Subject: [stable:PATCH v4.9.309 19/43] arm64: Make ARM64_ERRATUM_1188873 depend on COMPAT

From: Marc Zyngier <marc.zyngier@....com>

commit c2b5bba3967a000764e9148e6f020d776b7ecd82 upstream.

Since ARM64_ERRATUM_1188873 only affects AArch32 EL0, it makes some
sense that it should depend on COMPAT.
