We make proper use of SYM_DATA on global data instead of marking them as ENTRY. ENTRY is intended for functions and shall be paired with ENDPROC. ENTRY also aligns symbols which creates unnecessary holes here between data.
ENTRY from saved_eip in wakeup_32 and many saved_* in wakeup_64 is simply dropped, as these symbols are local only. Signed-off-by: Jiri Slaby <[email protected]> Cc: "Rafael J.
