entry-point is either sys_nomodule or sys_nosys. Update the makesyscalls.sh script to create a const array of bits to allow syscall_disestablish() to properly restore the original entry-point. Update all the initializers of struct emul to initialize the pointer to the bit array struct emul. XXX Regen of all files created by makesyscalls.sh will come soon, XXX followed by a kernel version bump (since struct emul is being XXX modified). This commit should address PR kern/45781 and also removes the need for the work-around for that PR in file sys/arch/usermode/modules/syscallemu/syscallemu.c
