This patch moves a bunch of files from arch/ppc64 and
include/asm-ppc64 which have no equivalents in ppc32 code into
arch/powerpc and include/asm-powerpc.  The file affected are:
	abs_addr.h
	compat.h
	lppaca.h
	paca.h
	tce.h
	cpu_setup_power4.S
	ioctl32.c
	firmware.c
	pacaData.c

The only changes apart from the move and corresponding Makefile
changes are:
	- #ifndef/#define in includes updated to _ASM_POWERPC_ form
	- trailing whitespace removed
	- comments giving full paths removed
	- pacaData.c renamed paca.c to remove studlyCaps
	- Misplaced { moved in lppaca.h

for 32-bit powermac (ARCH=powerpc).

Having already merged the ppc and ppc64 versions of signal.c, this
patch finishes the job by merging signal.h.  The two versions were
almost identical already.  Notable changes:
	- We use BITS_PER_LONG to correctly size sigset_t
	- Remove some uneeded #includes and struct forward
declarations.  This does mean adding an include to signal_32.c which
relied on the indirect inclusion of sigcontext.h
	- As the ppc64 version, the merged signal.h has prototypes for
do_signal() and do_signal32().  Thus remove extra prototypes from
ppc_ksyms.c which had them directly.

There are a few loose ends following the conversion of md to use kthreads:

- Some fields in mdk_thread_t that aren't needed (kthreads does it's own
  completion and manages it's own name).

- thread->run is now never NULL, so no need to check

- Some tests for signal_pending that aren't needed (As we don't use signals
  to stop threads any more)

- Some flush_signals are not needed

- Some waits are interruptible and don't need to be.

We can only accept BARRIER requests if all slaves handle
barriers, and that can, of course, change with time....

So we keep track of whether the whole array seems safe for barriers,
and also whether each individual rdev handles barriers.

We initially assumes barriers are OK.

When writing the superblock we try a barrier, and if that fails, we flag
things for no-barriers.  This will usually clear the flags fairly quickly.

If writing the superblock finds that BIO_RW_BARRIER is -ENOTSUPP, we need to
resubmit, so introduce function "md_super_wait" which waits for requests to
finish, and retries ENOTSUPP requests without the barrier flag.

When writing the real raid1, write requests which were BIO_RW_BARRIER but
which aresn't supported need to be retried.  So raid1d is enhanced to do this,
and when any bio write completes (i.e.  no retry needed) we remove it from the
r1bio, so that devices needing retry are easy to find.

We should hardly ever get -ENOTSUPP errors when writing data to the raid.
It should only happen if:
  1/ the device used to support BARRIER, but now doesn't.  Few devices
     change like this, though raid1 can!
or
  2/ the array has no persistent superblock, so there was no opportunity to
     pre-test for barriers when writing the superblock.

Each device in an md array how has a corresponding

directory which can contain attributes.  Currently there is only 'state' which
summarises the state, nd 'super' which has a copy of the superblock, and
'block' which is a symlink to the block device.

Also, /sys/block/mdX/md/rdNN represents slot 'NN' in the array, and is a
symlink to the relevant 'devNN'.  Obviously spare devices do not have a slot
in the array, and so don't have such a symlink.

This patch changes the behaviour of raid5 when it gets a read error.
Instead of just failing the device, it tried to find out what should have
been there, and writes it over the bad block.  For some media-errors, this
has a reasonable chance of fixing the error.  If the write succeeds, and a
subsequent read succeeds as well, raid5 decided the address is OK and
conitnues.

Instead of failing a drive on read-error, we attempt to re-write the block,
and then re-read.  If that all works, we allow the device to remain in the
array.

Add ability to set rotation via sysfs.  The attributes are located in
/sys/class/graphics/fb[n] and accepts 0 - unrotated; 1 - clockwise; 2 - upside
down; 3 - counterclockwise.

The attributes are:

con_rotate (r/w) -   set rotation of the active console
con_rotate_all (w) - set rotation of all consoles
rotate (r/w) -       set rotation of the framebuffer, if supported.
Currently, none of the drivers support this.

