In commit 71052dcf4be70 ("crypto: scompress - Use per-CPU struct instead multiple variables") I accidentally initialized multiple times the memory on a random CPU. I should have initialize the memory on every CPU like it has been done earlier. I didn't notice this because the scheduler didn't move the task to another CPU. Guenter managed to do that and the code crashed as expected.Allocate / free per-CPU memory on each CPU.

Yes, it does. Tested-by: Guenter Roeck <[email protected]> Tested with the patch applied on top of next-20190412, running all 345 qemu boot tests. No boot failures or new warnings observed. To be sure, I ran the arm64 boot tests twice. Guenter
