the holes a MMU may have from a given vm_map. This will be automagically
invoked for newly created vmspaces.
On platforms with MMU holes (e.g. sun4, sun4c and vax), this prevents
mmap(2) hints which would end up being in the hole to be accepted as valid,
causing unexpected signals when the process tries to access the hole
(since pmap can not fill the hole anyway).
Unfortunately, the logic mmap() uses to pick a valid address for anonymous
mappings needs work, as it will only try to find an address higher than the
hint, which causes all mmap() with a hint in the hole to fail on vax. This
will be improved later.

theoretical gain of it is close to zero, and our moms told us stealing is bad.

installation media now - it fits.
THIS MEANS YOU NEED TO RENAME /etc/hostname.de0 TO /etc/hostname.dc0

kernel builds locally this doesnt change much but over NFS this
cuts about 12% of the build time on my setup (i386).

cpu_disklabel can go away, since nothing anymore needs to use it; ok miod

cpu_disklabel's. 'labelsector' is not used anywhere according to grep.

more commonly encountered level 4. Do not complain in splassert() in this case
(this is similar to the older vsbus vax machines workaround).

to support hotplug media on most architectures. disklabel setup and
verification done using new helper functions. Disklabels must *always*
have a correct checksum now. Same code paths are used to learn on-disk
location disklabels, to avoid new errors sneaking in. Tested on almost all
cases, testing help from todd, kettenis, krw, otto, dlg, robert, gwk, drahn

correct and unify; ok thib miod

same thing. Keep LABELSECTOR and LABELOFFSET and nuke
ALPHA_LABELSECTOR and ALPHA_LABELOFFSET.
Kernel still compiles and boots.
Superfluidity pointed out by deraadt@.
|

routines (alpha, vax) prove to be not worth keeping. Move
bounds_check_with_label() into the MI world. Eliminate unreliable and
almost certainly useless checks for overwriting a disklabel.
After discussion with deraadt@
|
|
|
|
|
|
implimentations were simply either missing code, or spacing and such.
setdisklabel() can become MI now.
|

|

if enabled.

size which is the REAL DISK SIZE. always. if a driver fails to set
this right, please fix it. agreed with otto and krw
|

there.
'so go to it!' deraadt@

type of all variables to daddr64_t. this includes the APIs for XXsize()
and XXdump(), all range checks inside bio drivers, internal variables
for disklabel handling, and even uvm's swap offsets. re-read numerous
times by otto, miod, krw, thib to look for errors
|
|
accuracy so that the variious disksubr.c's can be compared easier.
setdisklabel() starts taking an int for openmask.
ok krw, and read by quite a few other people

to size. tested on almost all machines, double checked by miod and krw
next comes the type handling surrounding these values
|
|
convert version 0 to version 1 disklabels.
Suggested by deraadt@.

subsystems were enabled. others used a *md_diskconf -> diskconf() method to
make sure init_main could "do late setroot". Change all architectures to
have diskconf(), use it directly & late. tested by todd and myself on most
architectures, ok miod too
|
|
ok gwk, deraadt
|
|
bounds_check_with_label() routines as identical as possible without
changing any code. Code nits and adjustments to come.
|
|
|
|
bounds_check_with_label. All callers check for <= 0, so no functional
change.
Feedback from miod@.
ok weingart@

(and part of setroot); ok miod
|
|
This changes nothing on legacy architectures, but is a bit faster (and simpler)
on the interesting ones.
|
|
free room in struct partition by packing fragment size and
fragments/block more tighlty and use the resulting space to make
offset and size 48 bits. For the disk part we use spare fields in
struct disklabel. Kernel converts in-mem copy of the on-disk
label if needed, disklabel(8) writes new version.
We are careful to only change fields not used by bootloaders.
Conception of basic scheme by deraadt.

mbuf constants from MD param.h to MI param.h.
Besides being the same on every arch, things will
most probly break if any arch has different values
then the others.
The NMBCLUSTERS constants needs to be MD though;
