[BUG][PATCH] process events connector - uid_t gid_t size issues

[Matt Helsley <matthltc@us.ibm.com>]

Andrew,

	I noticed this follow up patch did not make it's way into -mm and
subsequently to 2.6.15-rc2. The uid_t and gid_t fields appear to present
a 32/64-bit userspace/kernel problem for some archs.

	This patch addresses the problem by fixing the size to the largest
size for uid_t/gid_t used in the kernel. This preserves the total size of
the event structure while ensuring that the layouts of the ID change event
match in 32 and 64-bit kernels and applications.

	Please apply.
