Subject: page-flags: rectify forward declaration
compound_head is defined as inline in page-flags.h but in the forward
declaration of compound_head in the same file missed "inline". As a
result we got plenty of build warnings while building for some
architecture like avr32. The warning showed as: warning: 'compound_head'
declared inline after being called. warning: previous declaration of
'compound_head' was here
