 Modified Files:
        src/sys/arch/sparc/sparc: auxreg.h
 
 Log Message:
 Explicitly clear AUXIO4M_FTC bit in FTC_FLIP macro used on
 pseudo-dma for floppy, as well as AUXIO4C_FTC bit for sun4c.
 A comment in the macro says AUXIO4M_FTC bit is auto-clear,
 but my two SS20s (including compatible) with 150MHz hyperSPARCs
 get data_overrun without it, and no bad side effect on SS5
 (works with and without this change).
 
 Closes PR port-sparc/42516, which is the last one of a bunch of
 floppy issue on NetBSD/sparc since NetBSD 2.0 days. See
 http://mail-index.NetBSD.org/port-sparc/2009/12/20/msg000484.html
 for details.
