The following patches resulted in deferring crash kernel reservation to
mem_init(), mainly aimed at platforms with DMA memory zones (no IOMMU),
in particular Raspberry Pi 4.
commit 1a8e1cef7603 ("arm64: use both ZONE_DMA and ZONE_DMA32")
commit 8424ecdde7df ("arm64: mm: Set ZONE_DMA size based on devicetree's dma-ranges")
commit 0a30c53573b0 ("arm64: mm: Move reserve_crashkernel() into mem_init()")
commit 2687275a5843 ("arm64: Force NO_BLOCK_MAPPINGS if crashkernel reservation is required")
Above changes introduced boot slowdown due to linear map creation for
all the memory banks with NO_BLOCK_MAPPINGS, see discussion[1]. The proposed
changes restore crash kernel reservation to earlier behavior thus avoids
slow boot, particularly for platforms with IOMMU (no DMA memory zones).
Tested changes to confirm no ~150ms boot slowdown on our SoC with IOMMU
and 8GB memory. Also tested with ZONE_DMA and/or ZONE_DMA32 configs to confirm
no regression to deferring scheme of crash kernel memory reservation.
In both cases successfully collected kernel crash dump.

In this situation (VLAN filtering disabled on br0):
br0.10
/
br0
/ \
swp0 swp1
When a frame is transmitted from the VLAN upper, the bridge will send
it down to one of the switch ports with forward offloading
enabled. This will cause tag_dsa to generate a FORWARD tag. Before
this change, that tag would have it's VID set to 10, even though VID
10 is not loaded in the VTU.
Before the blamed commit, the frame would trigger a VTU miss and be
forwarded according to the PVT configuration. Now that all fabric
ports are in 802.1Q secure mode, the frame is dropped instead.
Therefore, restrict the condition under which we rewrite an 802.1Q tag
to a DSA tag. On standalone port's, reuse is always safe since we will
always generate FROM_CPU tags in that case. For bridged ports though,
we must ensure that VLAN filtering is enabled, which in turn
guarantees that the VID in question is loaded into the VTU.

Commit 18107f8a2df6 ("arm64: Support execute-only permissions with
Enhanced PAN") re-introduced execute-only permissions when EPAN is
available. When EPAN is not available, arch_filter_pgprot() is supposed
to change a PAGE_EXECONLY permission into PAGE_READONLY_EXEC. However,
if BTI or MTE are present, such check does not detect the execute-only
pgprot in the presence of PTE_GP (BTI) or MT_NORMAL_TAGGED (MTE),
allowing the user to request PROT_EXEC with PROT_BTI or PROT_MTE.
Remove the arch_filter_pgprot() function, change the default VM_EXEC
permissions to PAGE_READONLY_EXEC and update the protection_map[] array
at core_initcall() if EPAN is detected.

This rewrites the former text based AB8500 bindings in YAML.
When the AB8500 bindings were first written (in 2012) we
were not strict on some things and node names were definitely
not standardized.
This patch uses standard node names to most of the subnodes
on the AB8500 and is accompanied by another patch fixing
all the DTS files to conform to this.
The bindings are not as perfect as newly written bindings
would be, it is a best effort to deal with the legacy.

Returning a non-zero value in an i2c remove callback results in the i2c
core emitting a very generic error message ("remove failed (-ESOMETHING),
will be ignored") and as the message indicates not further error handling
is done.
Instead emit a more specific error message and then return zero in
.remove().
The long-term goal is to make the i2c remove prototype return void, making
all implementations return 0 is preparatory work for this change.

For the CRC PMIC we end up with multiple IRQ domains with the same fwnode.
One for the irqchip which demultiplexes the actual PMIC interrupt into
interrupts for the various cells (known as the level 1 interrupts);
And 2 more for the irqchips which are part of the crystal_cove_gpio
and crystal_cove_charger cells.
This leads to the following error being printed when
CONFIG_GENERIC_IRQ_DEBUGFS is enabled:
debugfs: File '\_SB.I2C7.PMIC' in directory 'domains' already present!
Set the bus token of the main IRQ domain to DOMAIN_BUS_NEXUS to avoid
this error, this also allows irq_find_matching_fwspec() to find the
right domain if necessary.
Note all 3 domain registering drivers need to set the IRQ domain bus token.
This is necessary because the IRQ domain code defaults to creating
the debugfs dir with just the fwnode name and then renames it when
the bus token is set. So each one starts with the same default name and
all 3 must be given a different name to avoid problems when one of the
other drivers loads and starts with the same default name.

