Subject: [PATCH v1 0/2] KVM: arm64: Making BT Field in ID_AA64PFR1_EL1 writable
In this patch series, we try to make more register fields writable like
ID_AA64PFR1_EL1.BT since this can benifit the migration between some of the
machines which have different BT values.
Changelog:
----------
RFCv1 -> v1:
* Fix the compilation error.
* Delete the machine specific information and make the description more
generable.
