v1 -> v2: Use /proc/self/mem as a fallback. Handle TB invalidation (Richard). Test cross-page accesses. RFC: https://lists.gnu.org/archive/html/qemu-devel/2023-12/msg02044.html RFC -> v1: Use /proc/self/mem and accept that this will not work without /proc. Factor out a couple functions for gdbstub testing. Add a test. Hi, I've noticed that gdbstub behaves differently from gdbserver in that it doesn't allow reading non-readable pages. This series improves the situation by using the same mechanism as gdbserver: /proc/self/mem.
