Use this field to keep the number of supported PASIDs that an IOMMU
hardware is able to support. This is a generic attribute of an IOMMU
and lifting it into the per-IOMMU device structure makes it possible
to allocate a PASID for device without calls into the IOMMU drivers.
Any iommu driver that supports PASID related features should set this
field before enabling them on the devices.
In the Intel IOMMU driver, intel_iommu_sm is moved to CONFIG_INTEL_IOMMU
enclave so that the pasid_supported() helper could be used in dmar.c
without compilation errors.

'struct fscrypt_operations' shouldn't really be part of the KMI, as
there's no reason for loadable modules to use it. However, due to the
way MODVERSIONS calculates symbol CRCs by recursively dereferencing
structures, changes to 'struct fscrypt_operations' affect the CRCs of
KMI functions exported from certain core kernel files such as
fs/dcache.c. That brings it in-scope for the KMI freeze.
Therefore, add some reserved fields to this struct for LTS updates.

SoCs featuring peripherals that can issue non-coherent DMA traffic
beyond the point of coherency (PoC) present multiple challenges for the
DMA-API implementation in Linux. Many of these challenges can be
overcome by suitable configuration of the interconnect, however the
presence of a cacheable alias for non-cacheable buffers can still lead
to coherence issues arising when stale clean lines are back-snooped from
the cache hierarchy to satisfy a non-cacheable transaction at the PoC.
Removing all cacheable aliases on a case-by-cases basis is both
error-prone and expensive. Instead, leverage the stage-2 identity
mapping installed by pKVM to enforce consistent cacheability for all
stage-1 aliases.

one of secondary device is set as ro, later update will cause panic, so

The root cause is: after cp_error is set, f2fs_submit_merged_ipu_write()
in f2fs_write_single_data_page() tries to flush IPU bio in cache, however
f2fs_submit_merged_ipu_write() missed to check validity of @bio parameter,
result in submitting random cached bio which belong to other IO context,
then it will cause use-after-free issue, fix it by adding additional
validity check.

Meanwhile, it removes f2fs_hw_is_readonly() check condition in:

- f2fs_convert_inline_inode()
As it has checked f2fs_readonly() condition, and if f2fs' devices

The greybus loopback test tool does not belong burried down in a
driver-specific directory. If it is needed, it should be somewhere
else, like in the testing directory. But as the loopback driver is
probably never going to be merged out of the staging directory, let's
just delete the test alltogether for now. If it's needed in the future,
it can be brought back with a revert.
Also, having an Android.mk file in the kernel source tree breaks some
Android build systems when trying to build from a read-only source tree,
the report of which prompted this being a good reason to remove it as
well.

As a fail-safe mechanism, disable pKVM module loading after the IOMMU
init is complete. This intends to make sure nothing can be loaded after
the IOMMU driver is ready, in case a vendor would forget to call
__pkvm_close_module_registration

Factor out the logic for setting the SVE vector length at the
hypervisor in pKVM to the maximum hardware supported value when
saving and restoring host SVE state.
This shares common code, and elides an unused variable warning
when SVE is not configured.

pKVM module loading is disabled by rejecting the HVCs. This is a problem
for kvm_call_hyp_nvhe(__pkvm_alloc_module_va). First a WARN will be
trigger, then the res.a1 being very much likely non 0 the error will
not be caught. The loading would then proceed (even though no EL2 code
will be actually loaded).
Fix this behaviour by catching when the HVC is blocked, so the user gets
a meaningful error returned and the driver is not half-loaded.

commit 0482c34ec6 upstream.
ucsi_init() which runs from a workqueue sets ucsi->connector and
on an error will clear it again.
ucsi->connector gets dereferenced by ucsi_resume(), this checks for
ucsi->connector being NULL in case ucsi_init() has not finished yet;
or in case ucsi_init() has failed.
ucsi_init() setting ucsi->connector and then clearing it again on
an error creates a race where the check in ucsi_resume() may pass,
only to have ucsi->connector free-ed underneath it when ucsi_init()
hits an error.
Fix this race by making ucsi_init() store the connector array in
a local variable and only assign it to ucsi->connector on success.

[ Upstream commit 4fb877aaa1 ]
Fix bug in btf_dump's logic of determining if a given struct type is
packed or not. The notion of "natural alignment" is not needed and is
even harmful in this case, so drop it altogether. The biggest difference
in btf_is_struct_packed() compared to its original implementation is
that we don't really use btf__align_of() to determine overall alignment
of a struct type (because it could be 1 for both packed and non-packed
struct, depending on specifci field definitions), and just use field's
actual alignment to calculate whether any field is requiring packing or
struct's size overall necessitates packing.
Add two simple test cases that demonstrate the difference this change
would make.

[ Upstream commit ea2ce1ba99 ]
Turns out that btf_dump API doesn't handle a bunch of tricky corner
cases, as reported by Per, and further discovered using his testing
Python script ([0]).
This patch revamps btf_dump's padding logic significantly, making it
more correct and also avoiding unnecessary explicit padding, where
compiler would pad naturally. This overall topic turned out to be very
tricky and subtle, there are lots of subtle corner cases. The comments
in the code tries to give some clues, but comments themselves are
supposed to be paired with good understanding of C alignment and padding
rules. Plus some experimentation to figure out subtle things like
whether `long :0;` means that struct is now forced to be long-aligned
(no, it's not, turns out).
Anyways, Per's script, while not completely correct in some known
situations, doesn't show any obvious cases where this logic breaks, so
this is a nice improvement over the previous state of this logic.
Some selftests had to be adjusted to accommodate better use of natural
alignment rules, eliminating some unnecessary padding, or changing it to
`type: 0;` alignment markers.
Note also that for when we are in between bitfields, we emit explicit
bit size, while otherwise we use `: 0`, this feels much more natural in
practice.
Next patch will add few more test cases, found through randomized Per's
script.
