[PATCH OLK-6.6 0/1] arm64: ipi_nmi: fix compile error when CONFIG_KGDB is disabled
arch/arm64/kernel/ipi_nmi.c: In function ¡®ipi_nmi_handler¡¯: arch/arm64/kernel/ipi_nmi.c:54:7: error: implicit declaration of function ¡®kgdb_nmicallback¡¯ [-Werror=implicit-function-declaration] if (!kgdb_nmicallback(cpu, get_irq_regs())) ^~~~~~~~~~~~~~~~ kgbd_nmicallback is only defined when CONFIG_KGDB is set up. Use macro to warp CONFIG_KGDB to address the issue.
