81644d0b86 x86: enable Intel MID serial for Denverton SoCs
Enable CONFIG_SERIAL_8250_MID in the generic x86 configuration.

This enables hardware serial console access on Intel Atom C3000
(Denverton) platforms, which rely on the High-Speed UART driver.
It also benefits other Intel MID platforms across the x86
architecture.

d32d9ec726 x86/64: 6.12: 6.18: enable performance related options
Enable Turbo Boost Max 3.0 (INTEL_TURBO_MAX_3) to allow the kernel
scheduler to utilize preferred cores on modern Intel CPUs. This has
no effect on AMD systems.

Enable core scheduling (SCHED_CORE) to provide safer SMT task
placement and better isolation. While it can reduce peak throughput
slightly, it improves scheduling correctness on heterogeneous cores
and works across both Intel and AMD.

Enable the accelerated GHASH implementation using the CLMUL instruction
(CRYPTO_GHASH_CLMUL_NI_INTEL). This provides substantial performance
improvements for AES-GCM workloads (e.g. TLS, IPsec, OpenVPN) on CPUs
with the pclmulqdq instruction. Supported on both modern Intel and AMD
processors; falls back gracefully on older CPUs.

Run-tested twice, once with the 6.12 series and again with the 6.18.

Build system: x86/64

c9075798cc x86/64: 6.18: enable recent MITIGATION options
These mitigations are low-overhead, upstream-supported hardening options
that only activate on CPUs affected by their respective vulnerabilities.
Enabling them provides consistent, defense-in-depth coverage across Intel
and AMD systems without impacting unaffected hardware.

Detailed list:
- CONFIG_MITIGATION_SRSO to guard against known a vulnerability found on
  AMD processors (Zen generations 1-4) for sure, maybe others. This is
  tracked under CVE-2023-20569.
- CONFIG_MITIGATION_ITS to guard against a bug in BPU on some Intel CPUs
  that may allow Spectre V2 style attacks. We never enabled this option
  (and its dependencies).
- CONFIG_MITIGATION_SRBDS to guard against Special Register Buffer Data
  Sampling on affected Intel CPUs (CVE-2020-0543), preventing cross-core
  leakage of RDRAND/RDSEED/EGETKEY values.
- CONFIG_MITIGATION_SLS to guard against Spectre-v4 gadgets on x86 by
  inserting speculation barriers around RET/JMP/CALL sites when required
  by CPU/microcode state.
- CONFIG_MITIGATION_CALL_DEPTH_TRACKING to guard against speculative
  call-stack underflow on x86 by enabling hardware-assisted depth
  tracking where supported, reducing exposure to RET-based misprediction
  attacks.
- CONFIG_MITIGATION_UNRET_ENTRY to guard against RET-based speculation
  attacks on x86 by replacing vulnerable function returns in kernel
  entry paths with UNRET sequences when required by CPU/microcode state.

cddda1d44d x86: enable console keyboard
The kernel support necessary to use a console keyboard was not built on
x86, affecting real and virtual machines alike. The console keyboard
would function properly in GRUB, but would not work at all once Linux
booted. It appeared that the console was intended to work because
console video appeared on the display, including prompts to enter
failsafe or select the debug log level from the keyboard, and the prompt
to "Press Enter to activate this console", but there was no way to
provide input to it. All keystrokes were ignored.

This enables several kernel configuration options to enable HID and USB
HID support (CONFIG_HID, CONFIG_HID_SUPPORT, CONFIG_HID_GENERIC, and
CONFIG_USB_HID), making the keyboard functional. For alignment with
armsr, CONFIG_USB_HIDDEV is also added, although not strictly necessary
for keyboard support. Note that this change also causes
CONFIG_HID_HYPERV_MOUSE to be enabled for x86/64 and x86/generic: it was
already set in these subarchitectures' kernel configurations, but was
ineffective due to CONFIG_HID being absent.

The omission of keyboard support on x86 may not have been widely noticed
because USB HID is not used on production OpenWrt x86 machines such as
pc-engines,apu2 which only have a serial console, or with the default
x86 configuration used by scripts/qemustart, which uses -nographic and
does not configure a virtual physical console but instead uses a serial
console.

This configuration change results in, for x86_64, +40kB in kernel.bin
and just over +40kB in gzip-compressed "combined" images. This should
not be a problem for the non-storage-constrained x86 target.

Until 2a86425de107, CONFIG_HID, CONFIG_USB_HID, and CONFIG_USB_HIDDEV
were set in the target-level kernel configuration, and
CONFIG_HID_GENERIC was set at the subtarget level. These are
reintroduced strictly at the subtarget level by request. This applies to
the 64, generic, and legacy subtargets, omitting geode.

34615250a9 x86/64: enable Intel PINCTRL in 64bit target
Intel PINCTRL is not enable in the 64bit build, while it is enabled in
the x86/general target, which disables the ability of controlling GPIO
in the 64 bit build.

This commit copies the corresponding part of x86/general config, since
it is already there, so it should be fine to enable the same settings
here.

f08f7e88c9 kernel: Move some IOMMU options to generic
This adds some missing IOMMU related options for x86/64 and moves some
of them to generic for all targets.

On x86 IOMMU_DEFAULT_DMA_LAZY is used by default, on all other platforms
IOMMU_DEFAULT_DMA_STRICT is the default. we just follow the default
kernel configuration here.

8fea4a102c x86/64: enable IOMMU support
Enable IOMMU support for Intel and AMD x86 platforms. With this, when the
vfio module is present, physical PCI devices can be passed to VMs, for
example with `qemu-system-x86_64 -device vfio-pci,host=05:00.0 ...`.

IOMMU support increases the kernel size by a small amount (~370KB, from
5239840 B to 5611200 B, a ~7% increase in size).
