4e7e2cad09 Remove unportable calls to basename().
The POSIX version of basename() doesn't use a 'const char *' argument;
the function may overwrite its input buffer. Instead of copying the
input string, let's just simplify this code by using our getprogname()
function that already returns the name of the application in the right
format.

328d8adb9b Allow DOF sections with excessively long probe function components.
Without this change, DTrace will refuse to load a DOF section if the
function component of any of its probes exceeds DTRACE_FUNCNAMELEN (128).
Probes in C++ programs can have very long function components. Rather than
rejecting all probes if a single probe exceeds the limit, simply skip the
invalid probe and emit a warning. This ensures that valid probes are
instantiated.

52a510ace9 Encapsulate SYSV IPC objects in jails. Define per-module parameters
sysvmsg, sysvsem, and sysvshm, with the following bahavior:

inherit: allow full access to the IPC primitives.  This is the same as
the current setup with allow.sysvipc is on.  Jails and the base system
can see (and moduly) each other's objects, which is generally considered
a bad thing (though may be useful in some circumstances).

disable: all no access, same as the current setup with allow.sysvipc off.

new: A jail may see use the IPC objects that it has created.  It also
gets its own IPC key namespace, so different jails may have their own
objects using the same key value.  The parent jail (or base system) can
see the jail's IPC objects, but not its keys.

8a3fcfa7be [bhnd] Fix ChipCommon probing.
ChipCommon probing uses mapping table "chipc_devices". It calls bhnd_device_lookup,
which iterate over mapping table with end condition:

entry->desc != NULL

So if mapping table contains row with description equals to NULL, it will
stop processing of mapping. I.e. description is mandatory field and should
be not NULL.

This patch corrects mapping table for ChipCommon.

8d170e6ac1 [iwn] fix firmware command use in iwm_auth().
The iwm firmware has separate commands for add, modify and delete for
various things (mac, phy context, etc.)  The openbsd driver has a habit
of just completely resetting the NIC each time, which is technically
mostly okay (as long as the reset doesn't actually fail!) but it means
a lot of the code is doing ADD when it should do MODIFY.

The firmware responds in kind - it just asserts.

This fixes auth attempts that occur after the NIC has been already
configured.

(I'm sure there are more instances of this!)

Tested:

iwm0: <Intel Dual Band Wireless AC 7260> mem 0xf1400000-0xf1401fff irq 17 at device 0.0 on pci2

02a371289a o Implement shared pagetables and switch from 4 to 3 levels page
memory system.

RISC-V ISA has only single page table base register for both kernel
and user addresses translation. Before this commit we were using an
extra (4th) level of pagetables for switching between kernel and user
pagetables, but then realized FPGA hardware has 3-level page system
hardcoded. It is also become clear that the bitfile synthesized for
4-level system is untested/broken, so we can't use extra level for
switching.

We are now share level 1 of pagetables between kernel and user VA.
This requires to keep track of all the user pmaps created and once we
adding L1 page to kernel pmap we have to add it to all the user pmaps.

o Change the VM layout as we must have topmost bit to be 1 in the
  selected page system for kernel addresses and 0 for user addresses.
o Implement pmap_kenter_device().
o Create the l3 tables for the early devmap.

21e2c118b8 Do not setup machine exception vector.
Sounds strange, but both RocketCore and lowRISC do not operate
if we set it.

All the known implementations (Spike, QEMU, RocketCore, lowRISC) uses
default machine trap vector address and operates fine with this.

Original Berkeley Boot Loader (bbl) does not set this as well.

There is no need to clear all the DDR memory (we only need to clear
BSS section).
I was playing with non-default version of hardware (the bitfile
synthesized for 4-level page memory system) and clearing was helpful,
but then realized support for 4-level page system is untested/broken
in both RocketCore and lowRISC.
