tg3: Fix ethtool loopback test for 5761 BX devices
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.

tg3: Use constant 500KHz MI clock on adapters with a CPMU
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.

Make constants in kernel/timeconst.h fixed 64 bits
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.

neither interrupts nor polling should be enabled during a root-hub

polling isn't needed.
Furthermore the EGSM (Enter Global Suspend Mode) bit shouldn't be set

[SCSI] Let scsi_cmnd->cmnd use request->cmd buffer
- struct scsi_cmnd had a 16 bytes command buffer of its own.
This is an unnecessary duplication and copy of request's
cmd. It is probably left overs from the time that scsi_cmnd
could function without a request attached. So clean that up.
- Once above is done, few places, apart from scsi-ml, needed
adjustments due to changing the data type of scsi_cmnd->cmnd.
- Lots of drivers still use MAX_COMMAND_SIZE. So I have left
that #define but equate it to BLK_MAX_CDB. The way I see it
and is reflected in the patch below is.
MAX_COMMAND_SIZE - means: The longest fixed-length (*) SCSI CDB
as per the SCSI standard and is not related
to the implementation.
BLK_MAX_CDB. - The allocated space at the request level
- I have audit all ISA drivers and made sure none use ->cmnd in a DMA
Operation. Same audit was done by Andi Kleen.
(*)fixed-length here means commands that their size can be determined
by their opcode and the CDB does not carry a length specifier, (unlike
the VARIABLE_LENGTH_CMD(0x7f) command). This is actually not exactly
true and the SCSI standard also defines extended commands and
vendor specific commands that can be bigger than 16 bytes. The kernel
will support these using the same infrastructure used for VARLEN CDB's.
So in effect MAX_COMMAND_SIZE means the maximum size command
scsi-ml supports without specifying a cmd_len by ULD's

The PROM library function prom_meminit() builds a table,

sparc32: Kill totally unused memory information tables.
The code in arch/sparc/prom/memory.c computes three tables, the list
of total memory, the list of available memory (total minus what
firmware is using), and the list of firmware taken memory.
Only the available memory list is even used.
Therefore, kill those unused tables and make prom_meminfo() return
just the available memory list.

sparc64: Fix syscall restart, for real...
The change I put into copy_thread() just papered over the real
problem.
When we are looking to see if we should do a syscall restart, when
deliverying a signal, we should only interpret the syscall return
value as an error if the carry condition code(s) are set.
Otherwise it's a success return.
Also, sigreturn paths should do a pt_regs_clear_trap_type().
It turns out that doing a syscall restart when returning from a fork()
does and should happen, from time to time. Even if copy_thread()
returns success, copy_process() can still unwind and signal
-ERESTARTNOINTR in the parent.
