sys/ia64/ia64 trap.c
Log:
Now that we define user mode as any IP address that isn't in the
kernel's VA regions, we cannot limit the use of break-based
syscalls to user mode only. The signal trampolines are in the
gateway page, which is mapped into the process address space in
region 5 and thus is kernel space.
We don't special case the gateway page here. Allow break-based
syscalls from anywhere in the kernel VA space.
