Hi
Currently, there is no overflow-check with memdup_user().
Use the new function memdup_array_user() instead of memdup_user() for
duplicating the user-space array safely.

Hi!
David Airlie suggested that we could implement new wrappers around
(v)memdup_user() for duplicating user arrays.
This small patch series first implements the two new wrapper functions
memdup_array_user() and vmemdup_array_user(). They calculate the
array-sizes safely, i.e., they return an
Currently, user array duplications are sometimes done without an
overflow check. Sometimes the checks are done manually; sometimes the
array size is calculated with array_size() and sometimes by calculating
n * size directly in code.
Introduce wrappers for arrays for memdup_user() and

While the manpage does mention about kexec boot with a clean shutdown,
it is not explicit about it. Make it explicit.

In my mind the big question is how to move RISC-V support
from that branch, to being merged into
