This patch provides fixes for the following issues: 1. Fix issue of controller reset required to send commands. For reset process, it may be required to send commands to the controller, but not during soft reset. So add HISI_SAS_NOT_ACCEPT_CMD_BIT to prevent executing a task during this period. 2. Send a broadcast event in rescan topology to detect any topology changes during reset. 3. Previously it was not ensured that libsas has processed the PHY up and down events after reset. Potentially this could cause an issue that we still process the PHY event after reset. So resolve this by flushing shot workqueue in LLDD reset. 4. Port ID requires refresh after reset. The port ID generated after reset is not guaranteed to be the same as before reset, so it needs to be refreshed for each device's ITCT.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
