Hi,

While implementing a binary format loader for a foreign executable format, we have found the need to setup the user stack starting at (virtual) address 0xE0000000 instead of the usual 0xC0000000. However a call to setup_arg_pages() with that value returns -EINVAL.

Is there any way to setup the stack such that it starts at 0xE0000000 and grows downwards?

Regards,
Anant
