The entropy generation function keeps a local cpu mask on the stack,
which can trigger warnings in configurations with a large number of
CPUs:
drivers/char/random.c:1292:20: error: stack frame size (1288)
exceeds limit (1280) in 'try_to_generate_entropy' [-Werror,-Wframe-larger-than]
Use the cpumask interface to dynamically allocate it in those
configurations.
Fixes: 1c21fe00eda7 ("random: spread out jitter callback to different CPUs")
