Here's the latest version of the patches:

John,
the first of the patches implements the approach that we previously discussed.
All arguments are passed starting at a fixed offset that should provide enough
space for extending argument list. The first of the extended arguments should
be
a size of the arguments (including the size field). Then it's easy to write
something like:
struct xargs
{
uint32_t size;
...
};
...
struct xargs xargs;
xargs.size = sizeof(xargs);
...
__exec(..., xargs);
Marius, Gavin,
patch 1f94d9a is my attempt of adapting your sparc64 ZFS code to my larger
changes
in patch ae5a9c6. I have the patches separate to facilitate the review. They
should be committed together. I have only compile-tested the sparc64/ofw part,
so
it could have some grave bugs or omissions.
Could you please review and/or test this patch?
I will greatly appreciate any discussion, suggestions, help.
I again invite everyone else to take part in the review and testing.
