Documentation/process/license-rules.rst and checkpatch expect the SPDX
identifier syntax for multiple licenses to use capital "OR". Correct it
to keep consistent format and avoid copy-paste issues.

The __assign_str macro has an unusual ending semicolon but the vast
majority of uses of the macro already have semicolon termination.
$ git grep -P '\b__assign_str\b' | wc -l
551
$ git grep -P '\b__assign_str\b.*;' | wc -l
480
Add semicolons to the __assign_str() uses without semicolon termination
and all the other uses without semicolon termination via additional defines
that are equivalent to __assign_str() with the eventual goal of removing
the semicolon from the __assign_str() macro definition.

This patch adds a trace for putting a TID and
for writing the RcvArray CSR.
The CSR access template can be easily extended for additional
CSR readq/writeq calls.

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.

The ftrace infrastructure used to evaluate the TRACE_SYSTEM
macro on every DEFINE_EVENT() macro. Now the TRACE_SYSTEM
macro only gets evaluated when trace/define_trace.h is
included, so the group event information is lost. This was
introduced in
commit acd388fd3af3 ("tracing: Give system name a pointer")
Therefore, each system tracepoint must be on its own file.
