Hi, Pasha

I noticed that you are moving kexec_handover.c from the kernel/ directory to kernel/liveupdate/.

Several developers suggested that I resend my patch after your patch series is merged upstream.
Therefore, I=E2=80=99d like to ask if you could include my patch in y= our series. This would help avoid extra work on my side to resend the commit later.

Thanks,

Yanjun.Zhu

Make pr_xxx() call to use the %pe format specifier instead of =
%d.
The %pe specifier prints a symbolic error string (e.g., -ENOMEM,
-EINVAL) when given an error pointer created with ERR_PTR(err).

This change enhances the clarity and diagnostic value of the error
message by showing a descriptive error name rather than a numeric
error code.

Thanks,

This looks good to me, even though I note that this file
has moved in linux-next.
