Merge tag 'riscv-for-linus-4.21-rc2-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux

Pull RISC-V updates from Palmer Dabbelt:
 "This tag contains a handful of updates that slipped through the cracks
  during the merge window due to the holidays. The fixes are mostly
  independent, with the exception of one larger audit-related branch.

  Core RISC-V updates:

   - The BSS has been moved, which shrinks flat images.

   - A fix to test-bpf so it compiles on RV64I-based systems.

   - A fix to respect the kernel commandline when there is no device
     tree.

   - A fix to prevent CPUs from trying to put themselves to sleep when
     bringing down the system.

   - Support for MODULE_SECTIONS on RV32I-based systems.

   - [new in v2] The addition of an SBI earlycon driver. This is
     definately a new feature, but I'd like to include it now because I
     dropped this patch when submitting the merge window PR that removed
     our EARLY_PRINTK support.

  RISC-V audit updates:

   - The addition of NR_syscalls into unistd.h, which is necessary for
     CONFIG_FTRACE_SYSCALLS.

   - The definition of CREATE_TRACE_POINTS so __tracepoint_sys_{enter,exit}
     get defined.

   - A fix for trace_sys_exit() so we can enable HAVE_SYSCALL_TRACEPOINTS

  As usual, I've tested this by booting a Fedora-based image on a recent
  QEMU (this time just whatever I had lying around).
