x86/msr: Add a pointer to an URL which contains further details (2020-12-08 10:17:08 +0100)

----------------------------------------------------------------
The main part of this branch is the ongoing fight against windmills in
an attempt to have userspace tools not poke at naked MSRs. This round
deals with MSR_IA32_ENERGY_PERF_BIAS and removes direct poking into it
by our in-tree tools in favor of the proper "energy_perf_bias" sysfs
interface which we already have.

In addition, the msr.ko write filtering's error message points to a new
summary page which contains the info we collected from helpful reporters
about which userspace tools write MSRs:

https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/about

along with the current status of their conversion.

Rest is the usual small fixes and improvements.
