An IPsec node speaking IKEv2 MUST accept incoming UDP encapsulated
ESP packets, even if no NAT situation is detected. This is important
if MOBIKE is in use. Some implementation keep the encapsulation
mode if they move out of a NAT situation.

MIPS: o32: Fix number of arguments to splice(2).
The syscall code was assuming splice only takes 4 arguments so no stack
arguments were being copied from the userspace stack to the kernel stack.
As the result splice was likely to fail with EINVAL.

With the conversion of MIPS to RTC_LIB the old RTC driver CONFIG_RTC became
unselectable. Fix by setting up a platform device. Also enable
RTC_CLASS so system time gets set from RTC on kernel initialization.

MIPS: Fix potential DOS by untrusted user app.
On a 64 bit kernel if an o32 syscall was made with a syscall number less
than 4000, we would read the function from outside of the bounds of the
syscall table. This led to non-deterministic behavior including system
crashes.
While we were at it we reworked the 32 bit version as well to use fewer
instructions. Both 32 and 64 bit versions are use the same code now.

linking order was not kept for sparc64 with this change.
It was not possible to keep linking order for both sparc and sparc64
and as sparc64 see more testing than sparc it was natural to
break linking order on sparc64. Should it have any effect it
would be detected sooner this way.
printf_32.c and printf_64.c are obvious candidates to be merged
but they are not 100% equal so that was left for later
