From 4336efe14b61e47177a2d0863f8391c48cf4a9f5 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 3 Jun 2017 12:59:55 +0200 Subject: kernel: use upstream patches for musl This replaces the current patches used to make the kernel headers compatible with musl with the version which was accepted upstream. This is included in upstream kernel 4.15. This was compile tested with iproute2 build on all supported kernel versions with musl and one one with glibc.
