Yeah, this is hideous.
Please either do it in one header:
#ifdef x86..
static inline int arch_reserved_keys(void)
{
}
...
#elif ppc
static inline int arch_reserved_keys(void)
{
}
...
#else
#error
#endif
Or in multiple:
#ifdef x86..
#include <pkey_x86.h>
#elif ppc
#include <pkey_ppc.h>
#else
#error
#endif
