There's a chance that the receive buffers are being consumed at the same
rate as they are being replenished in ibmveth_replenish_task()... 
Meanwhile, the calls to schedule_replenishing() from ibmveth_poll() won't
schedule another replenishing cycle (because the not_replenishing flag is
zero), starving the buffers and making the adapter unable to receive
packets unless the module is reloaded...  Here's a small patch that will
fix it by scheduling another replenishing task after toggling the
not_replenishing flag.

Patch from Marc Singer

Add support for the LPD7a40x implementation of the SMC91x ethernet
controller. This patch exists to work around a mismatch between the
way the LH7a40x CPUs handle chip selects and what the ethernet
controller expects.

This patch has been revised to eliminate masking of interrupts.  The
concessions are that 

  a) the ISR must perform an IOBARRIER before the first access to the
     chip, just in case the interrupt occurred while the driver was
     writing to the chip
  b) other drivers that use the same chip select region as the SMC
     chip must perform a similar IOBARRIER at the top of their ISRs.

Some time ago, a patch was merged that removed pci_save_state() and
pci_restore_state() from various ALSA drivers. That patch also added
pci_restore_state() to sound/core/init.c but didn't add pci_save_state()
anywhere. This is needed since the core pci handling doesn't do this for
us anymore.

We have to load the bigkernel second TLB entry on
secondary processors before we move over the use
the kernel trap table.  Otherwise we can take a
TLB miss somewhere in the post-4MB area and the
TLB handler is not prepared to service that.

The case that usually occurs is the prom_set_trap_table
call made by trampoline.S, since p1275buf usually sits
very near the end of the kernel image.  It worked by
luck most of the time as long as p1275buf sits within
a single page since earlier code running in trampoline.S
forced that TLB entry to be loaded by the OBP TLB miss
handler.

This was not fun to figure out.

Hardware: CyberBlade/i1 on VIA Epia-800

Problem Description:  When the framebuffer is set to 16 bpp, console's text
colours are incorrect.  For example, white becomes yellow, black becomes blue, etc.

Steps to reproduce:
1. Load tridentfb
2. Use "setterm -n -depth 16" to request 16 bpp framebuffer

The problem arose from the fact that each psuedo palette entry should be
32-bit in size, even under 16-bit display mode.

This patch avoids a deadlock on rtnl_sem in smc_close() when bringing down
an smc91x interface.  The semaphore is already held by devinet_ioctl() and
the pending work queue contains linkwatch_event() (scheduled by
netif_carrier_off()) which also wants rtnl_sem hence it is unsafe to call
flush_scheduled_work().

The solution is to track whether we have any pending work of our own and
wait for that instead of flushing the entire queue.

I also fixed a typo 'ence' -> 'Hence' and renamed smc_detect_phy to
smc_phy_detect in order to follow the same pattern as the other smc_phy_*
functions.

We check need_resched() _before_ disabling preemption.  This opens up the
following scenario:

 swapper:	!need_resched()
 [IRQ context]
		wakes up a task
		marks idle task as need-resched

 swapper:	acpi_processor_idle(); // sleeps until next irq

instant 1msec latency introduced...

normally default_idle() is safe because it re-checks need_resched with
interrupts disabled before it truly halts the CPU.  But
acpi_processor_idle() doesnt seem to be doing this!  Your trace clearly
shows a missed preemption due to ACPI.  I'm wondering why no-one has
triggered this before, it's a really bad bug that should be fixed in
2.6.10.
