[Crash-utility] ARM: crash registers might be read from the wrong physical address

Hi Dave I found a problem in arm.c that arm_get_crash_notes() is called too early. This has never been a problem until now. arm_get_crash_notes() in arm.c calls readmem(, KVADDR, ) which calls kvtop() which calls machdep->kvtop that is arm_kvtop which uses vt->vmalloc_start vt->vmalloc_start is initialized in vm_init machdep_init(POST_GDB); vm_init(); machdep_init(POST_VM); arm_get_crash_notes() is currently called in the POST_GDB section of machdep_init, but should be moved to the POST_VM section. I put the comment and the code just before: if (init_unwind_tables()) { and then it works fine. Without this fix the crash registers might be read from the wrong physical address.
