For uapi, need try to let all macros have same value, and MADV_FREE is
added into main branch recently, so need redefine MADV_FREE for it.
At present, '8' can be shared with all architectures, so redefine it to
'8'.

Hmmm... you might want to talk to the dietlibc people if you do this:
$ grep -rn MADV_FREE /usr/include/
/usr/include/diet/sys/mman.h:101:#define MADV_FREE 0x5 /* (Solaris) contents can be freed */
Though the sole definition only exists on sparc/powerpc/powerpc64, so who
knows...

Excuse me, I am not quite familiar about dietlibc. If possible, please
help forward this mail to them, and Cc me (if necessary).

OK, thanks.
Originally I sent the same patch like you sent (but later than yours).
Geert suggested to use same value for MADV_FREE, and Carlos confirmed
it and suggested more things (sorry, I forgot to Cc them in this mail).
Thanks.

Hello dietlibc members:
When I sent a Linux kernel patch for uapi, some members suggest me to
Cc dietlibc members, so I forward the related mail to dietlibc mailing
list.
Please check, and welcome any ideas, suggestions, or completions.
Thanks.

For uapi, need try to let all macros have same value, and MADV_FREE is
added into main branch recently, so need redefine MADV_FREE for it.
At present, '8' can be shared with all architectures, so redefine it to
'8'.

Hello dietlibc members:
When I sent a Linux kernel patch for uapi, some members suggest me to
Cc dietlibc members, so I forward the related mail to dietlibc mailing
list.
Please check, and welcome any ideas, suggestions, or completions.
Thanks.

For uapi, need try to let all macros have same value, and MADV_FREE is
added into main branch recently, so need redefine MADV_FREE for it.
At present, '8' can be shared with all architectures, so redefine it to
'8'.

Hello Andrew:
Could you help check this patch, when you have time. And apply it if
possible.
I guess, this patch is a little urgent, since it changes uapi, if wait
a little longer, more user mode programs (e.g. libc) may use MADV_FREE
as various values.
Thanks.

Recently, I cleaned MADV_FREE patchset up and will send uptodate version
to Andrew to replace old implementation in mmotm tree which is not a
linus's tree so this change shouldn't break anyting.
When I look at status of this patch, it seems Andrew missed it
so I want to include this patch when I respin if you don't mind.
Is it okay for you?
Thanks.
