    Subject[PATCH 0/3] ACPI: Re-factor and remove ./drivers/acpi/atomicio.[ch]
    I recently submitted a patch series that re-factored some existing
    work that Huang Ying introduced adding support for accessing ACPI
    generic registers, backed by Memory Mapped I/O (MMIO), while within
    interrupt context:
    Original series:
    Follow on series:

    An underlying goal has been to re-factor ./drivers/acpi/atomicio.c into
    ./drivers/acpi/osl.c, providing equivalent functionality but in a more
    generalized manner, to allow usage in non-specific (i.e. APEI) contexts
    and remove atomicio.c.

    In the most recent follow on series, there ended up being additions to
    atomicio.c that coincided with the attempt to remove it and as such, the
    series final removal patch could not be taken without first pulling the
    additions into osl.c. The fact that the follow on series conversion
    patch - commit 700130b41f4 - was taken has inadvertently created
    regressions with respect to the recent atomicio.c additions due to the
    conversion patch effectively making atomicio.c obsolete.

    The additions were commit 04c25997c97 "ACPI, Add 64bit read/write
    support to atomicio on i386" and commit 76da3fb3575 "ACPI, Add RAM
    mapping support to ACPI atomic IO support".

    This patch series addresses both of these issues, bringing in the
    additional functionality into the re-factored files (apei-base.c and
    osl.c) and then again, reintroduces the patch to remove

    ACPI: Remove ./drivers/acpi/atomicio.[ch]
    ACPI, APEI: Add RAM mapping support to ACPI
    ACPI, APEI: Add 64-bit read/write support for APEI on i386
