Fix up trivial conflict in fs/gfs2/file.c (llseek changes)
This was found by inspection while tracking a similar
bug in compat_statfs64, that has been fixed in mainline
since decemeber.
- This fixes a bug where not all of the f_spare fields
were cleared on mips and s390.
- Add the f_flags field to struct compat_statfs
- Copy f_flags to userspace in case someone cares.
- Use __clear_user to copy the f_spare field to userspace
to ensure that all of the elements of f_spare are cleared.
On some architectures f_spare is has 5 ints and on some
architectures f_spare only has 4 ints. Which makes
the previous technique of clearing each int individually
broken.
I don't expect anyone actually uses the old statfs system
call anymore but if they do let them benefit from having
the compat and the native version working the same.

Later IRIX versions provide them in <sys/regdef.h> and gas also accepts
$ta0 .. $ta3 since binutils 2.18 so Linux should do the same for source
compatibility.
The hard coded constants are moved to struct mips_pmu. All counter
register access move to the read_counter and write_counter function
pointers, which are set to either 32-bit or 64-bit access methods at
initialization time.
Many of the function pointers in struct mips_pmu were not needed as
there was only a single implementation, these were removed.
I couldn't figure out what made struct cpu_hw_events.msbs[] at all
useful, so I removed it too.
Some functions and other declarations were reordered to reduce the
need for forward declarations.

The contents of arch/mips/kernel/perf_event.c and

I moved all the hardware counter support code to perf_event_mipsxx.c
and removed the gating #ifdefs to the Kconfig and Makefile.
Now perf_event.c contains only the callchain support, everything else
is in perf_event_mipsxx.c
There are no code changes, only moving of functions from one file to
the other, or removing empty unneeded functions.

further build errors and suboptimal generation even in violation of the
