KVM: x86: Add proper ReST tables for userspace MSR exits/flags
Add ReST formatting to the set of userspace MSR exits/flags so that the resulting HTML docs generate a table instead of malformed gunk. This also fixes a warning that was introduced by a recent cleanup of the relevant documentation (yay copy+paste). >> Documentation/virt/kvm/api.rst:7287: WARNING: Block quote ends without a blank line; unexpected unindent. Fixes: 1ae099540e8c ("KVM: x86: Allow deflecting unknown MSR accesses to user space") Fixes: 1f158147181b ("KVM: x86: Clean up KVM_CAP_X86_USER_SPACE_MSR documentation") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20221207000959.2035098-1-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
