Michael Brown ea203e4fe1 [librm] Add phys_call() wrapper for calling code with physical addressing Add a phys_call() wrapper function (analogous to the existing real_call() wrapper function) for calling code with flat physical addressing, and use this wrapper within the PHYS_CODE() macro. Move the relevant functionality inside librm.S, where it more naturally belongs. The COMBOOT code currently uses explicit calls to _virt_to_phys and _phys_to_virt. These will need to be rewritten if our COMBOOT support is ever generalised to be able to run in a 64-bit build. Specifically: - com32_exec_loop() should be restructured to use PHYS_CODE() - com32_wrapper.S should be restructured to use an equivalent of prot_call(), passing parameters via a struct i386_all_regs - there appears to be no need for com32_wrapper.S to switch between external and internal stacks; this could be omitted to simplify the design. For now, librm.S continues to expose _virt_to_phys and _phys_to_virt for use by com32.c and com32_wrapper.S. Similarly, librm.S continues to expose _intr_to_virt for use by gdbidt.S.
