Public Member Functions inherited from Utcb
unsigned	ind2fp (unsigned ofs)
	Converts index to UTCB data to UTCB "frame pointers".
unsigned	fp2ind (unsigned fp)
	Converts UTCB "frame pointer" to index to UTCB data area.
unsigned	get_stack_top ()
	Returns the index to UTCB data area of the first empty word above the UTCB stack area.
void	set_stack_top (unsigned ofs)
	Sets the "top pointer" of the UTCB stack area.
Frame	get_nested_frame ()
unsigned	frame_words ()
	Returns the number of words needed for storing the current UTCB content to a UTCB frame as implemented in add_frame().
Utcb &	add_frame ()
	Push UTCB header and data to a stack area in the UTCB.
void	skip_frame ()
void	drop_frame ()
	Restore UTCB to the state saved by the last add_frame() and remove the restored state from the stack area.

WARN_UNUSED unsigned long	add_mappings (unsigned long addr, unsigned long size, unsigned long hotspot, unsigned rights, bool frame=false, unsigned max_items=sizeof(msg)/sizeof(msg[0])/2)
	Add mappings to a UTCB.
void	reset ()
	If you mixing code which manipulates the utcb by its own and you use this Utcb/Frame code, you have to fix up your utcb after the code manipulated the utcb by its own.
