Use the secondary_exec_controls_get() accessor in vmx_has_waitpkg() to
effectively get the controls for the current VMCS, as opposed to using
vmx->secondary_exec_controls, which is the cached value of KVM's desired
controls for vmcs01 and truly not reflective of any particular VMCS.
While the waitpkg control is not dynamic, i.e. vmcs01 will always hold
the same waitpkg configuration as vmx->secondary_exec_controls, the same
does not hold true for vmcs02 if the L1 VMM hides the feature from L2.
If L1 hides the feature _and_ does not intercept MSR_IA32_UMWAIT_CONTROL,
L2 could incorrectly read/write L1's virtual MSR instead of taking a #GP.

Remove an ancient restriction that disallowed exposing EFER.NX to the
guest if EFER.NX=0 on the host, even if NX is fully supported by the CPU.
The motivation of the check, added by commit 2cc51560aed0 ("KVM: VMX:
Avoid saving and restoring msr_efer on lightweight vmexit"), was to rule
out the case of host.EFER.NX=0 and guest.EFER.NX=1 so that KVM could run
the guest with the host's EFER.NX and thus avoid context switching EFER
if the only divergence was the NX bit.
Fast forward to today, and KVM has long since stopped running the guest
with the host's EFER.NX. Not only does KVM context switch EFER if
host.EFER.NX=1 && guest.EFER.NX=0, KVM also forces host.EFER.NX=0 &&
guest.EFER.NX=1 when using shadow paging (to emulate SMEP). Furthermore,
the entire motivation for the restriction was made obsolete over a decade
ago when Intel added dedicated host and guest EFER fields in the VMCS
(Nehalem timeframe), which reduced the overhead of context switching EFER
from 400+ cycles (2 * WRMSR + 1 * RDMSR) to a mere ~2 cycles.
In practice, the removed restriction only affects non-PAE 32-bit kernels,
as EFER.NX is set during boot if NX is supported and the kernel will use
PAE paging (32-bit or 64-bit), regardless of whether or not the kernel
will actually use NX itself (mark PTEs non-executable).
Alternatively and/or complementarily, startup_32_smp() in head_32.S could
be modified to set EFER.NX=1 regardless of paging mode, thus eliminating
the scenario where NX is supported but not enabled. However, that runs
the risk of breaking non-KVM non-PAE kernels (though the risk is very,
very low as there are no known EFER.NX errata), and also eliminates an
easy-to-use mechanism for stressing KVM's handling of guest vs. host EFER
across nested virtualization transitions.

The current comment states that we check if the 64-bit kernel mapping
overlaps with the last 4K of the address space that is reserved to
error values in create_kernel_page_table, which is not the case since it
is done in setup_vm. But anyway, remove the reference to any function
and simply note that in 64-bit kernel, the check should be done as soon
as the kernel mapping base address is known.

FPU_STATUS register contains FP exception flags bits which are updated
by core as side-effect of FP instructions but can also be manually
wiggled such as by glibc C99 functions fe{raise,clear,test}except() etc.
To effect the update, the programming model requires OR'ing FWE
bit (31). This bit is write-only and RAZ, meaning it is effectively
auto-cleared after write and thus needs to be set everytime: which
is how glibc implements this.
However there's another usecase of FPU_STATUS update, at the time of
Linux task switch when incoming task value needs to be programmed into
the register. This was added as part of f45ba2bd6da0dc ("ARCv2:
fpu: preserve userspace fpu state") which missed OR'ing FWE bit,
meaning the new value is effectively not being written at all.
This patch remedies that.
Interestingly, this snafu was not caught in interm glibc testing as the
race window which relies on a specific exception bit to be set/clear is
really small specially when it nvolves context switch.
Fortunately this was caught by glibc's math/test-fenv-tls test which
repeatedly set/clear exception flags in a big loop, concurrently in main
program and also in a thread.

- Both runs on small cores.
- They have different adaptive PEBS configuration (PEBS_DATA_CFG).

Different from the big core, the small core requires the ACK right
before re-enabling counters in the NMI handler, otherwise a stale PEBS
record may be dumped into the later NMI handler, which trigger the
warning.
Add a new mid_ack flag to track the case. Add all PMI handler bits in
the struct x86_hybrid_pmu to track the bits for different types of
PMUs. Apply mid ACK for the small cores on an Alder Lake machine.
The existing hybrid() macro has a compile error when taking address of
a bit-field variable. Add a new macro hybrid_bit() to get the
bit-field value of a given PMU.

