I am updating the mdb kernel debugger on 4.2.4 and I noticed that
user_mode_vm has been removed from the kernel sources for detecting
user space memory addresses for purposes of loading the SS pointer. I
am using __KERNEL_DS presently.
old code:
if (user_mode_vm(regs))
{
sf->tSS = regs->ss;
sf->tSP = regs->sp;
} else {
sf->tSS = __KERNEL_DS;
sf->tSP = kernel_stack_pointer(regs);
}
is SS always assumed to be __KERNEL_DS in 4.2.4 for userspace stack
addresses passed by pt_regs?
Thanks
Jeff
