riscv timer: fix interrupt handling.
Based on the spec the STIP bit of SIP register is read-only.
To clear STIP bit from supervisor we have to do an SBI call to firmware.
Upon reception of SBI request, the machine-mode firmware clears the STIP
bit in the MIP register.
This fixes operation on Codasip A730.

riscv: Fix SSTC extension support
From the SSTC spec:
"If the stimecmp (supervisor-mode timer compare) register is implemented,
then STIP is read-only in mip and reflects the supervisor-level timer
interrupt signal resulting from stimecmp. This timer interrupt signal
is cleared by writing stimecmp with a value greater than the current time
value."
This fixes operation in Spike with sstc extension enabled.

spike --isa RV64IMAFDCH_zicntr_zihpm_sstc

share/man/man[49]: Set PACKAGE=kernel-man
When MANSPLITPKG is disabled (which is now the default), the kernel
manpages in sections 4 and 9 are installed in the -kernel package
instead of the -kernel-man package, because bsd.man.mk doesn't add
the -man suffix.
Since we already have handling for kernel-man in generate-ucl.lua,
set PACKAGE=kernel-man to make sure they're always in the right
package.
To avoid creating -kernel-man-man when WITH_MANSPLITPKG is enabled,
add some logic to bsd.man.mk (suggested by kevans) to avoid adding
the -man suffix if the package already has a -man suffix, and while
here, ensure ${__group}PACKAGE is always defined.

ifconfig: Enter jail as soon as possible
Some options (in particular, -g) are processed immediately upon being
parsed. This will produce the wrong result in combination with -j since
we only attach to the jail after we're done parsing arguments. Solve
this by attaching to the jail immediately when -j is encountered. The
downside is that e.g. `ifconfig -j foo -j bar` would previously attach
to jail “bar”, whereas now it will attempt to attach to jail “foo”, and
if successful, attempt to attach to jail “bar” within jail “foo”. This
may be considered a feature.

sound: Honor CHN_F_NBIO
If the device is opened with O_NONBLOCK, even though we check for it in
order to set CHN_F_NBIO, the subsequent chn_reset() calls will clear all
flags, except those set in CHN_F_RESET, which does not include
CHN_F_NBIO.
Add CHN_F_NBIO to CHN_F_RESET. Additionally, because primary channels
can be reused, make sure we do not unintentionally keep CHN_F_NBIO set
if the channel is re-opened, but without O_NONBLOCK.

jail: Optionally allow audit session state to be configured in a jail
Currently it is impossible for a privileged, jailed process to set audit
session state. This can result in suprising audit event misattribution.
For example, suppose a user ssh'es into a jail and restarts a service;
normally, sshd sets audit state such that events generated by the SSH
session are attributed to the newly authenticated user, but in a jail,
the corresponding setaudit(2) call fails, so events are attributed to
the user who had started sshd in the jail (typically the user who had
started the jail itself by some means).
While this behaviour is reasonable, administrators might want to trust
the jailed sshd to reset audit state, such that the authenticated user
appears in audit logs. Add a jail knob to enable this. Add a simple
regression test.

LinuxKPI: 802.11: avoid recursive wiphy lock
When freeing the last reference of the net80211 node the net80211
node_free() code may directly call into the crypto code to delete
the keys. While we still holding the wiphy lock this would lead to
a recursion on the non-recursive wiphy lock. Defer freeing the

LinuxKPI: pci: implement [linuxkpi_]pcim_request_all_regions()
Factor out the pci_request_region() implementation into an internal
function and make pci_request_region() a simple wrapperaround it.
Likewise implement pcim_request_all_regions() as a loop calling
pci_request_region() for each entry.
In two cases which we returned an error before (bar index is valid but
bar is not (no len), and neither IO nor MEM) we now reutrn success
(nothing to do for us). Otherwise callers, especially
pcim_request_all_regions() would error out for the wrong reasons.
This seems to also match the expected behaviour of pci_request_region().
