830e5f74ea 2001-05-14 Till Straumann <strauman@slac.stanford.edu> 
* cpu.c: Per PR211 fix
	saving/restoring floating point context.  The fpsave and fprestore
	routines are only used in a executing context which _is_ fp and hence
	has the FPU enabled. The current behavior required the FPU always to
	be on which is very dangerous if lazy context switching is used.
	[Joel Note: Some ports explicitly enabled the FPU in the FP save and
	restore routines to avoid this.]

	The patch also makes sure (on powerpc only) that the FPU is disabled
	for integer tasks. Note that this is crucial if deferred fp context
	switching is used. Otherwise, fp context corruption may go undetected!
	Also note that even tasks which merely push/pop FP registers to/from
	the stack without modifying them still MUST be FP tasks - otherwise
	(if lazy FP context switching is used), FP register corruption (of
	other, FP, tasks may occur)!

	Furthermore, (on PPC) by default, lazy FP context save/restore
	is _disabled_.

This was tracked as PR91.
	* rtems/score/cpu.h: Added CPU_PROVIDES_ISR_IS_IN_PROGRESS macro which
	is used to specify if the port uses the standard macro for this (FALSE).
	A TRUE setting indicates the port provides its own implementation.
	* rtems/score/c_isr.inl: Deleted and contents merged into cpu.c.
	* cpu.c: Received contents of c_isr.inl.
	* Makefile.am: Deleted reference to c_isr.inl.
