36de48de85 [MIPS] DECstation: Optimised early printk()
This is an optimised implementation of early printk() for the DECstation.  
After the recent conversion to a MIPS-specific generic routine using a 
character-by-character output the performance dropped significantly.  
This change reverts to the previous speed -- even at 9600 bps of the 
serial console the difference is visible with a naked eye; I presume for a 
framebuffer it is even worse (it may depend on exactly which one is used 
though).

 Additionally the change includes a fix for a problem that the old 
implementation had -- the format used would not actually limit the length 
of the string output.  This new implementation uses a local buffer to deal 
with it -- even with this additional copying it is much faster than the 
generic function.

 Plus this driver is registered much earlier than the generic one, 
allowing one to see critical messages, such as one about an incorrect CPU 
setting used, that are produced beforehand. :-)

b1c65b3988 [MIPS] Fix PHYS_OFFSET for 64-bits kernels with 32-bits symbols
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.

09bb9ce15f [MIPS] Allow generic spaces.h to be included by platform specific ones
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.

44e4925e46 e100: Fix Tyan motherboard e100 not receiving IPMI commands
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.

7a62755821 spidernet: improve interrupt handling
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.

b8a1fcee26 3cSOHO100-TX needs EXTRA_PREAMBLE
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
