Hi All, Here is a patch series refactoring the current 2 separate SHA256 C implementations into 1 and put it into a separate library. There are 2 reasons for this: 1) Remove the code duplication of having 2 separate implementations 2) Offer a separate library SHA256 implementation which can be used without having to call crypto_alloc_shash first. This is especially useful for use during early boot when crypto_alloc_shash does not work yet. This has been tested on x86, including checking that kecec still works. This has NOT been tested on s390, if someone with access to s390 can test that things still build with this series applied and that kexec still works, that would be great. Regards, Hans
