ce3be286f0 Do not provide a hint of the guest's OS version
The calculation can overflow if __FreeBSD_version is big
enough, and it does not appear to be required.

fce9c39777 Fix the "am I a net80211 vap" check for bpf listeners.
I changed it to use if_transmit a while ago but apparently with monitor
mode the if_transmit method is overridden.

This is (mostly) a workaround until a more permanent solution can be
found.

bf5147c58b Sanitize the %eflags returned by BIOS routines. Some BIOS routines enter
protected mode and may leave protected-mode-specific flags like PSL_NT set
when they return to real mode.  This can cause a fault when BTX re-enters
protected mode after the BIOS mode returns.

59175f9f30 Fix for When more than one NIC is present.
The device name was incorrect due to a specific function we ported
from the Linux driver that is not FBSD compatible.  This resulted
with a false sysctl registration and some more problematic issues.

The patch basically revokes it all together.

acb9d2c7f0 The device vnodes are often unlocked when bread() or bwrite() is

context.

2c1531e746 Do not flush buffers when the v_object of the passed vnode does not
really belong to it. Such vnodes, with the pointers to other vnodes
v_objects, are typically instantiated by the bypass filesystems.
Invalidating mappings of other vnode pages and the pages is wrong,
since reclamation of the upper vnode does not imply that lower vnode
is reclaimed too.

One of the consequences of the improper reclamation was destruction of
the wired mappings of the lower vnode pages, triggering miscellaneous
assertions in the VM system.

1744fe5048 When growing the file descriptor table, new larger memory chunk is
allocated, but the old table is kept around to handle the case of
threads still performing unlocked accesses to it.

Grow the table exponentially instead of increasing its size by
sizeof(long) * 8 chunks when overflowing. This mode significantly
reduces the total memory use for the processes consuming large numbers
of the file descriptors which open them one by one.

6dfc67e379 Close the race on path ID allocation in xpt_bus_register() if two buses are
registered simultaneously. Due to topology unlock between the ID allocation
and the bus registration there is a chance that two buses may get the
same IDs. That is supposed reason of lock assertion panic in CAM during
initial bus scanning after new iscsid initiates two sessions same time.

4cfbfdd4b3 Add "better" MIPS24k and MIPS74k barriers.
* the mips74k cores only need EHB (which is 'sll $0, $0, 3')
  here; NOPs don't actually work.

* add EHB as the last NOP for the default barriers/hazards;
  that is "better" behaviour and should work on a wider
  variety of processors.

This allows the existing (icky) TLB code to work, allowing
the AR9344 SoC (mips74k) to actually get through kernel startup.

Tested:

* AR9344 SoC - (mips74k)
* AR9331 SoC - (mips24k)

TODO:

* test on mips4k CPUs, just to be sure.

* document that sll $0, $0, 3 is actually "EHB" and that it
  falls back to being a NOP for pre-mips32r1.

* mips24k has an errata that we currently don't correctly explicitly
  state - ie, that after DERET/ERET, the only valid instruction is
  a NOP.

57778cfec4 Add two new MIPS CPU families - mips24k and mips74k.
They're both different cores:

* mips24k is an 8-stage pipeline, mips32r1 ABI, non-superscalar core.
* mips74k is a dual-issue 15-stage superscalar design, mips32r2 ABI.

They have different sets of quirks and bugs; these #define entries
will be used to work around these.

Now, strictly speaking, we should have CPU ABI families (mips32r1, mips32r2,
etc) and CPU core types (mips4k, mips24k, mips74k, etc.)  But this is the
starting point of that particular tidy-up.
