Patch series "lib and lib/cmdline enhancements", v11. This series is a merge of the recently posted [1] and [2]. The first one is intended to adjust '_parse_integer_limit()' and 'memparse()' to not ignore overflows, extend string to 64-bit integer conversion tests, add KUnit-based test for 'memparse()' and fix kernel-doc glitches found in lib/cmdline.c. The second one was originated from RISCV-specific build fixes needed to integrate the former and now aims to provide platform-specific double-word shifts and corresponding KUnit test. Getting feedback from RISCV core maintainers would be very helpful. Special thanks to Andy Shevchenko, Charlie Jenkins, and Andrew Morton. This patch (of 8): In '_parse_integer_limit()', adjust native integer arithmetic with near-to-overflow branch where 'check_mul_overflow()' and 'check_add_overflow()' are used to check whether an intermediate result goes out of range, and denote such a case with ULLONG_MAX, thus making the function more similar to standard C library's 'strtoull()'. Adjust comment to kernel-doc style as well.
