    Subject[GIT PULL] cxl fixes for v5.12-rc8 / final
    Hi Linus, please pull from:

    git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
    tags/cxl-fixes-for-5.12-rc8

    ...to receive a collection of fixes for the CXL memory class driver
    introduced in v5.12-rc1.

    The driver was primarily developed on a work-in-progress QEMU
    emulation of the interface and we have since found a couple places
    where it hid spec compat bugs in the driver, or had a spec
    implementation bug itself. The biggest change here is replacing a
    percpu_ref with an rwsem to cleanup a couple bugs in the error unwind
    path during ioctl device init. Lastly there were some minor cleanups
    to not export the power-management sysfs-ABI for the ioctl device, use
    the proper sysfs helper for emitting values, and prevent subtle bugs
    as new administration commands are added to the supported list.

    The bulk of it has appeared in -next save for the top commit which was
    found today and validated on a fixed-up QEMU model.

    cxl/mem: Fix memory device capacity probing (2021-04-16 18:21:56 -0700)

    ----------------------------------------------------------------
    cxl for 5.12-rc8

    - Fix support for CXL memory devices with registers offset from the BAR

    - Fix the reporting of device capacity.

    - Fix the driver commands list definition to be disconnected from the
    UAPI command list.

    - Replace percpu_ref with rwsem to fix initialization error path.

    - Fix leaks in the driver initialization error path.

    - Drop the power/ directory from CXL device sysfs.

    - Use the recommended sysfs helper for attribute 'show' implementations.
