Subject[PATCH v2] arm64: armv8_deprecated: fix unused-function error
Date
If CONFIG_SWP_EMULATION is not set and
CONFIG_CP15_BARRIER_EMULATION is not set,
aarch64-linux-gnu complained about unused-function :

arch/arm64/kernel/armv8_deprecated.c:67:21: error: ‘aarch32_check_condition’ defined but not used [-Werror=unused-function]
static unsigned int aarch32_check_condition(u32 opcode, u32 psr)
^~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

To fix this warning, modify aarch32_check_condition() with __maybe_unused.

Fixes: 0c5f416219da ("arm64: armv8_deprecated: move aarch32 helper earlier")
