The function in net core, register_netdevice(), may fail with vport's
destruction callback either invoked or not. After commit 309b66970ee2
("net: openvswitch: do not free vport if register_netdevice() is failed."),
the duty to destroy vport is offloaded from the driver OTOH, which ends
up in the memory leak reported.
It is fixed by releasing vport unless device is registered successfully.
To do that, the callback assignment is defered until device is registered.

When firmware indicates that driver needs to invoke firmware reset
which is common for both error recovery and live firmware reset path,
driver needs a different time to wait before polling for firmware

Modify the wait time to fw_reset_min_dsecs, which is initialised to
correct timeout for error recovery and firmware reset.

The current code that rounds up the NVRAM parameter bit size to the next
byte size for the devlink parameter is not always correct. The MSIX
devlink parameters are 4 bytes and we don't get the correct size
using this method.
Fix it by adding a new dl_num_bytes member to the bnxt_dl_nvm_param
structure which statically provides bytesize information according
to the devlink parameter type definition.

After further debugging it turns out that we walk kallsyms while in parallel
we tear down a BPF program which contains subprograms that have been JITed
though the program itself has not been fully exposed and is eventually bailing
out with error.
The bpf_prog_kallsyms_del_subprogs() in bpf_prog_load()'s error path removes
the symbols, however, bpf_prog_free() tears down the JIT memory too early via
scheduled work. Instead, it needs to properly respect RCU grace period as the
kallsyms walk for BPF is under RCU.
Fix it by refactoring __bpf_prog_put()'s tear down and reuse it in our error
path where we defer final destruction when we have subprogs in the program.

The issue is in drivers/infiniband/core/uverbs_std_types_cq.c in the
UVERBS_HANDLER(UVERBS_METHOD_CQ_CREATE) function. We check that:
if (attr.comp_vector >= attrs->ufile->device->num_comp_vectors) {
But we don't check if "attr.comp_vector" is negative. It could
potentially lead to an array underflow. My concern would be where
cq->vector is used in the create_cq() function from the cxgb4 driver.
And really "attr.comp_vector" is appears as a u32 to user space so that's
the right type to use.

If the "virtualize APIC accesses" VM-execution control is set in the
VMCS, the APIC virtualization hardware is triggered when a page walk
in VMX non-root mode terminates at a PTE wherein the address of the 4k
page frame matches the APIC-access address specified in the VMCS. On
hardware, the APIC-access address may be any valid 4k-aligned physical
address.
KVM's nVMX implementation enforces the additional constraint that the
APIC-access address specified in the vmcs12 must be backed by
a "struct page" in L1. If not, L0 will simply clear the "virtualize
APIC accesses" VM-execution control in the vmcs02.
The problem with this approach is that the L1 guest has arranged the
vmcs12 EPT tables--or shadow page tables, if the "enable EPT"
VM-execution control is clear in the vmcs12--so that the L2 guest
physical address(es)--or L2 guest linear address(es)--that reference
the L2 APIC map to the APIC-access address specified in the
vmcs12. Without the "virtualize APIC accesses" VM-execution control in
the vmcs02, the APIC accesses in the L2 guest will directly access the
APIC-access page in L1.
When there is no mapping whatsoever for the APIC-access address in L1,
the L2 VM just loses the intended APIC virtualization. However, when
the APIC-access address is mapped to an MMIO region in L1, the L2
guest gets direct access to the L1 MMIO device. For example, if the
APIC-access address specified in the vmcs12 is 0xfee00000, then L2
gets direct access to L1's APIC.
Since this vmcs12 configuration is something that KVM cannot
faithfully emulate, the appropriate response is to exit to userspace
with KVM_INTERNAL_ERROR_EMULATION.

8-letter strings representing ARC perf events are stores in two
32-bit registers as ASCII characters like that: "IJMP", "IALL", "IJMPTAK" etc.
And the same order of bytes in the word is used regardless CPU endianness.
Which means in case of big-endian CPU core we need to swap bytes to get
the same order as if it was on little-endian CPU.
Otherwise we're seeing the following error message on boot:
------------------------->8----------------------
ARC perf : 8 counters (32 bits), 40 conditions, [overflow IRQ support]

------------------------->8----------------------
What happens here we're trying to register more than one raw perf event
with the same name "PMJI". Why? Because ARC perf events are 4 to 8 letters
and encoded into two 32-bit words. In this particular case we deal with 2
events:
* "IJMP____" which counts all jump & branch instructions
* "IJMPC___" which counts only conditional jumps & branches
Those strings are split in two 32-bit words this way "IJMP" + "____" &
"IJMP" + "C___" correspondingly. Now if we read them swapped due to CPU core
being big-endian then we read "PMJI" + "____" & "PMJI" + "___C".
And since we interpret read array of ASCII letters as a null-terminated string
on big-endian CPU we end up with 2 events of the same name "PMJI".

