Prime numbers are interesting for testing components that use multiplies
and divides, such as testing DRM's struct drm_mm alignment computations.
v2: Move to lib/, add selftest
v3: Fix initial constants (exclude 0/1 from being primes)
v4: More RCU markup to keep 0day/sparse happy
v5: Fix RCU unwind on module exit, add to kselftests
v6: Tidy computation of bitmap size
v7: for_each_prime_number_from()
v8: Compose small-primes using BIT() for easier verification
v9: Move rcu dance entirely into callers.
v10: Improve quote for Betrand's Postulate (aka Chebyshev's theorem)

Test for test_printf module fails always because the test program,
printf.sh, has no execution permission. This commit adds execution
permission to it.

This is mainly testing bitmap construction and conversion to/from u32[]
for now.
Tested:
qemu i386, x86_64, ppc, ppc64 BE and LE, ARM.

This runs the lib/test_printf module to make sure printf is operating
sanely.
