Linus Torvalds 4f548c25a3 RISC-V Updates for 4.21-rc2 v2

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.
There's more information about the audit branch in that merge, the rest
are:

* 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.

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

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).
