[stable:PATCH v4.9.309 19/43] arm64: Make ARM64_ERRATUM_1188873 depend on COMPAT
From: James Morse
Date: Wed Apr 06 2022 - 14:07:44 EST
From: Marc Zyngier <marc.zyngier@xxxxxxx>
commit c2b5bba3967a000764e9148e6f020d776b7ecd82 upstream.
Since ARM64_ERRATUM_1188873 only affects AArch32 EL0, it makes some
sense that it should depend on COMPAT.
