[PATCH] crypto: Use ___cacheline_aligned for aes data

From: Andi Kleen cacheline_aligned is a special section. It cannot be const at the same time because it's not read-only. It doesn't give any MMU protection. Mark it cacheline_aligned to not place it in a special section, but just align it in .rodata Cc: herb...@gondor.apana.org.au Suggested

[PATCH 1/2] crypto: scompress: return proper error code for allocation failure

If scomp_acomp_comp_decomp() fails to allocate memory for the destination then we never copy back the data we compressed. It is probably best to return an error code instead 0 in case of failure. I haven't found any user that is using acomp_request_set_params() without the `dst' buffer so there is

[PATCH 2/2] crypto: scompress: Use per-CPU struct instead multiple variables

Two per-CPU variables are allocated as pointer to per-CPU memory which then are used as scratch buffers. We could be smart about this and use instead a per-CPU struct which contains the pointers already and then we need to allocate just the scratch buffers. Add a lock to the struct. By doing so we
