Doc Text Cause:

The RT patchset causes the kernel function smp_processor_id() to be called in atomic context from the function __cycles_2_ns().

Consequence:

Console warnings that a sleeping lock is being acquired in atomic context.

Fix:

Apply upstream commit 5dd12c21 which changes the way the __cyles_2_ns() does a 64-bit multiplication, thus removing the need for a call to smp_processor_id().

Result:

Operations with no console warnings due to calls to __cycles_2_ns() inside atomic context.
