I saw

MEMORY MANAGEMENT
M:      Andrew Morton <akpm@linux-foundation.org>
L:      linux-mm@kvack.org
S:      Maintained

in the MAINTAINERS file, so I sent the patch to Andrew and to 
linux-mm@kvack.org. I should have sent it also to people on the "MEMORY 
MANAGEMENT - CORE" section, but I missed it.

I'm developing code that translates parallelizable loops written in the 
Ajla programming language (www.ajla-lang.cz) into OpenCL and runs them on 
the graphics card. Ajla sets up a periodic timer that sends a signal for 
scheduling purposes and this signal interferes with OpenCL, causing the 
-EINTR failures.

So far, I worked around this bug by blocking all signals around the 
functions clGetPlatformIDs and clGetDeviceIDs - but it would be better to 
fix it in the Linux kernel and remove the signal-blocking hacks.
