It seems that the CPUs part of the SoC known as Apple M1 have the
terrible habit of being stuck with HCR_EL2.E2H==1, in violation
of the architecture.
Try and work around this deplorable state of affairs by detecting
the stuck bit early and short-circuit the nVHE dance. Additional
filtering code ensures that attempts at switching to nVHE from
the command-line are also ignored.
It is still unknown whether there are many more such nuggets
to be found...

Some CPUs are broken enough that some overrides need to be rejected
at the earliest opportunity. In some cases, that's right at cpu
feature override time.
Provide the necessary infrastructure to filter out overrides,
and to report such filtered out overrides to the core cpufeature code.

Currently we require that software at a higher exception level initialise
all registers at the exception level the kernel will be entered prior to
starting the kernel in order to ensure that there is nothing uninitialised
which could result in an UNKNOWN state while running the kernel. The
expectation is that the software running at the highest exception levels
will be tightly coupled to the system and can ensure that all available
features are appropriately initialised and that the kernel can initialise
anything else.
There is a gap here in the case where new registers are added to lower
exception levels that require initialisation but the kernel does not yet
understand them. Extend the requirement to also include exception levels
below the one where the kernel is entered to cover this.

Pull devfreq updates for v5.13 from Chanwoo Choi:
"1. Update devfreq core
- Register devfreq as a cooling device when adding devfreq device,
basically if the flag of devfreq device is set as cooling device.
- Add missing unlock opeation in devfreq_add_device
- Use the next frequency as resume_freq instead of previous frequency
when using opp-suspend property
- Check whether .get_dev_status in struct devfreq_dev_profile is
implemented or not by devfreq driver before calling .get_dev_status
function.
2. Update devfreq drivers
- Use dev_err_probe to simplify the error handling on rk3399_dmc.c
- Remove unused .get_dev_status function on imx8m-ddrc.c because
imx8m_ddrc_get_dev_status has not returend the any current status
of the device.
- Remove unneeded of_match_ptr() from imx-bus.c and imx8m-ddrc.ca
- Add missing phandle informatioon and replace undefined variable
with integer value for rk3399_dmc.txt devicetree binding document.
3. Fix minor issues
- Fix the wrong set_freq path of userspace governor in
drivers/devfreq/Kconfig.
- Remove the invalid description from .get_target_freq in struct
devfreq_dev_profile."

In ice_suspend(), ice_clear_interrupt_scheme() is called, and then
irq_free_descs() will be eventually called to free irq and its descriptor.
In ice_resume(), ice_init_interrupt_scheme() is called to allocate new
irqs. However, in ice_rebuild_arfs(), struct irq_glue and struct cpu_rmap
maybe cannot be freed, if the irqs that released in ice_suspend() were
reassigned to other devices, which makes irq descriptor's affinity_notify
lost.
So call ice_free_cpu_rx_rmap() before ice_clear_interrupt_scheme(), which
can make sure all irq_glue and cpu_rmap can be correctly released before
corresponding irq and descriptor are released.
Fix the following memory leak.

When we enable SVE usage in userspace after taking a SVE access trap we
need to ensure that the portions of the register state that are not
shared with the FPSIMD registers are zeroed. Currently we do this by
forcing the FPSIMD registers to be saved to the task struct and converting
them there. This is wasteful in the common case where the task state is
loaded into the registers and we will immediately return to userspace
since we can initialise the SVE state directly in registers instead of
accessing multiple copies of the register state in memory.
Instead in that common case do the conversion in the registers and
update the task metadata so that we can return to userspace without
spilling the register state to memory unless there is some other reason
to do so.

