Subject: [PATCH 0/2] KVM: selftests: arm64: Make use of sysreg defintions
 in get-reg-list

The system register definitions in the arm64 get-reg-list are all done
with directly specified magic numbers rather than using the definitions
we import from the main kernel.  This is error prone, and requires us to
audit the additions to get-reg-list separately to what we do when
specifying the registers for the main kernel.  Since Marc has indicated
that this isn't a deliberate or desired choice let's start using the
constants we have defined.

We first manually update the data used to filter registers based on ID
register fields to use a simplified macro that specifies the register
and ID field in a muc more compact fashion.  This is done first since
there is an error in the ID register field for the S1PIE registers.  We
then replace all the remaining named system register specifications with
use of the existing KVM_ARM64_SYS_REG() macro.
