crypto: sm4 - Do not change section of ck and sbox
[ Upstream commit 4a7e1e5fc294687a8941fa3eeb4a7e8539ca5e2f ]
When building with clang and GNU as, there is a warning about ignored
changed section attributes:
/tmp/sm4-c916c8.s: Assembler messages:
/tmp/sm4-c916c8.s:677: Warning: ignoring changed section attributes for
.data..cacheline_aligned
"static const" places the data in .rodata but __cacheline_aligned has
the section attribute to place it in .data..cacheline_aligned, in
addition to the aligned attribute.
To keep the alignment but avoid attempting to change sections, use the
____cacheline_aligned attribute, which is just the aligned attribute.
Fixes: 2b31277af577 ("crypto: sm4 - create SM4 library based on sm4 generic code")
