Re: [PATCH] kselftests: update to 4.10

[Denys Dmytriyenko <denys@ti.com>]

Thanks! I mostly like it, but have couple comments - see below.

Does it mean that targets for specific architectures won't be skipped, but 
rather fail? I.e. ipc for x86 when building for arm?

Not sure about headers_install - can headers from linux-libc-headers be used 
instead?

I see it also uses BINARIES instead of TEST_PROGS, like sigaltstack. Try 
changing that - should fix the install part, as top-level Makefile uses 
TEST_PROGS as a list of binaries to install.

Thanks! I was considering doing this before...
