why no different definitions of __pte

Hi,

In include/asm-i386/page.h, the pte_t is defined like this

#ifdef CONFIG_X86_PAE
typedef struct { unsigned long pte_low, pte_high; } pte_t;
#else
typedef struct { unsigned long pte_low; } pte_t;
#endif

in other words, the pte_t is defined according to two situations
respectively. But, a subsequent macro

#define __pte(x) ((pte_t) { (x) } )

is unique yet.

In PAE's case, I think that the __pte should have two parameters that
doesn't exist at all. This really puzzle me.
