Don't bother restoring r28 on syscall restarts; it's clobbered by syscall anyway. Reuse (now unused) ->orig_r28 as "no restarts allowed" flag. Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

1) Gate immediately and save a branch. 2) Fix off by one error in checking entry number. 3) Use sr7 instead of sr3 in error return path as sr3 might not contain correct value. 4) Enable locking on UP systems to prevent incorrect operation of the cas_action critical region on page faults. Tested on several systems, including UP c3750 with 2.6.33.2 kernel. Signed-off-by: NJohn David Anglin <dave.anglin@nrc-cnrc.gc.ca> Signed-off-by: NKyle McMartin <kyle@parisc-linux.org>

Instead of fiddling with gr[20], restructure code to return whether or not to -ENOSYS. (Also do a bit of fiddling to let them take pt_regs directly instead of re-computing it.) Signed-off-by: NKyle McMartin <kyle@mcmartin.ca>

This makes parisc use the standard tracehook_report_syscall_entry and tracehook_report_syscall_exit hooks in <linux/tracehook.h>. To do this, we need to access current->thread.regs, and to know whether we're entering or exiting the syscall, so add this to syscall_trace. Signed-off-by: NKyle McMartin <kyle@mcmartin.ca>

The bug was that we were comparing __NR_syscalls to be greater or equal to the syscall number stored in %r20. __NR_syscalls is one greater than the last syscall though, so we're loading one entry beyond the end of the syscall table, and trying to jump to it. Fix this by only checking that we're greater, alternatively, we could have compared to (__NR_Linux_syscalls - 1) Signed-off-by: NKyle McMartin <kyle@parisc-linux.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
