[PATCH v3 0/2] x86: RTC handling adjustments

[Jan Beulich <jbeulich@xxxxxxxx>]

The first patch addresses a recent regression and hence ought to be
considered for 4.14, despite it getting late. I noticed the problem
while re-basing the 2nd patch here, which I decided to now re-post
despite the original discussion on v1 not having lead to any clear
result (i.e. the supposed "leave Dom0 handle the RTC" has never
materialized over the past almost 5 years), while I still think
that the changed code is at least a little bit of improvement.

1: restore pv_rtc_handler() invocation
2: detect CMOS aliasing on ports other than 0x70/0x71
