[PATCH v5 RESEND 0/5] ACPI: hotplug messages improvement

[Toshi Kani <toshi.kani@hp.com>]

This patchset improves logging messages for ACPI CPU, Memory, 
Container and Dock hotplug notify handlers.  The patchset 
introduces a set of new macro interfaces, acpi_pr_<level>(),
and uses them to update the notify handlers.  acpi_pr_<level>()
appends "ACPI" prefix and ACPI object path to the messages,
which has similar usage model as dev_<level>().  This improves
diagnosis of hotplug operations since an error message in 
a log file now identifies an object that caused an issue.

The patchset is based on the linux-next branch of linux-pm.git
tree.

v5:
 - Added update for ACPI Dock hotplug error messages.
 - Added error status / ID info to the messages where needed.

v4:
 - Changed to use dev_<level>() where it is appropriate.

v3:
 - Changed acpi_pr_debug() to NOP when !DEBUG and !DYNAMIC_DEBUG.
   DYNAMIC_DEBUG will be supported later when necessary.
 - Added const to a path variable in acpi_printk().
 - Added more descriptions to the change log of patch 1/4.

v2:
 - Set buffer.pointer to NULL in acpi_printk().
 - Added acpi_pr_debug().
