Since x86 instruction decoder is not only for kprobes,
it should be tested when the insn.c is compiled.

When the 'start' parameter is >= 0xFF000000 on 32-bit
systems, or >= 0xFFFFFFFF'FF000000 on 64-bit systems,
fill_gva_list() gets into an infinite loop.
With such inputs, 'cur' overflows after adding HV_TLB_FLUSH_UNIT
and always compares as less than end. Memory is filled with
guest virtual addresses until the system crashes.
Fix this by never incrementing 'cur' to be larger than 'end'.

Maxim 77802 PMIC is a main PMIC for the following Exynos5 based boards:

Commit aff138bf8e37 ("ARM: dts: exynos: Add TMU nodes regulator supply
for Peach boards") assigned LDO10 to Exynos Thermal Measurement Unit,
but it turned out that it supplies also some other critical parts and
board freezes/crashes when it is turned off.
The mentioned commit made Exynos TMU a consumer of that regulator and in
typical case Exynos TMU driver keeps it enabled from early boot. However
there are such configurations (example is multi_v7_defconfig), in which
some of the regulators are compiled as modules and are not available
from early boot. In such case it may happen that LDO10 is turned off by
regulator core, because it has no consumers yet (in this case consumer
drivers cannot get it, because the supply regulators for it are not yet
available). This in turn causes the board to crash. This patch restores
'always-on' property for the LDO10 regulator.

Commit
a90118c445cc ("x86/boot: Save fields explicitly, zero out everything else")
now zeroes the secure boot setting information (enabled/disabled/...)
passed by the boot loader or by the kernel's EFI handover mechanism.
The problem manifests itself with signed kernels using the EFI handoff
protocol with grub and the kernel loses the information whether secure
boot is enabled in the firmware, i.e., the log message "Secure boot
enabled" becomes "Secure boot could not be determined".
efi_main() arch/x86/boot/compressed/eboot.c sets this field early but it
is subsequently zeroed by the above referenced commit.
Include boot_params.secure_boot in the preserve field list.

Provide a Kconfig choice to select whether only the default ABI, only
call0 ABI or both are supported. The default for XEA2 is windowed, but
it may change for XEA3. Call0 only runs userspace with PS.WOE disabled.
Supporting both windowed and call0 ABIs is tricky, as there's no
indication in the ELF binaries which ABI they use. So it is done by
probing: each process is started with PS.WOE disabled, but the handler
of an illegal instruction exception taken with PS.WOE retries faulting
instruction after enabling PS.WOE. It must happen before any signal is
delivered to the process, otherwise it may be delivered incorrectly.

Pull x86 fixes from Thomas Gleixner:
"A set of fixes for x86:
- Fix the bogus detection of 32bit user mode for uretprobes which
caused corruption of the user return address resulting in
application crashes. In the uprobes handler in_ia32_syscall() is
obviously always returning false on a 64bit kernel. Use
user_64bit_mode() instead which works correctly.
- Prevent large page splitting when ftrace flips RW/RO on the kernel
text which caused iTLB performance issues. Ftrace wants to be
converted to text_poke() which avoids the problem, but for now
allow large page preservation in the static protections check when
the change request spawns a full large page.
- Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC
is configured via device tree. In the device tree case the GSI 1:1
mapping is meaningless therefore the lower bound which protects the
GSI range on ACPI machines is irrelevant. Return the lower bound
which the core hands to the function instead of blindly returning 0
which causes the core to allocate the invalid virtual interupt
number 0 which in turn prevents all drivers from allocating and
requesting an interrupt.
- Remove the bogus initialization of LDR and DFR in the 32bit bigsmp
APIC driver. That uses physical destination mode where LDR/DFR are
ignored, but the initialization and the missing clear of LDR caused
the APIC to be left in a inconsistent state on kexec/reboot.
- Clear LDR when clearing the APIC registers so the APIC is in a well
defined state.
- Initialize variables proper in the find_trampoline_placement()
code.
- Silence GCC( build warning for the real mode part of the build"

functions
Call to 'pci_free_irq_vectors()' are missing both in the error handling
path of the probe function, and in the remove function.
Add them.

This change enables the use of SW timestamping on the Raspberry Pi 4.
bcmgenet's transmit function bcmgenet_xmit() implements software
timestamping. However the SOF_TIMESTAMPING_TX_SOFTWARE capability was
missing and only SOF_TIMESTAMPING_RX_SOFTWARE was announced. By using
ethtool_ops bcmgenet_ethtool_ops() as get_ts_info(), the
SOF_TIMESTAMPING_TX_SOFTWARE capability is announced.

the following tdc test fails on Fedora:
# ./tdc.py -e 2638
-- ns/SubPlugin.__init__
Test 2638: Add matchall and try to get it
-----> prepare stage *** Could not execute: "$TC qdisc add dev $DEV1 clsact"
-----> prepare stage *** Error message: "/bin/sh: ip: command not found"
returncode 127; expected [0]
-----> prepare stage *** Aborting test run.
Let nsPlugin.py use the 'IP' variable introduced with commit 92c1a19e2fb9
("tc-tests: added path to ip command in tdc"), so that the path to 'ip' is
correctly resolved to the value we have in tdc_config.py.

QCOM_A53PLL and QCOM_CLK_APCS_MSM8916 used to be enabled by default in
drivers/clk/qcom/Kconfig. A recent patch changed that by dropping the
'default ARCH_QCOM' directive.
Add the two options explicitly in the arm64 defconfig, to avoid
functional regressions.

On embedded environments with hard memory limits it is a normal although
rare case when skb can't be allocated on rx part under high traffic.
In such OOM cases napi_complete_done() was not called.
So the napi object became in an invalid state like it is "scheduled".
Kernel do not re-schedules the poll of that napi object.
Consequently, kernel can not remove that object the system hangs on
`ifconfig down` waiting for a poll.
We are fixing this by gracefully closing napi poll routine with correct
invocation of napi_complete_done.
This was reproduced with artificially failing the allocation of skb to
simulate an "out of memory" error case and check that traffic does
not get stuck.
