xmalloc: make whole pages xfree() clear the order field (ab)used by xmalloc()
|
|
|
|
Not doing this was found to cause problems with sequences of allocation
|
|
(multi-page), freeing, and then again allocation of the same page upon
|
|
boot when interrupts are still disabled (causing the owner field to be
|
|
non-zero, thus making the allocator attempt a TLB flush and, in its
|
|
processing, triggering an assertion).
