Subject: [PATCH 11/30] aio: Use __kernel_ulong_t to define aio_context_t

From: "H. Peter Anvin" <hpa@...or.com>

Rather than using "unsigned long" which is ABI-dependent, use
__kernel_ulong_t to define the externally visible type aio_context_t.

Note: the change in this form will cause unsigned long/unsigned int
differences on existing ABIs.  If that is unacceptable we may have to
define a new type.
