When the system reset interrupt (0x100 trap) calls die(), it does not

so it continues on and ends up going BUG later.
Change the 0x100 logic in die to just avoid kexec/fadump. Then a 0

module_alloc() first tries to allocate module text within
24 bits direct jump from kernel text, and tries a wider

When first allocation fails the following is observed in kernel logs:
