Subject: fix bloat-o-meter for ppc64
From: Nathan Lynch <ntl@xxxxxxxxx>
bloat-o-meter assumes that a '.' anywhere in a symbol's name means that it
is static and prepends 'static.' to the first part of the symbol name,
discarding the portion of the name that follows the '.'. However, the
names of function entry points begin with '.' in the ppc64 ABI. This
causes all function text size changes to be accounted to a single 'static.'
entry in the output when comparing ppc64 kernels.
Change getsizes() to ignore the first character of the symbol name when
searching for '.'.
