This patch add multithreaded probing with more parallelism control.
The device/driver probing is done on a probing queue, which is a
customized version of work queue, where the thread of probing queue will
come and go on demand
the bus scanning thread
can be created and destroyed on demanded too.
Thank you very much for your comment.

And a workqueue like the probing queue whose thread can be
created/destroyed on demand will save more resources than ordinary
workqueue. :)

for this. The parallel control mechanism can be used to implement
multithreaded device probing in needed subsystems too.

1. A normal kernel is booted.
2. Checking whether there is a effective hibernation image. If there
isn't, continue the normal boot process; otherwise, a resuming
kernel is kexeced in memory 0~16M. The resuming process will
continue in kexeced resuming kernel.

There is much similarity between sys_kexec_load and software resuming.
If resuming can be done by sys_kexec_load, then we need not two similar
functionality in kernel.

The changelog between v1 and v2
1. The kexec jump implementation is put into the kexec/kdump
framework instead of software suspend framework. The device
and CPU state save/restore code of software suspend is called
when needed.
2. The same code path is used for both kexec a new kernel
is called to implement corresponding function.

In fact, I've got no clue what an ICR is.
I dug about a bit, I borrowed that code from:

Huang Ying, can you explain to Jan why you do the wait afterwards
Otherwise, if a large amount of direct IO writes were done, the
segment allocation may be failed because no enough segments are gced.

Yes. I think so too. So you prefer to add f2fs_balance_fs in both
f2fs_direct_IO and get_data_block, or just add f2fs_blance_fs in
get_data_block only?
