch needs an upstream sysfs patch as prerequisite. The upstream patch with git ID 670dd90d81f60ef429cbba54ad235e9207f4d444 needs to be applied before this add-on patch:
www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=670dd90d81f60ef429cbba54ad235e9207f4d444;hp=1740757e8f94c6899705eb6f5434de9404992778

Note that this patch provides a recommended (optional) add-on to the "October 2005 stream", to be applied as last patch on top of patch 13 (or later) and on top of the upstream sysfs patch.
