As commit 559089e0a9 ("vmalloc: replace VM_NO_HUGE_VMAP with
VM_ALLOW_HUGE_VMAP"), the use of hugepage mappings for vmalloc
is an opt-in strategy, so it is saftly to support huge vmalloc
mappings on arm64, for now, it is used in kvmalloc() and
alloc_large_system_hash().

This harmless print provides a very easy way of knowing
if the modem is detected properly during probing.
Promote it to an informational print so no hassle is required
enabling kernel debugging info to obtain it.
The rationale here is that:
On a lot of low-storage embedded devices, extensive kernel
debugging info is not always present as this would
increase it's size to much causing partition size issues.

Removed the lpfc_fdmi_attr_entry and lpfc_fdmi_attr_def structures that had
a union causing unintentional zero padding, which required the usage of
__packed. They are replaced with explicit lpfc_fdmi_attr_u32,
lpfc_fdmi_attr_wwn, lpfc_fdmi_attr_fc4types, and lpfc_fdmi_attr_string
structure defines instead of living in a union. This rids of ambiguous
compiler zero padding, and entailed cleaning up bitwise endian
declarations.
As such, all FDMI attribute registration routines are replaced with generic
void *arg and handlers for each of the newly defined attribute structure
types.

On a PCI hotplug capable system, it is possible for scsi_device_put() to
happen after lpfc_pci_remove_one() is called. As a result, the
sdev->host->hostt->module dereference is for a previously freed memory
location because the phba structure containing the hostt template was
already freed when lpfc_pci_remove_one() returned.
Since the lpfc module is still loaded during power slot disable, all
scsi_host_templates should be declared as part of the global data segment
instead of inside the heap allocated phba structure. This way the
sdev->host->hostt memory area is always valid as long as the module is
loaded regardless if PCI hotplug dynamically allocates or frees phba
structures.
Move all scsi_host_templates in the phba structure to global variables.
Create a small helper routine to determine appropriate sg_tablesize during
shost allocation.

When a target makes the mistake of registering a FC4 type with the fabric,
but then rejects a PRLI of that type, the lpfc driver incorrectly retries
the PRLI causing multiple registrations with the transport. The driver

Sometimes VMID targets are not getting rediscovered after a port reset.
The iocb is not freed in lpfc_cmpl_ct_cmd_vmid(), which is the completion
function for the appid CT commands. So after a port reset, the count of
sges is less than the expected count of 250. This causes post reset
operation logic to fail and keep the port offline.
Fix by freeing the iocb and kref put for the lpfc_cmpl_ct_cmd_vmid() early
return cases.

When a FLOGI is received before we have issued our FLOGI, the ACC response
to the received FLOGI is issued with SID 2 instead of the expected fabric
controller SID. Certain target vendors ignore the malformed ACC with SID 2
and wait for a properly filled ACC with a fabric controller SID.
The lpfc_sli_prep_wqe() routine depends on the FC_PT2PT flag to fill in the
fabric controller SID when in PT2PT mode, but due to a previous commit the
flag was getting cleared. Fix by adding a check for the defer_flogi_acc
flag to know whether or not to clear the FC_PT2PT flag on link up.

The if statment check (prli_fc4_req & PRLI_NVME_TYPE) evaluates to true
when receiving a PRLI request for bogus FC4 type codes that happen to have
the 3rd or 5th bit set because PRLI_NVME_TYPE is 0x28. This leads to
sending a PRLI_NVME_ACC even for bogus FC4 type codes.

PRLI_NVME_ACC only for NVME type coded PRLI requests.

Going forwards, the intention is for GuC firmware files to be named
for their major version only and HuC firmware files to have no version
number in the name at all. This patch adds those entries for all
platforms that are officially GuC/HuC enabled.
Also, update the expected GuC version numbers to the latest firmware
release for those platforms.

The default target port group is always returned in the list of port
groups, even if the behaviour is unwanted, i.e. it has no members and
non-default port groups are primary port groups.
That violates SPC-4 "6.37 REPORT TARGET PORT GROUPS command":
Every target port group shall contain at least one target port. The
target port group descriptor shall include one target port descriptor for
each target port in the target port group.
This patch hides port groups with no ports in REPORT TARGET PORT GROUPS
response.

SAM-5 4.8.3 (SCSI target device with multiple SCSI ports structure)
obligates to set MULTIP bit when there's multiple SCSI target ports:
Each device server shall indicate the presence of multiple SCSI
target ports by setting the MULTIP bit to one in its standard
INQUIRY data (see SPC-4).
Set MULTIP bit automatically to indicate the presence of multiple SCSI
target ports within standard inquiry response data if there are
multiple target ports in all target port groups of the se_device.

In __qedf_probe(), if qedf->cdev is NULL which means
qed_ops->common->probe() failed, then the program will goto label err1, and
scsi_host_put() will free lport->host pointer. Because the memory qedf
points to is allocated by libfc_host_alloc(), it will be freed by
scsi_host_put(). However, the if statement below label err0 only checks
whether qedf is NULL but doesn't check whether the memory has been freed.
So a UAF bug can occur.
There are two ways to reach the statements below err0. The first one is
described as before, "qedf" should be set to NULL. The second one is goto
"err0" directly. In the latter scenario qedf hasn't been changed and it has
the initial value NULL. As a result the if statement is not reachable in
any situation.

Commit 9a073d4fbb ("soc: bcm: brcmstb: biuctrl: Add missing
of_node_put()") added what was thought to be a missing of_node_put() but
now causes a double of_node_put() to be called, once from
setup_hifcpubiuctrl_regs() and another time from brcmstb_biuctrl_init().
Ensure that setup_hifcpubiuctrl_regs() is not calling of_node_put()
since it is not obvious it does that on one of its parameters.

Due to change to switch to use lock_sock inside rfcomm_sk_state_change
the socket shutdown/release procedure can cause a deadlock:
rfcomm_sock_shutdown():
lock_sock();
__rfcomm_sock_close():
rfcomm_dlc_close():
__rfcomm_dlc_close():
rfcomm_dlc_lock();
rfcomm_sk_state_change():
lock_sock();
To fix this when the call __rfcomm_sock_close is now done without
holding the lock_sock since rfcomm_dlc_lock exists to protect
the dlc data there is no need to use lock_sock in that code path.

Now that everything except StrongARM is unified under
CONFIG_ARCH_MULTIPLATFORM, the option is rather meaningless
in its current form.
Rework the Kconfig logic to make this useful again, similar
to the way that RISC-V has CONFIG_NONPORTABLE (with the
opposite polarity), this now controls the visibility of
options that get in the way of building generic kernels,
while allowing custom kernels.
One side-effect is that 'randconfig' builds now rarely hit
strongarm machines, rather than testing them three quarters
of the time.

Small set of changes in preparation to add support for FF-A v1.1
specification later. It mainly contains:
1. Splitting up ffa_ops into different categories namely information,
message and memory. It helps to make info and memory operations
independent from ffa_device so thata generic memory management
module can use it without specific ffa_dev.
2. Adds support for querying FF-A features and use the same to detect
the support for 64-bit operations.
3. Adds v1.1 get_partition_info support and use the same to set up
32-bit execution mode flag automatically.
4. Adds pointer to the ffa_dev_ops in struct ffa_dev and drop
ffa_dev_ops_get() which enables to drop ffa_ops in optee_ffa
structure using ffa_dev->ops directly. Additionally ffa_dev_ops is
renamed as ffa_ops.
