commit869c706092upstream. Use what is currently the SMP=y version of riscv_cpuid_to_hartid_mask() for both SMP=y and SMP=n to fix a build failure with KVM=m and SMP=n due to boot_cpu_hartid not being exported. This also fixes a second bug where the SMP=n version assumes the sole CPU in the system is in the incoming mask, which may not hold true in kvm_riscv_vcpu_sbi_ecall() if the KVM guest VM has multiple vCPUs (on a SMP=n system).

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 Restructured Text 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.
