While the return code is broken, some corner case usage depends on the
functionnality, so backout until we get better regression tests covering those
corner case usage.
In order for drivers to provide an alternate set of scan methods,
these have to finally use an indirection table and all of the calls
in ieee80211_scan.c need to use said table.
For all existing drivers - this is basically a glorified, KBI-breaking
functional no-op.
This is also not the final form - too much functionality is currently
hiding in ieee80211_scan_sw.c that should be in ieee80211_scan.c.
That'll be the target of some follow-up commits.
Note:
* You have to recompile your kernel/drivers after this - the net80211 KBI has
changed.
* I'm not yet planning on bumping any versioning - I have a few more things
to shuffle around.
Tested:
* urtwn(4) - STA mode
* Intel 7260 in local repo - overriding the methods and table at
attach time has the desired effect (ie, all the methods are called,
but nothing is ever performed.)
the intent of -q in this command is to return as exit status the value of the
next group/user id, which does not make sense given exit status are limited to
values between 0 and 255.
Lock order checking is done without the witness mutex held, so multiple
threads that are racing to establish a new lock order may read matrix
entries that are in an inconsistent state. Don't print a warning in this
case, but instead just redo the check after taking the witness lock.

From Thomas Eriksson
Adjust API to a more modern readline (Ryo Onodera)
remove duplicate declaration
Currently there is no good reason to mangle the userland API.
The change was introduced in eac1d566b46edef765754203bef22c75c1699966,
r279437. Also see https://reviews.freebsd.org/D1881.
I am still convinced that nv should not have introduced intentionally
conflicting API.

This is also implemented in at least GNU coreutils cp.
While here also improve the '-l' handling to not open(2) the source file as
it does not actually need the descriptor.

rev. 55. The modern CPUs cache and TLB descriptions looked quite
questionable without the update, e.g. Haswell i7 4770S reported:
Data TLB: 4 KB pages, 4-way set associative, 64 entries
L2 cache: 256 kbytes, 8-way associative, 64 bytes/line
After the update, the report is:
Data TLB: 1 GByte pages, 4-way set associative, 4 entries
Data TLB: 4 KB pages, 4-way set associative, 64 entries
Instruction TLB: 2M/4M pages, fully associative, 8 entries
Instruction TLB: 4KByte pages, 8-way set associative, 64 entries
64-Byte prefetching
Shared 2nd-Level TLB: 4 KByte/2MByte pages, 8-way associative, 1024 entries
L2 cache: 256 kbytes, 8-way associative, 64 bytes/line
Some tags were apparently removed from the table 3-21, Vol. 2A. Keep
them around, but add a comment stating the removal.
Update the format line for cpu_stdext_feature according to the bits
from the SDM rev.55. It appears that Haswells do not store %cs and
%ds values in the FPU save area.
Store content of the %ecx register from the CPUID leaf 0x7
subleaf 0 as cpu_stdext_feature2 and print defined bits from it,
again acording to SDM rev. 55.

before adjusting it to store any registers. This is needed as DTrace may
need to adjust the kernel stack pointer, and previously the new stack
pointer would have needed to be checked incase it was changed.
return -1000 and -10000 to establish a pecking order and we don't want
catch-all or match-all drivers to attach instead of them.
With this change poto(4) can be compiled into the kernel (or preloaded
from the loader), without impact.
(easily) without having to go to other drivers to change the
magical return values. This wouldn't be so bad if there were
proper defines for these constants.
In particular dev/acpica/acpi_pcib_pci.c returns -1000 as the
probe priority and it's expected that this driver gets to
attach over the common PCI bus drivers.
The "depends_on module" pragma can be used to declare a dependency on a
DTrace module, which for kernel probes corresponds to a KLD. Such
dependencies cannot be checked if the KLD is compiled into the kernel.
Therefore, allow a module dependency to be satisfied if either a kernel
module or a KLD with the specified name is loaded.
