staging: comedi: das08: separately configure ISA and PCI
The das08 driver supports both ISA and PCI cards, but currently is
configured outside the ISA and PCI comedi driver sections. The module
is also used by the das08_cs driver. This patch splits the
configuration to make the ISA and PCI parts separately selectable, and
changes the driver to only include the selected ISA and/or PCI board
types. Also, if neither the ISA or PCI parts are selected, and the
module is only needed for the das08_cs driver, don't register the driver
as a comedi driver as it doesn't have any boards to support.

cases, because calling that function in that context would free
memory that was in use. The aborted flag allows the lifetime to

Make the "word-at-a-time" helper functions more commonly usable
I have a new optimized x86 "strncpy_from_user()" that will use these
same helper functions for all the same reasons the name lookup code uses
them. This is preparation for that.
This moves them into an architecture-specific header file. It's
architecture-specific for two reasons:
- some of the functions are likely to want architecture-specific
implementations. Even if the current code happens to be "generic" in
the sense that it should work on any little-endian machine, it's
likely that the "multiply by a big constant and shift" implementation
is less than optimal for an architecture that has a guaranteed fast
bit count instruction, for example.
- I expect that if architectures like sparc want to start playing
around with this, we'll need to abstract out a few more details (in
particular the actual unaligned accesses). So we're likely to have
more architecture-specific stuff if non-x86 architectures start using
this.
(and if it turns out that non-x86 architectures don't start using
this, then having it in an architecture-specific header is still the
right thing to do, of course)

From Eric Dumazet.

Fixes from Eric Dumazet.
13) PPP has this annoying behavior in that for every transmit call it
immediately stops the TX queue, then calls down into the next layer
to transmit the PPP frame.
But if that next layer can take it immediately, it just un-stops the
TX queue right before returning from the transmit method.
Besides being useless work, it makes several facilities unusable, in
particular things like the equalizers. Well behaved devices should
only stop the TX queue when they really are full, and in PPP's case
when it gets backlogged to the downstream device.
David Woodhouse therefore fixed PPP to not stop the TX queue until
it's downstream can't take data any more.

xen/pcifront: avoid pci_frontend_enable_msix() falsely returning success
The original XenoLinux code has always had things this way, and for
compatibility reasons (in particular with a subsequent pciback
adjustment) upstream Linux should behave the same way (allowing for two
distinct error indications to be returned by the backend).

xen/pciback: fix XEN_PCI_OP_enable_msix result
Prior to 2.6.19 and as of 2.6.31, pci_enable_msix() can return a
positive value to indicate the number of vectors (less than the amount
requested) that can be set up for a given device. Returning this as an
operation value (secondary result) is fine, but (primary) operation
results are expected to be negative (error) or zero (success) according
to the protocol. With the frontend fixed to match the XenoLinux
behavior, the backend can now validly return zero (success) here,
passing the upper limit on the number of vectors in op->value.

The reason we are dying is b/c the call acpi_get_override_irq() is used,
which returns the polarity and trigger for the IRQs. That function calls
mp_find_ioapics to get the 'struct ioapic' structure - which along with the
mp_irq[x] is used to figure out the default values and the polarity/trigger
overrides. Since the mp_find_ioapics now returns -1 [b/c the IOAPIC is filled
with 0xffffffff], the acpi_get_override_irq() stops trying to lookup in the
mp_irq[x] the proper INT_SRV_OVR and we can't install the SCI interrupt.
The proper fix for this is going in v3.5 and adds an x86_io_apic_ops
struct so that platforms can override it. But for v3.4 lets carry this
work-around. This patch does that by providing a slightly different variant
of the fake IOAPIC entries.
