[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v3 04/29] x86: assembly, use ENDPROC for functions
Somewhere END was used to end a function. It is not intended to be used
for functions, because it does not mark the actual symbols as functions.
Use ENDPROC in such cases which does the right job.
