# this should allow us to move kern.post.mk to the last line of the makefiles,

Any modifications to SYSTEM_OBJS after including kern.post.mk
will not make it to SYSTEM_DEP and consequently any dependency
rules. This caused __{div|rem}* to not be built...
It doesn't help us catch overflowing vector entries at compile time.
Instead use the .org directive. The last entry in the IVT doesn't
strictly need to be limited to 256 bytes, but doing so allows the
the VHPT to be placed immediately following the IVT without wasting
any space due to alignment.
as being valid. Previously only the magic number and the virtual
address were checked, but it makes little sense to require that
the virtual address is the same (the message buffer is located at
the end of physical memory), and checks on the msg_bufx and msg_bufr
indices were missing.

* Re-organise RID allocation so that we don't accidentally give a RID
to two different processes. Also randomise the order to try to reduce
collisions in VHPT and TLB. Don't allocate RIDs for regions which are
unused.
* Allocate space for VHPT based on the size of physical memory. More
tuning is needed here.
* Add sysctl instrumentation for VHPT - see sysctl vm.stats.vhpt
* Fix a bug in pmap_prefault() which prevented it from actually adding
pages to the pmap.
* Remove ancient dead debugging code.
* Add DDB commands for examining translation registers and region
registers.
The first change fixes the 'free/cache page %p was dirty' panic which I
have been seeing when the system is put under moderate load. It also
fixes the negative RSS values in ps which have been confusing me for a
while.
With this set of changes the ia64 port is reliable enough to build its
own kernels, even with a 20-way parallel build. Next stop buildworld.
o Bite the bullet and create controller types for the 6729 and also for
the 673x. Rename the 672x to 6722.
o Define minimal extended register info (just register 0xa for reading VS[12]).
# I think the last version may have broken 673x controllers, but this should
# fix them.
Tested on the 6722, but not the 6729.

on my CL-PD6722, but won't work on the CL-PD6729. The latter two need
more sophisticated detection of 3.3V cards than I'm up to at the
moment. Also, only a few of the ISA chipsets that support 3.3V will
likely work at the moment.
It appears that for 3.3V cards we must detect them and adjust the
pwr.vcc value from 50 to 33. Give a strong hint to automatically
power up the card for PD_POWER cards.
This makes my SMC 2602W (the 3.3V version of the 2632W) work on my
Fujitsu Stylistic 500.

Basically FIFOs become a real pain to abuse as a rendevous point without
this change because you can't really select(2) on them because they always
return ready even though there is no writer (to signal EOF).

sysctl handlers to have access to the current thread, permitting work
on implementing td->td_ucred, migration of suser() to using struct
thread to derive the appropriate ucred, and allowing struct thread to be
passed down to other code, such as network code where td is not currently
available (and curproc is used).
o Note: netncp and netsmb are not updated to reflect this change, as they

When there is no suitable inbound policy for the packet of the ipsec
tunnel mode, the kernel never decapsulate the tunneled packet
as the ipsec tunnel mode even when the system wide policy is "none".
Then the kernel leaves the generic tunnel module to process this
packet. If there is no rule of the generic tunnel, the packet
is rejected and the statistics will be counted up.
