It's always been the better solution anyway, and\nit's much more efficient if properly optimized code is used.\n\nThus, drop the PowerPC optimized MD5 code. Note that this code contains\nno privileged instructions and could be run in userspace just fine.\n\nMD5 is still supported, just with the generic code only. I.e., this\ncommit only changes performance; it isn't a hard break.\n\nThis also has no effect on implementations of md5sum that already just\nuse userspace code (as they should), for example the coreutils one.\n\nSigned-off-by: Eric Biggers <ebiggers@kernel.org>\n---\n lib/crypto/Kconfig | 5 -\n lib/crypto/Makefile | 4 -\n lib/crypto/md5.c | 20 ++-\n lib/crypto/powerpc/md5-asm.S | 235 -----------------------------------\n lib/crypto/powerpc/md5.h | 12 --\n 5 files changed, 7 insertions(+), 269 deletions(-)\n delete mode 100644 lib/crypto/powerpc/md5-asm.S\n delete mode 100644 lib/crypto/powerpc/md5.h\n\n\nbase-commit: 7fd2df204f342fc17d1a0bfcd474b24232fb0f32", "diff": "diff --git a/lib/crypto/Kconfig b/lib/crypto/Kconfig\nindex d3904b72dae7..591c1c2a7fb3 100644\n--- a/lib/crypto/Kconfig\n+++ b/lib/crypto/Kconfig\n@@ -129,15 +129,10 @@ config CRYPTO_LIB_MD5\n \ttristate\n \thelp\n \t The MD5 and HMAC-MD5 library functions.
