Pull Kbuild updates from Masahiro Yamada:

 - Add -s option (strict mode) to merge_config.sh to make it fail when
   any symbol is redefined.

 - Show a warning if a different compiler is used for building external
   modules.

 - Infer --target from ARCH for CC=clang to let you cross-compile the
   kernel without CROSS_COMPILE.

 - Make the integrated assembler default (LLVM_IAS=1) for CC=clang.

 - Add <linux/stdarg.h> to the kernel source instead of borrowing
   <stdarg.h> from the compiler.

 - Add Nick Desaulniers as a Kbuild reviewer.

 - Drop stale cc-option tests.

 - Fix the combination of CONFIG_TRIM_UNUSED_KSYMS and CONFIG_LTO_CLANG
   to handle symbols in inline assembly.

 - Show a warning if 'FORCE' is missing for if_changed rules.

 - Various cleanups

  Enhancements:

   - A major refactoring of the Rockchip driver, breaking part of it out
     to a separate GPIO driver in drivers/gpio

   - Pin bias support on Renesas r8a77995

   - Add SCI pins support to Ingenic JZ4755 and JZ4760

Pull irq updates from Thomas Gleixner:
 "Updates to the interrupt core and driver subsystems:

  Core changes:

   - The usual set of small fixes and improvements all over the place,
     but nothing stands out

  MSI changes:

   - Further consolidation of the PCI/MSI interrupt chip code

   - Make MSI sysfs code independent of PCI/MSI and expose the MSI
     interrupts of platform devices in the same way as PCI exposes them.

  Driver changes:

   - Support for ARM GICv3 EPPI partitions

   - Treewide conversion to generic_handle_domain_irq() for all chained
     interrupt controllers

   - Conversion to bitmap_zalloc() throughout the irq chip drivers

   - The usual set of small fixes and improvements"

Delete/fixup few includes in anticipation of global -isystem compile
option removal.

Note: crypto/aegis128-neon-inner.c keeps <stddef.h> due to redefinition
of uintptr_t error (one definition comes from <stddef.h>, another from
<linux/types.h>).

Samsung pinctrl drivers changes for v5.15

1. Fix number of pins in one GPIO pin bank.
2. Add support for Exynos850 SoC (Exynos3830).

With the patch to separate the gpio driver from the pinctrl driver, now
the pinctrl-rockchip can drop the gpio related codes now.
