Just to clarify, you'd add the extra arg at the end like this, right?
objdump-func <file> <func> -Mintel

Sure, I'll match ".whatever" if there's a period, but not other substring matches, e.g. "put_page" shouldn't match "put_pages_list".
{OBJDUMP} -wdr $@ $OBJ | gawk -M -v f=$FUNC '/^$/ { P=0; } $0 ~ "<" f "(\\..*)?>:" { P=1; O=strtonum("0x" $1); } { if (P) { o=strtonum("0x" $1); printf("%04x ", o-O); print $0; } }'
