Hello Dave,
Could you confirm it?

I don't understand what you want me to confirm.

Sorry for lacking of the information.

Is it okay to use number 8 for upcoming madvise(addr, len, MADV_FREE)
feature in sparc arch?

The reason to ask is that Darrick pointed out earlier that
dietlibc has a Solaris #define MADV_FREE 0x5 in its mman.h
and Hugh pointed out that was in the kernel's sparc mman.h up
until 2.6.25 but disappeared now so I guess it's okay to use the
number 8 for MADV_FREE in sparc but want to confirm from you.

Thanks.
