very nice patch! I always thought that this was the proper way to do
memtest - and we could in fact also do something like this after SMP
bringup, and hit the memory bus via multiple CPUs. [that will need a
different enumeration though than e820 maps]
one structural observation: please make this unified functionality, so
that 32-bit kernels can make use of it too.
Indeed. Of course, it would also be nice if distros shipped
bootloader-invoked prekernel test software, like memtest86+, by default.
