Pull modules fixes from Jessica Yu:
- Revert __ksymtab_$namespace.$symbol naming scheme back to
__ksymtab_$symbol, as it was causing issues with depmod.
Instead, have modpost extract a symbol's namespace from __kstrtabns
and __ksymtab_strings.
- Fix `make nsdeps` for out of tree kernel builds (make O=...) caused
by unescaped '/'.
Use a different sed delimiter to avoid this problem.
* tag 'modules-for-v5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux:
scripts/nsdeps: use alternative sed delimiter
symbol namespaces: revert to previous __ksymtab name scheme

We currently assume that submissions from the sqthread are successful,
and if IO polling is enabled, we use that value for knowing how many
completions to look for. But if we overflowed the CQ ring or some
requests simply got errored and already completed, they won't be
available for polling.
For the case of IO polling and SQTHREAD usage, look at the pending
poll list. If it ever hits empty then we know that we don't have
anymore pollable requests inflight. For that case, simply reset
the inflight count to zero.

We currently use the ring values directly, but that can lead to issues
if the application is malicious and changes these values on our behalf.
Created in-kernel cached versions of them, and just overwrite the user
side when we update them. This is similar to how we treat the sq/cq
ring tail/head updates.

io_sq_thread() processes sqes by 8 without considering links. As a
result, links will be randomely subdivided.
The easiest way to fix it is to call io_get_sqring() inside
io_submit_sqes() as do io_ring_submit().
Downsides:
1. This removes optimisation of not grabbing mm_struct for fixed files
2. It submitting all sqes in one go, without finer-grained sheduling
with cq processing.

Recent cleanup in the way EEH support is added to a device causes a
kernel oops when the cxl driver probes a device and creates virtual
devices discovered on the FPGA:
BUG: Kernel NULL pointer dereference at 0x000000a0
Faulting instruction address: 0xc000000000048070
Oops: Kernel access of bad area, sig: 7 [#1]
...
NIP eeh_add_device_late.part.9+0x50/0x1e0
LR eeh_add_device_late.part.9+0x3c/0x1e0
Call Trace:

cxl_probe+0x504/0x5b0 [cxl]
local_pci_probe+0x6c/0x110
work_for_cpu_fn+0x38/0x60
The root cause is that those cxl virtual devices don't have a
representation in the device tree and therefore no associated pci_dn
structure. In eeh_add_device_late(), pdn is NULL, so edev is NULL and
we oops.
We never had explicit support for EEH for those virtual devices.
Instead, EEH events are reported to the (real) pci device and handled
by the cxl driver. Which can then forward to the virtual devices and
handle dependencies. The fact that we try adding EEH support for the
virtual devices is new and a side-effect of the recent cleanup.
This patch fixes it by skipping adding EEH support on powernv for
devices which don't have a pci_dn structure.
The cxl driver doesn't create virtual devices on pseries so this patch
doesn't fix it there intentionally.

Modify plic_init() to skip .dts interrupt contexts other
than supervisor external interrupt.
The .dts entry for plic may specify multiple interrupt contexts.
For example, it may assign two entries IRQ_M_EXT and IRQ_S_EXT,
in that order, to the same interrupt controller. This patch
modifies plic_init() to skip the IRQ_M_EXT context since
IRQ_S_EXT is currently the only supported context.
If IRQ_M_EXT is not skipped, plic_init() will report "handler
already present for context" when it comes across the IRQ_S_EXT
context in the next iteration of its loop.
Without this patch, .dts would have to be edited to replace the
value of IRQ_M_EXT with -1 for it to be skipped.

The _PPC change notifications from the platform firmware are per-CPU,
so acpi_processor_ppc_init() needs to add a frequency QoS request
for each CPU covered by a cpufreq policy to take all of them into
account.
Even though ACPI thermal control of CPUs sets frequency limits
per processor package, it also needs a frequency QoS request for each
CPU in a cpufreq policy in case some of them are taken offline and
the frequency limit needs to be set through the remaining online
ones (this is slightly excessive, because all CPUs covered by one
cpufreq policy will set the same frequency limit through their QoS
requests, but it is not incorrect).
Modify the code in accordance with the above observations.

During dump flow, the driver allocates spaces to store the memory
regions that will be included in the dump. These regions can be very
large so in order to avoid allocation failure, use vzalloc instead.

fact that the memory is contiguous so the same functionality is
