----------------------------------------------------------------
RISC-V Patches for the 6.2 Merge Window, Part 1

* Support for the T-Head PMU via the perf subsystem.
* ftrace support for rv32.
* Support for non-volatile memory devices.
* Various fixes and cleanups.

----------------------------------------------------------------
I didn't have a part 2 planned, but I just stumbled into a build issue with
the Arm LPAE IOMMU being enabled on rv32, which is worked around via
https://lore.kernel.org/r/20221214180409.7354-1-palmer@rivosinc.com/ .
Anything would be a fix, though, as I'm essentially pretending we're in RCs
aside from what's here.

I've sent the diffstat against v6.1-rc1, as targeting a recent master produces
something huge (though still a reasonable shortlog).  I'm not entirely sure
what's going on there: I have some old merge bases (due to old patch sets) so
hopefully that's the problem, but it's also my first time seriously using b4 so
sorry if I've screwed something up.  The only intentionally suspect thing I've
done is include 5c20a3a9df19 ("RISC-V: Fix compilation without
RISCV_ISA_ZICBOM") as it fixes a build issue in the following patch set and
didn't land via the usual flow, but I think that's the cleanest way to do it as
the patch was already directly on top of rc1.

I'm seeing one merge conflict, here's my resolution if it helps any:
