cb23389a24 ARM: bcm: Fix refcount leak in bcm_kona_smc_init
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

In brcmstb_init_sram, it pass dn to of_address_to_resource(),
of_address_to_resource() will call of_find_device_by_node() to take

efedd01de4 KVM: arm64: Warn if accessing timer pending state outside of vcpu context
A recurrent bug in the KVM/arm64 code base consists in trying to
access the timer pending state outside of the vcpu context, which
makes zero sense (the pending state only exists when the vcpu
is loaded).

In order to avoid more embarassing crashes and catch the offenders
red-handed, add a warning to kvm_arch_timer_get_input_level() and
return the state as non-pending. This avoids taking the system down,
and still helps tracking down silly bugs.

98432ccdec KVM: arm64: Replace vgic_v3_uaccess_read_pending with vgic_uaccess_read_pending
Now that GICv2 has a proper userspace accessor for the pending state,
switch GICv3 over to it, dropping the local version, moving over the
specific behaviours that CGIv3 requires (such as the distinction
between pending latch and line level which were never enforced
with GICv2).

We also gain extra locking that isn't really necessary for userspace,
but that's a small price to pay for getting rid of superfluous code.

6cd88243c7 KVM: x86: do not report a vCPU as preempted outside instruction boundaries
If a vCPU is outside guest mode and is scheduled out, it might be in the
process of making a memory access.  A problem occurs if another vCPU uses
the PV TLB flush feature during the period when the vCPU is scheduled
out, and a virtual address has already been translated but has not yet
been accessed, because this is equivalent to using a stale TLB entry.

To avoid this, only report a vCPU as preempted if sure that the guest
is at an instruction boundary.  A rescheduling request will be delivered
to the host physical CPU as an external interrupt, so for simplicity
consider any vmexit *not* instruction boundary except for external
interrupts.

It would in principle be okay to report the vCPU as preempted also
if it is sleeping in kvm_vcpu_block(): a TLB flush IPI will incur the
vmentry/vmexit overhead unnecessarily, and optimistic spinning is
also unlikely to succeed.  However, leave it for later because right
now kvm_vcpu_check_block() is doing memory accesses.  Even
though the TLB flush issue only applies to virtual memory address,
it's very much preferrable to be conservative.

54aa83c901 KVM: x86: do not set st->preempted when going back to user space
Similar to the Xen path, only change the vCPU's reported state if the vCPU
was actually preempted.  The reason for KVM's behavior is that for example
optimistic spinning might not be a good idea if the guest is doing repeated
exits to userspace; however, it is confusing and unlikely to make a difference,
because well-tuned guests will hardly ever exit KVM_RUN in the first place.

96eca145cb zonefs: Do not ignore explicit_open with active zone limit
A zoned device may have no limit on the number of open zones but may
have a limit on the number of active zones it can support. In such
case, the explicit_open mount option should not be ignored to ensure
that the open() system call activates the zone with an explicit zone
open command, thus guaranteeing that the zone can be written.

Enforce this by ignoring the explicit_open mount option only for
devices that have both the open and active zone limits equal to 0.

5c95fe8b02 LoongArch: Remove MIPS comment about cycle counter
This comment block was taken originally from the MIPS architecture code,
where indeed there are particular assumptions one can make regarding SMP
and !SMP and cycle counters. On LoongArch, however, the rdtime family of
functions is always available. As Xuerui wrote:

    The rdtime family of instructions is in fact guaranteed to be
    available on LoongArch; LoongArch's subsets all contain them, even
    the 32-bit "Primary" subset intended for university teaching -- they
    provide the rdtimeh.w and rdtimel.w pair of instructions that access
    the same 64-bit counter.

So this commit simply removes the incorrect comment block.

120f1d95ef scsi: mpt3sas: Fix out-of-bounds compiler warning
I'm facing this warning when building for the parisc64 architecture:

drivers/scsi/mpt3sas/mpt3sas_base.c: In function ‘_base_make_ioc_operational’:
drivers/scsi/mpt3sas/mpt3sas_base.c:5396:40: warning: array subscript ‘Mpi2SasIOUnitPage1_t {aka struct _MPI2_CONFIG_PAGE_SASIOUNIT_1}[0]’ is partly outside array bounds of ‘unsigned char[20]’ [-Warray-bounds]
 5396 |             (le16_to_cpu(sas_iounit_pg1->SASWideMaxQueueDepth)) ?
drivers/scsi/mpt3sas/mpt3sas_base.c:5382:26: note: referencing an object of size 20 allocated by ‘kzalloc’
 5382 |         sas_iounit_pg1 = kzalloc(sz, GFP_KERNEL);
      |                          ^~~~~~~~~~~~~~~~~~~~~~~

The problem is, that only 20 bytes are allocated with kmalloc(), which is
sufficient to hold the bytes which are needed.  Nevertheless, gcc complains
because the whole Mpi2SasIOUnitPage1_t struct is 32 bytes in size and thus
doesn't fit into those 20 bytes.

This patch simply allocates all 32 bytes (instead of 20) and thus avoids
the warning. There is no functional change introduced by this patch.

While touching the code I cleaned up to calculation of max_wideport_qd,
max_narrowport_qd and max_sata_qd to make it easier readable.

Test successfully tested on a HP C8000 PA-RISC workstation with 64-bit
kernel.

336d636154 scsi: lpfc: Fix port stuck in bypassed state after LIP in PT2PT topology
After issuing a LIP, a specific target vendor does not ACC the FLOGI that
lpfc sends.  However, it does send its own FLOGI that lpfc ACCs.  The
target then establishes the port IDs by sending a PLOGI.  lpfc PLOGI_ACCs
and starts the RPI registration for DID 0x000001.  The target then sends a
LOGO to the fabric DID.  lpfc is currently treating the LOGO from the
fabric DID as a link down and cleans up all the ndlps.  The ndlp for DID
0x000001 is put back into NPR and discovery stops, leaving the port in
stuck in bypassed mode.

Change lpfc behavior such that if a LOGO is received for the fabric DID in
PT2PT topology skip the lpfc_linkdown_port() routine and just move the
fabric DID back to NPR.

b1b3440f43 scsi: lpfc: Resolve NULL ptr dereference after an ELS LOGO is aborted
A use-after-free crash can occur after an ELS LOGO is aborted.

Specifically, a nodelist structure is freed and then
ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the
discovery state machine is mistakenly called a second time with
NLP_EVT_DEVICE_RM argument.

Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a
nodelist structure.
