Re: [PATCH v5] ARM: uprobes need icache flush after xol write

Note ARM cache flush function need kernel address through which instruction write happened, so instead of using uprobes copy_to_page function changed code to explicitly map page and do memcpy.

Again, I can't review the changes in arm/, although I think there are correct.

FWIW,
