Until now the hpp and sort functions do similar jobs different ways.
Since the sort functions converted/wrapped to hpp formats it can do

Does perf support different length of user-space hw_breakpoint,
such as HW_BREAKPOINT_LEN_1/HW_BREAKPOINT_LEN_2/HW_BREAKPOINT_LEN_4/
HW_BREAKPOINT_LEN_8?
Seems perf only support HW_BREAKPOINT_LEN_4/sizeof(long)
by default from the source code and simple test.
May I have your opinions

We are going to extend irq work to support remote queuing.
So lets add a cpu argument to arch_irq_work_raise(). The architectures
willing to support that must then provide the backend to raise irq work
