Add ISR lock to chain control for proper SMP protection. Replace
rtems_chain_extract() with rtems_chain_explicit_extract() and
rtems_chain_insert() with rtems_chain_explicit_insert() on SMP
configurations. Use rtems_chain_explicit_extract() and
rtems_chain_explicit_insert() to provide SMP support.
Delete _Priority_bit_map_Handler_initialization() and rely on BSS
initialization. Move definition of _Priority_Major_bit_map and
_Priority_Bit_map to separate file. Move definition of __log2table also
to this file.
Change pthread_once from using disabled pre-emption to using a
pthread mutex making it SMP safe. GCC using a posix threading
model uses pthread_once.
The pthread mutex requires at least 1 mutex is configured so
confdefs.h has been updated to account for the internal
mutex.
Add context parameter to _Thread_Start_multitasking() and use this
function in rtems_smp_secondary_cpu_initialize(). This avoids
duplication of code.
Fix missing floating point context initialization in
rtems_smp_secondary_cpu_initialize(). Now performed via
_Thread_Start_multitasking().
Move implementation specific parts of object.h and object.inl into new
header file objectimpl.h. The object.h contains now only the
application visible API.

header file threadimpl.h. The thread.h contains now only the
application visible API.
Remove superfluous header file includes from various files.
Move implementation specific parts of prioritybitmap.h and
prioritybitmap.inl into new header file prioritybitmapimpl.h. The
prioritybitmap.h contains now only the application visible API.
Move content of bitfield.h into prioritybitmapimpl.h.
Move implementation specific parts of scheduler.h and scheduler.inl into
new header file schedulerimpl.h. The scheduler.h contains now only the
application visible API.
Move implementation specific parts of tasks.h and tasks.inl into new
header file tasksimpl.h. The tasks.h contains now only the application
visible API.
Move implementation specific parts of region.h and region.inl into new
header file regionimpl.h. The region.h contains now only the
application visible API.
Move implementation specific parts of timer.h and timer.inl into new
header file timerimpl.h. The timer.h contains now only the application
visible API.
Move implementation specific parts of ratemon.h and ratemon.inl into
new header file ratemonimpl.h. The ratemon.h contains now only the
application visible API.
Move implementation specific parts of dpmem.h and dpmem.inl into new
header file dpmemimpl.h. The dpmem.h contains now only the application
visible API.
Move implementation specific parts of event.h, event.inl, eventset.h and
eventset.inl into new header file eventimpl.h. The event.h contains now
only the application visible API.
Move implementation specific parts of status.h and status.inl into new
header file statusimpl.h. The status.h contains now only the
application visible API.
Move implementation specific parts of extension.h and extension.inl into
new header file extensionimpl.h. The extension.h contains now only the
application visible API.
Move implementation specific parts of watchdog.h and watchdog.inl into
new header file watchdogimpl.h. The watchdog.h contains now only the
application visible API.
Move implementation specific parts of spinlock.h and spinlock.inl into
new header file spinlockimpl.h. The spinlock.h contains now only the
application visible API.
Move implementation specific parts of timer.h and timer.inl into new
header file timerimpl.h. The timer.h contains now only the application
visible API.
Move implementation specific parts of rwlock.h and rwlock.inl into new
header file rwlockimpl.h. The rwlock.h contains now only the
application visible API.
Move implementation specific parts of pthread.h and pthread.inl into new
header file pthreadimpl.h. The pthread.h contains now only the
application visible API.
Move implementation specific parts of priority.h and priority.inl into
new header file priorityimpl.h. Remove priority.h since there is no
application visible API.
Move implementation specific parts of barrier.h and barrier.inl into new
header file barrierimpl.h. The barrier.h contains now only the
application visible API.
Move implementation specific parts of barrier.h and barrier.inl into new
header file barrierimpl.h. The barrier.h contains now only the
application visible API.
Move implementation specific parts of mqueue.h and mqueue.inl into new
header file mqueueimpl.h. The mqueue.h contains now only the
application visible API.
Move implementation specific parts of message.h and message.inl into new
header file messageimpl.h. The message.h contains now only the
application visible API.
Move implementation specific parts of semaphore.h and semaphore.inl into
new header file semaphoreimpl.h. The semaphore.h contains now only the
application visible API.
Move implementation specific parts of mutex.h and mutex.inl into new
header file muteximpl.h. The mutex.h contains now only the application
visible API.
Add and use _Objects_Put_without_thread_dispatch(). These two functions
pair with the _Objects_Get() function. This helps to introduce object
specific SMP locks to avoid lock contention.
This field is unused except for special case simulator clock drivers.
In these places use an alternative. Add and use
_Thread_Set_global_exit_status() and _Thread_Get_global_exit_status().
Call _SMP_Handler_initialize() later and move bsp_smp_initialize() into
_SMP_Handler_initialize(). Change bsp_smp_initialize() prototype to
match integer types of calling context.
Delete rtems_configuration_get_smp_maximum_processors(). Delete
rtems_configuration_smp_maximum_processors variable. Add
maximum_processors field to rtems_configuration_table if RTEMS_SMP is
defined. Add rtems_configuration_get_maximum_processors().
Do not return from rtems_initialize_start_multitasking() and call
rtems_fatal() instead with a fatal source of RTEMS_FATAL_SOURCE_EXIT and
a fatal code with the exit status.
Remove all bsp_cleanup() functions. The boot_card() is now a no return
function.
