All variants of the 5714, 5715, and 5780 offer a feature called the
"Universal Management Port". This feature is implemented in firmware
and is largely transparent to the driver, except...
It turns out that the UMP firmware needs to know the current status
of the link. Because the firmware cannot touch the PHY registers while
the driver is in control of the device, it needs the driver to report
link status changes through an additional handshaking mechanism.
Without this handshake, it has been observed in the field that the UMP
firmware will not operate correctly.
This patch implements the new handshake with the UMP firmware. Since
the handshake uses the same mechanism ASF heartbeats use, code was
added to detect and wait for completion of a pending previous event.

A CPMU related loopback test bug existed for AX revisions of the 5761.
While that errata has been fixed, the CPMU still slows down the core
clock too far to run the loopback test successfully. This patch
disables the CPMU LINK_SPEED mode just like we do with the AX
revisions of the 5761 and all revisions of the 5784.

The MI clock is not configured correctly on adapters with the CPMU
present. The tg3 driver has code which statically sets the MI clock to
be a fraction of the speed at which the core clock is running.
However, the CPMU can change the adapter's core clock frequency based
on operating conditions. Consequently, the MI will run slow when the
core's clock has been slowed down.
There is a new 500KHz constant frequency clock available on adapters
with a CPMU. This patch removes the static core clock scaling and
configures the MI clock to use this new 500KHz clock instead.
Running the MI clock at slower speeds will not directly result in data
corruption, but it does challenge the PHY read and write routine timeouts.

WARN_ON_ONCE() gives a stack trace including the full module list.
Having this in the kernel dump for the timeout case in the

Force constants in kernel/timeconst.h (except shift counts) to be 64 bits,
using U64_C() constructor macros, and eliminate constants that cannot
be represented at all in 64 bits. This avoids warnings with some gcc
versions.
Drop generating 64-bit constants, since we have no real hope of
getting a full set (operation on 64-bit values requires a 128-bit
intermediate result, which gcc only supports on 64-bit platforms, and
only with libgcc support on some.) Note that the use of these
constants does not depend on if we are on a 32- or 64-bit architecture.
This resolves Bugzilla 10153.

Add C99-style constructor macros for fixed types to
<asm-generic/int-*.h>. Since Linux uses names like "u64" instead of
"uint64_t", the constructor macros are called U64_C() instead of
UINT64_C() and so forth.
These macros allow specific sizes to be specified as
U64_C(0x123456789abcdef), without gcc issuing warnings as it will if
one writes (u64)0x123456789abcdef.
When used from assembly, these macros pass their argument unchanged.
