Shouldn't you put the include files needed for all that in there too?

Otherwise you have another ugly list to duplicate. The includes
cannot be put inside the ioctl list, because in some extreme 
case they can generate code (e.g. when gcc decides to ignore inline
again and emits functions for includes)

It could be done with a special symbol like:

#ifdef DO_INCLUDES
#include foo1
#include foo2
#else
COMPATIBLE_IOCTL(...)
#endif

List of includes is *way* shorter than 600 lines of
COMPATIBLE_IOCTL. I prefer to keep it simple for now.

I disagree. The big issue with the duplicated code is not how long it
is, but that it needs N changesets to fix something instead of one.
Typically a new ioctl also adds a new include.
If you keep the includes separated it'll have even more mainteance
overhead than before (you need N+1 commits to add the new ioctl)

Well, there are two of them... 600 lines of duplicated code is great
for differences starting to creep in...

Okay, I'll think what to do with it.

Okay, I was carefull this time to only include common set. (I still
think that most differences are simple bugs).

The only issue I'm aware of are structures with long long. IA64 and
x86-64 are special in that long long has a different alignmnet in 32bit
and 64bit (4 bytes in 32bit, 8 bytes in 64bit). All the other archs with
compat code have always 8 byte alignment. This means if sparc64 doesn't
do a conversion, but x86-64 does you cannot put it into the COMPAT_IOCTL
list. Make sure you only use the common set.

Fortunately long long is not that common and many uses of it are already
8 byte aligned, but not all are.

include/linux/compat_ioctl.h can be renamed to fs/compat_ioctl.c if
people prefer. I do not know which one is better.

I'm trying to be carefull. How common are ioctls that are
COMPATIBLE_IOCTL(foo) on one arch, but not on another? So far I tried
to decide, and mostly decided that one architecture was simply
missing...

Well, if I'm a little more carefull, all I will change will be order
of fields in that ioctl32_start table. Should I aim for that?

If this is just about HANDLE_IOCTL, IOCTL_TABLE_START etc., they look 
trivial enough to be put in asm/compat.h. They even appear to be
arch independent even though they have inline asm.

Ah, I have always wondered why it is done in such a strange way for some
architectures.

This would work for COMPATIBLE_IOCTLS, but the conversions handlers
would need a new asm/ file for the macros. They're declared with assembler
magic to avoid declaring all the functions. This way you need less files.

Why not simply move the common COMPATIBLE_IOCTLs and includes into
kernel/compat_ioctl.c or similar? That would IMHO be cleaner and
it does not need more preprocessing hacks.
There can still be a second init_sys32_ioctl() copy to handle the arch
specific list with additional translations.

   This patche moves common COMPATIBLE_IOCTLs to
   include/linux/compat_ioctl.h, enabling pretty nice cleanups:

Please be careful.  For anything non-trivial there can be major
differences between compat layers.

I say this now because eventually I want this compat stuff
to support multiple-compilations, using some COMPAT_NAME(foo)
macro scheme and some Makefile hackery.

This would allow, for example, x86_64 to have an x86_32 and
x86_32_sysv compat layer in one build.  So for example in this case
fs/compat.c would be built twice, once with x86_32 compat types
and once with x86_32_sysv types.
