[Mesa-dev] [PATCH v2 1/5] util/hash_table: Fix hashing in clears on 32-bit

Some hash functions (eg. key_u64_hash) will attempt to dereference the key, causing an invalid access when passed DELETED_KEY_VALUE (0x1) or FREED_KEY_VALUE (0x0). To avoid this problem, stuff the fake keys into a hash_key_u64 struct and pass the pointer to it instead. Signed-off-by: Tomeu Vizoso
