Add bus_generic_rl_{get,set,delete,release,alloc}_resource() functions
which provide generic operations for devices using resource list style
resource management.
This should simplify a number of bus drivers. Further commits to follow.

This doesn't work with 16bit pccards under NEWCARD.
Enable in your config by having "device pccbb" and "device cardbus".
(A "device pccard" will attach a pccard bus, but it means you system have
a high chance of panicing when a 16bit card is inserted)
It should be fairly simple to make a driver attach to cardbus under
NEWCARD -- simply add an entry for attaching to cardbus on a new
DRIVER_MODULE and add new device IDs as necessary. You should also make
sure the card can be detached nicely without the interrupt routine doing
something weird, like going into an infinite loop. Usually that should
entail adding an additional check when a pci register or the bus space is
read to check if it equals 0xffffffff.
Any problems, please let me know.

o Remember the resources we allocate for the config entry.
o When we get the resource, do an resource_list_add and do a
resource_list_delete if we fail later in the resource list.
o In the pccard bus, we allocate the resources. When a child asks for
them, just return the resources that we allocated (thanks to Paul
Richards and Mike Smith for the idea).
stacks near the top of their address space. If their TOS is greater
than vm_maxsaddr, vm_map_growstack() will confuse the thread stack
with the process stack and deliver a SEGV if they attempt to grow the
thread stack past their current stacksize rlimit. To avoid this,
adjust vm_maxsaddr upwards to reflect the current stacksize rlimit
rather than the maximum possible stacksize. It would be better to
adjust the mmap'ed region, but some apps (again, IBM's JDK 1.3) do not
check mmap's return value..

Without this patch, an SA_SIGINFO style handler can be installed by a linux

We currently supply a valid pointer, but its contents are mainly

Doug really came up with the fix, I'm just the monkey typing. Doug says:
The alpha can only support 64k of globals with $gp pointing at
base+32k so that the code can use 16bit signed offsets from $gp to
access it. .... it is possible to have multiple .got subsections
and the linker handles this with the relocations for 'ldgp' pseudo
instructions. [Without this patch] the code in exception.s has been
linked to use a different gp from locore.s (where pal_kgp is set).
