Hi stable maintainers,
This is a backport patch for commit df205b5c6328 ("KVM: arm64: Filter
out invalid core register IDs in KVM_GET_REG_LIST") to 4.14 and 4.19.
This commit was not applied to the 4.14-stable tree due to merge
conflict [1]. To backport this, cherry-picked commit be25bbb392fa
("KVM: arm64: Factor out core register ID enumeration") that has no
functional changes but makes it easy to merge, and commit 5d8d4af24460
("arm64: KVM: Fix system register enumeration") that is a fix patch for
the commit.
I'd appreciate it if you could consider backporting this to 4.14 and
4.19.
Best regards,
Takahiro
