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.
