Improvements: - Shell now starts successfully without segfaults. --- build/kernel.elf | Bin 296040 -> 296848 bytes build/src/kernel/initcode.o | Bin 31496 -> 31528 bytes build/src/kernel/mm/vm.o | Bin 234008 -> 234008 bytes build/src/kernel/proc/exec.o | Bin 62896 -> 64304 bytes build/src/kernel/proc/proc.o | Bin 221432 -> 225240 bytes build/src/kernel/trap/handler.o | Bin 71232 -> 72624 bytes build/ulib/stdlib.o | Bin 170728 -> 170968 bytes build/user/initcode | Bin 30472 -> 30504 bytes build/user/initcode.asm | 2532 +++---- build/user/initcode.out | Bin 168736 -> 168776 bytes build/user/sh | Bin 204136 -> 204528 bytes build/user/sh.asm | 14618 +++++++++++++++++++------------------- build/user/sh.o | Bin 285040 -> 287784 bytes fs.img | Bin 33554432 -> 33554432 bytes include/kernel/proc_def.h | 4 + include/kernel/riscv.h | 3 +- src/kernel/mm/vm.cc | 3 -
