entries to that section. Move hrtimers immediately after
this new section so that they are all together.

Add the generated atomic headers to driver-api/basics.rst in order to
provide documentation for the Linux kernel's atomic operations.
At the same time, dtop the x86 atomic header, which provides kerneldoc
comments for some arch_atomic*_*() operations. The arch_atomic*_*()
operations are now purely an implenentation detail of the
raw_atomic*_*() ops, and outside of implementing the atomics, code
should use the raw_atomic*_*() forms.
[Mark: add atomic-{instrumented,long}.h, update commit message]

Fix the kern-doc markings for several of the overflow helpers and move
their location into the core kernel API documentation, where it belongs
(it's not driver-specific).

pci_device_id is already documented at pci.rst:
./Documentation/driver-api/basics.rst: WARNING: Duplicate C declaration, also defined in 'PCI/pci'.
Declaration is 'pci_device_id'.
The kstrtol and kstrtoul are already at kernel-api:
./Documentation/driver-api/basics.rst: WARNING: Duplicate C declaration, also defined in 'core-api/kernel-api'.
Declaration is 'kstrtoul'.
./Documentation/driver-api/basics.rst: WARNING: Duplicate C declaration, also defined in 'core-api/kernel-api'.

And the printk is already defined at printk-basics:

Declaration is 'printk'.
So, exclude those identifiers from basirs.rst.

As discussed in the "API replacement/deprecation" thread[1], this makes
an effort to document what things shouldn't get (re)added to the kernel,
by introducing Documentation/process/deprecated.rst.

Some functions from refcount_t API provide different
memory ordering guarantees that their atomic counterparts.
This adds a document outlining these differences (
Documentation/core-api/refcount-vs-atomic.rst) as well as
some other minor improvements.

The docs build complains:
./include/linux/init.h:1: warning: no structured comments found
The problem is that the comments in question were moved to module.h in
commit 0fd972a7d9 (module: relocate module_init from init.h to
module.h). Fix basics.rst to match.
