2018-09-25crypto: rename DEBUG to SELFTESTJason A. Donenfeld
Also we make selftest errors of type err, so that they're obvious in dmesg. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-09-23chacha20-arm: use new scalar implementationJason A. Donenfeld
It turns out this is faster than NEON on some chips, so it's nice to have. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-09-21chacha20-mips32r2: use simpler calling conventionJason A. Donenfeld
Since we now set up the block in the generic code, we can rely on that to use fewer variables and reduce stack pressure within the MIPS code. This in turn means we have more registers and more uniformity, so we're able to rewrite quite a bit. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-21chacha20-arm: go with Ard's version to optimize for Cortex-A7Jason A. Donenfeld

2018-09-21chacha20-mips32r2: remove reorder directivesRené van Dorst
This requires some minimal rearranging to make work, but for the most part as does the right thing, provided we pass it an optimization flag. Suggested-by: Paul Burton <paul.burton@mips.com> Signed-off-by: René van Dorst <opensource@vdorst.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-09-20global: put SPDX identifier on its own lineJason A. Donenfeld
The kernel has very specific rules correlating file type with comment type, and also SPDX identifiers can't be merged with other comments. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-09-18chacha20: add independent self testJason A. Donenfeld
This was already tested from the chacha20poly1305 test, but it's useful to be able to test this in isolation too. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
