[PATCH v7 23/28] x86_64/asm: change all ENTRY+END to SYM_CODE_*

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Here, we change all assembly code which is marked using END (and not
ENDPROC). We switch all these to appropriate new markings SYM_CODE_START
and SYM_CODE_END.
