parisc: Use long branch to do_syscall_trace_exit
Browse files Browse the repository at this point in the history
Use the 22bit instead of the 17bit branch instruction on a 64bit kernel
to reach the do_syscall_trace_exit function from the gateway page.
A huge page enabled kernel may need the additional branch distance bits.
