Hi,
In this new version a change was made in patch 8. Instead of changing
scounteren to target_ulong, change the current logic to honor the QEMU
env storage instead of the KVM reg size.
This will make QEMU the authority when deciding how to read/write the
CSRs in the env flags instead of KVM.
We're doing this change in patch 8 but it could also be squashed into
patch 4. If the code in patch 8 is good to go I don't oppose merging it
with patch 4 if desired.
No other changes made.
Patches missing acks/review: patch 8.
Changes from v3:
- patch 8:
- instead of widening scounteren, use the QEMU storage size instead of
KVM reg size when reading/writing KVM CSRs
