This is done in two steps:
1) Issuing CREATE_VPORT_LAG in order to have Ethernet traffic from
both ports arriving on PF0 root flowtable, so we will be able to catch
all raw-eth traffic on PF0.
2) Creation of LAG demux flowtable in order to direct all non-raw-eth
traffic back to its source port, assuring that normal Ethernet
traffic "jumps" to the root flowtable of its RX port (non-LAG behavior).

Since ib_query_port() in RoCE returns the state of its netdev as the port

This also keeps both the event and ib_query_port() synchronized.

Flow steering specifications structures were implemented as in an
extensible way that allows one to add new filters and new fields
to existing filters.
These specifications have never been extended, therefore the
kernel flow specifications size and the user flow specifications size
were must to be equal.
In downstream patch, the IPv4 flow specifications type is extended to
support TOS and TTL fields.
To support an extension we change the flow specifications size
condition test to be as following:
* If the user flow specifications is bigger than the kernel
specifications, we verify that all the bits which not in the kernel
specifications are zeros and the flow is added only with the kernel
specifications fields.
* Otherwise, we add flow rule only with the user specifications fields.
User space filters must be aligned with 32bits.

Increase the initial kernel default page mapping size for SMP kernels to 32MB
and add a runtime check which panics early if the kernel is bigger than the
initial mapping size.
This fixes boot crashes of 32bit SMP kernels. Due to the introduction of huge
page support in kernel 4.4 and it's required initial kernel layout in memory, a
32bit SMP kernel usually got bigger (in layout, not size) than 16MB.

Memblock is the standard kernel boot-time memory tracker/allocator. Use it
instead of the bootmem allocator. This allows using kmemleak, CMA and
other features.
Signed-off-by: Helge Deller <deller@gmx.de>
When a CPU is physically added to a system then the MADT table is not
updated.
If subsequently a kdump kernel is started on that physically added CPU then
the ACPI enumeration fails to provide the information for this CPU which is
now the boot CPU of the kdump kernel.
As a consequence, generic_processor_info() is not invoked for that CPU so
the number of enumerated processors is 0 and none of the initializations,
including the logical package id management, are performed.
We have code which relies on the correctness of the logical package map and
other information which is initialized via generic_processor_info().
Executing such code will result in undefined behaviour or kernel crashes.
This problem applies only to the kdump kernel because a normal kexec will
switch to the original boot CPU, which is enumerated in MADT, before
jumping into the kexec kernel.
The boot code already has a check for num_processors equal 0 in
prefill_possible_map(). We can use that check as an indicator that the
enumeration of the boot CPU did not happen and invoke generic_processor_info()
for it. That initializes the relevant data for the boot CPU and therefore
prevents subsequent failure.

This is bit large pile of code which bring in some nice additions:
- Error reporting: we have added a new mechanism for users of dmaenegine to
register a callback_result which tells them the result of the dma
transaction. Right now only one user ntb is using it.
- As we discussed on KS mailing list and pointed out NO_IRQ has no place in
kernel, this also remove NO_IRQ from dmaengine subsystem (both arm and
ppc users)
- Support for IOMMU slave transfers and it implementation for arm.
- To get better build coverage, enable COMPILE_TEST for bunch of driver,
and fix the warning and sparse complaints on these.
- Apart from above, usual updates spread across drivers.
