HAOC: CREDP: Fix build error when CREDP is off

[amjac27]

CRED_DATA is not defined in vmlinux.lds.S when CREDP is not defined, which could lead to build error. Fix this problem both in X86 and ARM64.

Summary by Sourcery

Bug Fixes:

• Prevent undefined CRED_DATA in vmlinux.lds.S by providing an empty definition when CONFIG_CREDP is off

Reviewer's Guide

Introduce a fallback definition for CRED_DATA in the kernel linker scripts for both ARM64 and x86 when CREDP is disabled to prevent build errors.

Hi @amjac27. Thanks for your PR.

I'm waiting for a deepin-community member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Hey @amjac27 - I've reviewed your changes - here's some feedback:

• Consider consolidating the empty CRED_DATA stub into a shared header or macro to avoid duplicating the same #define across ARM64 and x86 vmlinux.lds.S files.
• Make sure to apply the same empty CRED_DATA definition to any other architectures (e.g. MIPS, PowerPC) that include vmlinux.lds.S to prevent similar build failures when CONFIG_CREDP is off.

Here's what I looked at during the review

• 🟢 General issues: all looks good
• 🟢 Testing: all looks good
• 🟢 Complexity: all looks good
• 🟢 Documentation: all looks good
