Since the commit in the title, a kernel built on an HP Mini 110 Netbook no
longer has keyboard input. The main difference is that CONFIG_SERIO_I8042 is no
longer defined. When this equal yes, the keyboard works. The faulty commit was
located by bisection and has been verified by reverting the patch.
Further investigation shows that the faulty hunk is

i8042 is the chip over which the standard AT keyboard and PS/2
mouse are connected to the computer. If you use these devices,
Reverting this one hunk alone results in a working system. Obviously, this
Netbook does not have X86_MRST set.

You meant to say "does have CONFIG_X86_MRST set", right?
Thanks.

Yes. I got lost in the negative logic. Since !X86_MRST is false, then X86_MRST
has to be defined. In fact, .config has CONFIG_X86_MRST=y.

Good. HPA posted a patch series that should fix the problem, in the mean
time just disable Moorestown support - you do not need it anyway.
