Why this change? The [PATCH RFC] armv7: fixloop: don't fixup if location is NULL
should be what you need.
You could mention what causes these NULL fixups, here is commit
entry for powerpc:
powerpc: do not fixup NULL ptrs
The fixup routine must not fixup NULL pointers.
Problem can be seen by
char *testfun(void) __attribute__((weak));
char *(*myfun)(void) = testfun;
Then add
printf("myfun:%p, &myfun:%p\n", myfun, &myfun);
before relocation and after relocation.
myfun should be NULL in both cases but it is not.
