49dae58b28 Fix including Kyuafile in packaged base system.
Fix a related typo while here.

Note, this change results in the Kyuafile inclusion in the runtime
package, which needs to be fixed, however addresses the PR as far
as I can tell in my tests.

ce725c8e00 [ath] Add LDPC transmit support.
LDPC adds better transmit reliability if both ends support it.

You in theory can do both STBC and LDPC at the same time.
If I see issues I'll disable it.

* Only enable it if both ends of a connection negotiate it.
* Disable it if any rate is non-11n.
* Count both LDPC TX and STBC TX.

Tested:

* AR9380, STA mode

9b40530293 [net80211] handle action frames in adhoc mode from the node that created the BSS.
We don't have a separate bss node; instead we dup the first node we saw
and turn that into the BSS node.  This means that action frames from
that node would be rejected.

So, check that the node is the bss node /and/ the MAC doesn't match ni_macaddr.
That's the "right" way for now to verify it's an unknown node.

This fixes handling action frames in adhoc mode, which includes negotiating
11n aggregation via ADDBA/DELBA.

This by itself isn't enough to correctly create 11n adhoc networks; but
it is required for aggregation to be negotiated.

Tested:

* AR9380, 11n adhoc mode
* broadcom 11ac adhoc (vendor platform)

bdb02ec712 ARM: Use kernel pmap as intermediate mapping in context switch.
On ARM, we can directly switch between translation tables only when
the size of the mapping for any given virtual address is the same in
the old and new translation tables. The load of new TTB and subsequent
TLB flush is not atomic operation. So speculative page table walk can
load TLB entry from new mapping while rest of TLB entries are still the
old ones. In worst case, this can lead to situation when TLB cache can
contain multiple matching TLB entries. One (from old mapping) L2 entry
for VA + 4k and one (from new mapping) L1 entry for VA.

Thus, we must switch to kernel pmap translation table as intermediate
mapping because all sizes of these (old pmap and kernel pmap) mappings
are same (or unmapped). The same is true for switch from kernel pmap
translation table to new pmap one.

e5e4452078 ensure that initial local apic id is sane on AMD 10h systems
Summary:
The Initial Local APIC ID is returned by CPUID function 1 (in EBX).
On AMD Family 10h systems the way that ID is built is controlled by
an MSR bit (InitApicIdCpuIdLo).  BKDG instructs BIOS to set it in a
certain way, but a BIOS can be buggy.  In that case the ID can confuse
tools that use it, e.g. hwloc.
For example, on a system that I own real Local APIC IDs are configured
as 0, 1, 2, 3, but IDs reported via CPUID.1 are 0, 0x40, 0x80, 0xc0.

acpi_pcib_attach().  Instead, acpi_pcib_attach() is renamed to
acpi_pcib_fetch_prt() as it's sole action now is to fetch the PCI

88eb5c506d Add 'devctl delete' that calls device_delete_child().
'devctl delete' can be used to delete a device that is no longer present.
As an anti-foot-shooting measure, 'delete' will not delete a device
unless it's parent bus says it is no longer present.  This can be
overridden by passing the force ('-f') flag.

Note that this command should be used with care.  If a device is deleted
that is actually present it can't be resurrected unless the parent bus
device's driver supports rescans.

3d0338a092 Implement a PCI bus rescan method.
Rescanning a PCI bus uses the following steps:
- Fetch the current set of child devices and save it in the 'devlist'
  array.
- Allocate a parallel array 'unchanged' initalized with NULL pointers.
- Scan the bus checking each slot (and each function on slots with a
  multifunction device).
- If a valid function is found, look for a matching device in the 'devlist'
  array.  If a device is found, save the pointer in the 'unchanged' array.
  If a device is not found, add a new device.
- After the scan has finished, walk the 'devlist' array deleting any
  devices that do not have a matching pointer in the 'unchanged' array.
- Finally, fetch an updated set of child devices and explicitly attach any
  devices that are not present in the 'unchanged' array.

This builds on the previous changes to move subclass data management into
pci_alloc_devinfo(), pci_child_added(), and bus_child_deleted().

Subclasses of the PCI bus use custom rescan logic explicitly override the
rescan method to disable rescans.
