write caching is disabled on both SCSI and IDE disks where large
memory dumps could take up to an hour to complete.
Taking an i386 scsi based system with 512MB of ram and timing (in
seconds) how long it took to complete a dump, the following results
were obtained:

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).
for large scsi disks with WCE = 0. This yields around a 7 times speedup
on elapsed newfs time on test disks here. 64k clusters seems to be the
sweet spot for scsi disks using our present drivers.
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..
This commit (in conjunction with setting MINSIGSTKSZ to 2048 &
rebuilding your kernel and modules) will get IBM's JDK 1.3 working
with FreeBSD at least well enough to run many of the example applets.

Without this patch, an SA_SIGINFO style handler can be installed by a linux
app, but if the handler accesses its sip argument, it will get a garbage
pointer and likely segfault.
We currently supply a valid pointer, but its contents are mainly
garbage. Filling this in properly is future work.
This is the second of 3 commits that will get IBM's JDK 1.3 working with

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).
