Re: Widespread crashes in -next, bisected to 'mm: drop HASH_ADAPT'

The problem is due to 32-bit integer overflow in: ADAPT_SCALE_BASE and adapt In dcache_init_early() that is causing the problem. It was not enabled before 'mm: drop HASH_ADAPT' but is enabled now, and it should follow right after: "PID hash table entries: 1024 (order: 0, 4096 bytes)" main()
