ARM64 CPUidle driver requires the cpu_do_idle function so that it can be used to enter the shallowest idle state, and it is declared in asm/proc-fns.h. The current ARM64 CPUidle driver does not include asm/proc-fns.h explicitly and it has so far relied on implicit inclusion from other header files. Owing to some header dependencies reshuffling this currently triggers build failures when CONFIG_ARM64_64K_PAGES=y: drivers/cpuidle/cpuidle-arm64.c: In function "arm64_enter_idle_state" drivers/cpuidle/cpuidle-arm64.c:42:3: error: implicit declaration of function "cpu_do_idle" [-Werror=implicit-function-declaration] cpu_do_idle(); ^ This patch adds the explicit inclusion of the asm/proc-fns.h header file in the arm64 asm/cpuidle.h header file, so that the build breakage is fixed and the required header inclusion is added to the appropriate arch back-end CPUidle header, already included by the CPUidle arm64 driver, where CPUidle arch related function declarations belong.
