Jisheng Zhang e01e9ae43e riscv: define ILLEGAL_POINTER_VALUE for 64bit ... commit 5c178472af247c7b50f962495bb7462ba453b9fb upstream. This is used in poison.h for poison pointer offset. Based on current SV39, SV48 and SV57 vm layout, 0xdead000000000000 is a proper value that is not mappable, this can avoid potentially turning an oops to an expolit.
