In mlx5e_open_channel CQs must be created before napi is enabled.
Here we move the XDP CQ creation to satisfy that fact.
mlx5e_close_channel is already working according to the right order.

In case of mlx5e_open_rq fails the error handling will jump to
label err_close_xdp_sq and will try to close the xdp_sq unconditionally.
xdp_sq is valid only in case of XDP use cases, i.e priv->xdp_prog is
not null.
To fix this in this patch we test xdp_sq validity prior to closing it.
In addition we now close the xdp_sq.cq as well.

In cases like IPI, we could be queueing an interrupt for a VCPU
that is already running and is not about to exit, because the
VCPU has entered the VM with the interrupt pending and would
not trap on EOI'ing that interrupt. This could result to delays
in interrupt deliveries or even loss of interrupts.
To guarantee prompt interrupt injection, here we have to try to
kick the VCPU.

In our VGIC implementation we limit the number of SPIs to a number
that the userland application told us. Accordingly we limit the
allocation of memory for virtual IRQs to that number.
However in our MMIO dispatcher we didn't check if we ever access an
IRQ beyond that limit, leading to out-of-bound accesses.
Add a test against the number of allocated SPIs in check_region().
Adjust the VGIC_ADDR_TO_INT macro to avoid an actual division, which
is not implemented on ARM(32).

single CPU
Architecturally, TLBs are private to the (physical) CPU they're
associated with. But when multiple vcpus from the same VM are
being multiplexed on the same CPU, the TLBs are not private
to the vcpus (and are actually shared across the VMID).
Let's consider the following scenario:
- vcpu-0 maps PA to VA
- vcpu-1 maps PA' to VA
If run on the same physical CPU, vcpu-1 can hit TLB entries generated
by vcpu-0 accesses, and access the wrong physical page.
The solution to this is to keep a per-VM map of which vcpu ran last
on each given physical CPU, and invalidate local TLBs when switching
to a different vcpu from the same VM.

The AC'97 standard defines paging support for the register range 0x60-0x6f.
Meaning registers in this window are mapped to different physical registers
depending on the setting of the page select register (0x24).
The stac9766 implements support for switching between page 0 and page 1
depending on the addressed register. But the driver never accesses any
registers from page 1, in addition page 0 is the page selected by default.
Considering the development history it is unlikely that the driver will see
any new features that require paging support. Removing the paging support
makes transitioning the driver to regmap a bit more straight forward.
The default register value table is update to contain the values from page
0, rather than page 1.

Rename the ABI struct and type because they are for configuring physical
DAIs, not only backend DAIs since users may not need DPCM:
- Rename struct snd_soc_tplg_be_dai to snd_soc_tplg_dai.
- Rename type SND_SOC_TPLG_TYPE_BE_DAI to SND_SOC_TPLG_TYPE_DAI.
This code refactoring is backward compatible because:
- Both layout of the struct and type value has no change. Kernel can
find the same type value and map to same data layout.
- This struct is not in ABI v4 at all. Now the user space uses ABI v4.

Define the API to find an existing DAI link of the soc card by matching
the ID, name and stream name.
Some cards may use unique ID for each DAI link, so matching ID is enough,
and name or stream name are not necessary. But user need to specify name
or stream name as well if not sure whether link ID is unique since most
cards use 0 as the default link ID.
Topology can use this API to find an existing BE link and configure it.

The following fields are added to physical link configuration struct
(snd_soc_tplg_link_config) in ABI v5:
- name and stream name
Topology will use them to find an existing physical link and configure
it.
- HW configurations
Define the types and ABI struct for runtime supported hardware configs
of physical DAI links, e.g. audio hardware formats. The default HW
config ID will help topology to find the DAI format to set on init.
Topology provides this as a fallback if such HW settings are not
available in ACPI or device tree, to avoid hard code in drivers. It's
only for config items that can be programmed by SW or FW, not for
physical things like link connections or GPIO used for HP etc.
- flags and private data
The flags will be used to configure an existing physical DAI link.
The private data is reserved for future extension.
NOTE: Current kernel has no support for physical links. A later patch
will add support for configuring physical links and make the support
backward compatible for ABI v4.

If VRAM allocation fails, the error handling path crashes in
msm_drm_uninit(). The following changes are made to fix this:
msm_gem_shrinker_cleanup() is fixed to unregister the shrinker only
if it was init-ed in the first place.
Before calling kms->funcs->destroy(), we check if kms->funcs is also
non-NULL. This is needed for MDP5, since during msm_drm_int(), priv->kms
becomes non-NULL early, but msm_kms_init() is called on it only later
in mdp5_kms_init().

commit cfa636886033 ("clk: sunxi: factors: Consolidate get_factors
parameters into a struct") introduced a regression for m factor
computation in sun4i_get_apb1_factors function.
The old code reassigned the "parent_rate" parameter to the targeted
divisor value and was buggy for the returned frequency but not for the
computed factors. Now, returned frequency is good but m factor is
incorrectly computed (its max value 31 is always set resulting in a
significantly slower frequency than the requested one...)
This patch simply restores the original proper computation for m while
keeping the good changes for returned rate.

