[valgrind] [Bug 352197] mips32: mmap2() not wrapped correctly for page size > 4096

There is no path for mmap2() for MIPS64. That syscall is not supported
on MIPS64, as there is no need for it since the offset is already
64-bit.

This should be fixed now with:
- VEX r3261
- Valgrind r16039

Can you please sync up the latest Valgrind code and check if it works for you?

Thanks.

[valgrind] [Bug 370028] Reduce the number of compiler warnings on MIPS platforms

[Petar Jovanovic via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=370028

--- Comment #6 from Petar Jovanovic  ---
Most of these patches are not MIPS-specific, touch common code and
probably remove warnings on different platforms too.
Can others take a look at these as well?

@Aleksandar
Can you write which patch removes what warning?

Can you make similar changes for MIPS64 for prctl(GET/SET_FP_MODE), so this
test can be correctly executed for MIPS64 as well?