Fixes for omaps for v5.12-rc cycle
Fix swapped mmc device order also for omap3 that got changed with the
recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the aliases
should be board specific, all the mmc device instances are all there in
the SoC, and we do probe them by default so that PM runtime can idle the
devices if left enabled from the bootloader.
Also included are two compiler warning fixes.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull close_range() fix from Christian Brauner:
"Syzbot reported a bug in close_range.
Debugging this showed we didn't recalculate the current maximum fd
number for CLOSE_RANGE_UNSHARE | CLOSE_RANGE_CLOEXEC after we unshared
the file descriptors table. As a result, max_fd could exceed the
current fdtable maximum causing us to set excessive bits.
As a concrete example, let's say the user requested everything from fd
4 to ~0UL to be closed and their current fdtable size is 256 with
their highest open fd being 4. With CLOSE_RANGE_UNSHARE the caller
will end up with a new fdtable which has room for 64 file descriptors
since that is the lowest fdtable size we accept. But now max_fd will
still point to 255 and needs to be adjusted. Fix this by retrieving
the correct maximum fd value in __range_cloexec().
I've carried this fix for a little while but since there was no
linux-next release over easter I waited until now.
With this change close_range() can be further simplified but imho we
are in no hurry to do that and so I'll defer this for the 5.13 merge
window"

ARM SCMI updates for v5.13
The major and big addition this time is to support modularisation of
individual SCMI protocols thus enabling to add support for vendors'
custom SCMI protocol. This changes the interface provided by the SCMI
driver to all the users of SCMI and hence involved changes in various
other subsystem SCMI drivers. The change has been split with a bit of
transient code to preserve bisectability and avoiding one big patch bomb
changing all the users.
This also includes SCMI IIO driver(pulled from IIO tree) and support for
per-cpu DVFS.

Given that no validation of how much data the firmware loader read in
for a given segment truncated segment files would best case result in a
hash verification failure, without any indication of what went wrong.

Pull umount fix from Al Viro:
"Brown paperbag time: dumb braino in the series that went into 5.7
broke the 'don't step into ->d_weak_revalidate() when umount(2) looks
the victim up' behaviour.
Spotted only now - saw
if (!err && unlikely(nd->flags & LOOKUP_MOUNTPOINT)) {
err = handle_lookup_down(nd);
nd->flags &= ~LOOKUP_JUMPED; // no d_weak_revalidate(), please...
}
and went "why do we clear that flag here - nothing below that point is
going to check it anyway" / "wait a minute, what is it doing *after*
complete_walk() (which is where we check that flag and call
->d_weak_revalidate())" / "how could that possibly _not_ break?",
followed by reproducing the breakage and verifying that the obvious
fix of that braino does, indeed, fix it.
The reproducer is (assuming that $DIR exists and is exported r/w to
localhost)
mkdir $DIR/a
mkdir /tmp/foo
mount --bind /tmp/foo /tmp/foo
mkdir /tmp/foo/a
mkdir /tmp/foo/b
mount -t nfs4 localhost:$DIR/a /tmp/foo/a
mount -t nfs4 localhost:$DIR /tmp/foo/b
rmdir /tmp/foo/b/a
umount /tmp/foo/b
umount /tmp/foo/a
umount -l /tmp/foo # will get everything under /tmp/foo, no matter what
Correct behaviour is successful umount; broken kernels (5.7-rc1 and
later) get
umount.nfs4: /tmp/foo/a: Stale file handle
Note that bind mount is there to be able to recover - on broken
kernels we'd get stuck with impossible-to-umount filesystem if not for
that.
FWIW, that braino had been posted for review back then, at least
twice. Unfortunately, the call of complete_walk() was outside of diff
context, so the bogosity hadn't been immediately obvious from the
patch alone ;-/"

The commit in Fixes: changed the SGX EPC page sanitization to end up in
sgx_free_epc_page() which puts clean and sanitized pages on the free
list.
This was done for the reason that it is best to keep the logic to assign
available-for-use EPC pages to the correct NUMA lists in a single
location.
sgx_nr_free_pages is also incremented by sgx_free_epc_pages() but those
pages which are being added there per EPC section do not belong to the
free list yet because they haven't been sanitized yet - they land on the
dirty list first and the sanitization happens later when ksgxd starts
massaging them.
So remove that addition there and have sgx_free_epc_page() do that
solely.
[ bp: Sanitize commit message too. ]