The problem being that it doesn't filter out all fake counters, in
specific the above (erroneously) tries to use FIXED_BTS. Limit the
fixed counters indexes to the hardware supplied number.

Correct big-endian accesses to the CBUS UART, a Malta on-board discrete
TI16C550C part wired directly to the system controller's device bus, and
do not use byte swapping with the 32-bit accesses to the device.
The CBUS is used for devices such as the boot flash memory needed early
on in system bootstrap even before PCI has been initialised. Therefore
it uses the system controller's device bus, which follows the endianness
set with the CPU, which means no byte-swapping is ever required for data
accesses to CBUS, unlike with PCI.
The CBUS UART uses the UPIO_MEM32 access method, that is the `readl' and
`writel' MMIO accessors, which on the MIPS platform imply byte-swapping
with PCI systems. Consequently the wrong byte lane is accessed with the
big-endian configuration and the UART is not correctly accessed.
As it happens the UPIO_MEM32BE access method makes use of the `ioread32'
and `iowrite32' MMIO accessors, which still use `readl' and `writel'
respectively, however they byte-swap data passed, effectively cancelling
swapping done with the accessors themselves and making it suitable for
the CBUS UART.
Make the CBUS UART switch between UPIO_MEM32 and UPIO_MEM32BE then,
based on the endianness selected. With this change in place the device
is correctly recognised with big-endian Malta at boot, along with the
Super I/O devices behind PCI:

The removal of this config exposes CONFIG_PHYS_RAM_BASE for all kernel
types: this value being implementation-specific, this breaks the
genericity of the RISC-V kernel so revert it.

The usage of CONFIG_PHYS_RAM_BASE for all kernel types was a mistake:
this value is implementation-specific and this breaks the genericity of
the RISC-V kernel.
Fix this by introducing a new variable phys_ram_base that holds this
value at runtime and use it in the kernel physical address conversion
macro. Since this value is used only for XIP kernels, evaluate it only if
CONFIG_XIP_KERNEL is set which in addition optimizes this macro for
standard kernels at compile-time.

riscv uses the value of TSK_STACK_CANARY to set
stack-protector-guard-offset. With GCC_PLUGIN_RANDSTRUCT enabled, that
value is non-deterministic, and with riscv:allmodconfig often results
in build errors such as
cc1: error: '8120' is not a valid offset in '-mstack-protector-guard-offset='
Enable STACKPROTECTOR_PER_TASK only if GCC_PLUGIN_RANDSTRUCT is disabled
to fix the problem.

The reason is the task is NULL when we finally call walk_stackframe()
the NULL is passed from __dump_stack():
|static void __dump_stack(void)
|{
| dump_stack_print_info(KERN_DEFAULT);
| show_stack(NULL, NULL, KERN_DEFAULT);
|}
Fix this issue by checking "task == NULL" case in walk_stackframe().

This device tree include file describes a fixed-regulator
connecting smps7_reg output (1.8V) to some 1.8V rail and
consumers (vdds_1v8_main).
This regulator does not physically exist.
I assume it was introduced as a wrapper around smps7_reg
to provide a speaking signal name "vdds_1v8_main" as label.
This fixed-regulator without real function was not an issue
in driver code until
Commit 98e48cd9283d ("regulator: core: resolve supply for boot-on/always-on regulators")
introduced a new check for regulator initialization which
makes Palmas regulator registration fail:
[ 5.407712] ldo1: supplied by vsys_cobra
[ 5.412748] ldo2: supplied by vsys_cobra
[ 5.417603] palmas-pmic 48070000.i2c:palmas@48:palmas_pmic: failed to register 48070000.i2c:palmas@48:palmas_pmic regulator
The reason is that the supply-chain of regulators is too
long and goes from ldo3 through the virtual vdds_1v8_main
regulator and then back to smps7. This adds a cross-dependency
of probing Palmas regulators and the fixed-regulator which
leads to probe deferral by the new check and is no longer
resolved.
Since we do not control what device tree files including this
one reference (either &vdds_1v8_main or &smps7_reg or both)
we keep both labels for smps7 for compatibility.

Based on the latest timing specifications for the TPS65218 from the data
sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206
from November 2014, we must change the i2c bus speed to better fit within
the minimum high SCL time required for proper i2c transfer.
When running at 400khz, measurements show that SCL spends
0.8125 uS/1.666 uS high/low which violates the requirement for minimum
high period of SCL provided in datasheet Table 7.6 which is 1 uS.
Switching to 100khz gives us 5 uS/5 uS high/low which both fall above
the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low.
Without this patch occasionally a voltage set operation from the kernel
will appear to have worked but the actual voltage reflected on the PMIC
will not have updated, causing problems especially with cpufreq that may
update to a higher OPP without actually raising the voltage on DCDC2,
leading to a hang.