The Crystal Cove PMIC has a pin which can be used to connect the IRQ of
an external charger IC. On some boards this is used and we need to have
a cell for this, with a driver which creates its own irqchip with
a single IRQ for the charger driver to consume.
The charger driver cannot directly consume the IRQ from the MFD level
irqchip because the PMIC has 2 levels of interrupts and the second
level interrupt status register, which is handled by the cell drivers,
needs to have the IRQ acked to avoid an IRQ storm.

lengths against the wrong algorithm properties. Fix it to check against

Probably this wasn't noticed before because for all asymmetric keys of
the "public_key" subtype, max_data_size == max_sig_size == max_enc_size
== max_dec_size. However, this isn't necessarily true for the
"asym_tpm" subtype (it should be, but it's not strictly validated). Of
course, future key types could have different values as well.

When an invalid (non existing) handle is used in a TPM command,
that uses the resource manager interface (/dev/tpmrm0) the resource
manager tries to load it from its internal cache, but fails and
the tpm_dev_transmit returns an -EINVAL error to the caller.
The existing async handler doesn't handle these error cases
currently and the condition in the poll handler never returns
mask with EPOLLIN set.
The result is that the poll call blocks and the application gets stuck
until the user_read_timer wakes it up after 120 sec.
Change the tpm_dev_async_work function to handle error conditions
returned from tpm_dev_transmit they are also reflected in the poll mask
and a correct error code could passed back to the caller.

Determine an available PCR bank to be used by a test case by querying the
capability TPM2_GET_CAP. The TPM2 returns TPML_PCR_SELECTIONS that
contains an array of TPMS_PCR_SELECTIONs indicating available PCR banks
and the bitmasks that show which PCRs are enabled in each bank. Collect
the data in a dictionary. From the dictionary determine the PCR bank that
has the PCRs enabled that the test needs. This avoids test failures with
TPM2's that either to not have a SHA-1 bank or whose SHA-1 bank is
disabled.

The current implementation of the async flip wm0/ddb optimization
does not work at all. The biggest problem is that we skip the
whole intel_pipe_update_{start,end}() dance and thus never actually
complete the commit that is trying to do the wm/ddb change.
To fix this we need to move the do_async_flip flag to the crtc
state since we handle commits per-pipe, not per-plane.
Also since all planes can now be included in the first/last
"async flip" (which gets converted to a sync flip to do the
wm/ddb mangling) we need to be more careful when checking if
the plane state is async flip comptatible. Only planes doing
the async flip should be checked and other planes are perfectly
fine not adhereing to any async flip related limitations.
However for subsequent commits which are actually going do the
async flip in hardware we want to make sure no other planes
are in the state. That should never happen assuming we did our
job correctly, so we'll toss in a WARN to make sure we catch
any bugs here.

Since the async flip state check is done very late and
thus it can see potentially all the planes in the state
(due to the wm/ddb optimization) we need to move the
"can the requested plane do async flips at all?" check
much earlier. For this purpose we introduce
intel_async_flip_check_uapi() that gets called early during
the atomic check.
And for good measure we'll throw in a couple of basic checks:
- is the crtc active?
- was a modeset flagged?
- is+was the plane enabled?
Though atm all of those should be guaranteed by the fact
that the async flip can only be requested through the legacy
page flip ioctl.

data_rate==0 no longer means a plane is disabled, it could
also mean we want to use the minimum ddb allocation for it.
Hence we can't bail out early during ddb allocation or
else we'll simply forget to allocate any ddb for such planes.

bigjoiner_pipes==0 leads bigjoiner_master_pipe() to
do BIT(ffs(0)-1) which is undefined behaviour. The code should
actually still work fine since the only place we provoke
that is intel_crtc_bigjoiner_slave_pipes() and it'll bitwise
AND the result with 0, so doesn't really matter what we get
out of bigjoiner_master_pipe(). But best not provoke undefined
behaviour anyway.
