arch: uapi: asm: mman.h: Let MADV_FREE have same value for all architectures
Subsystems (7)
PATCH 1/1 arch: uapi: asm: mman.h: Let MADV_FREE have same value for all architectures
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...

Hello Maintainers:
After this patch, our parisc can pass allmodconfig in linux next tree, for me, we can say parisc specific code have no touch for allmodconfig. :-)
But for parisc gcc latest upstream compiler, I found several issues, and I shall try to analyse them and communicate with gcc related members.
And I also want to consult about parisc assembly instructions, I can not find the related reference documents, could you help to have a check (or provide some related information for it)? related contents are below:
parisc support several store instructions: 'stb' (for store byte), 'stw(m)' (for store word), and 'std' (for store double word).
They should be in the same format in binary code, and have neighbour numbers, and 'stw(m)' need be in the middle of 'stb' and 'std'. one sample for the instruction 'inst' (it is 'unsigned int'):
- for ((inst >> 26) != 0x3):
stb: 0x18, or 0x19,
stw: 0x1a, stwm: 0x1b,
std: 0x1c. - else ((inst >> 26) == 0x3), need check '(inst >> 6) & 0xf':
stb: 0x08, or 0x09,
stw: 0x0a,
std: 0x0b.it is about my binutils/gdb patch for parisc, gdb want to recognize 'st??' to find the position for saving relate context (registers).
Welcome any suggestions, ideas, and completions.
Thanks.

OK, thank you very much!!
For me, these information is enough, I checked the related sub link, it has a full description for all related instruction (stb/h, stw, std).
https://parisc.wiki.kernel.org/images-parisc/7/73/Parisc2.0.pdf
For me, my original comments need be improved: need mention about STH, and maybe also need consider about additional related instructions of parisc 2.0 (STDA, STWA, STBY, STDBY).
Thanks.

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.

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

Hello Chen,
Quoted 5 lines · Chen Gang
For uapi, need try to let all macros have same value, and
MADV_FREEis added into main branch recently, so need redefineMADV_FREEfor it.At present, '8' can be shared with all architectures, so redefine it to '8'.

Recently, I cleaned
MADV_FREEpatchset 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?
For me, it is OK. And thank you for your work. :-)
