Listed in 2.4 headers as:
#define mem_map_reserve(p) set_bit(PG_reserved, &p->flags)
#define mem_map_unreserve(p) clear_bit(PG_reserved, &p->flags)
...but should be:
#define mem_map_reserve(p) set_bit(PG_reserved, &((p)->flags))
#define mem_map_unreserve(p) clear_bit(PG_reserved, &((p)->flags))
Because of the 'void *' nature of the 2nd parameter to set_bit/clear_bit,
the compiler is not picking up this error. Either expression generates
a pointer, but not the same values.
Might as well also wrap the parameter 'p' with parentheses in the
subsequent macros, mem_map_inc_count() and mem_map_dec_count(),
for clarity.
CC me if needed. I'm not on this list.
