allocation is now cache aligned. The cache functions are
currently not available on all platforms so the cache line size is
fixed to 32 bytes for now. Changed various integer types which
refer to block sizes, numbers and indexes. Fixed logical block
indexes in buffer get and read function. It is now possible to
delete logical disks. Modified documentation

in the main configuration table. Reference the main configuration
table and the API configuration tables directly using the confdefs.h
version rather than obtaining a pointer to it. This eliminated some
variables, a potential fatal error, some unnecessary default
configuration structures. Overall, about a 4.5% reduction in the code
size for minimum and hello on the SPARC.
* sapi/include/confdefs.h: Add disable of pipes by default since they
use resources which are otherwise not accounted for. Eventually the
resources will have to be properly configured.

* libblock/include/rtems/bdbuf.h, cpukit/libblock/src/bdbuf.c:
Rewritten the bdbuf code. Remove pre-emption disable, score

* libblock/include/rtems/blkdev.h: Added
RTEMS_BLKDEV_CAPABILITIES block device request. Cleaned up
comments. Added block and user fields to the sg buffer
request. Move to rtems_* namespace.
* libblock/include/rtems/diskdevs.h,
cpukit/libblock/src/diskdevs.c: Move to rtems_* namespace. Add a

release a disk, you obtain and release a disk.
* libblock/include/rtems/ide_part_table.h,

struct. This allows non-continuous buffer requests for those
drivers that can support increasing performance.
* libblock/src/nvdisk.c: Move to rtems_* namespace. Removed

* libmisc/shell/shell.c: Change shell tasks mode to be timeslice
and no ASR.
* sapi/include/confdefs.h: Change ata_driver_task_priority to
rtems_ata_driver_task_priority. Add the new BD buf cache
parameters with defaults.
* score/src/interr.c: Do not return if the CPU halt call returns.
* sapi/include/confdefs.h: When you disabled newlib reentrancy, it
still reserved memory for the reentrancy structure. This is about 1K
per task. On psim, we now reserve only 1936 bytes and only 240 remain
after all allocations. Further analysis will be required to narrow
that down. In addition, the new constant CONFIGURE_CONFDEFS_DEBUG can
be defined and the structure named Configuration_Memory_Debug will be
instantiated. This structure contains many of the component values
that go into the memory reservation computation. This is helpful when
tracking down problems.
* sapi/include/confdefs.h: The math in the _Configure_Object_RAM macro
was always adding heap overhead even when the number of objects
configured was zero and we would not do an allocation. This resulted
in an over estimation of the amount of Workspace required (~2K on
minimum.exe on PowerPC).
* cpukit/sapi/include/confdefs.h: Add missing quote to string to
remove warning.
* cpukit/score/cpu/m68k/rtems/score/m68k.h: Add the default
priority level for large memory Coldfires.

ability for application to configure minimum stack size. Add
RTEMS_CONFIGURED_MINIMUM_STACK_SIZE constant so user can clearly
indicate they want the configured as opposed to the recommended
minimum stack size.
* sapi/include/confdefs.h: Rework to be more accurate on allocation. In
particular, there was a report from that Matthew Riek that memory was
being reserved twice for the IDLE task. This was covering up other
places that under allocated memory. Before I was done, I had reworked
the file to be easier to read, maintain and be more accurate.
reduce size of data area.
IMFS: Fixed creation of symbolic links to avoid a compiler warning.
DOSFS: Use LibBlock instead of read() to read the boot record.
* libmisc/dummy/dummy.c, sapi/include/confdefs.h: Add checks for
application configuration errors. If any POSIX objects or a POSIX
init thread is configured without POSIX being configure, then error
out. Similarly for ITRON. Add
CONFIGURE_APPLICATION_DOES_NOT_NEED_CLOCK_DRIVER configuration
parameter so the application has to explicitly configure the Clock
driver in or out if the Timer driver is not configured. Also verify
RTEMS was built for multiprocessing, if the user tries to configure a
multiprocessing application.
* sapi/include/confdefs.h: Do not reserve 2 * minimum stack size
for the ITRON initialization tasks ALL the time.
Do not reserve memory for the object name table since it does not
exist any longer.
* sapi/include/rtems/sptables.h: Fix typo.
* sapi/include/confdefs.h, score/src/mpci.c, score/src/objectmp.c,
score/src/objectnametoid.c, score/src/objectnametoidstring.c:
Multiprocessing compiles again and survives initialization. The
recent object name and confdefs.h changes had broken it.

* libcsupport/include/rtems/malloc.h,
libcsupport/src/malloc.c, libcsupport/src/malloc_initialize.c,
libcsupport/src/malloc_p.h,
libcsupport/src/malloc_statistics_helpers.c: Make sbrk()
support pluggable and optional. This eliminates the need for
heap extend and sbrk in the minimum footprint which is ~2.5K on
the SPARC.
* sapi/include/confdefs.h: Add the following configuration points:
+ CONFIGURE_MALLOC_STATISTICS
+ CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK
* libcsupport/src/malloc_sbrk_helpers.c: New file.
* sapi/include/confdefs.h, sapi/include/rtems/config.h,

predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
extra_mpci_receive_server_stack, stack_allocate_hook, and
stack_free_hook. As a side-effect of this effort some multiprocessing
code was made conditional and some style clean up occurred.
