Hi Borisslav,
My sincere apologies for it.
We actually tested the patch but I made a bad mistake while generating
the patch file to email.
I will send a PATCH V2 after testing the email version patch file from
the scratch.
Regards,
Wooky

Don't assume dest/source buffers are userspace addresses when manually
copying data for string I/O or MOVS MMIO, as {get,put}_user() will fail
if handed a kernel address and ultimately lead to a kernel panic.
