This is slightly complicated. Patches 1 and 2 rearrange the code to look and
behave more like 4.14, and patch 3 fixes a Solaris (and turbostat) bug in a
manner which can be backported to all security trees.
Andrew Cooper (3):
Revert "x86/msr: drop compatibility #GP handling in guest_{rd,wr}msr()"
x86/msr: Forward port XSA-351 changes from 4.14
x86/msr: Fix Solaris and turbostat following XSA-351
