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'.
