An SR-IOV capable device includes an SR-IOV PCIe capability which
describes the Virtual Function (VF) BAR requirements. A typical SR-IOV
device can support multiple VFs whose BARs must be in a contiguous region,
effectively an array of VF BARs. The BAR reports the size requirement
for a single VF. We calculate the full range needed by simply multiplying
the VF BAR size with the number of possible VFs and create a resource
spanning the full range.
This all seems sane enough except it artificially inflates the alignment
requirement for the VF BAR. The VF BAR need only be aligned to the size
of a single BAR not the contiguous range of VF BARs. This can cause us
to fail to allocate resources for the BAR despite the fact that we
actually have enough space.
This patch adds a thin PCI specific layer over the generic
resource_alignment() function which is aware of the special nature of
VF BARs and does sorting and allocation based on the smaller alignment
requirement.
I recognize that while resource_alignment is generic, it's basically a
PCI helper. An alternative to this patch is to add PCI VF BAR specific
information to struct resource. I opted for the extra layer rather than
adding such PCI specific information to struct resource. This does
have the slight downside that we don't cache the BAR size and re-read
for each alignment query (happens a small handful of times during boot
for each VF BAR).

Use VBT information to determine which DDC bus to use for CRTDCC.
Fall back to GPIOA if VBT info is not available.

As struct skcipher_givcrypt_request includes struct crypto_request
at a non-zero offset, testing for NULL after converting the pointer
returned by crypto_dequeue_request does not work. This can result
in IPsec crashes when the queue is depleted.
This patch fixes it by doing the pointer conversion only when the
return value is non-NULL. In particular, we create a new function
__crypto_dequeue_request that does the pointer conversion.

Yes - Line 535 should use both [0] and [1].

-tip testing found that this patch breaks the build on x86 if
CONFIG_KALLSYMS is disabled:
kernel/module.c: In function ‘load_module’:
kernel/module.c:2367: error: ‘struct module’ has no member named ‘sect_attrs’
distcc[8269] ERROR: compile kernel/module.c on ph/32 failed
make[1]: *** [kernel/module.o] Error 1
make: *** [kernel] Error 2
make: *** Waiting for unfinished jobs....
Commit 1b364bf misses the fact that section attributes are only
built and dealt with if kallsyms is enabled. The patch below fixes
this.
( note, technically speaking this should depend on CONFIG_SYSFS as
well but this patch is correct too and keeps the #ifdef less
intrusive - in the KALLSYMS && !SYSFS case the code is a NOP. )
