Marcin Nowakowski 297e765e39 uprobes: Fix uprobes on MIPS, allow for a cache flush after ixol breakpoint creation ... Commit: 72e6ae285a ('ARM: 8043/1: uprobes need icache flush after xol write' ... has introduced an arch-specific method to ensure all caches are flushed appropriately after an instruction is written to an XOL page. However, when the XOL area is created and the out-of-line breakpoint instruction is copied, caches are not flushed at all and stale data may be found in icache. Replace a simple copy_to_page() with arch_uprobe_copy_ixol() to allow the arch to ensure all caches are updated accordingly. This change fixes uprobes on MIPS InterAptiv (tested on Creator Ci40).
