Hi,
This patch series implement support for dumping guest memory using qemu gdb
server. The last patch also enable qemu monitor command dump-guest-memory
With this patch series we can now do
(gdb) x/4i htab_call_hpte_insert1
0xc0000000000470d8 <.htab_call_hpte_insert1>: bl

NOTE: We still don't support inserting breakpoints.
Before Fix:
(qemu) memsave 0xc0000000000470d8 10 memdump
Invalid parameter 'addr'
(qemu)
After fix:
(qemu) memsave 0xc0000000000470d8 10 memdump
(qemu)
