Hi, The problem is that mmaping a segment <addr,len> from /dev/kmem gives differnet results than reading the same <addr,len>. It seems that the bug is that mmap_kmem is a macro for mmap_mem (for /dev/mem). mmap_mem maps a _physical_ offset into a vm area vma, while mmap_kmem should map a _virtual_ offset into a vm area. I hacked it to work by copying mmap_mem to mmap_kmem and adding __pa() in the proper assginment, but I don't know how to check if the offset is valid in the kernel virtual memory. Maybe someone who knows the mm code better can fix this?
