when some modes are unable to determine the link speed of a slave

This fixes the mincore syscall in three ways:

 (1) It moves as much argument checking outside of the semaphore-holding
     region as possible.

 (2) It checks the region parameters against TASK_SIZE so that a 32-bit binary
     on a 64-bit platform will get the right error when calling this syscall
     on a region that overlaps the end of the 32-bit address space.

 (3) It tidies up the VMA checking loop a little.

It adds the sleep support for newer powermacs, improve power saving on some
laptops, makes use of the new fbdev modelist management routines, and fixes
a few backlight related issues.

I tested it on a thinkpad T30 and a few PPC boxes with success.  It should
be less invasive than the previous one (I don't try to restore the mode on
exit, that is what breaks the thinkpad and possibly other stuffs that boot
in VGA text mode), plus fixed a couple of bugs in the mode detection code. 
I also reverted the memory map fix on ppc since it doesn't work properly on
some recent laptops where the firmware sets a tiled display.  I'll rework
that completely to update the memory map as part of the mode setting later.
That should fix various issues when switching with X/DRI on x86.

The new PowerMac sleep code provides an arch hook that can be used by video
drivers on laptops to bring back the screen very early, pretty much before
anything else.  This basically turns reports of the style "my laptop doesn't
wakeup" to "I get this or this oops/error/panic on wakeup", making fixing the
PM related bugs possible on a whole range of them.

However, the fbdev wakeup code triggers WARN_ON's in the VT subsystem if
called without the console semaphore when redrawing the screen (I added those
warnings a couple of kernel versions ago), and we can't call
acquire_console_sem() since we are so early in the wakeup process that we are
considered as in_atomic() (we hold irqs off too).

This patch addds a try_acquire_console_sem() function that can be used by
those video drivers that implement this early wakeup hook.  If the acquire
fails (which should never happen in practice), wakeup is delayed to the normal
PCI callback which does a blocking acquire_console_sem().

In linux 2.6, PTRACE_SETOPTIONS is redefined to 0x4200, while the old 2.4
value (21) is still available as PTRACE_OLDSETOPTIONS.

So, if UML uses PTRACE_SETOPTIONS, an UML-kernel built on a 2.6 won't run
on a 2.4 host.  Hence we must use PTRACE_OLDSETOPTIONS.

For cases when PTRACE_OLDSETOPTIONS does not exists (i.e.  2.4 host or
archs which miss it because they don't have a "deprecated" value), we
fallback this macro to PTRACE_SETOPTIONS.

some characters have different code from the code in updated table of MS.

the code is U+FA1B in nls_cp936.c.

Another fix to the put_chip() concurrency logic.

Problem was occurring when:

1) one thread was erasing a block in partition x;
2) another thread suspended the erase in order to write to
   partition y;
3) a third thread came along to read a different block from
   partition x and, when it called put_chip(), chip->oldstate was
   FL_ERASING and the erase (mistakenly) resumed;
4) the write in partition y obviously failed at that point.

Incidentally, the fix for this problem also fixed the case where
suspending writes for MTD XIP usage was not working properly.

1. FAN Status/Control: you can now get the fan status (running or not) and
   also set the fan speed (for <5 seconds only). The problem is that there
   is an auto regulator that kicks in within about 5 seconds after that to
   restart the fan if it is above a threshold temperature (39 Degree C in
   my Vaio). It is useful just to get the fan status (primarily). It also
   appears that you can change the speed by increasing the values (much
   like the LCD control) - there are effectively only about 6 speeds (it
   seems - not sure, but from what I've played with on my Vaio).

2. Temperature: you can get the current temperature (same as reported by
   ACPI). This is primarily useful for APM users (since ACPI already gives
   this). I have used this to detect when the fan comes on in my Vaio (39
   Degree C).
