Modified files:
sys/dev/acpica acpi_timer.c
Log:
Implement a "proper" timecounter hung off the ACPI timer device.
This code is based on the mp_clock code by phk. It attempts to
detect the PIIX4 (see comments for details) and use a workaround
for its problems.
This code is experimental, and could use some testing and review by a
timekeeping enthusiast.
