toolchain/uClibc/patches-0.9.33.2/999-eventfd_use_bits_scheme.patch

   1 From fd355bc1dbcb794ae1abf0fad1459e28d8567ba0 Mon Sep 17 00:00:00 2001
   2 From: Hiroaki KAWAI <kawai@stratosphere.co.jp>
   3 Date: Fri, 19 Apr 2013 01:09:35 +0000
   4 Subject: eventfd.h: Use new "bits/" scheme for arch-specific flags
   5
   6 As in timerfd.h, eventfd.h needs arch-specific definition files.
   7 alpha, mips and sparc needs separate file, all the other arch
   8 will use common definition.
   9
  10 This problem is already fixed in glibc.
  11
  12 Also sanitize and provide bits for hppa.
  13 Make sure not to install the new bits/eventfd unless eventfd support is
  14 enabled.
