fvdl 7f5724ad4c In the case of MAP_ANON, Linux mmap ignores the fd argument completely.
So, always pass -1 to the native syscall in that case, to avoid
errors if a Linux app doesn't specify -1 as the fd (which some do).

sommerfeld 6b88a0fc51 Emulation stackgap sanity checks, based partly on fixes from
FreeBSD-SA00:42.

Change stackgap_alloc to bounds-check the allocation vs. the stack
gap, returning NULL if there isn't room for the allocation.

Change emul_find() to check for a NULL return from stackgap_alloc()
and convert that into ENAMETOOLONG.

Reorder various emulation syscalls so that all *_CHECK_ALT_{EXIST,CREAT}
calls (which turn into emul_find() under the covers come *after* small,
fixed-size stackgap_alloc() calls.

Clean up ibcs2 {get,set}groups.

thorpej 4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.

syscalls.master files.  (you need to regenerate after checking in
syscalls.master to get the correct ids.)

tv 1d8f5f2ea3 Pretend to do something useful (just fill in oldsigaction with SIG_IGN and
zeroes) if the mapped signal number comes up zero.  Previously, sigaction1()
would return an error, confusing some linux apps trying to set handlers for
"all" signals.

thorpej e03e9e8086 Rather than starting init and creating kthreads by forking and then
doing a cpu_set_kpc(), just pass the entry point and argument all
the way down the fork path starting with fork1().  In order to
avoid special-casing the normal fork in every cpu_fork(), MI code
passes down child_return() and the child process pointer explicitly.

This fixes a race condition on multiprocessor systems; a CPU could
grab the newly created processes (which has been placed on a run queue)
before cpu_set_kpc() would be performed.

jhawk 78732e454b Remove conditionization upon XSERVER -- all the code
so conditionalized is already conditionalized on (NWSDISPLAY > 0),
so is wscons-specific. wscons has no conditionalization on XSERVER;
neither should the linux compatibility code.

Removing this is necessary to keep linux X server emulation functionining
after GENERIC rev 1.337 removing "options XSERVER" (relegating it
to the pccons/pcvt-specific, and therefore depricated).

thorpej 7b918b4088 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

jdolecek 600be45ffc Improve emulation of SIOCGIFHWADDR ioctl:
* when finding an interface, try the real name first before faking eth*
 * Linux kernel returns ENODEV if the request goes to unknown interface,
   so do the same here

This change makes Linux ICA client work.
