gdbserver inserting a breakpoint ends up calling copy_user_page() for a code page. The generic version of which (non-aliasing config) didn't set the PG_arch_1 bit hence update_mmu_cache() didn't sync dcache/icache for corresponding dynamic loader code page - causing garbade to be executed. So now aliasing versions of copy_user_highpage()/clear_page() are made default. There is no significant overhead since all of special alias handling code is compiled out for non-aliasing build Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
