That is what they are used for. Lets make it more clear.
Of all the various sub-commands, the only one that needed
semantic change is XEN_SYSCTL_TMEM_OP_SAVE_BEGIN. That in the
past used 'arg1', and now we are moving it to use 'arg'.
Since that code is only used during migration which is tied
to the toolstack it is OK to change it.
We should increment the XEN_SYSCTL_INTERFACE_VERSION because
of this, and that was fortunatly done in the patch titled:
"tmem/libxc: Squash XEN_SYSCTL_TMEM_OP_[SET|SAVE].."
While at it, also fix xc_tmem_control_oid to properly handle
the 'buf' and bounce it as appropiate.

Specifically:
XEN_SYSCTL_TMEM_OP_SET_[WEIGHT,COMPRESS] are now done via:
XEN_SYSCTL_TMEM_SET_CLIENT_INFO
and XEN_SYSCTL_TMEM_OP_SAVE_GET_[VERSION,MAXPOOLS,
CLIENT_WEIGHT, CLIENT_FLAGS] can now be retrieved via:
XEN_SYSCTL_TMEM_GET_CLIENT_INFO
All this information is now in 'struct xen_tmem_client' and
that is what we pass around.
We also rev up the XEN_SYSCTL_INTERFACE_VERSION as we are
re-using the value number of the deleted ones (and henceforth
the information is retrieved differently).
On the toolstack, prior to this patch, the xc_tmem_control
would use the bounce buffer only when arg1 was set and the cmd
was to list. With the 'XEN_SYSCTL_TMEM_OP_SET_[WEIGHT|COMPRESS]'
that made sense as the 'arg1' would have the value. However
for the other ones (say XEN_SYSCTL_TMEM_OP_SAVE_GET_POOL_UUID)
the 'arg1' would be the length of the 'buf'. If this
confusing don't despair, patch patch titled:
tmem/xc_tmem_control: Rename 'arg1' to 'len' and 'arg2' to arg.
takes care of that.
The acute reader of the toolstack code will discover that
we only used the bounce buffer for LIST, not for any other
subcommands that used 'buf'!?! Which means that the contents
of 'buf' would never be copied back to the calleer 'buf'!
The author is not sure how this could possibly work, perhaps Xen 4.1
(when this was introduced) was more relaxed about the bounce buffer
being enabled. Anyhow this fixes xc_tmem_control to do it for
any subcommand that has 'arg1'.
Lastly some of the checks in xc_tmem_[restore|save] are removed
as they can't ever be reached (not even sure how they could
have been reached in the original submission). One of them
is the check for the weight against -1 when in fact the
hypervisor would never have provided that value.
Now the checks are simple - as the hypercall always returns
->version and ->maxpools (which is mirroring how it was done
prior to this patch). But if one wants to check the if a guest
has any tmem activity then the patch titled
"tmem: Batch and squash XEN_SYSCTL_TMEM_OP_SAVE_GET_POOL_
[FLAGS,NPAGES,UUID] in one sub-call: XEN_SYSCTL_TMEM_OP_GET_POOLS."
adds an ->nr_pools to check for that.
Also we add the check for ->version and ->maxpools and remove
the TODO.

The operations are to be used by an control domain to set parameters,
list pools, clients, and to be used during migration.
There is no need to have them in the tmem hypercall path.
This patch moves code without adding fixes - and in fact in
some cases makes the parameters soo long that they hurt eyes - but
that is for another patch.
Note that in regards to existing users:
- Only the control domain could call it - which meant that if
a guest called it would get -EPERM, so we are OK there.
In practice no guests called this TMEM_CONTROL command.
- The spec: https://oss.oracle.com/projects/tmem/dist/documentation/api/tmemspec-v001.pdf
mentions: "TBD [Not sure if this is really needed.]"
which is a carte blanche as any to do this!
Note: The XSM check is the same - we just move it from do_tmem_op
to do_sysctl.
We also add an 32-bit pad to make the sysctl structure have the same
exact size under 32 and 64-bit toolstacks and not worry about aligment
issues.

The error handling from a failed memory allocation should return
PyErr_SetFromErrno(xc_error_obj); rather than simply calling it and continuing
to the memcpy() below, with the dest pointer being NULL.
Coverity also complains about passing a non-NUL terminated string to
xc_flask_context_to_sid(). xc_flask_context_to_sid() doesn't actually take a
NUL terminated string, but it does take a char* which, in context, used to be
a string, which is why Coverity complains.
One solution would be to use strdup(ctx) which is simpler than a
strlen()/malloc()/memcpy() combo, which would result in a NUL-terminated
string being used with xc_flask_context_to_sid().
However, ctx is strictly an input to the hypercall and is not mutated along
the way. Both these issues can be fixed, and the error logic simplified, by
not duplicating ctx in the first place.

In xc_vcpu_setaffinity(), the cpumaps are IN/OUT parameters,
