We have Beaglebone Black based custom board, with Linux 4.4.
I wanted to track down the low level function corresponding to the reboot() system call.
I am able to see sys_reboot() in include/uapi/asm-generic/unistd.h however I am not able to get to definition of the sys_reboot function.
Where can I find the definition of sys_reboot in the kernel source?

The reboot system call is defined in kernel/reboot.c — look for SYSCALL_DEFINE4(reboot.
For ARM systems you’ll probably be interested in the ARM-specific support in arch/arm/kernel/reboot.c, and perhaps in machine-specific support in one of the arch/arm/mach-… directories.
