* [PATCH] snsc: switch from force_sig to kill_procChristoph Hellwig2006-07-101-14/+1
| | | | | | | | | | | | | | | | | | | Currently the snsc driver uses force_sig to send init a SIGPWR when the system overheats. This patch switches it to kill_proc instead which has the following advantages: (1) gets rid of one of the last remaining tasklist_lock users in modular code (2) simplifies the snsc code significantly The downside is that an init implementation could in theory block SIGPWR and it would not get delivered. The sysvinit code used by all major distributions doesn't do this and blocking this signal in init would be a rather stupid thing to do.

* [IA64-SGI] Handle SC env. powerdown eventsAaron Young2006-01-261-8/+24
| | | | | | | | | | Handle system controller power down pending events on SN systems. This allows the system to gracefully shutdown before the system controller removes power due to an adverse environmental condition.

* [IA64-SGI] fix unaligned memory access in snsc_event.cGreg Howard2005-08-151-3/+8
| | | | | | | | | | | | | It's been pointed out that environmental events from the system controllers on Altix machines cause the kernel to complain about unaligned memory accesses. This turns out to be because "be32_to_cpup()" didn't do everything I thought/hoped it did. I've added calls to pull the offending integers out of the buffers using get_unaligned() before feeding them to be32_to_cpup().
