The commit partially restores the _ISR_Handler code to the original version in commitb8fc2de1ce. A list of reverted changes follows. commitc236082873Author: Sebastian Huber <sebastian.huber@embedded-brains.de> Date: Tue Jul 30 15:54:53 2013 +0200 smp: Provide cache optimized Per_CPU_Control Delete _Per_CPU_Information_p. This commit was completely reverted. commit39e51758c8Author: Sebastian Huber <sebastian.huber@embedded-brains.de> Date: Fri Jun 14 14:00:38 2013 +0200 smp: Add and use _CPU_SMP_Get_current_processor() Add and use _SMP_Get_current_processor() and rtems_smp_get_current_processor(). Delete bsp_smp_interrupt_cpu(). Change type of current processor index from int to uint32_t to match _SMP_Processor_count type. This commit was completely reverted. commite94aa61b68Author: Till Straumann <strauman@slac.stanford.edu> Date: Fri Aug 5 00:15:50 2011 +0000 2011-08-04 Till Straumann <strauman@slac.stanford.edu> * shared/irq/irq_asm.S: BUGFIX (introduced by SMP changes which moved code around, apparently): *must* store i8259 mask to frame *before* switching to IRQ stack. The code retrieves the mask after switching back to original stack. Also, the IRQ stack has no reserved space for the mask; storing it there could overwrite memory! This commit was completely reverted. commit01f2692e33Author: Jennifer Averett <Jennifer.Averett@OARcorp.com> Date: Mon Aug 1 13:41:50 2011 +0000 2011-08-01 Jennifer Averett <Jennifer.Averett@OARcorp.com> PR 1802 * shared/irq/irq_asm.S, shared/irq/irq_init.c, shared/smp/smp-imps.c, shared/smp/smp-imps.h: Add SMP support for i386. * shared/smp/getcpuid.c: New file. The parts modifying the code of _ISR_Handler were reverted. commit66729db311Author: Joel Sherrill <joel.sherrill@OARcorp.com> Date: Wed Mar 16 20:05:17 2011 +0000 2011-03-16 Jennifer Averett <jennifer.averett@OARcorp.com> PR 1729/cpukit * shared/irq/irq_asm.S: Add next step in SMP support. This adds an allocated array of the Per_CPU structures to support multiple cpus vs a single instance of the structure which is still used if SMP support is disabled. Configuration support is also added to explicitly enable or disable SMP. But SMP can only be enabled for the CPUs which will support it initially -- SPARC and i386. With the stub BSP support, a BSP can be run as a single core SMP system from an RTEMS data structure standpoint. This commit was completely reverted.
