  system call names in the arch/powerpc/kernel/syscalls/syscall.tbl

   - Fix build failures with both CONFIG_NLS and CONFIG_PCI unset that
     can occur since ACPI can be built without PCI now (Sinan Kaya).

   - Clean up the handling of duplicate entries in power resource lists
     returned by _PRx evaluation to avoid triggering WARN_ON() on
     attempts to add duplicate symlinks in sysfs (Hans de Goede).

   - Fix issues with the TS current-source switching on systems using
     the xpower PMIC by avoiding to update unrelated bits in the TS
     pin-ctrl register and avoiding to unconditionally enable TS
     current-source on systems where it is not used (Hans de Goede).

   - Prevent the cpufreq core from attempting to return the current
     frequency of offline CPUs (Sudeep Holla).

   - Add devfreq suspend and resume hooks (missed previously) to the PM
     core to make the recently added system suspend and resume support

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).

The conversion to use a structure for mmu_notifier_invalidate_range_*()
unintentionally changed the usage in try_to_unmap_one() to init the
'struct mmu_notifier_range' with vma->vm_start instead of @address,
i.e. it invalidates the wrong address range.  Revert to the correct
address range.

Manifests as KVM use-after-free WARNINGs and subsequent "BUG: Bad page
state in process X" errors when reclaiming from a KVM guest due to KVM
removing the wrong pages from its own mappings.

When testing 'perf top' on a armhf system (32-bit, Orange Pi Zero), I
noticed that 'arch_cpu_idle' dominated, add it to the list of idle
symbols, so that we can see what is that being done when not idle.

The scmi-cpufreq driver calls the arch_set_freq_scale() callback on
frequency changes to provide scale-invariant load-tracking signals to
the scheduler. However, in the slow path, it does so while specifying
the current and max frequencies in different units, hence resulting in a
broken freq_scale factor.

Fix this by passing all frequencies in KHz, as stored in the CPUFreq
frequency table.

Initially DP0_SRCCTRL is set to a static value which includes
DP0_SRCCTRL_LANES_2 and DP0_SRCCTRL_BW27, even when only 1 lane of
1.62Gbps speed is used. DP1_SRCCTRL is configured to a magic number.

This patch changes the configuration as follows:

Configure DP0_SRCCTRL by using tc_srcctrl() which provides the correct
value.

DP1_SRCCTRL needs two bits to be set to the same value as DP0_SRCCTRL:
SSCG and BW27. All other bits can be zero.

CONFIG_RESCTRL is too generic. The final goal is to have a generic
option called like this which is selected by the arch-specific ones
CONFIG_X86_RESCTRL and CONFIG_ARM64_RESCTRL. The generic one will
cover the resctrl filesystem and other generic and shared bits of
functionality.
