I have tested the whole series on my Creator CI20 with success, using:

Add a note that it is perfectly legal to "abandon" a request object:
- call .init() and then (as many times) .update()
- _not_ call any of .final(), .finup() or .export() at any point in
future

Recently, we hoped to make the possible CPU count more accurate for
Kernel. I stuck on the issue how do I run acpi_early_init() _before_
setup_percpu() is invoked. So send these insignificant patches first.
This patchset does this things:
- two document-related work(the 1th and 2th patch),
-
In prefill_possible_map(), Kernel need to get the number of possible CPUs
to reset cpu_possible_map. The number is related to the options:
-nosmp, maxcpus, possible_cpus, nr_cpus
... which need to be checked.
Currentlly, the check code mixed these options together in confusion and
hard to foll
The acpi_duplicate_processor_id() is only called in acpi_processor_get_info(),
So move it in front of acpi_processor_get_info() and make it static.
