The current implementation of __pa() for 64-bits kernels with 32-bits
symbols is broken. In this configuration, we need 2 values for
PAGE_OFFSET, one in XKPHYS and the other in CKSEG0 space.
When the value in CKSEG0 space is used, it doesn't take into account
of PHYS_OFFSET. Even worse we can't redefine this value.
The patch restores CPHYSADDR() but in __pa()'s implementation because
it removes the need of 2 PAGE_OFFSET.
OTOH, CPHYSADDR() is quite bad when dealing with mapped kernels. So
this patch assumes there's no need to deal with such kernel in 64-bits
world.

For platforms that use PHYS_OFFSET and do not use a mapped kernel,
this patch automatically adds PHYS_OFFSET into PAGE_OFFSET.
Therefore there are no more needs for them to redefine PAGE_OFFSET.
For mapped kernel, they need to redefine PAGE_OFFSET anyways.

PAGE_OFFSET definition is now using CAC_BASE by default.
This patch also reorder some macros to make them appear
in the same order for both 32 and 64 bits configs.
It also makes use of const.h generic header file to
annotate constants.

Before this patch, when a platform needed to customize one constant in
spaces.h, they need to redefine all of them.
Now they can just redefine one constant and include the generic file
header at the end:
#include <asm/mach-generic/spaces.h>
This patch doesn't allow to redefine CAC_BASE, IO_BASE and UNCAC_BASE
for 32 bits platforms because there's no need to do so.
This will avoid some macro duplications. It's important specially if
we'll add complex macros.

No point in adding yet another #ifdef for Loongson since all this mask is
being used for is converting an XKPHYS address into a physical address
anyway. So replace all definitions by one with the highest architectural
possible value.

The 82550 & 51 parts have an extended configuration block that
includes a bit "GMRC", required to enable the expected TCO behavior,
in config byte offset 22d. The config block sent by the failing driver
does include the extension area, but this bit is not initialised,
and the downlaod only specifies 0x16 bytes to be sent to the NIC
(thaht's bytes 00..21d). By initializing the GMRC bit, and extending
the download size for D102+ MACs, the problem is resolved.

We intend this patch to improve spidernet interrupt handling to be
more strict. We had following problem and this patch solves it.
-when CONFIG_DEBUG_SHIRQ=y, request_irq() calls handler().
-when spider_net_open() is called, it calls request_irq() which calls
spider_net_interrupt().
-if some specific interrupt bit is set at this timing, it calls
netif_rx_schedule() and spider_net_poll() is scheduled.
-spider_net_open() calls netif_poll_enable() which clears the bit
__LINK_STATE_RX_SCHED.
-when spider_net_poll() is called, it calls netif_rx_complete() which
causes BUG_ON() because __LINK_STATE_RX_SCHED is not set.

The 3cSOHO100-TX needs a mdio_sync() before mdio_read() to read the MII
transceiver registers properly. Adding EXTRA_PREAMBLE to drv_flags of the
3cSOHO100-TX will force this.
This problem exists already for years (I checked back to 2.6.8).
Setting duplex for the 3cSOHO100-TX was more or less a random process.
Till 2.6.15 it was more likely that the diver ends up in half
duplex mode, after the code change in 2.6.16 it was more likely
to end up in full duplex mode. I wonder why nobody noticed this earier.
Hopefully addresses
