exec.c: Fix off-by-one error in register_subpage
subpage_register() expects "end" to be the last byte in the mapping.
Registering a non-page-aligned memory region that extends up to or
beyond a page boundary causes subpage_register() to silently fail
through the (end >= PAGE_SIZE) check.
This bug does not cause noticeable problems for mappings that do not
extend to a page boundary, though they do register an extra byte.
