Subject: [PATCH] Support kernel/hotplug sysctl variable when !CONFIG_NET

From: Ian Abbott <abbotti@....co.uk>

The kernel/hotplug sysctl variable (/proc/sys/kernel/hotplug file) was
made conditional on CONFIG_NET by commit
f743ca5e10f4145e0b3e6d11b9b46171e16af7ce (applied in 2.6.18) to fix
problems with undefined references in 2.6.16 when CONFIG_HOTPLUG=y &&
!CONFIG_NET, but this restriction is no longer needed.

This patch makes the kernel/hotplug sysctl variable depend only on
CONFIG_HOTPLUG.
