v1->v2:
- clarify effects of the first patch in its commit message
- marked the first patch as "stable #4.3+"
- replaced "Minor" with "Misc" in the series title and
cover letter
This series contains two misc FPU emulation patches that
were not included into a recent larger series of FPU fixes,
mainly not to additionally burden already complex set of
patches.
Only the first patch changes functionality.
The second one is just a cosmetic change - it just cleans
the code, and removes some checkpatch warnings.

From: Aleksandar Markovic <aleksandar.markovic@mips.com>
Fix omission of updating of debugfs FP exception stats for
instructions <CLASS|MADDF|MSUBF|MAX|MIN|MAXA|MINA>.<D|S>.
CLASS.<D|S> instruction can generate "Unimplemented Operation"
FP exception. <MADDF|MSUBF>.<D|S> can generate "Inexact",
"Unimplemented Operation", "Invalid Operation", "Overflow",
and "Underflow" FP exceptions. <MAX|MIN|MAXA|MINA>.<D|S> can
generate "Unimplemented Operation" and "Invalid Operation" FP
exceptions. In all such cases (and prior to this patch),
SIGFPE signal was not generated, even though, according to
its specifications, it should be. Also, debugfs FP exception
stats were not updated, and therefore contained overall
wrong values.
This patch fixes those problems, and brings the emulation
of mentioned instructions consistent with the previously
implemented emulation of other related FPU instructions
(ADD, SUB, etc.).
Fixes: 38db37ba069f ("MIPS: math-emu: Add support for the MIPS R6 CLASS FPU instruction")
Fixes: e24c3bec3e8e ("MIPS: math-emu: Add support for the MIPS R6 MADDF FPU instruction")
Fixes: 83d43305a1df ("MIPS: math-emu: Add support for the MIPS R6 MSUBF FPU instruction")
Fixes: a79f5f9ba508 ("MIPS: math-emu: Add support for the MIPS R6 MAX{, A} FPU instruction")
Fixes: 4e9561b20e2f ("MIPS: math-emu: Add support for the MIPS R6 MIN{, A} FPU instruction")

From: Aleksandar Markovic <aleksandar.markovic@mips.com>
Fix occurences of unsigned integer declarations that are not
preferred by standards of checkpatch scripts. This removes
significant number of checkpatch warnings in math-emu
directory (several files will become completely warning-free),
and thus makes easier to spot (now and in the future) other
perhaps more significant checkpatch errors and warnings.
