Fix build error: lib/crypto/chacha.c: In function chacha_permute: lib/crypto/chacha.c:65:1: warning: the frame size of 3384 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^

IMO this needs a better explanation of why not having the include leads to the above failure.

BR, Jani.

Sorry, i made a mistake. The error is as follows:

drivers/gpu/drm/i915/gt/intel_ggtt.c: In function ggtt_restore_mappings: drivers/gpu/drm/i915/gt/intel_ggtt.c:1239:3: error: implicit declaration of function wbinvd_on_all_cpus; did you mean wrmsr_on_cpus? [-Werror=implicit-function-declaration] wbinvd_on_all_cpus(); ^~~~~~~~~~~~~~~~~~ wrmsr_on_cpus

Thanks, Chen Zhou
