Subject: [PATCH v10 0/3] ARMv8.5-RNG support
Date: Fri, 10 Jan 2020 12:23:38 +0000	[thread overview]
Message-ID: <20200110122341.8445-1-broonie@kernel.org> (raw)

This series is based on Richard Henderson's previous v7, it addresses
review comments from that version by splitting the boot and runtime
interaction with the core random code so that they are completely
separate and adds a new change that uses the v8.5-RNG extension to seed
KASLR when ARCH_RANDOM is enabled.

v10:
 - Spell out that we're adding data not entropy from setup_arch() in
   the commit message for patch 2.
v9:
 - Make another static inline helper for early feature checks.
 - Add init annotations.
 - Use xor to add RNDR output to seed for KASLR.

Mark Brown (2):
  arm64: random: Add data to pool from setup_arch()
  arm64: Use v8.5-RNG entropy for KASLR seed

Richard Henderson (1):
  arm64: Implement archrandom.h for ARMv8.5-RNG
