    Subject[PATCH v4 0/4] ACPI: hotplug messages improvement
    This patchset improves logging messages for ACPI CPU, Memory, and
    Container hotplug notify handlers. The patchset introduces a set of
    new macro interfaces, acpi_pr_<level>(), and updates the notify
    handlers to use them. acpi_pr_<level>() appends "ACPI" prefix and
    ACPI object path to the messages, and its usage model is similar to
    dev_<level>(). This improves diagnostics in hotplug operations
    since it identifies an object that caused an issue in a log file.

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

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

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

    This patchset applies on top of the patch below.
