代码审查意见如下：

1. 在arch/arm64/configs/deepin_arm64_desktop_defconfig文件中，移除了CONFIG_PCI_IOV配置项，但未提供移除的原因。如果该配置项不再需要，请确认是否有替代方案或相关文档说明。如果移除是必要的，请确保没有其他模块依赖于该配置项。

2. 在arch/arm64/configs/deepin_arm64_desktop_defconfig文件中，添加了CONFIG_BRCMSTB_GISB_ARB=m等新的配置项。请确保这些配置项是必要的，并且已经过充分测试。如果这些配置项是新增功能的一部分，请提供相应的文档或测试结果。

3. 在arch/arm64/configs/deepin_arm64_desktop_defconfig文件中，移除了CONFIG_CRYPTO_DES=m和CONFIG_CRYPTO_CHACHA20POLY1305=m配置项。如果这些配置项不再需要，请确认是否有替代方案或相关文档说明。如果移除是必要的，请确保没有其他模块依赖于这些配置项。

4. 在arch/loongarch/configs/deepin_loongarch_desktop_defconfig文件中，添加了CONFIG_CMDLINE="vfio_iommu_type1.allow_unsafe_interrupts=1 nokaslr"和CONFIG_CMDLINE_EXTEND=y配置项。请确保这些配置项是必要的，并且已经过充分测试。如果这些配置项是新增功能的一部分，请提供相应的文档或测试结果。

5. 在arch/loongarch/configs/deepin_loongarch_desktop_defconfig文件中，移除了CONFIG_KPROBES配置项。如果该配置项不再需要，请确认是否有替代方案或相关文档说明。如果移除是必要的，请确保没有其他模块依赖于该配置项。

6. 在arch/loongarch/configs/deepin_loongarch_desktop_defconfig文件中，添加了CONFIG_VFIO_PCI_INTX=y和CONFIG_QAT_VFIO_PCI=m配置项。请确保这些配置项是必要的，并且已经过充分测试。如果这些配置项是新增功能的一部分，请提供相应的文档或测试结果。

7. 在arch/x86/configs/deepin_x86_desktop_defconfig文件中，添加了CONFIG_VGA_SWITCHEROO=y和CONFIG_DRM_DEBUG_DP_MST_TOPOLOGY_REFS=y配置项。请确保这些配置项是必要的，并且已经过充分测试。如果这些配置项是新增功能的一部分，请提供相应的文档或测试结果。

8. 在arch/x86/configs/deepin_x86_desktop_defconfig文件中，移除了CONFIG_RUNTIME_TESTING_MENU配置项。如果该配置项不再需要，请确认是否有替代方案或相关文档说明。如果移除是必要的，请确保没有其他模块依赖于该配置项。

• Removing PCI_IOV support disables SR-IOV functionality, which may be required for virtualization workloads; verify if this was intentional or revert it.

CONFIG_PCI_IOV=y

arch/arm64/configs/deepin_arm64_desktop_defconfig:4484

• Removing the CHACHA20-POLY1305 cipher may break kernel modules or userland features that depend on it; ensure there’s an alternative or re-enable support.

CONFIG_CRYPTO_CHACHA20POLY1305=m

arch/x86/configs/deepin_x86_desktop_defconfig:3361

• [nitpick] Enabling a debug flag in the default config may degrade runtime performance; consider disabling this in production defconfigs or gating it behind a debug build option.

CONFIG_DRM_DEBUG_DP_MST_TOPOLOGY_REFS=y

arch/x86/configs/deepin_x86_desktop_defconfig:3382

• [nitpick] Treating warnings as errors for the i915 driver can break builds if kernel warnings appear; consider removing or making this optional to avoid unexpected CI failures.

CONFIG_DRM_I915_WERROR=y

arch/loongarch/configs/deepin_loongarch_desktop_defconfig:60

• Disabling KASLR and allowing unsafe interrupts weakens kernel security; recommend removing or documenting the risk for production builds.

CONFIG_CMDLINE="vfio_iommu_type1.allow_unsafe_interrupts=1 nokaslr"