This is probably temporary, since con_rotate and con_rotate_all are
console-specific and has no business being under the fb device.  However,
until the console layer acquires it's own sysfs class, these attributes will
temporarily reside here.

This patch series implements generic code to rotate the console at 90, 180,
and 270 degrees. The implementation is completely done in the framebuffer
console level, thus no changes to the framebuffer layer or to the drivers
are needed.

Console rotation is required by some Sharp-based devices where the natural
orientation of the display is not at 0 degrees. Also, users that have
displays that can pivot will benefit by having a console in portrait mode
if they so desire.

The choice to implement the code in the console layer rather than in the
framebuffer layer is due to the following reasons:

- it's fast
- it does not require driver changes
- it can coexist with devices that can rotate the display at the hardware level
- it complements graphics applications that can do display rotation

The changes to core fbcon are minimal-- recognition of the console
rotation angle so it can swap directions, origins and axes (xres vs yres,
xpanstep vs ypanstep, xoffset vs yoffset, etc) and storage of the rotation
angle per display. The bulk of the code that does the actual drawing to the
screen are placed in separate files. Each angle of rotation has separate
methods (bmove, clear, putcs, cursor, update_start which is derived from
update_var, and clear_margins).  To mimimize processing time, the fontdata
are pre-rotated at each console switch (only if the font or the angle has
changed).

The option can be compiled out (CONFIG_FRAMEBUFFER_CONSOLE_ROTATION = n) if
rotation is not needed.

Choosing the rotation angle can be done in several ways:

1. boot option fbcon=rotate:n, where
     n = 0 - normal
     n = 1 - 90 degrees (clockwise)
     n = 2 - 180 degrees (upside down)
     n = 3 - 270 degrees (counterclockwise)

2. echo n > /sys/class/graphics/fb[num]/con_rotate

     where n is the same as described above. It sets the angle of rotation
of the current console

3 echo n > /sys/class/graphics/fb[num]/con_rotate_all

     where n is the same as described above. Globally sets the angle of
rotation.

GOTCHAS:

	The option, especially at angles of 90 and 270 degrees, will exercise
the least used code of drivers.  Namely, at these angles, panning is done
in the x-axis, so it can reveal bugs in the driver if xpanstep is set
incorrectly. A workaround is to set xpanstep = 0.

	Secondly, at these angles, the framebuffer memory access can be
unaligned if (fontheight * bpp) % 32 ~= 0 which can reveal bugs in the drivers
imageblit, fillrect and copyarea functions.  (I think cfbfillrect may have
this buglet). A workaround is to use a standard 8x16 font.

Speed:

	The scrolling speed difference between 0 and 180 degrees is minimal,
somewhere areound 1-2%.  At 90 or 270 degress, speed drops down to a vicinity
of 30-40%. This is understandable because the blit direction is across the
framebuffer "direction." Scrolling will be helped at these angles if xpanstep
is not equal to zero, use of 8x16 fonts, and setting xres_virtual >= xres * 2.

Note: The code is tested on little-endian only, so I don't know if it will
work in big-endian. Please let me know, it will take only less than a minute
of your time.

This patch prepares fbcon for console rotation and contains the following
changes:

- add rotate field in struct fbcon_ops to keep fbcon's current rotation
  angle

- add con_rotate field in struct display to store per-display rotation angle

- create a private copy of the current var to fbcon.  This will prevent
  fbcon from directly manipulating info->var, especially the fields xoffset,
  yoffset and vmode.

- add ability to swap pertinent axes (xres, yres; xpanstep, ypanstep; etc)
  depending on the rotation angle

- change global update_var() (function that sets the screen start address)
  as an fbcon method update_start.  This is required because the axes, start
  offset, and/or direction can be reversed depending on the rotation angle.

- add fbcon method rotate_font() which will rotate each character bitmap to
  the correct angle of rotation.

- add fbcon boot option 'rotate' to select the angle of rotation at bootime.
   Currently does nothing until all patches are applied.
