# If we behaved like book publishers, we'd do this in July. I can't find
# a good reference for why they do it then, but it has been explained to

- provide an interface (macros) to the page coloring part of the VM system,
this allows to try different coloring algorithms without the need to
touch every file [1]
- make the page queue tuning values readable: sysctl vm.stats.pagequeue
- autotuning of the page coloring values based upon the cache size instead
of options in the kernel config (disabling of the page coloring as a
kernel option is still possible)
MD changes:
- detection of the cache size: only IA32 and AMD64 (untested) contains
cache size detection code, every other arch just comes with a dummy
function (this results in the use of default values like it was the
case without the autotuning of the page coloring)
- print some more info on Intel CPU's (like we do on AMD and Transmeta
CPU's)
Note to AMD owners (IA32 and AMD64): please run "sysctl vm.stats.pagequeue"
and report if the cache* values are zero (= bug in the cache detection code)
or not.

security.mac.biba.interfaces_equal
If non-zero, all network interfaces be created with the label:
biba/equal(equal-equal)
This is useful where programs which initialize network interfaces
do not have any labeling support. This includes dhclient and ppp. A
long term solution is to add labeling support into dhclient(8)
and ppp(8), and remove this variable.
It should be noted that this behavior is different then setting the:
security.mac.biba.trust_all_interfaces
sysctl variable, as this will create interfaces with a biba/high label.
Lower integrity processes are not able to write to the interface in this
event. The security.mac.biba.interfaces_equal will override
trust_all_interfaces.
The security.mac.biba.interfaces_equal variable will be set to zero
or disabled by default.

force allocation of unallocated BARs (cardbus uses this to preallocate
everything). Add a prefetchmask to allow for busses that get prefetch
hints to set them. Addjust pci_add_map and pci_ata_maps to take a new
force flag which pci_add_resources will pass in. Implement 'force' in
pci_add_map. Write new value of allocated resource into the bar, if
the allocation succeeded (we should have done this before, but with
the new force the bug was very obvious).
- Provide tunable vm.memguard.desc, so one can specify memory type without
changing the code and recompiling the kernel.
- Allow to use memguard for kernel modules by providing sysctl
vm.memguard.desc, which can be changed to short description of memory
type before module is loaded.
- Move as much memguard code as possible to memguard.c.
- Add sysctl node vm.memguard. and move memguard-specific sysctl there.
- Add malloc_desc2type() function for finding memory type based on its
short description (ks_shortdesc field).
- Memory type can be changed (via vm.memguard.desc sysctl) only if it
doesn't exist (will be loaded later) or when no memory is allocated yet.
If there is allocated memory for the given memory type, return EBUSY.
- Implement two ways of memory types comparsion and make safer/slower the
default.
This should reduce huge playback / recording latency for
applications that try to act smarter and manage their own
buffering (XMMS, Skype, etc.).
Note to Skype + via8xxx users: Remove previous hackish
"hint.pcm.<unit>.via_dxs_disabled" from kernel hint and see
whether this changes cure all those annoying sound issues.

try very hard to be perfect. However, these attempts broke down when
there were large numbers of resources. We'd not be able to map them all.
Instead, accept that we might pass more range to thse subbus than
might be optimal be able to compute. However, there's little harm in
this and it allows us to pass greater resources through.
# it has been suggested that we allocate a fixed amount of resources
# on attach and give it out upon request. This might not be a bad idea...
The race is very real, but conditions needed for triggering it are rather
hard to meet now.
When gjournal will be committed (where it is quite easy to trigger) we need
to fix it.
For now, verify if it is really hard to trigger.
