sommerfeld 7e7d262c34 Add %fs/%gs to trap frame and save/restore them on
trap/interrupt/syscall entry from userspace.

Remove special-case "by hand" validation of fs/gs register values as
well as special handling of them in various signal handling paths.

Now, like %ds and %es, they are validated by the hardware on return to
userland.

This paves the way for the use of %fs for per-cpu data on
multiprocessor systems, and fixes an otherwise difficult-to-fix
interaction between threads/clone(2) and USER_LDT.

Discussed in advance with Frank van der Linden.

thorpej 80cc38a1af Fix a partial construction problem that can cause race conditions
between creation of a file descriptor and close(2) when using kernel
assisted threads.  What we do is stick descriptors in the table, but
mark them as "larval".  This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again.  When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.

While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.

manu d473f5bd8a Improved the accuracy of gettimeofday/settimeofday: Linux stores a srtuct
timezone in the kernel. We now keep track of it for emulated processes.
Tested for powerpc and i386. Untested on m68k, but it should be ok
Alpha has a particular implementation (osf1_sys_gettimeofday), and it has
therefore not been touched.

jdolecek 890850dddf Implement linux_sys_nosys() and use it instead of sys_nosys() for
unimplemented syscalls. Difference is that linux_sys_nosys() doesn't
post SIGSYS to the process. Linux doesn't do that and thus glibc (and
probably other Linux code) doesn't deal with SIGSYS, even through it
generally contains fallback code for ENOSYS case.

This also addresses port-i386/12503, though the issue was already discussed
earlier.

fvdl b930296d07 Under Linux it's possible to return values through the ioctl system
call directly (i.e. not a reference argument, but a direct return
value). So far I have only seen this with binaries that talk
to their own device modules, using non-standard ioctl calls.
Hence, allow for a pass-through ioctl call using PTIOCLINUX to
return EJUSTRETURN, signalling that the return value is in
the 'data' field of the structure, which can then be put in 'retval'.

    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

erh f96aee80d6 Make the linux compatibilty code work on the alpha. (horay!) (at last!)
Two main changes:
	Create a linux_elf64_copyargs that uses the linux specific LinuxAuxInfo
	structure.  This is only used on the alpha.  i386 and m68k use the
	standard elf copyargs function.

	Since linux's approach to binary compatibilty is to look as much
	like osf1 as possible, add all the osf1 syscalls that we have
	implemented to the linux syscall table.  This includes get/setsysinfo,
	ported from FreeBSD.

In order for linux compat to work you must have COMPAT_OSF1, COMPAT_43,
COMPAT_09, COMPAT_12 and COMPAT_13 on also.

syscalls.master to get the correct ids.)

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).
