[PATCH v2 00/10] random: re-group and re-document functions

["Jason A. Donenfeld" <Jason@zx2c4.com>]

We previously had massive documentation comments and functions strewn
all about. This attempts to restore sanity by dividing the code into a
few sections:

- Initialization and readiness waiting.
- Fast key erasure RNG.
- Entropy accumulation and extraction.
- Entropy collection.
- Userspace read/write.
- Sysctl.

The result of this ordering and this grouping is only 2 forward
declarations, indicating that this is probably a sensible grouping.
Also, some documentation that was just hopelessly out of date been
removed. We'll later look into re-adding parts of this to the Linux man
pages project.

No functional changes.

Jason A. Donenfeld (10):
  random: introduce drain_entropy() helper to declutter crng_reseed()
  random: remove useless header comment
  random: remove whitespace and reorder includes
  random: group initialization wait functions
  random: group crng functions
  random: group entropy extraction functions
  random: group entropy collection functions
  random: group userspace read/write functions
  random: group sysctl functions
  random: rewrite header introductory comment
