Note that -525703168 (an int) is 0xe0aa6800 in binary representation.
The partition indexes are actually stored as uint8_t, so that value
was converted / truncated to zero.

Work around llvm 11 miscompile in 32 bit powerpc that appears to cause ifuncs
to branch to the wrong address by forcing -O2. This worked in previous
versions because -O was mapped to -O2 previously (but is now -O1.)
While here, remove the old temporary workaround from r224882 that does the
opposite thing for powerpc non-DEBUG kernels, bringing it in line with other
platforms that compile at -O2.
This fixes kernel boot on powerpc and powerpcspe after the llvm11 transition.

We have some hacks to remove stale dependency files for NO_CLEAN

intended to upport ongoing NO_CLEAN builds, and are no longer needed
after a sufficient amount of time elapses.
orig_object->type can change from OBJT_DEFAULT to OBJT_SWAP while
vm_object_split() is sleeping. In this case some pages in new_object
may be left unbusied, but vm_object_split() attempts to unbusy all of
them.
Track the beginning of the busied range. Add an assertion to verify
that pages are not re-added to the source object while sleeping.

In order to enable VDSO timekeeping, it is necessary that there be exactly
one primary FreeBSD sysvec for each of the host and (optionally) compat32.
So, switch ELFv1 to being a secondary sysvec of ELFv2, so it does not get
double-allocated in the shared page.
Since secondary sysvecs use the same sigcode allocation as the primary,
define both to use the main sigcode64, and adjust the sv_sigcode_base on
ELFv2 after initialization to point to the correct offset.
This has the desirable side effect of avoiding having a separate copy of
the signal trampoline in the shared page. Our sigcode64 was already written
to take advantage of trampoline sharing, it was just not being allocated
that way until now.

Since x86 is the only 32-bit arch that has a 32-bit time_t, adjust the
private bintime32 struct in vdso to only use a 32 bit sec on amd64.
This matches the existing behavior in the compat code.
Noticed while implementing vdso timekeeping on powerpc.
This should also theoretically fix vdso timekeeping for arm binaries on
aarch64.

ENETRESET but only 0 or error.
As ieee80211(9) tells the ieee80211_media_change() function should not
be called directly but is registered with ieee80211_vap_attach() instead.
Some drivers have not been fully converted. After fixing the return
checking some of these functions were simply wrappers between
ieee80211_vap_attach() and ieee80211_media_change(), so remove the extra

At least on Orange Pi PC Plus even the host mode does not work without
enabling the phy and setting it to the host mode.
The driver will now parse dr_mode property and will try to configure
itself and the phy accordingly.
OTG mode is not supported yet, so it is treated as the device / peripheral
mode.
The phy is enabled -- powered on -- only for the host mode.
The device mode requires support from a phy driver, e.g., aw_usbphy on
Allwinner platform.
aw_usbphy does not support the device mode, so it cannnot work yet.

When cache precedes files, and nscd is configured to allow negative caching,
commands like "pw groupadd" can fail. The sequence of events looks like:
1. A command like pkg(8) looks up the group, and finds it absent.
2. pkg invokes pw(8) to add the group
3. pkg queries the group, but nscd says it doesn't exist, since it has a
negative cache entry for that group.

For historical reasons, defining MALLOC_PRODUCTION in /etc/make.conf has
been used to turn off potentially expensive debug checks and statistics
gathering in the implementation of malloc(3).
It seems more consistent to turn this into a regular src.conf(5) option,
e.g. WITH_MALLOC_PRODUCTION / WITHOUT_MALLOC_PRODUCTION. This can then
be toggled similar to any other source build option, and turned on or
off by default for e.g. stable branches.

For the TLS case where there is a "user@domain" name specified in the
X.509 v3 certificate presented by the client in the otherName component
of subjectAltName, a gid list is allocated via mem_alloc().
This needs to be free'd. Otherwise xp_gidp == NULL and free() handles that.
(The size argument to mem_free() is not used by FreeBSD, so it can be 0.)
This leak would not have occurred for any other case than NFS over TLS
with the "user@domain" in the client's certificate.
