No, something like this:

static int init_tdx_module(void)
{
static struct tdsysinfo_struct tdx_sysinfo; /* too rotund for the stack */
...
tdx_get_sysinfo(&tdx_sysinfo, ...);
...

But, also, seriously, 3k on the stack is *fine* if you can shut up the
warnings. This isn't going to be a deep call stack to begin with.
