Hello
Since next-20170428 the ARTPEC-6 SoC (MACH_ARTPEC6) does no longer boot. It works fine with next-20170427. I've bisected it to the following commit: 6d684e54690caef45cf14051ddeb7c71beeb681b is the first bad commit commit 6d684e54690caef45cf14051ddeb7c71beeb681b Author: Herbert Xu <[email protected]> Date: Thu Apr 27 13:44:51 2017 +0800 rhashtable: Cap total number of entries to 2^31 When max_size is not set or if it set to a sufficiently large value, the nelems counter can overflow. This would cause havoc with the automatic shrinking as it would then attempt to fit a huge number of entries into a tiny hash table. This patch fixes this by adding max_elems to struct rhashtable to cap the number of elements. This is set to 2^31 as nelems is not a precise count. This is sufficiently smaller than UINT_MAX that it should be safe. When max_size is set max_elems will be lowered to at most twice max_size as is the status quo.
