Create two files in /sys/kernel, kexec_loaded and kexec_crash_loaded. Each
file contains a simple boolean value indicating whether the relevant kernel
has been loaded into memory. The motivation for this is geared around
support.Signed-off-by: Jeff Moyer

uevent_seqnum and uevent_helper are only defined if CONFIG_HOTPLUG=y,
CONFIG_NET=n.(I stole this back from Greg's tree - it makes allnoconfig work).

Moving uevent_seqnum and uevent_helper to kobject_uevent.c
because they are used even if CONFIG_SYSFS=n
while kernel/ksysfs.c is built only if CONFIG_SYSFS=y,Signed-off-by: Jun'ichi Nomura

- Kexec on panic functionality allocates memory for saving cpu registers in
case of system crash event. Address of this allocated memory needs to be
exported to user space, which is used by kexec-tools.- Previously, a single /sys/kernel/crash_notes entry was being exported as
memory allocated was a single continuous array. Now memory allocation being
dyanmic and per cpu based, address of per cpu buffer is exported through
"/sys/devices/system/cpu/cpuX/crash_notes"Signed-off-by: Vivek Goyal

kobject_uevent.o is compiled even if !CONFIG_HOTPLUG, which is lazy.
Let's compound the sin.

Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.Signed-off-by: Kay Sievers

This deprecates the /proc/sys/kernel/hotplug file, as all
this stuff should be in /sys some day, right? :)
In /sys/kernel/ we have now uevent_seqnum and uevent_helper.
The seqnum is no longer used by udev, as the version for this
kernel depends on netlink which events will never get
out-of-order.Recent udev versions disable the /sbin/hotplug helper with
an init script, cause it leads to OOM on big boxes by running
hundreds of shells in parallel. It should be done now by:
echo "" > /sys/kernel/uevent_helper(Note that "-n" does not work, cause neighter proc nor sysfs
support truncate().)Signed-off-by: Kay Sievers

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
