Previously, this command returns no help message on aarch64:
-> ./perf record --user-regs=?
available registers:
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
With this change, the registers are listed.
-> ./perf record --user-regs=?
available registers: x0 x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11 x12 x13 x14 x15 x16 x17 x18 x19 x20 x21 x22 x23 x24 x25 x26 x27 x28 x29 lr sp pc
It's also now possible to record subsets of registers on aarch64:
-> ./perf record --user-regs=x4,x5 ls
-> ./perf report --dump-raw-trace

Checked that the registers can be listed with =? and that recording different combinations of registers works as expected.

Except this patch for enabling registers on aarch64, it's good to add
arm32's version in the file arch/arm/util/perf_regs.c.
Just note for a side topic, I checked a bit for the implementation for
x86/powerpc, you could consider to enable Statically Defined Tracing
in the perf_regs.c file as well. This can be separate task for
arm/arm64.
Thanks,
