[ Upstream commit 6f051e4a685b768f3704c7c069aa1edee3010622 ]
[resend due to me forgetting to cc: linux-api the first time around I posted these back on Feb 23]
From: Greg Kroah-Hartman gregkh@linuxfoundation.org
When userspace tries to use these defines, it complains that it needs to be an unsigned 1 that is shifted, so libc implementations have to create their own version. Fix this by defining it properly so that libcs can just use the kernel uapi header.