Some SFP modules are not detected when i2c-fast-mode is enabled even when
clock-frequency is already set to 100000. The I2C bus violates the timing
specifications when run in fast mode. So disable fast mode on Turris Mox.
Same change was already applied for uDPU (also Armada 3720 board with SFP)
in commit fe3ec631a77d ("arm64: dts: uDPU: remove i2c-fast-mode").

Since drivers/mmc/host/sdhci-xenon.c declares the PROBE_PREFER_ASYNCHRONOUS
probe type, it is not guaranteed whether /dev/mmcblk0 will belong to
sdhci0 or sdhci1. In turn, this will break booting by:
root=/dev/mmcblk0p1
Fix the issue by adding aliases so that the old MMC controller indices
are preserved.

While 7e5f3155dcbb4 ("ARM: dts: stm32: Fix LED5 on STM32MP1 DHCOM PDK2")
fixed the LED0 assignment on the PDK2 board, the same commit did not
update the touchscreen IRQ line assignment, which is the same GPIO line,
shared between the LED0 output and touchscreen IRQ input. To make this
more convoluted, the same EXTI input (not the same GPIO line) is shared
between Button B which is Active-Low IRQ, and touchscreen IRQ which is
Edge-Falling IRQ, which cannot be used at the same time. In case the LCD
board with touchscreen is in use, which is the case here, LED0 must be
disabled, Button B must be polled, so the touchscreen interrupt works as
it should.
Update the touchscreen IRQ line assignment, disable LED0 and use polled
GPIO button driver for Button B, since the DT here describes baseboard
with LCD board.

The LAN8710 Energy Detect Power Down (EDPD) functionality might cause
unreliable cable detection. There are multiple accounts of this in the
SMSC PHY driver patches which attempted to make EDPD reliable, however
it seems there is always some sort of corner case left. Unfortunatelly,
there is no errata documented which would confirm this to be a silicon
bug on the LAN87xx series of PHYs (LAN8700, LAN8710, LAN8720 at least).
Disable EDPD on the DHCOM SoM, just like multiple other boards already
do as well, to make the cable detection reliable.

The DHCOM SoM has two RTC, one is the STM32 RTC built into the SoC
and another is Microcrystal RV RTC. By default, only the later has
battery backup, the former does not. The order in which the RTCs
are probed on boot is random, which means the kernel might pick up
system time from the STM32 RTC which has no battery backup. This
then leads to incorrect initial system time setup, even though the
HW RTC has correct time configured in it.
Add DT alias entries, so that the RTCs get assigned fixed IDs and
the HW RTC is always picked by the kernel as the default RTC, thus
resulting in correct system time in early userspace.

The pinctrl_power_button/pinctrl_power_out each define single GPIO
pinmux, except it is exactly the other one than the matching gpio-keys
and gpio-poweroff DT nodes use for that functionality. Swap the two
GPIOs to correct this error.

The function imx_mmdc_perf_init recently had a 3rd argument added to
it but the equivalent macro was not updated and is still the older
2 argument version. Fix this by adding in the missing 3rd argumement
mmdc_ipg_clk.

NXP and AzureWave don't recommend using SDIO bus mode 3.3V@50MHz due
to noise affecting the wireless throughput. Colibri iMX6ULL uses only
3.3V signaling for Wi-Fi module AW-CM276NF.
Limit the SDIO Clock on Colibri iMX6ULL to 25MHz.

The PHY configuration for the variant 2 is still missing the flag for
in-band signalling between PHY and MAC. Both sides - MAC and PHY - have
to match the setting. For now, Linux only supports setting the MAC side
and thus it has to match the setting the bootloader is configuring.
Enable in-band signalling to make ethernet work.

The AR803x PHY used on this modules seems to require the reset line to
be asserted for around 10ms in order to avoid rare cases where the PHY
gets stuck in an incoherent state that prevents it to function
correctly.
The previous value of 2ms was found to be problematic on some setups,
causing intermittent issues where the PHY would be unresponsive
every once in a while on some sytems, with a low occurrence (it typically
took around 30 consecutive reboots to encounter the issue).
Bumping the delay to the 10ms makes the issue dissapear, with more than
2500 consecutive reboots performed without the issue showing-up.
