arm64: Update silicon-errata.txt for Neoverse-N1 #1349291
Neoverse-N1 affected by #1349291 may report an Uncontained RAS Error as Unrecoverable. The kernel's architecture code already considers Unrecoverable errors as fatal as without kernel-first support no further error-handling is possible. Now that KVM attributes SError to the host/guest more precisely the host's architecture code will always handle host errors that become pending during world-switch. Errors misclassified by this errata that affected the guest will be re-injected to the guest as an implementation-defined SError, which can be uncontained. Until kernel-first support is implemented, no workaround is needed for this issue. Signed-off-by: James Morse <james.morse@arm.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
