Add ability to fault packets on transmit by opcode.
Dropping by packet can be achieved by setting the mask to 0.

In order to drop non-verbs traffic we set PbcInsertHrc
to NONE (0x2). The packet will still be delivered to
the receiving node but a KHdrHCRCErr (KDETH packet
with a bad HCRC) will be triggered and the packet will
not be delivered to the correct context.

In order to drop regular verbs traffic we set the
PbcTestEbp flag. The packet will still be delivered
to the receiving node but a 'late ebp error' will
be triggered and will be dropped.

A global toggle (/sys/kernel/debug/hfi1/hfi1_X/fault_suppress_err)
has been added to suppress the error messages on the receive
node when a packet was faulted on the sending node.

Add fault injection capability:
  - Drop packets unconditionally (fault_by_packet)
  - Drop packets based on opcode (fault_by_opcode)

This feature reacts to the global FAULT_INJECTION
config flag.

The faulting traces have been added:
  - misc/fault_opcode
  - misc/fault_packet

See 'Documentation/fault-injection/fault-injection.txt'
for details.

Examples:
  - Dropping packets by opcode:
    /sys/kernel/debug/hfi1/hfi1_X/fault_opcode
	# Enable fault
	echo Y > fault_by_opcode
	# Setprobability of dropping (0-100%)
	# echo 25 > probability
	# Set opcode
	echo 0x64 > opcode
	# Number of times to fault
	echo 3 > times
	# An optional mask allows you to fault
	# a range of opcodes
	echo 0xf0 > mask
    /sys/kernel/debug/hfi1/hfi1_X/fault_stats
    contains a value in parentheses to indicate
    number of each opcode dropped.

  - Dropping packets unconditionally
    /sys/kernel/debug/hfi1/hfi1_X/fault_packet
	# Enable fault
	echo Y > fault_by_packet
    /sys/kernel/debug/hfi1/hfi1_X/fault_packet/fault_stats
    contains the number of packets dropped.

This patch adds the standard fd based type - completion_channel.
The completion_channel is now prefixed with ib_uobject, similarly
to the rest of the uobjects.
This requires a few changes:
(1) We define a new completion channel fd based object type.
(2) completion_event and async_event are now two different types.
    This means they use different fops.
(3) We release the completion_channel exactly as we release other
    idr based objects.
(4) Since ib_uobjects are already kref-ed, we only add the kref to the
    async event.

A fd object requires filling out several parameters. Its op pointer
should point to uverbs_fd_ops and its size should be at least the
size if ib_uobject. We use a macro to make the type declaration
easier.

The completion channel we use in verbs infrastructure is FD based.

This commit adds the necessary mechanism to support FD based objects
like their IDR counterparts. FD objects release need to be synchronized

When two handlers used the same object in the old schema, we blocked
the process in the kernel. The new schema just returns -EBUSY. This
could lead to different behaviour in applications between the old
schema and the new schema. In most cases, using such handlers
concurrently could lead to crashing the process. For example, if
thread A destroys a QP and thread B modifies it, we could have the
destruction happens before the modification. In this case, we are
accessing freed memory which could lead to crashing the process.
This is true for most cases. However, attaching and detaching
a multicast address from QP concurrently is safe. Therefore, we
preserve the original behaviour by adding a lock there.

This changes only the handlers which deals with idr based objects to
use the new idr allocation, fetching and destruction schema.
This patch consists of the following changes:
(1) Allocation, fetching and destruction is done via idr ops.
(2) Context initializing and release is done through
    uverbs_initialize_ucontext and uverbs_cleanup_ucontext.
(3) Ditching the live flag. Mostly, this is pretty straight
    forward. The only place that is a bit trickier is in
    ib_uverbs_open_qp. Commit [1] added code to check whether
    the uobject is already live and initialized. This mostly
    happens because of a race between open_qp and events.
    We delayed assigning the uobject's pointer in order to
    eliminate this race without using the live variable.

The new ioctl infrastructure supports driver specific objects.
Each such object type has a hot unplug function, allocation size and
an order of destruction.

When a ucontext is created, a new list is created in this ib_ucontext.
This list contains all objects created under this ib_ucontext.
When a ib_ucontext is destroyed, we traverse this list several time
destroying the various objects by the order mentioned in the object
type description. If few object types have the same destruction order,
they are destroyed in an order opposite to their creation.

Adding an object is done in two parts.
First, an object is allocated and added to idr tree. Then, the
command's handlers (in downstream patches) could work on this object
and fill in its required details.
After a successful command, the commit part is called and the user
objects become ucontext visible. If the handler failed, alloc_abort
should be called.

Removing an uboject is done by calling lookup_get with the write flag
and finalizing it with destroy_commit. A major change from the previous
code is that we actually destroy the kernel object itself in
destroy_commit (rather than just the uobject).

We should make sure idr (per-uverbs-file) and list (per-ucontext) could
be accessed concurrently without corrupting them.

actually problematic afaik.

the real fix is to just remove it entirely, but for now we'll warn about
