0001-Adding-ability-to-detect-non-posix-extensions-for-pt.patch
0002-Allow-for-use-of-either-pthread-affinity-set-methods.patch
removed since they're included in 6.15.

Changelog:
=========
Adjust rngtests for better behavior in travis
fix use of non-posix setaffinity call to allow building on strict posix (musl) systems
Add armv6l to list of detected arches for pkcs11
misc fixes to allow building on libc-musl
fix a deadlock in jitter shutdown sequence
minor warning fixups (unused variables)
improve cpu detection code
improve jitter cpu monopolization on small/single cpu systems

-Subject: [PATCH] Adding ability to detect non-posix extensions for pthreads
-
-Theres a desire to build rngd with musl, which doesn't have all the gnu
-extensions (but it has some).  So test for those.  Note, this requires
-the addition of the USE_EXTENSIONS macro to enable -d_GNU_SOURCE

-Subject: [PATCH] Allow for use of either pthread affinity set methods
-
-musl has support for pthread_setaffinity_np, but not
-pthread_attr_setaffinity_np.  so check for hte existence of either
-function in configure, and use the appropriate one.
