- wfi(ARM) instruction doesn't work correctly and not to
- use it. This is also useful when using JTAG debugger.
+ nohlt [ARM,ARM64,MICROBLAZE,SH] Forces the kernel to busy wait
+ in do_idle() and not use the arch_cpu_idle()
+ implementation; requires CONFIG_GENERIC_IDLE_POLL_SETUP

+ that hides actual kernel addresses from unprivileged
+ users, but it also makes debugging the kernel more
+ difficult since unequal pointers can no longer be
+ compared. However, if this command-line option is
+ specified, then all normal pointers will have their true
+ value printed. Pointers printed via %pK may still be
+ hashed. This option should only be specified when
+ debugging the kernel. Please do not use on production
+ kernels.
