I was hoping that we will pass the value returned by elfcorehdr_alloc()
here. Something along the lines of kmalloc() and kfree().
elfcorehdr_addr = elfcorhdr_alloc();
...
...
elfcorhdr_free(elfcorhdr_addr);
Only odd part here is that arch will not set elfcorehdr_addr=NULL as there
are functions like is_kdump_kernel() which depend on it being set.
That might be a separate cleanup thought and we can put a comment after
elfcorhdr_free() and explain that oddity.
Thanks
