    Subject[PATCH 5.18 290/339] scripts/gdb: change kernel config dumping method
    Date
    From: Kuan-Ying Lee <Kuan-Ying.Lee@mediatek.com>

    [ Upstream commit 1f7a6cf6b07c74a17343c2559cd5f5018a245961 ]

    MAGIC_START("IKCFG_ST") and MAGIC_END("IKCFG_ED") are moved out
    from the kernel_config_data variable.

    Thus, we parse kernel_config_data directly instead of considering
    offset of MAGIC_START and MAGIC_END.

    Fixes: 13610aa908dc ("kernel/configs: use .incbin directive to embed config_data.gz")
