Both the fill_ipi_map() routine and the gic_intr_map array defined
in arch/mips/mips-boards/malta/malta_int.c are not used outside of

these two objects are used by the MT code only, which is why this
patch adds the appropriate ifdef.

While at it, this patch removes an unnecessary preprocessing macro
in favor of the commonly used ARRAY_SIZE.

94daeb9069 [MIPS] Fix asm constraints for 'ins' instructions.
The third operand to 'ins' must be a constant int, not a register.

[Ralf: The bug was actually intensional.  Some versions used to throw an
error under certain circumstances for code like:

static inline void f(unsigned nr, unsigned *p)
{
	unsigned short bit = nr & 5;

	if (__builtin_constant_p(bit)) {
		__asm__ __volatile__ ("  foo %0, %1" : "=m" (*p) : "i" (bit));
  	} else {
		/* Do something else. */
	}
}

because gcc was not able to figure out that the "i" constraint was possibly
at the early stage when the constraint are getting verified.  The solution
was using "ri" instead of "i".  The "ri" would keep gcc happy but in the
end for code generation always the "i" constraint would be satisfied.  The
problem afair originally appeared in the i386 io.h and also hit it's mips
equivalent.  From there the workaround spread to many of the inline
assembler functions.]
