45b5bdc5e5 Split off the pm_entries array from the rest of struct pmap. This makes 
memory allocation for it more efficient (since pm_entries is 4096 bytes long),
and will allow pm_entries to be freed for swapped processes.

8ec27f2ebe Implementation of fiq_{get,set}regs.

9aa4896361 More FIQ support. This gives me enough to handle FIQs, and to downgrade them 
to IRQs as necessary.  All these interfaces are subject to change in the light

8b7128e398 Changes in aid of FIQ support: 
Add ioc_fiq_setmask().
  Change ioc_irq_status_full() to use the request registers rather than the
  status registers.  This is brings it into line with the Unix baclplane, and
  makes detecting downgraded FIQs possible.

bjh21
ddf906b00d Use ld -N (OMAGIC), since this saves the 32k of RAM (by not putting a gap 
between text and data) and means that loadfile only needs one backward seek
to load the file rather than two (which is important for gzipped kernels).

9315195522 Simple library to interface stand-alone programs to RISC OS. 
This comes in two parts:  riscoscalls.[Sh] provide definitions, and thin
wrappers around RISC OS SWIs (in the style of OsLib) for the use of both the
rest of the library and client code.  The rest of the library provides a
compatibility layer for libsa.

ce0ec1e208 Add System V semaphore resource limits to each GENERIC file that has an 
option for System V semaphores.  It appears that there are no overrides
in the code and each file has the following added.

 options    SYSVSEM     # System V semaphores
+#options   SEMMNI=10   # number of semaphore identifiers
+#options   SEMMNS=60   # number of semaphores in system
+#options   SEMUME=10   # max number of undo entries per process
+#options   SEMMNU=30   # number of undo structures in system
 options    SYSVSHM     # System V shared memory

If anyone thinks that this is incorrect for any of these files, please
correct it.

Note - the i386 port was not forgotten.  It was done separately.

ca5de264b4 Change the structure of a bus_space_handle_t in a desperate bid to avoid using 
function pointers.  It now contains two base addresses, one for 8-bit

to handle the Castle EtherSCSI card, which uses and address line to select
transfer width to the i82595.

2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

5871b80f00 Use uvm_pageboot_alloc() for early memory allocation, rather than 
calling pmap_steal_memory() directly.  On these platforms, since
uvm_pageboot_alloc() is a wrapper around pmap_steal_memory(), there
is no functional change.  This is merely for API consistency.

cfb5c7ed9f Make pmap_virtual_space() a required pmap function, even on platforms 
which have pmap_steal_memory().  This is to reduce the API differences
between pmaps that implement pmap_steal_memory() and pmaps which do
not.

Note that pmap_steal_memory() needs to adjust *vstartp and/or
*vendp only if it used addresses within the range provided to UVM
via the pmap_virtual_space() call.  I.e. it is not necessary to do
so in any current pmap_steal_memory() implementation.
