Done, but the sequence of patches is reordered at ARM patch system, 
(using git send-email

and deliver patch1/2/3 in order).

BTW,  could you give me some direction the following patchset[1] too if 
you have time, I have

addressed your comments and resend, but there's been no new feedback for 
a long time.

If it is too late for this cycle, I could resend them after 5.15-rc1.

Many thanks.
