-Subject: [PATCH] i386: avoid null pointer dereference
-
-    Hello,
-
-A null pointer dereference issue was reported by Mr Ling Liu, CC'd here. It
-occurs while doing I/O port write operations via hmp interface. In that,
-'current_cpu' remains null as it is not called from cpu_exec loop, which
-results in the said issue.
-
-Below is a proposed (tested)patch to fix this issue; Does it look okay?
-
-===

-When I/O port write operation is called from hmp interface,
-'current_cpu' remains null, as it is not called from cpu_exec()
-loop. This leads to a null pointer dereference in vapic_write
-routine. Add check to avoid it.
