  available registers:
  Usage: perf record [<options>] [<command>]

With this change, the registers are listed.

It's also now possible to record subsets of registers on aarch64:

It calculates IPC from the cycles and instruction counts and compares it
with the shadow stat for both global aggregation (default) and no
aggregation mode.

 $ perf stat -a -A -e cycles,instructions sleep 1

   Performance counter stats for 'system wide':

  CPU0   39,580,880      cycles
  CPU1   45,426,945      cycles
  CPU2   31,151,685      cycles
  CPU3   55,167,421      cycles
  CPU0   17,073,564      instructions      #    0.43  insn per cycle
  CPU1   34,955,764      instructions      #    0.77  insn per cycle
  CPU2   15,688,459      instructions      #    0.50  insn per cycle
  CPU3   34,699,217      instructions      #    0.63  insn per cycle

       1.003275495 seconds time elapsed

In this example, the 'insn per cycle' should be matched to the number
for each cpu.  For CPU2, 0.50 = 15,688,459 / 31,151,685 .

Pull locking fixes from Thomas Gleixner:
 "Two more places which invoke tracing from RCU disabled regions in the
  idle path.

  Similar to the entry path the low level idle functions have to be
  non-instrumentable"

Pull irq fixes from Thomas Gleixner:
 "Two fixes for irqchip drivers:

   - Save and restore the GICV3 ITS state unconditionally on
     suspend/resume to handle firmware which fails to do so.

   - Use the correct index into the fwspec parameters to read the irq
     trigger type in the EXIU chip driver"

Pull EFI fixes from Borislav Petkov:
 "More EFI fixes forwarded from Ard Biesheuvel:

   - revert efivarfs kmemleak fix again - it was a false positive

   - make CONFIG_EFI_EARLYCON depend on CONFIG_EFI explicitly so it does
     not pull in other dependencies unnecessarily if CONFIG_EFI is not
     set

   - defer attempts to load SSDT overrides from EFI vars until after the
     efivar layer is up"

   - Two resctrl fixes to prevent refcount leaks when manipulating the
     resctrl fs (Xiaochen Shen)

   - Correct prctl(PR_GET_SPECULATION_CTRL) reporting (Anand K Mistry)

   - A fix to not lose already seen MCE severity which determines
     whether the machine can recover (Gabriele Paoloni)"

Pull RISC-V fixes from Palmer Dabbelt:
 "I've collected a handful of fixes over the past few weeks:

   - A fix to un-break the build-id argument to the vDSO build, which is
     necessary for the LLVM linker.

   - A fix to initialize the jump label subsystem, without which it (and
     all the stuff that uses it) doesn't actually function.

   - A fix to include <asm/barrier.h> from <vdso/processor.h>, without
     which some drivers won't compile"

* tag 'riscv-for-linus-5.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
