Add #include <linux/cred.h> dependencies to all .c files rely on sched.h
doing that for them.
Note that even if the count where we need to add extra headers seems high,
it's still a net win, because <linux/sched.h> is included in over
2,200 files ...

Pull cgroup updates from Tejun Heo:
"Several noteworthy changes.
- Parav's rdma controller is finally merged. It is very straight
forward and can limit the abosolute numbers of common rdma
constructs used by different cgroups.
- kernel/cgroup.c got too chubby and disorganized. Created
kernel/cgroup/ subdirectory and moved all cgroup related files
under kernel/ there and reorganized the core code. This hurts for
backporting patches but was long overdue.
- cgroup v2 process listing reimplemented so that it no longer
depends on allocating a buffer large enough to cache the entire
result to sort and uniq the output. v2 has always mangled the sort
order to ensure that users don't depend on the sorted output, so
this shouldn't surprise anybody. This makes the pid listing
functions use the same iterators that are used internally, which
have to have the same iterating capabilities anyway.
- perf cgroup filtering now works automatically on cgroup v2. This
patch was posted a long time ago but somehow fell through the
cracks.
- misc fixes asnd documentation updates"

Pull rdma DMA mapping updates from Doug Ledford:
"Drop IB DMA mapping code and use core DMA code instead.
Bart Van Assche noted that the ib DMA mapping code was significantly
similar enough to the core DMA mapping code that with a few changes it
was possible to remove the IB DMA mapping code entirely and switch the
RDMA stack to use the core DMA mapping code.
This resulted in a nice set of cleanups, but touched the entire tree
and has been kept separate for that reason."

A QP in that state cannot send requests, but it can be the target

Having per-CPU reference count for each MR prevents
cache-line bouncing across the system. Thus, it
prevents bottlenecks. Use per-CPU reference counts
per MR.
The per-CPU reference count for FMRs is used in
atomic mode to allow accurate testing of the busy
state. Other MR types run in per-CPU mode MR until
they're freed.

Expose raw packet capabilities in the core layer to enable a device

Two existing capabilities, scatter FCS and IP CSUM were added to this
field for a better user experience by exposing the raw packet caps
from one location.
This field will serve also for future capabilities for raw packet QP.
A new capability was introduced - cvlan stripping, which is the
device's ability to remove cvlan tag from an incoming packet and
report it in the matching work completion.

The RDMA core uses ib_pack() to convert from unpacked CPU structs
to on-the-wire bitpacked structs.
This process requires that 1 bit fields are declared as u8 in the
unpacked struct, otherwise the packing process does not read the
value properly and the packed result is wired to 0. Several
places wrongly used int.
Crucially this means the kernel has never, set reversible
correctly in the path record request. It has always asked for
irreversible paths even if the ULP requests otherwise.
When the kernel is used with a SM that supports this feature, it
completely breaks communication management if reversible paths are
not properly requested.
The only reason this ever worked is because opensm ignores the
reversible bit.

In order to support tunneling, that can be used by the QP,
both struct ib_flow_spec_tunnel and struct ib_flow_tunnel_filter can be
used to more IP or UDP based tunneling protocols (e.g NVGRE, GRE, etc).
IB_FLOW_SPEC_VXLAN_TUNNEL type flow specification is added to use this
functionality and match specific Vxlan packets.
In similar to IPv6, we check overflow of the vni value by
comparing with the maximum size.
