Without this patch we were not able to see the assembly function.
Only the function descriptor was visible.
- Distinguish between user-land and kernel when creating the ENTRY() point of
assembly source.
- Make the ENTRY() macro more readable, replace the .align directive with the
gas platform independant .p2align directive.
- Create an END()macro for later use to provide traceback tables on powerpc64.
These fans are not located under the same node as the the RPM controlled ones,
So I had to adapt the current source to parse and fill the properties correctly.
To control the fans we can set the PWM ratio via sysctl between 20 and 100%.

* Change in mesh_input to validate that QoS is set and Mesh Control field
is present, also both bytes of the QoS are read;
* Moved defragmentation in mesh_input before we try to forward packet as
inferred from amendment spec, because Mesh Control field only present in first
fragment;
* Changed in ieee80211_encap to set QoS subtype and Mesh Control field present,
only first fragment have Mesh Control field present bit equal to 1;

* Moved old categories as specified by D4.0 to be action fields of MESH category
as specified in amendment spec;
* Modified functions to use MESH category and its action fields:
+ ieee80211_send_action_register
+ ieee80211_send_action
+ ieee80211_recv_action_register
+ieee80211_recv_action;
* Modified ieee80211_hwmp_init and hwmp_send_action so they uses correct
action fields as specified in amendment spec;
* Modified ieee80211_parse_action so that it verifies MESH frames.
* Change Mesh Link Metric to use one information element as amendment spec.
Draft 4.0 defined two different information elements for request and response.

It may be worth getting rid of some of the ifdefs and introducing gratuitous
SV_ILP32 runtime checks on n64 kernels without COMPAT_FREEBSD32 and on o32
kernels, similarly to how PowerPC works.
that it is better to error out when people attempt to build using the
wrong bsd.*.mk files, than to silently ignore the problem.
This means, that after this commit, if you want to build kernel modules
by hand (or via a port) from a head source tree, you *must* make sure
the files in /usr/share/mk are in sync with that tree. If that isn't
possible, for example when you are running on an older FreeBSD branch,
you can:
- Run "make buildenv" from your head source tree, to have the correct
environment setup. (It's advisable to have run "make buildworld", or
at a minimum "make toolchain" first.)
- Alternatively, set MAKESYSPATH to the share/mk directory under your
head source tree. If your build tools are too old, other problems may
still occur.
- Alternatively, use "make -m" and specify the share/mk directory under
your head source tree. Again, build tools that are too old may still
result in trouble.

This fixes sendmsg under COMPAT_FREEBSD32 on n64 MIPS kernels.
kernel modules using their old installed /usr/share/mk/bsd.*.mk files,
instead of the updated ones in their source tree. This leads to errors
like:
"sys/conf/kmod.mk", line 111: Malformed conditional (${MK_CLANG_IS_CC} == "no" && ${CC:T:Mclang} != "clang")
Obviously, these errors will go away after a "make installworld", or
alternatively, by using "make buildenv" before attempting to manually
build modules.
However, since it is apparently an expected use case to build using old
.mk files, change the way we test for clang, so it also works when the
MK_CLANG_IS_CC macro doesn't exist.
Note the conditional expressions are becoming rather unreadable now, but
I will attempt to fix that on a followup commit.

- pci_find_extcap() is repurposed to be used for fetching PCI-express
extended capabilities (PCIZ_* constants in <dev/pci/pcireg.h>).
- pci_find_htcap() can be used to locate a specific HyperTransport
capability (PCIM_HTCAP_* constants in <dev/pci/pcireg.h>).
- Cache the starting location of the PCI-express capability for PCI-express
devices in PCI device ivars.
in the new NFS server for NFSv4, where it would report ENOENT
when the file actually existed on the server. This turned out
to be caused by not initializing ni_topdir before calling lookup()
and there was a rare case where the value on the stack location
assigned to ni_topdir happened to be a pointer to a ".." entry,
such that "dp == ndp->ni_topdir" succeeded in lookup().
This patch initializes ni_topdir to fix the problem.

message signaled interrupts.
- Discourage use of pci_disable_io() and pci_enable_io() in device drivers.

using the o32 ABI. This mostly follows nwhitehorn's lead in implementing
COMPAT_FREEBSD32 on powerpc64.
o) Add a new type to the freebsd32 compat layer, time32_t, which is time_t in the
32-bit ABI being used. Since the MIPS port is relatively-new, even the 32-bit
ABIs use a 64-bit time_t.
o) Because time{spec,val}32 has the same size and layout as time{spec,val} on MIPS
with 32-bit compatibility, then, disable some code which assumes otherwise
wrongly when built for MIPS. A more general macro to check in this case would
seem like a good idea eventually. If someone adds support for using n32
userland with n64 kernels on MIPS, then they will have to add a variety of
flags related to each piece of the ABI that can vary. That's probably the
right time to generalize further.
o) Add MIPS to the list of architectures which use PAD64_REQUIRED in the
freebsd32 compat code. Probably this should be generalized at some point.

significantly. Upon investigation this was caused by name cache
misses for lookups of "..". For name cache entries for non-".."
directories, the cache entry serves double duty. It maps both the
named directory plus ".." for the parent of the directory. As such,
two ctime values (one for each of the directory and its parent) need
to be saved in the name cache entry.
This patch adds an entry for ctime of the parent directory to the
name cache. It also adds an additional uma zone for large entries
with this time value, in order to minimize memory wastage.
As well, it fixes a couple of cases where the mtime of the parent
directory was being saved instead of ctime for positive name cache
entries. With this patch, Lookup RPC counts return to values similar
to pre-r230394 kernels.
