From: James Hogan Date: Mon, 9 Dec 2013 17:05:03 +0000 (+0000) Subject: uclibc: add patch to fix arch specific eventfd defs X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d712a018dddbccf6f80e1ecfc3e08385d36bfebc;p=buildroot.git uclibc: add patch to fix arch specific eventfd defs Add uClibc 0.9.33.2 patch to fix arch specific eventfd definitions, particularly EFD_NONBLOCK. The definition in sys/eventfd.h was 04000 (0x800), however MIPS uses 0200 (0x80). This resulted in QEMU built for MIPS hanging at various points until input is received due to a blocking poll of stdin. The patch is a backport of uClibc commit fd355bc1dbcb (eventfd.h: Use new "bits/" scheme for arch-specific flags). The only conflict was minor in Makefile.in.
