8143254f9b support remove static variables using KPATCH_IGNORE_STATIC 
Static variables will be removed due to compiler optimization.
And some static variables can be treated as new variables, such as
static variables in print limit macros. So add KPATCH_IGNORE_STATIC
to tell kpatch to treat the static variables as new variables.
