14-eeh-device-bar-save.patch
After a PCI device has been resest, the device BAR's and other config
space info must be restored to the same state as they were in when
the firmware first handed us this device. This will allow the
PCI device driver, when restarted, to correctly recognize and set up
the device.
Tis patch saves the device config space as early as reasonable after
the firmware has handed over the device. Te state resore funcion
is inteded for use by the EEH recovery routines.

12-eeh-event-dispatcher.patch
ppc64: EEH Recovery dispatcher thread
This patch adds a mechanism to create recovery threads when an
EEH event is received. Since an EEH freeze state may be detected
within an interrupt context, we need to get out of the interrupt
context before starting recovery. This dispatcher does this in
two steps: first, it uses a workqueue to get out, and then
lanuches a kernel thread, so that the recovery routine can
sleep for exteded periods without upseting the keventd.
A kernel thread is created with each EEH event, rather than
having one long-running daemon started at boot time. This is
because it is anticipated that EEH events will be very rare
(very very rare, ideally) and so its pointless to cluter the
process tables with a daemon that will almost never run.

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.

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.

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.

->permission and ->lookup have a struct nameidata * argument these days to
pass down lookup intents. Unfortunately some callers of lookup_hash don't
actually pass this one down. For lookup_one_len() we don't have a struct
nameidata to pass down, but as this function is a library function only
used by filesystem code this is an acceptable limitation. All other
callers should pass down the nameidata, so this patch changes the
lookup_hash interface to only take a struct nameidata argument and derives
the other two arguments to __lookup_hash from it. All callers already have
the nameidata argument available so this is not a problem.
At the same time I'd like to deprecate the lookup_hash interface as there
are better exported interfaces for filesystem usage. Before it can
actually be removed I need to fix up rpc_pipefs.

When calling target drivers to set frequency, we take cpucontrol lock.
When we modified the code to accomodate CPU hotplug, there was an attempt
to take a double lock of cpucontrol leading to a deadlock. Since the
current thread context is already holding the cpucontrol lock, we dont need
to make another attempt to acquire it.
Now we leave a trace in current->flags indicating current thread already is
under cpucontrol lock held, so we dont attempt to do this another time.
Thanks to Andrew Morton for the beating:-)

save_and_disable_irqs does not need to use mov + msr (which was
introduced to work around a documentation bug which was propagated
into binutils.) Use msr with an immediate constant, and if we're
building for ARMv6 or later, use the new CPSID instruction.

Use __do_IRQ instead. The only difference is that every controller
is now assumed to have an end() routine (only xics_8259 did not).

You could open the /proc/sys/net/ipv4/conf/<if>/<whatever> file, then
wait for interface to go away, try to grab as much memory as possible in
hope to hit the (kfreed) ctl_table. Then fill it with pointers to your
function. Then do read from file you've opened and if you are lucky,
you'll get it called as ->proc_handler() in kernel mode.
So this is at least an Oops and possibly more. It does depend on an
interface going away though, so less of a security risk than it would
otherwise be.

Patch from Richard Purdie
The Sharp SL-Cxx00 models have a combined power control for the SD
and CF slot 0. This patch adds hooks to the scoop driver to allow
machines to provide a custom control function for this and such a
function is added for spitz/akita/borzoi.
It also moves the gpio init code into the machine files as this
is machine dependent and differs between some models. A couple of
warnings when compiling for collie are also fixed.

The patch below implements the Microsoft Point-to-Point Encryption method
as a PPP compressor/decompressor. This is necessary for Linux clients and
servers to interoperate with Microsoft Point-to-Point Tunneling Protocol
(PPTP) servers (either Microsoft PPTP servers or the poptop project) which
use MPPE to encrypt data when creating a VPN.
This patch differs from the kernel_ppp_mppe DKMS pacakge at
pptpclient.sourceforge.net by utilizing the kernel crypto routines rather
than providing its own SHA1 and arcfour implementations.
Minor changes to ppp_generic.c try to prevent a link from disabling
compression (in our case, the encryption) after it has started using
compression (encryption).
Feedback to <pptpclient-devel@lists.sourceforge.net> please.

This factors out the common bits of arch/powerpc/xmon/start_*.c into
a new nonstdio.c, and removes some stuff that was supposed to make
xmon's I/O routines somewhat stdio-like but was never used.
It also makes the parsing of the xmon= command line option common,
so that ppc32 can now use xmon={off,on,early} also.

This patch kills include/linux/eeprom.h .
Rationale:
- it was only used by one single driver
- even this driver didn't do anything useful with it
- most of this file are non-inline and non-static functions (sic)
This removes include/linux/eeprom.h and cleans drivers/net/ns83820.c up.
If you think eeprom.h should be used more extensively, please consider:
- the code has to be moved from the header file to a .c file
- the currently empty write function has to be implemented
- ns83820.c or any other driver should actually use it
Noone did any of these during the more than 3 years eeprom.h already
exists...
