sky2: FE+ vlan workaround
sky2: sky2 FE+ receive status workaround
in cpm_uart_cpm1.h, DPRAM_BASE is assigned an address derived from cpmp.
On ARC=ppc, this is a physical address with 1:1 DMA mapping which can't
be used for arithmetric compare operations with virtual addresses
returned by cpm_dpram_addr. This patch changes the assignment to use
cpm_dpram_addr as well, like in cpm_uart_cpm2.h.

After resume, driver has reset the chip so the current state
of transmit checksum offload state machine and DMA state machine
will be undefined.
The fix is to set the state so that first Tx will set MSS and offset
values.

The FE+ workaround means the driver can no longer trust the status register
to indicate VLAN tagged frames. The fix for this is to just disable VLAN
acceleration for that chip version. Tested and works fine.

The Yukon FE+ chip appears to have a hardware glitch that causes bogus
receive status values to be posted. The data in the packet is good, but
the status value is random garbage. As a temporary workaround until the
problem is better understood, implement the workaround the vendor driver
used of ignoring the status value on this chip.
Since this means trusting dodgy hardware values; add additional checking
of the receive packet length.

As Stephen Hemminger says, this is a "belt and suspenders" patch that
zeroes the envp array at allocation time, even though all the users
should NULL-terminate it anyway (and we've hopefully fixed everybody
that doesn't do that).
And we'll apparently clean the whole envp thing up for 2.6.24 anyway.
But let's just be robust, and do both this *and* make sure that all
users are doing the right thing.

missing udma timing value for UDMA100. According to sis5513, this

When PCIX_IRQ_WOC is used, sil24 has an inherent race condition
between clearing IRQ pending and reading IRQ status. If IRQ pending
is cleared after reading IRQ status, there's possibility of lost IRQ.
If IRQ pending is cleared before reading IRQ status, spurious IRQs
will occur.
sata_sil24 till now cleared IRQ pending after reading IRQ status thus
losing IRQs on machines where PCIX_IRQ_WOC was used. Reverse the
order and ignore spurious IRQs if PCIX_IRQ_WOC.

If hpet has been initialized before registering hpet driver, the callback
function of hpet_resources will return the status code of -EBUSY, which is
not defined in the ACPI exception table. So when ACPI checks the status
code of callback function, it will report the unknown exception code.
So the status code in ACPI is used instead of the generic error code in the
ACPI callback function of hpet_resources.
For example: -EBUSY is replaced by AE_ALREADY_EXISTS
-EINVAL is replaced by AE_NO_MEMORY

1/ ops_complete_biofill tried to avoid calling handle_stripe since all the
state necessary to return read completions is available. However the
process of determining whether more read requests are pending requires
locking the stripe (to block add_stripe_bio from updating dev->toead).
ops_complete_biofill can run in tasklet context, so rather than upgrading
all the stripe locks from spin_lock to spin_lock_bh this patch just
unconditionally reschedules handle_stripe after completing the read
request.
2/ ops_complete_biofill needlessly qualified processing R5_Wantfill with
dev->toread. The result being that the 'biofill' pending bit is cleared
before handling the pending read-completions on dev->read. R5_Wantfill can
be unconditionally handled because the 'biofill' pending bit prevents new
R5_Wantfill requests from being seen by ops_run_biofill and
ops_complete_biofill.

IB/mlx4: Fix data corruption triggered by wrong headroom marking order
This is an addendum to commit 0e6e7416 ("IB/mlx4: Handle new FW
requirement for send request prefetching"). We also need to handle
prefetch marking properly for S/G segments, or else the HCA may end up
processing S/G segments that are not fully written and end up sending
the wrong data. This can actually cause data corruption in practice,
especially on systems with relatively slow CPUs (where the HCA is more
likely to prefetch while the CPU is in the middle of writing a work
request into memory).
We write S/G segments in reverse order into the WQE, in order to
guarantee that the first dword of all cachelines containing S/G
segments is written last (overwriting the headroom invalidation
pattern). The entire cacheline will thus contain valid data when the
invalidation pattern is overwritten.

device_suspend() calls ACPI suspend functions, which seems to have undesired
side effects on lower idle C-states. It took me some time to realize that
especially the VAIO BIOSes (both Andrews jinxed UP and my elfstruck SMP one)
show this effect. I'm quite sure that other bug reports against suspend/resume
about turning the system into a brick have the same root cause.
After fishing in the dark for quite some time, I realized that removing the ACPI
processor module before suspend (this removes the lower C-state functionality)
made the problem disappear. Interestingly enough the propability of having a
bricked box is influenced by various factors (interrupts, size of the ram image,
...). Even adding a bunch of printks in the wrong places made the problem go
away. The previous periodic tick implementation simply pampered over the
problem, which explains why the dyntick / clockevents changes made this more
prominent.
We avoid complex functionality during the boot process and we have to do the
same during suspend/resume. It is a similar scenario and equaly fragile.
Add suspend / resume functions to the ACPI processor code and disable the lower
idle C-states across suspend/resume. Fall back to the default idle
implementation (halt) instead.

Domain Validation in the SPI transport class is failing on boxes with
damaged cables (and failing to the extent that the box hangs). The
problem is that the first test it does is a cable integrity test for
wide transfers and if this fails, it turns the wide bit off. The
problem is that the next set of tests it does turns wide back on
again, with the result that it runs through the entirety of DV with a
known bad setting and then hangs the system.
The attached patch fixes the problem by physically nailing the wide
setting to what it deduces it should be for the whole of Domain
Validation.
