[PATCH 0/1] crypto: arm64/aes-neonbs - Move key expansion off the stack

[Cheng-Yang Chou]

aesbs_setkey() and aesbs_cbc_ctr_setkey() trigger -Wframe-larger-than=
warnings because struct crypto_aes_ctx is allocated on the stack,
pushing the frame size to ~1040 bytes and exceeding the 1024-byte limit.

arch/arm64/crypto/aes-neonbs-glue.c: In function ‘aesbs_setkey’:
arch/arm64/crypto/aes-neonbs-glue.c:92:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=]
   92 | }
      | ^
arch/arm64/crypto/aes-neonbs-glue.c: In function ‘aesbs_cbc_ctr_setkey’:
arch/arm64/crypto/aes-neonbs-glue.c:152:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=]
  152 | }
      | ^

Tested on arm64. Confirmed the -Wframe-larger-than= warning is resolved.

Thanks,
Cheng-Yang
