Add new -k (for kernel modules) flag to return MM.99.pp for current and MM.mm
for the release branch.

Don't eat _BETA. I am sure dsl will come up with something more elegant.

Fix borkeage

Get patch part of version from comment.

Use shell builtins instead of awk and sed.
Avoids problems with awk processing floating point numbers when LC_NUMERIC
give a decimal point of ','.
Fixes PR/42321

Describe new -n option in a comment; improve description of -m option.

Add -n option to print major and minor version, e.g. 5.99 on -current.

branches: 1.115.4; 1.115.10; 1.115.14;
Use ${TOOL_SED}, which is defined by bsd.own.mk/bsd.sys.mk,
instead of just ${SED}. (Don't do the same for ${AWK},
because that's not yet a host tool.)

Per request from Matt Thomas, make -m on -current print the major
number of the next release.

1) replace use of sed with $SED
2) get rid of grep variable -- grep isn't used here
3) add a -m option that prints the release major number (like "4")
4) add a comment documenting the options

Remove the remains of an old comment that doesn't apply any more.

Welcome to 1.6ZC

Bump version to 1.6ZA - struct proc and struct lwp changes
Deja vu ...

welcome to 1.6Z

welcome to 1.6Y (for inpcb/in6pcb change)

bump kernel version to 1.6X for systrace changes

bump kernel version to 1.6W, because of vnode/namecache changes.
(skip 1.6V to avoid confusion.)

pointed by Love.

branches: 1.99.2;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
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

Bump version to 1.6U, because of PCI attach args changes.

Bump version to 1.6T:

Back out the following chagne:
http://mail-index.netbsd.org/source-changes/2003/05/08/0068.html

There were some side-effects that I didn't anticipate, and fixing them
is proving to be more difficult than I thought, do just eject for now.
Maybe one day we can look at this again.

Fixes PR kern/21517.

Simplify the way the bounds of the managed kernel virtual address
space is advertised to UVM by making virtual_avail and virtual_end
first-class exported variables by UVM. Machine-dependent code is
responsible for initializing them before main() is called. Anything
that steals KVA must adjust these variables accordingly.

This reduces the number of instances of this info from 3 to 1, and
simplifies the pmap(9) interface by removing the pmap_virtual_space()
function call, and removing two arguments from pmap_steal_memory().

This also eliminates some kludges such as having to burn kernel_map
entries on space used by the kernel and stolen KVA.

This also eliminates use of VM_{MIN,MAX}_KERNEL_ADDRESS from MI code,
this giving MD code greater flexibility over the bounds of the managed
kernel virtual address space if a given port's specific platforms can
vary in this regard (this is especially true of the evb* ports).

Bump to 1.6R -- mbuf and pool changes.

Bump version to 1.6Q - for struct proc and struct pgrp change

Add MBUFTRACE kernel option.
Do a little mbuf rework while here. Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *). These are not performance critical and making them
call m_get saves considerable space. Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.

Add code to UBCify LFS. This is still behind "#ifdef LFS_UBC" for now
(there are still some details to work out) but expect that to go
away soon. To support these basic changes (creation of lfs_putpages,
lfs_gop_write, mods to lfs_balloc) several other changes were made, to
wit:

* Create a writer daemon kernel thread whose purpose is to handle page
writes for the pagedaemon, but which also takes over some of the
functions of lfs_check(). This thread is started the first time an
LFS is mounted.

* Add a "flags" parameter to GOP_SIZE. Current values are
GOP_SIZE_READ, meaning that the call should return the size of the
in-core version of the file, and GOP_SIZE_WRITE, meaning that it
should return the on-disk size. One of GOP_SIZE_READ or
GOP_SIZE_WRITE must be specified.

* Instead of using malloc(...M_WAITOK) for everything, reserve enough
resources to get by and use malloc(...M_NOWAIT), using the reserves if
necessary. Use the pool subsystem for structures small enough that
this is feasible. This also obsoletes LFS_THROTTLE.

And a few that are not strictly necessary:

* Moves the LFS inode extensions off onto a separately allocated
structure; getting closer to LFS as an LKM. "Welcome to 1.6O."

* Unified GOP_ALLOC between FFS and LFS.

* Update LFS copyright headers to correct values.

* Actually cast to unsigned in lfs_shellsort, like the comment says.

* Keep track of which segments were empty before the previous
checkpoint; any segments that pass two checkpoints both dirty and
empty can be summarily cleaned. Do this. Right now lfs_segclean
still works, but this should be turned into an effectless
compatibility syscall.

Bump version to 1.6N; extensible malloc types.

Bump kernel version to 1.6M -- nathanw_sa branch merge. (M for
multi-lwp processes? :-)

bump kernel version - struct fileops change

1.5T -- PR_ABRTACPTDIS in protosw.

branches: 1.65.2;
Support flexible process address space limits and bump kernel version number.

1.5R -- sy_flags added to struct sysent.

Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

bump kernel version to 1.5P - struct proc, struct sigacts changes

Bump the kernel version cause we changed the line disciplines interface.

NetBSD 1.5H: struct ifnet changed.

Add support for variable end of user stacks needed to support COMPAT_NETBSD32:

`struct vmspace' has a new field `vm_minsaddr' which is the user TOS.

PS_STRINGS is deprecated in favor of curproc->p_pstr which is derived
from `vm_minsaddr'.

Bump the kernel version number.

VOP_FSYNC interface change -> 1.5F

Remove the "kprintf" gcc attribute permanently. Use standard "printf"
format checking. We are now at 1.5E, as the removal of %b will cause
third-party LKMs to break.

1.5D == namei pathname buffer allocation is pool'ified.

bump to 1.5C - lf_advlock() change

We are now at 1.5B because of the removal of <vm/*>.

NetBSD 1.4Q -- buffer queue changes.

kernel interface changed, bup version number (what will come after
1.4Z ? :)

Add Kirk McKusick's soft updates code to the trunk. Not enabled by
default, as the copyright on the main file (ffs_softdep.c) is such
that is has been put into gnusrc. options SOFTDEP will pull this
in. This code also contains the trickle syncer.

Bump version number to 1.4O

Hello 1.4N! (pmap_enter() API change)

Up the size of the ifa_flags and ifa_refcnt from shorts to ints. Now will
deal correctly with more than 32767 routes out an interface.

Make unionfs set v_vnlock = NULL so any overlayed fs will call its
VOP_LOCK.

Implement method to store release information in one location; it's
generated by `osrelease.sh`. If an argument of "-s" is given, print
the "short" form (e.g, "12E"), otherwise print the long (e.g, "1.2E").
Take advantage of this in newvers.sh.
