[$] Who are kernel defconfigs for?

Working on the kernel can be a challenging task but, for many,configuring a kernel build can be the largest obstacle to gettingstarted. The kernel has thousands of configuration options; many of those,if set incorrectly, will result in a kernel that does not work on thetarget system. The key to helping users with complex configurationproblems is to provide reasonable defaults but, in the kernel community,there is currently little consensus around what those defaults should be.
