[PATCH] Allow early access to the power management timer
Allow early access to the power management timer by exposing the verified read function and providing a helper function which checks the pmtmr_ioport variable and returns either the pm timer readout or 0 in case the pm timer is not available. Create a new header file and replace also the ifdef'ed extern definition in arch/i386/kernel/acpi/boot.c This is a preperatory patch for the rework of the local apic timer calibration. No functional changes.
