Hi,
as I was doing some clean-ups in the bootmem allocator, I noticed the
patch
5a982cbc7b3fe6cf72266f319286f29963c71b9e
mm: fix boundary checking in free_bootmem_core
which seems to implement the opposite of what the subject promises.
It makes input arguments acceptable if they are `a bit wrong' and
silently aborts if they are completely off the whack.
Please have a look at the two patches I propose: one to revert the
original and the other one to reimplement what the whole thing was
really about: having free_bootmem() itself look up the node holding
the specified address range.
Note also that the reverted patch changed a helper function and
therefore also affected free_bootmem_node(), making the latter paper
over bugs as well.
Hannes
