In order to support cxlflash in the PowerVM environment, underlying hypervisor APIs have imposed a kernel API ordering change. For the superpipe access to LUN, user applications need a context. The cxlflash module creates this context by making a sequence of cxl calls. In the current code, a context is initialized via cxl_dev_context_init() followed by cxl_process_element(), a function that obtains the process element id. Finally, cxl_start_work() is called to attach the process element. In the PowerVM environment, a process element id cannot be obtained from the hypervisor until the process element is attached. The cxlflash module is unable to create contexts without a valid process element id. To fix this problem, cxl_start_work() is called before obtaining the process element id.
