Same thing here, I would rewrite it as:

CACHE_MODE_1 register should be saved and restored as part of
the context, not during engine reset. Move the related workaround
from rcs_engine_wa_init() to gen7_ctx_workarounds_init() for
Gen7 platforms. This ensures the WA is applied during context
initialisation.
