Strictly speaking this is unnecessary, but it allows nanobsd to work
on systems from before the -x and -y arguments to mdconfig(8) worked
for vnode backing.

from the gdb(1) register number to offsets within struct reg and
struct fpreg. The tool is useful only on selected platforms. On
ia64 the registers are all over the place to simplify handling of
them in various situations, but which makes creating or maintaining
such an offset table error prone to do by hand.
Since remote kernel debugging operates on the same register numbers,
it would be a natural choice to use an identical offset table in the
kernel. However, since the kernel does not operate on struct reg nor
struct fpreg in the remote gdb(1) case, such would not make sense.
Whether we want to use this tool to create offsets for use in the
kernel or duplicate the knowledge of which register number maps to
what register is something that will become clear soon.
Note: in order to build cross debuggers, one cannot use target
headers and/or target definitions. That's why offsets need to be
hardcoded in the first place. Unpleasant, but necessary.
are supposed to continue firing as long as there is work to do, not
stop after the first invocation.
This is damage control after a patch that has been committed prematurely.
Tested by: kris
(if any) and exit, thus matching the behavior on -stable and other OS's.
My earlier attempt to fix this (v1.65) only seemed to work because of a
lucky random value in nentries (which was not being initialized back
when I tested that earlier patch).
is compiled with LAZY_PS, so that there is only one PS_ARGS string to

usage() statement when compiled with LAZY_PS.
instead of ephemeral mappings using pmap_qenter() by the writer. The
writer is still, however, responsible for wiring the pages, just not
mapping them. Consequently, the allocation of KVA for the direct case is
unnecessary. Remove it and the sysctls limiting it, i.e.,
kern.ipc.maxpipekvawired and kern.ipc.amountpipekvawired. The number
of temporarily wired pages is still, however, limited by
kern.ipc.maxpipekva.
Note: On platforms lacking a direct virtual-to-physical mapping,
uiomove_fromphys() uses sf_bufs to cache ephemeral mappings. Thus,
the number of available sf_bufs can influence the performance of pipes
on platforms such i386. Surprisingly, I saw the greatest gain from this
change on such a machine: lmbench's pipe bandwidth result increased from
~1050MB/s to ~1850MB/s on my 2.4GHz, 400MHz FSB P4 Xeon.
- Change `-p' to allow a list of process IDs, and `-t' to allow a list
of terminal names, instead of only a single value for each.
- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
and have `ps' keep adding to a given list -- instead of replacing the
previously-specified values.
- Fix interactions between selector-options, so that: "If any are
specified, ... ps shall select the processes represented by the
inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.
- various minor improvements in parsing and error handling.
This does not get us to match POSIX/SUSv3, but it gets us closer. The
`-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
freebsd-standards are still under debate, so they skipped for now.
It should be true that this introduces no user-visible incompatible
changes, except to support "new stuff" that was not supported before.
long as there are still explicit uses of int, whether in types or
in function names (such as atomic_set_int() in sched_ule.c), we can
not change cpumask_t to be anything other than u_int. See also the
commit log for sys/sys/types.h, revision 1.84.
