"Another handful of arm64 fixes here. Most of the complication comes
from improving our kpti code to avoid lengthy pauses (30+ seconds)

it exists in the current dtb.
So "ret" should be reset to 0 here.

When executed for a PCI_ROOT_COMPLEX type, iort_match_node_callback()
expects the opaque pointer argument to be a PCI bus device. At the
moment rc_dma_get_range() passes the PCI endpoint instead of the bus,
and we've been lucky to have pci_domain_nr(ptr) return 0 instead of
crashing. Pass the bus device to iort_scan_node().

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.
There's more information about the audit branch in that merge, the rest
are:
* 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.
As usual, I've tested this by booting a Fedora-based image on a recent
QEMU (this time just whatever I had lying around).

A side effect of commit c55191e96c ("arm64: mm: apply r/o permissions
of VM areas to its linear alias as well") is that the linear map is
created with page granularity, which means that transitioning the early
page table from global to non-global mappings when enabling kpti can
take a significant amount of time during boot.
Given that most CPU implementations do not require kpti, this mainly
impacts KASLR builds where kpti is forcefully enabled. However, in these
situations we know early on that non-global mappings are required and
can avoid the use of global mappings from the beginning. The only gotcha
is Cavium erratum #27456, which we must detect based on the MIDR value
of the boot CPU.

The conversion to use a structure for mmu_notifier_invalidate_range_*()
unintentionally changed the usage in try_to_unmap_one() to init the

i.e. it invalidates the wrong address range. Revert to the correct

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.
