[PATCH] cyclone: PIT sanity checking
From: john stultz <johnstul@us.ibm.com> In testing for SLES9, we ran across a bug caused by userspace apps poking the PIT which caused bad values to be read by the kernel. This would then trigger the lost tick detection code with insane values and would then break the SCSI subsystem. This patch includes the PIT sanity check from the TSC timesource into the cyclone timesource code, which catches the bad case described above and resolves the issue.
