Subject: [PATCH] Export PowerPC atomic operations to userspace
Date: Mon, 15 May 2006 11:54:52 -0500 [thread overview]
Message-ID: <200605151154.52599.bcook@bpointsys.com> (raw)
The atomic operations in asm/atomic.h are really useful from userspace too.
Other architectures (i386, x86_64, mips) export these to userspace, but the
powerpc versions are guarded by __KERNEL__ for some reason. Can we remove
these if there is no good reason to guard them?
