[PATCH v2 00/11] introduce random32_get_bytes() and random32_get_bytes_state()

This patchset introduces new functions into random32 library for
getting the requested number of pseudo-random bytes.

Before introducing these new functions into random32 library,
prandom32() and prandom32_seed() with "prandom32" prefix are
renamed to random32_state() and srandom32_state() respectively.

The purpose of this renaming is to prevent some kernel developers
from assuming that prandom32() and random32() might imply that only
prandom32() was the one using a pseudo-random number generator by
prandom32's "p", and the result may be a very embarassing security


* v2
- rename prandom32 to random32_state
- dropped lib/uuid.c patch
- add bnx2 and mtd_stresstest patches

Akinobu Mita (11):
  random32: rename prandom32 to random32_state
  random32: introduce random32_get_bytes() and
  bnx2x: use random32_get_bytes()
  mtd: nandsim: use random32_get_bytes
  ubifs: use random32_get_bytes
  mtd: mtd_nandecctest: use random32_get_bytes instead of
  mtd: mtd_oobtest: convert to use random32_get_bytes_state()
  mtd: mtd_pagetest: convert to use random32_get_bytes_state()
  mtd: mtd_speedtest: use random32_get_bytes
  mtd: mtd_subpagetest: convert to use random32_get_bytes_state()
  mtd: mtd_stresstest: use random32_get_bytes()
