d5ea70ead8 pinctrl: renesas: r8a77951: Optimize fixed-width reserved fields 
Describe registers with fixed-width register fields and many reserved
fields using the PINMUX_CFG_REG_VAR() macro, as the latter supports a
shorthand not requiring dummy values.

This reduces kernel size by 496 bytes.

6210905586 pinctrl: renesas: Add shorthand for reserved register fields 
Currently, reserved register fields must be fully described using dummy
enum IDs (zeroes), one for each possible state (2^bits states).

Add support for describing reserved fields using negative field width
values as shorthands, thus removing the need for dummy values.  Apart
from the obvious size reduction due to the removal of the dummy values,
this will also enable merging adjacent reserved fields into a single
field, reducing the number of fields to describe, and thus kernel size.

Update the checker accordingly.

Unlike on R-Car Gen3 SoCs, setting a bit to zero in a GPIO / Peripheral
Function Select Register (GPSRn) on R-Car S4-8 is not always sufficient
to configure a pin for GPIO.  For I2C-capable pins, the I2C function
must also be explicitly disabled in the corresponding Module Select
Register (MODSELn).

Add the missing FN_SEL_I2Ci_0 function enums to the pinmux_data[] array

1db28b78b3 pinctrl: renesas: Select PINCTRL_RZG2L if ARCH_RZG2L is enabled 
GPIO (PINCTRL) block is identical on Renesas RZ/G2L, RZ/G2UL and RZ/V2L
SoC's, so instead of selecting PINCTRL_RZG2L config for each SoC select
PINCTRL_RZG2L config option if ARCH_RZG2L is enabled. The ARCH_RZG2L
config option is already selected by ARCH_R9A07G043, ARCH_R9A07G044 and
ARCH_R9A07G054.

bfc69bdbaa pinctrl: renesas: rzg2l: Add RZ/G2UL support 
RZ/G2UL SoC has fewer pins compared to RZ/G2L and the port pin
definitions are different compared to RZ/G2L.

This patch adds a new compatible to take care of these differences by
adding r9a07g043_data with r9a07g043_gpio_configs and
rzg2l_dedicated_pins.common.

dd035683fd pinctrl: renesas: checker: Rework drive and bias pin iteration 
The checker code to iterate over all drive strength and bias register
description items is cumbersome, due to the repeated calculation of
indices, and the use of hardcoded array sizes.  The latter was done
under the assumption they would never need to be changed, which turned
out to be false.

Increase readability by introducing helper macros to access drive
strength and bias register description items.
Increase maintainability by replacing hardcoded numbers by array sizes
calculated at compile-time.

Pull x86 fixes from Thomas Gleixner:
 "A set of x86 fixes and updates:

   - Make the prctl() for enabling dynamic XSTATE components correct so
     it adds the newly requested feature to the permission bitmap
     instead of overwriting it. Add a selftest which validates that.

   - Unroll string MMIO for encrypted SEV guests as the hypervisor
     cannot emulate it.

   - Handle supervisor states correctly in the FPU/XSTATE code so it
     takes the feature set of the fpstate buffer into account. The
     feature sets can differ between host and guest buffers. Guest
     buffers do not contain supervisor states. So far this was not an
     issue, but with enabling PASID it needs to be handled in the buffer
     offset calculation and in the permission bitmaps.

   - Avoid a gazillion of repeated CPUID invocations in by caching the
     values early in the FPU/XSTATE code.

   - Enable CONFIG_WERROR in x86 defconfig.

   - Make the X86 defconfigs more useful by adapting them to Y2022
     reality"
