The original message has been attached to this so you can view it or label similar future email. If you have any questions, see the administrator of that system for details. Content preview: From: Mike Rapoport <rppt@linux.ibm.com> free_p2m_page() wrongly passes a virtual pointer to memblock_free() that treats it as a physical address. Call memblock_free_ptr() instead that gets a virtual address to free the memory.
