services or PAL procedures. The new implementation is based on specific functions that are known to be called in certain scenarios only. This in particular fixes the PAL call to obtain information about translation registers. In general, the new implementation does not bank on virtual addresses being direct-mapped and will work when the kernel uses PBVM. When new scenarios need to be supported, new functions are added if the existing functions cannot be changed to handle the new scenario. If a single generic implementation is possible, it will become clear in due time. While here, change bootinfo to a pointer type in anticipation of future development.