When low memory doesn't reach HIGHMEM_START (e.g. up to 256MB at PA=0 is
common) and highmem is present above HIGHMEM_START (e.g. on Malta the
RAM overlayed by the IO region is aliased at PA=0x90000000), max_low_pfn
will be initially calculated very large and then clipped down to
HIGHMEM_START.
This causes crashes when reading /sys/kernel/mm/page_idle/bitmap
(i.e. CONFIG_IDLE_PAGE_TRACKING=y) when highmem is disabled. pfn_valid()
will compare against max_mapnr which is derived from max_low_pfn when
there is no highend_pfn set up, and will return true for PFNs right up
to HIGHMEM_START, even though they are beyond the end of low memory and
no page structs will actually exist for these PFNs.
This is fixed by skipping high memory regions when initially calculating
max_low_pfn if highmem is disabled, so it doesn't get clipped too high.
We also clip regions which overlap the highmem boundary when highmem is
disabled, so that max_pfn doesn't extend into highmem either.

in a signal context with MIPS I hardware.
Use the S.D and L.D assembly macros to have pairs of SWC1 instructions
and pairs of LWC1 instructions produced, respectively, in an arrangement
which makes the memory representation of floating-point data passed
compatible with that used by hardware SDC1 and LDC1 instructions, where
available, regardless of the hardware endianness used. This matches the
layout used by r4k_fpu.S, ensuring run-time compatibility for MIPS I
software across all o32 hardware platforms.
Define an EX2 macro to handle exceptions from both hardware instructions
implicitly produced from S.D and L.D assembly macros.

Sanitize FCSR Cause bit handling, following a trail of past attempts:
* commit 4249548454f7 ("MIPS: ptrace: Fix FP context restoration FCSR
regression"),
* commit 443c44032a54 ("MIPS: Always clear FCSR cause bits after
emulation"),
* commit 64bedffe4968 ("MIPS: Clear [MSA]FPE CSR.Cause after
notify_die()"),
* commit b1442d39fac2 ("MIPS: Prevent user from setting FCSR cause
bits"),
* commit b54d2901517d ("Properly handle branch delay slots in connection
with signals.").
Specifically do not mask these bits out in ptrace(2) processing and send
a SIGFPE signal instead whenever a matching pair of an FCSR Cause and
Enable bit is seen as execution of an affected context is about to
resume. Only then clear Cause bits, and even then do not clear any bits
that are set but masked with the respective Enable bits. Adjust Cause
bit clearing throughout code likewise, except within the FPU emulator
proper where they are set according to IEEE 754 exceptions raised as the
operation emulated executed. Do so so that any IEEE 754 exceptions
subject to their default handling are recorded like with operations
executed by FPU hardware.

handle reboots, but incorrectly used the value 0x4d rather than 0x42 as
the magic to write to the reboot register.
I also incorrectly believed that syscon/regmap would default to native
endianness, but this isn't the case. Force this by specifying with a
native-endian property in the devicetree.

Provide a default implementation of mips_cpc_default_phys_base() which
simply returns 0, and adjust mips_cpc_phys_base() to allow for
mips_cpc_default_phys_base() returning 0. This allows kernels which
include CPC support to be built without platform code & simply ignore
the CPC if it wasn't already enabled by the bootloader.
This fixes link failures such as the following from generic defconfigs:
arch/mips/built-in.o: In function `mips_cpc_phys_base':
arch/mips/kernel/mips-cpc.c:47: undefined reference to `mips_cpc_default_phys_base'
[ralf@linux-mips.org: changed prototype for coding style compliance.]

cgroupstats_cmd_get_policy is [CGROUPSTATS_CMD_ATTR_MAX+1],
taskstats_cmd_get_policy[TASKSTATS_CMD_ATTR_MAX+1],
but their family.maxattr is TASKSTATS_CMD_ATTR_MAX.
CGROUPSTATS_CMD_ATTR_MAX is less than TASKSTATS_CMD_ATTR_MAX,
so we could end up accessing out-of-bound.
Change cgroupstats_cmd_get_policy to TASKSTATS_CMD_ATTR_MAX+1,
this is safe because the rest are initialized to 0's.

In __genl_register_family(), when genl_validate_assign_mc_groups()
fails, we forget to free the memory we possibly allocate for
family->attrbuf.
Note, some callers call genl_unregister_family() to clean up
on error path, it doesn't work because the family is inserted
to the global list in the nearly last step.

The A31 has a similar codec to the A10/A20. The PCM parts are very
similar, with different register offsets. The analog paths are very
different. There are more inputs and outputs. The ADC mux has been
replaced with a proper mixer.
This patch adds support for the basic playback path of the A31 codec,
from the DAC to the headphones. Headphone detection, microphone,
signaling, other inputs/outputs and capture will be added later.
