Ok, the trimmed backports:
- removed the patch which touched common code w/out #ifdef blocks.
- now all changes are under #ifdef blocks, which helps analysis.
Build log:
...
ALL TESTS SUCCESSFUL.
make[2]: Leaving directory '/home/ubuntu/ss5/openssl-1.0.1f/test'
...
In the patches, all changes are under these macros; now, checking for their
definitions will identify if any other arches might be affected.
1)
#ifdef HWAES_CAPABLE
#ifdef HWAES_cbc_encrypt
#ifdef HWAES_ctr32_encrypt_blocks
2)
#if ... && (... || defined(OPENSSL_CPUID_OBJ))
3)
#ifdef HWAES_CAPABLE
#ifdef HWAES_ctr32_encrypt_blocks
