/foo/ {p;d}
Fill in netbsd32_vm_default_addr, and provide

Comment out the ieee fp flags for alpha for now - something (tm) is not
working right, see PR port-alpha/48782.
sun4v: the trap base address should be assigned to %l1 so %tba is properly setup later in the code - now the kernel gets as far as printing the copyright disclaimer, kernel version and total and available memory before crashing
As discussed on tech-toolchain, offer a new make variable MKKDEBUG - if
set to "yes", kernel builds will gain debug info and a netbsd.gdb will
be created (same as adding "makeoptions DEBUG=-g" to the config file).
Add two new options, -U and -D, that can be used to define "makeoptions"
on the config command line. While there, rename the undocumented (internal)
parser debug option from -D to -d.
Discussed on tech-toolchain.
Use the new -U option for config to avoid generating kernel debug info
during release builds. This should save quite some space in the evbarm
build, where makeoptions DEBUG is heavily used.
Add a new action kernel.gdb=MYCONF to build a kernel with debuginfo
(and generate netbsd.gdb)
Add TDB lines
exywdt -> exyowdt

include string.h for memset
Use the hypervisor to copy/zero pages. This saves us the extra overheads
of setting up temporary kernel mapping/unmapping.

riz@ reports savings of about 2s on a 120s kernel build.
Fix firmware path - noted by Thomas Mueller on current-users.
