Syscall wrappers breaks things.

[David Daney <ddaney@caviumnetworks.com>]

In commit ee6a093222549ac0c72cfd296c69fa5e7d6daa34 the syscall wrappers 
infrastructure was introduced.

A typical definition is something like this (from Ralf's patch):

SYSCALL_DEFINE6(32_ipc, u32, call, long, first, long, second, long, third,
	unsigned long, ptr, unsigned long, fifth)
{
.
.
.

This creates a symbol sys_32_ipc.  The old name of the symbol is 
sys32_ipc (note the change in the number of '_').

For the mips64 kernel the syscall table for o32 ABI executable contains:

.
.
.
	PTR	sys32_ipc
.
.
.

This is now linked to the sys32_ipc function in kernel/sys_ni.c which 
kindly returns ENOSYS.

The long and short of the problem is that the is now a kernel wide 
mismatch in function names between the names created by SYSCALL_DEFINE*, 
the syscall tables and kernel/sys_ni.c.

I am not sure what the best solution is, but something should probably 
be done to un-break things.

Thanks,
