Add per-port vlan support for the AR8327.
All the per-port support is really doing is applying a port visibility
mask to each of the switchports. Everything still look like a single
portgroup (vlan id 1), but the per-port visibility mask is modified.
Whilst I'm here, also add some initial dot1q support - the pvid stuff
is doing the right thing, but it's not useful without the rest of
the VLAN table programming.
It's enough for me to be able to use the LAN/WAN port distinction
on the AP135, where there isn't (for now!) a dedicated PHY for the
"WAN" port.

Save and restore non-volatile floating-point registers during longjmp().
This should also save and restore non-volatile Altivec registers, but that
needs to wait on solving two problems:
1. Adding the nonvolatile vector registers means we need 5 more than _JBLEN
entries in jmp_buf on 32-bit targets (64-bit is OK).
2. Need to figure out how to determine if saving/restoring vector regs
is supported on the current CPU from userland.

Add support for enabling the USB on the Raspberry Pi boards when it hasn't
been done by U-Boot. This allows the USB to work when we load the kernel
directly.
No dma sync is performed after these operations as the data we read/write
is not used by the cpu after the calls to the maimbox driver.

Fix up support for the AR8327.
* Even though I got the registers around "right", it seems
I'm not tickling the MDIO access correctly for the internal PHY
bus. Some of the switches are fine poking at the external PHY
registers; others aren't. So, enable direct PHY bus access
for the AR8327, and leave the existing code in place for the
others.
* Go and shuffle the register access around. Whilst here,
restore the 2ms delay if changing page.

Changes affecting future time stamps
The Mexican state of Quintana Roo, represented by America/Cancun,
will shift from Central Time with DST to Eastern Time without DST
on 2015-02-01 at 02:00. (Thanks to Steffen Thorsen and Gwillim Law.)
Chile will not change clocks in April or thereafter; its new standard time
will be its old daylight saving time. This affects America/Santiago,
Pacific/Easter, and Antarctica/Palmer. (Thanks to Juan Correa.)
New leap second 2015-06-30 23:59:60 UTC as per IERS Bulletin C 49.
(Thanks to Tim Parenti.)
Changes affecting past time stamps
Iceland observed DST in 1919 and 1921, and its 1939 fallback
transition was Oct. 29, not Nov. 29. Remove incorrect data from
Shanks about time in Iceland between 1837 and 1908.
Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: Asia/Aden, Asia/Bahrain, Asia/Kuwait,
and Asia/Muscat.

Add the MD parts of dtrace needed to use fbt on ARM. For this we need to
emulate the instructions used in function entry and exit.
For function entry ARM will use a push instruction to push up to 16
registers to the stack. While we don't expect all 16 to be used we need to
handle any combination the compiler may generate, even if it doesn't make
sense (e.g. pushing the program counter).
On function return we will either have a pop or branch instruction. The
former is similar to the push instruction, but with care to make sure we
update the stack pointer and program counter correctly in the cases they
are either in the list of registers or not. For branch we need to take the
24-bit offset, sign-extend it, and add that number of 4-byte words to the
program counter. Care needs to be taken as, due to historical reasons, the
address the branch is relative to is not the current instruction, but 8
bytes later.
This allows us to use the following probes on ARM boards:
dtrace -n 'fbt::malloc:entry { stack() }'
and
dtrace -n 'fbt::free:return { stack() }'
