Hello Qiao,

These are the changes I made to your patch:
       
 (1) display the dd->num_qemu_notes counter
 (2) adjusted the QEMUCPUState display functions for proper "line-up" depending
     upon whether the caller is ELF or compressed kdump.
 (3) realloc() the dd->nt_qemu_percpu and dd->nt_prstatus_percpu arrays from NR_CPUS-based
     to the actual number of notes. 
 (4) free() the dd->nt_qemu_percpu pointer array when it's not used.
 (5) renamed dump_nt_prstatus_offset() to dump_note_offsets(), and have it show 
     the dumpfile offsets for both note types. 

Queued for crash-7.1.0:
