I don't understand. These are normal syscalls.
and (b) using -1..-4 for the syscall numbers works out quite nicely
for the code in entry.S. It adds just a couple of instructions to the
execution path.
Those additional instructions are totally unnecessary.
Hm, I though it would be preferable to keep syscalls that are specific to
m68k (in the sense that no other target requires them) separate from the
ones implementing standard unix/linux functionality.
If the consensus is that the new syscalls should received 331..334 numbers,
that would only simplify the implementation.
I prefer to just add them at the bottom of the list.
(slowly recovering from my backlog) I noticed some new syscalls got
added recently:
| <stdin>:1515:2: warning: #warning syscall rt_tgsigqueueinfo not implemented
| <stdin>:1519:2: warning: #warning syscall perf_counter_open not implemented
Probably I should wire those up first (for 2.6.31, if still possible).
Next I should reserve 333..336 for you?
That's fine, thank you. I'll follow up with an updated patch in couple
of days.