Commit:
8a58ddae2379 ("perf/core: Fix exclusive events' grouping")
allows CAP_EXCLUSIVE events to be grouped with other events. Since all
of those also happen to be AUX events (which is not the case the other
way around, because arch/s390), this changes the rules for stopping the
output: the AUX event may not be on its PMU's context any more, if it's
grouped with a HW event, in which case it will be on that HW event's
context instead. If that's the case, munmap() of the AUX buffer can't
find and stop the AUX event, potentially leaving the last reference with
the atomic context, which will then end up freeing the AUX buffer. This
will then trip warnings:
Fix this by using the context's PMU context when looking for events
to stop, instead of the event's PMU context.

Commit bf653b78f960 ("KVM: vmx: Introduce handle_unexpected_vmexit
and handle WAITPKG vmexit") introduced specialized handling of
specific exit-reasons that should not be raised by CPU because
KVM configures VMCS such that they should never be raised.
However, since commit 7396d337cfad ("KVM: x86: Return to userspace
with internal error on unexpected exit reason"), VMX & SVM
exit handlers were modified to generically handle all unexpected
exit-reasons by returning to userspace with internal error.
Therefore, there is no need for specialized handling of specific
unexpected exit-reasons (This specialized handling also introduced
inconsistency for these exit-reasons to silently skip guest instruction
instead of return to userspace on internal-error).

total_ref_count++
free_percpu(perf_trace_buf[i])
perf_trace_buf[i] = NULL
Any subsequent call to perf_trace_event_reg() will observe total_ref_count > 0,
causing the perf_trace_buf to be always NULL. This can result in perf_trace_buf
getting accessed from perf_trace_buf_alloc() without being initialized. Acquiring
event_mutex in perf_kprobe_init() before calling perf_trace_event_init() should
fix this race.

The platform detection VMWARE_PORT macro uses the VMWARE_HYPERVISOR_PORT
definition, but expects it to be an integer. However, when it was moved
to the new vmware.h include file, it was changed to be a string to better
fit into the VMWARE_HYPERCALL set of macros. This obviously breaks the
platform detection VMWARE_PORT functionality.
Change the VMWARE_HYPERVISOR_PORT and VMWARE_HYPERVISOR_PORT_HB
definitions to be integers, and use __stringify() for their stringified
form when needed.

DaVinci fixes for v5.4
======================
* fix GPIO backlight support on DA850 by enabling the needed config
in davinci_all_defconfig. This is a fix because the driver and board
support got converted to use BACKLIGHT_GPIO driver, but defconfig update
is still missing in v5.4.
* fix for McBSP DMA on DM365

i.MX fixes for 5.4:
- Re-enable SNVS power key for imx6q-logicpd board which was accidentally
disabled by a SoC level change.
- Fix I2C switches on vf610-zii-scu4-aib board by specifying property
i2c-mux-idle-disconnect.
- A fix on imx-scu API that reads UID from firmware to avoid kernel NULL
pointer dump.
- A series from Anson to correct i.MX7 GPT and i.MX8 USDHC IPG clock.
- A fix on DRM_MSM Kconfig regression on i.MX5 by adding the option
explicitly into imx_v6_v7_defconfig.
- Fix ARM regulator states issue for zii-ultra board, which is impacting
stability of the board.
- A correction on CPU core idle state name for LayerScape LX2160A SoC.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes
Fixes for omaps for v5.4-rc cycle
More fixes for omap variants:
- Update more panel options in omap2plus_defconfig that got changed
as we moved to use generic LCD panels
- Remove unused twl_keypad for logicpd-torpedo-som to avoid boot
time warnings. This is only a cosmetic fix, but at least dmesg output
is now getting more readable after all the fixes to remove pointless
warnings
- Fix gpu_cm node name as we still have a non-standard node name
dependency for clocks. This should eventually get fixed by use
of domain specific compatible property
- Fix use of i2c-mux-idle-disconnect for m3874-iceboard
- Use level interrupt for omap4 & 5 wlcore to avoid lost edge
interrupts

This device is sold as 'ThinkPad USB-C Dock Gen 2 (40AS)'.
Chipset is RTL8153 and works with r8152.
Without this, the generic cdc_ether grabs the device, and the device jam
connected networks up when the machine suspends.
