345a61fa7c Removed the redundant mem_write_null* functions (the few mappings that use them, now use NULL pointers instead) and made the _phys function used by DMA not write to the exec buffer if the address has no write mapping (as in that case, it's clearly not intended to be writable), fixes #1332. 2021-03-30 02:16:01 +02:00
