Pull perf tooling updates from Ingo Molnar: "Tooling changes only: fixes and a few stray improvements.

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).

We use syscall.tbl to generate system call table on powerpc. The unistd.h copy is no longer required now. Remove it.

Commit aff850393200 ("powerpc: add system call table generation
support") changed how systemcall table is generated for powerpc.
Incorporate these changes into perf as well.
