Revision	Date	Author	Comments
1.4	10-May-2020	maxv	Reintroduce cpu_rng_early_sample(), but this time with embedded detection for RDRAND/RDSEED, because TSC is not very strong.
1.3	30-Apr-2020	riastradh	Simplify Intel RDRAND/RDSEED and VIA C3 RNG API. Push it all into MD x86 code to keep it simpler, until we have other examples on other CPUs. Simplify RDSEED-to-RDRAND fallback. Eliminate cpu_earlyrng in favour of just using entropy_extract, which is available early now.
1.2	21-Jul-2018	maxv	More ASLR. Randomize the location of the direct map at boot time on amd64. This doesn't need "options KASLR" and works on GENERIC. Will soon be enabled by default. The location of the areas is abstracted in a slotspace structure. Ideally we should always use this structure when touching the L4 slots, instead of the current cocktail of global variables and constants. machdep initializes the structure with the default values, and we then randomize its dmap entry. Ideally machdep should randomize everything at once, but in the case of the direct map its size is determined a little later in the boot procedure, so we're forced to randomize its location later too.
