Changes in v2:
Change log typo was not correct.
Changes in v3:
To support the LRNG operation which allocates the Jitter RNG separately
from the kernel crypto API, extract the relevant information into a
separate header file.

Hi,
after distributing patches for the Linux-RNG - a new approach for the last
half year, I would like to submit this RFC for inclusion into the kernel.
The following patch set provides a different approach to /dev/random which
I call Linux Random Number Generator (LRNG) to collect entropy within
When selecting the LRNG for compilation, disable add_disk_randomness and
its supporting function.

It is no need to find the very beginning of the area within

For current approach, the worst case is that the starting node which be found
for searching the 'vmap_area_list' is close to the 'vstart', while the final
