2022-03-22Revert "random: block in /dev/urandom"Linus Torvalds
This reverts commit 6f98a4bfee72c22f50aedb39fb761567969865fe. It turns out we still can't do this. Way too many platforms that don't have any real source of randomness at boot and no jitter entropy because they don't even have a cycle counter. As reported by Guenter Roeck: "This causes a large number of qemu boot test failures for various architectures (arm, m68k, microblaze, sparc32, xtensa are the ones I observed). Common denominator is that boot hangs at 'Saving random seed:'" This isn't hugely unexpected - we tried it, it failed, so now we'll revert it.

2022-03-22bnx2x: truncate value to original sizingBill Wendling
The original behavior was to print out unsigned short or unsigned char values. The change in commit d65aea8e8298 ("bnx2x: use correct format characters") prints out the whole value if not truncated.

2022-03-21net: mdio: mscc-miim: add lan966x internal phy reset supportMichael Walle
The LAN966x has two internal PHYs which are in reset by default. The driver already supported the internal PHYs of the SparX-5. Now add support for the LAN966x, too. Add a new compatible to distinguish them. The LAN966x has additional control bits in this register, thus convert the regmap_write() to regmap_update_bits() to leave the remaining bits untouched. This doesn't change anything for the SparX-5 SoC, because there, the register consists only of reset bits.

2022-03-21net: dsa: mv88e6xxx: Fill in STU support for all supported chipsTobias Waldekranz
Some chips using the split VTU/STU design will not accept VTU entries who's SID points to an invalid STU entry. Therefore, mark all those chips with either the mv88e6352_g1_stu_* or mv88e6390_g1_stu_* ops as appropriate. Notably, chips for the Opal Plus (6085/6097) era seem to use a different implementation than those from Agate (6352) and onwards, even though their external interface is the same. The former happily accepts VTU entries referencing invalid STU entries, while the latter does not. This fixes an issue where the driver would fail to probe switch trees that contained chips of the Agate/Topaz generation which did not declare STU support, as loaded VTU entries would be read back as invalid.

So ensure that chips that claim STU support can also talk to the hardware.
