[Dmitry Antipov]

This series should immediately follow v8 of lib and lib/cmdline enhancements,
see https://patchew.org/linux/20260212164413.889625-1-dmantipov@yandex.ru.
Started from riscv32 build quirk, now it aims to provide platform-specific
double-word shifts and corresponding KUnit test (tested on ARM as well).

Dmitry Antipov (2):
  riscv: add platform-specific double word shifts for riscv32
  lib: kunit: add tests for __ashldi3(), __ashrdi3(), and __lshrdi3()
