and then allocate it on demand. Rename some common symbols (__bss_start,
_edata, _end, __start_link_set_*, __stop_link_set_*) so that ".<module>"
is appended to them. This shrinks an amd64 kernel by 20KB of BSS.
symbols, and made it impossible for the kernel to use that value, and
correctly find symbols from LKMs.
o Allow LKM users to use DDB to debug the entry function of a LKM by
loading the symbol table with the temporary name /lkmtemp/ before calling
it, and then renaming it once we know the module name.

into compiled LKMs. Check this information when LKM is loaded into kernel
and refuse LKMs not matching currently running kernel. Provide LMFORCE
ioctl to skip this check for those feeling adventurous.
as discussed on tech-kern@, thanks to feedback from Bill Studenmund and others
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
in the event that it needs to use a special VM range (x86_64 falls
into this category). We fall back onto kernel_map if machine-dependent
code doesn't create a special map.
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)
unload, and stat functions. arguably could (should?) use NULL instead,
but this is a bit more descriptive. also, unconditionally call the
load/unload/stat functions, as now they're known to work (because, at
worst, they're lkm_nofunc).
