James Hogan 8595d11eb4 target/mips: Check memory permissions with mem_idx ... When performing virtual to physical address translation, check the required privilege level based on the mem_idx rather than the mode in the hflags. This will allow EVA loads & stores to operate safely only on user memory from kernel mode. For the cases where the mmu_idx doesn't need to be overridden (mips_cpu_get_phys_page_debug() and cpu_mips_translate_address()), we calculate the required mmu_idx using cpu_mmu_index(). Note that this only tests the MIPS_HFLAG_KSU bits rather than MIPS_HFLAG_MODE, so we don't test the debug mode hflag MIPS_HFLAG_DM any longer. This should be fine as get_physical_address() only compares against MIPS_HFLAG_UM and MIPS_HFLAG_SM, neither of which should get set by compute_hflags() when MIPS_HFLAG_DM is set.
