Enable ring-based dirty memory tracking on riscv: - Enable CONFIG_HAVE_KVM_DIRTY_RING_ACQ_REL as riscv is weakly ordered. - Set KVM_DIRTY_LOG_PAGE_OFFSET for the ring buffer's physical page offset. - Add a check to kvm_vcpu_kvm_riscv_check_vcpu_requests for checking whether the dirty ring is soft full. To handle vCPU requests that cause exits to userspace, modified the `kvm_riscv_check_vcpu_requests` to return a value (currently only returns 0 or 1).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
