solution would be to CALL_FMT1 as
#define CALL_FMT1 CALL_FMT_0

The trap4 instruction is a suitable one. The patch would look like this

Change the currently empty defines for __PAGETABLE_PMD_FOLDED,
__PAGETABLE_PUD_FOLDED and __PAGETABLE_P4D_FOLDED to return 1.
This makes it possible to use __is_defined() to test if the
preprocessor define exists.
