Hi,

Many architectures implement free_initmem() in exactly the same or very
similar way: they wrap the call to free_initmem_default() with sometimes
different 'poison' parameter.

These patches switch those architectures to use a generic implementation
that does free_initmem_default(POISON_FREE_INITMEM).

This was inspired by Christoph's patches for free_initrd_mem [1] and I
shamelessly copied changelog entries from his patches :)

v2: rebased on top of v5.0-rc7 + Christoph's patches for free_initrd_mem

  init: provide a generic free_initmem implementation
  hexagon: switch over to generic free_initmem()
  init: free_initmem: poison freed init memory
  riscv: switch over to generic free_initmem()
