Renamed shm.h to shm_driver.h to avoid conflicts with POSIX shm.h.

Browse Source 
Renamed file shmsupp/intr.c in some BSPs to shmsupp/cause_intr.c to
avoid conflict with rtems/src/intr.c (Classic API Interrupt Manager).

/* The information contained in the Node Status, Locked Queue, and

* NOTE: XXX
* PORTABILITY OF LOCKING INSTRUCTIONS
* ===================================
* The locking mechanism described below is not
* general enough. Where the hardware supports
* it we should use "atomic swap" instructions
* so the values in the lock can be tailored to
* support a CPU with only weak atomic memory
* instructions. There are combinations of
* CPUs with inflexible atomic memory instructions
* which appear to be incompatible. For example,
* the SPARClite instruction uses a byte which is
* 0xFF when locked. The PA-RISC uses 1 to indicate
* locked and 0 when unlocked. These CPUs appear to
* have incompatible lock instructions. But
* they could be used in a heterogenous system
* with does not mix SPARCs and PA-RISCs. For
* example, the i386 and SPARC or i386 and SPARC
* could work together. The bottom line is that
* not every CPU will work together using this
* locking scheme. There are supposed to be
* algorithms to do this without hardware assist
* and one of these should be incorporated into
* the shared memory driver.
*
* The most flexible scheme using the instructions
* of the various CPUs for efficiency would be to use
* "atomic swaps" wherever possible. Make the lock
* and unlock configurable much like BIG vs LITTLE
* endian use of shared memory is now. The values
* of the lock could then reflect the "worst"
* CPU in a system. This still results in mixes
* of CPUs which are incompatible.
*
* The current locking mechanism is based upon the MC68020
* "tas" instruction which is atomic. All ports to other CPUs
* comply with the restrictive placement of lock bit by this
* instruction. The lock bit is the most significant bit in a
* big-endian rtems_unsigned32. On other processors, the lock is
* typically implemented via an atomic swap or atomic modify
* bits type instruction.

* The following are the values used to fill in the lock field. Some CPUs
* are able to write only a single value into field. By making the
* lock and unlock values configurable, CPUs which support "atomic swap"
* instructions can generally be made to work in any heterogeneous
* configuration. However, it is possible for two CPUs to be incompatible
* in regards to the lock field values. This occurs when two CPUs
* which write only a single value to the field are used in a system
* but the two CPUs write different incompatible values.
*
* NOTE: The following is a first attempt at defining values which
* have a chance at working together. The m68k should use
* chk2 instead of tas to be less restrictive. Target endian
* problems (like the Force CPU386 which has (broken) big endian
* view of the VMEbus address space) are not addressed yet.
