x86-64 vsyscalls require mapping the sequence number used by
gettimeofday in a magic way, so that userland can access it via
vsyscalls for user space time-of-day access.

Instead of putting the magic into generic code I just allowed to move it
into architecture specific files.

Fix some annoying warnings that happen on x86-64.

 - Predeclare pt_regs in binfmts.h.  For some reason it isn't included
   implicitely there.
 - use unsigned long, not long for interrupt flags in posix-timers.c

This still has a few problems; e.g. posix-timers.c seems to be miscompiled
by many x86-64 compilers when compiled with -O1. But overall it is better
than before.

 - Disable numa again that was enabled by mistake
 - Fix CPU detection in early boot. Force SSE when needed.
 - Hack for nested NMIs.
 - Fix typo in vsyscall code that lead to broken time reporting
 - Merge with 2.5.62-bk4 (new switch_to, printk cleanups, new timer calls etc.)
 - Fix bug in strace - don't assume syscall_trace doesn't clobber %rcx
 - Fix gs load workaround
 - Fix return value of ioperm (found by new LTP test)
 - Remove some unecessary boot output
 - Remove some obsolete code in setup.c
 - Report more in /proc/cpuinfo, fix extended cpu family computation
 - Fix thread_info access from interrupt/exception stacks - this
   fixes many problems that especially showed on SMP (lost reschedule
   interrupts etc.)
 - Fix UP compilation
 - Symlink hugetlbpage.c from i386
 - Fix buggy lazy fpu handling

Older compilers require that automatic variable declarations appear at the
start of a block.

non-exit code.

Instead of detecting when filp->private_data becomes NULL in
do_tty_hangup and check_tty_count, we remove the file descriptor
from the list of descriptors associated with the tty.  We use the
same method that dentry_open() uses.

(It also cleans that up to use a "file_kill()" instead of using a dummy
"kill_list()" that leaves pointers to stale stack entries that are never
used)

In addition, we change the for() loops into real list_for_each()
or list_for_each_entry loops as appropriate.

The patch below removes an unneeded #if from net/ipv6/af_inet6.c:
- kernel 2.0 is too ancient to check for
- the MODULE_* macros have empty definitions #if !MODULE

Move printing the header to s_start, removing the need for the special
pointer value.

This patch moves over printing of the various struct Scsi_Host
attributes from procfs functions in the sg driver to sysfs.

Not only is this the much more logical place for them, but with some
more work on the pcmcia drivers this will allow us to make
scsi_host_get_next() private to the midlayer for implementing
refcounting and cleaning up locking in that area.

Do the test for -falign-xxx vs. -malign-xxx only once.

Kill unused variable.

Removes the now unused trap handler for double faults.  Also removes the
never used handler for fpu not available.
