CVS commit: src/sys/dev/acpi

[Jukka Ruohonen]

Module Name:    src
Committed By:   jruoho
Date:           Fri Feb 18 07:00:05 UTC 2011

Modified Files:
        src/sys/dev/acpi: acpi_cpu_tstate.c

Log Message:
Remove the (debug) check that evaluated whether the first T-state (i.e. the
100 % duty cycle) had control value of zero, as in the IA32 clock modulation
MSR. As the access may be based on I/O, it is unclear if a strict validation
like this was correct. Should fix the problem reported by Hisashi T Fujinaka
on current users.
