MIPS is no longer part of Imagination Technologies and my @imgtec.com
address will soon stop working. Update any files containing my address
as well as the .mailmap to point to my new @mips.com address.

MIPS: tracing: disable uprobe/kprobe on compact branch instructions2016-10-06T15:37:40ZMarcin Nowakowski2016-09-30T09:33:46Zurn:sha1:d05c513069f15be5de766026a4192998688ffff1
Current instruction decoder for uprobe/kprobe handler only handles
branches with delay slots. For compact branches the behaviour is rather
unpredictable - and depending on the encoding of a compact branch
instruction may result in one (or more) of:
- executing an instruction that follows a branch which wasn't in a delay
slot and shouldn't have been executed
- incorrectly emulating a branch leading to a jump to a wrong location
- unexpected branching out of the single-stepped code and never reaching
the breakpoint that should terminate the probe handler
Results of these actions are generally unpredictable, but can end up
with a probed application or kernel crash, so disable placing probes on
compact branches until they are handled properly.

MIPS: tracing: move insn_has_delay_slot to a shared header2016-10-06T15:36:39ZMarcin Nowakowski2016-09-30T09:33:45Zurn:sha1:e3031b32840c1bee228c58bb284ebc05f97249c7
Currently both kprobes and uprobes code have definitions of the
insn_has_delay_slot method. Move it to a separate header as an inline
method that each probe-specific method can later use.
No functional change intended, although the methods slightly varied in
the constraints they set for the methods - the uprobes one was chosen as
it is slightly more specific when filtering opcode fields.
