24a96ae0e3 siimage: do clocking register posting earlier in setup_mmio_siimage()
Do clocking register posting earlier in setup_mmio_siimage()
to match code in init_chipset_siimage().

This is a preparation for the next patch which merges PCI and MMIO
code paths together.

16bb69c14a ide: remove ->INS{W,L} and ->OUTS{W,L} methods
* Use ins{w,l}()/outs{w,l}() and __ide_mm_ins{w,l}()/__ide_mm_outs{w,l}()
  directly in ata_{in,out}put_data() (by using IDE_HFLAG_MMIO host flag to
  decide which I/O ops are required).

* Remove no longer needed ->INS{W,L} and ->OUTS{W,L} methods (ide-h8300,
  au1xxx-ide and scc_pata implement their own ->{in,out}put_data methods).

There should be no functional changes caused by this patch.

c5dd43ec65 ide: add IDE_HFLAG_MMIO host flag (take 2)
* Add IDE_HFLAG_MMIO host flag and set it for hosts which use
  default_hwif_mmiops().

v2:
* Fix kernel panic in pmac host driver (',' should be '|').

  Thanks to Kamalesh for reporting it + testing the fix
  and to Andrew for hinting me about the source of the issue.

9567b349f7 ide: merge ->atapi_*put_bytes and ->ata_*put_data methods
* Merge ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods
  into new ->{in,out}put_data methods which take number of bytes to
  transfer as an argument and always do padding.

While at it:

* Use 'hwif' or 'drive->hwif' instead of 'HWIF(drive)'.

There should be no functional changes caused by this patch (all users
of ->ata_{in,out}put_data methods were using multiply-of-4 word counts).

92d3ab27e8 falconide/q40ide: add ->atapi_*put_bytes and ->ata_*put_data methods (take 2)
* Add ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods to
  falconide and q40ide host drivers (->ata_* methods are implemented on
  top of ->atapi_* methods so they also do byte-swapping now).

* Cleanup atapi_{in,out}put_bytes().

v2:
* Add 'struct request *rq' argument to ->ata_{in,out}put_data methods
  and don't byte-swap disk fs requests (we shouldn't un-swap fs requests
  because fs itself is stored byte-swapped on the disk) - this is how
  things were done before the patch (ideally device mapper should be
  used instead but it would break existing setups and would have some
  performance impact).

fcbd3b4b92 [MIPS] Pb1200/DBAu1200: move platform code to its proper place
Since both the IDE interface and SMC 91C111 Ethernet chip are on-board
devices, not SOC devices, move the platform device registration form the
common to the board specific code.

While at it, remove semicolon (which didn't break compilation only by
chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming:

- change 'au1200_ide0_' variable name prefix to the mere 'ide_';

- change 'smc91x_' variable name prefix to 'smc91c111_' since that's the
  name of the chip used on the boards;

- drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet
  on-board devices;

- change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of
  the macros describing the Ethernet chip for consistency with the IDE
  macros;

- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is
  indeed a shift count) in the names of the macros describing the IDE
  interface.

d7a420c947 raid: remove leading TAB on printk messages
MD drivers use one printk() call to print 2 log messages and the second line
may be prefixed by a TAB character.  It may also output a trailing space
before newline.  klogd (I think) turns the TAB character into the 2 characters
'^I' when logging to a file.  This looks ugly.

Instead of a leading TAB to indicate continuation, prefix both output lines
with 'raid:' or similar.  Also remove any trailing space in the vicinity of
the affected code and consistently end the sentences with a period.

8b3e6cdc53 md: introduce get_priority_stripe() to improve raid456 write performance
Improve write performance by preventing the delayed_list from dumping all its
stripes onto the handle_list in one shot.  Delayed stripes are now further
delayed by being held on the 'hold_list'.  The 'hold_list' is bypassed when:

  * a STRIPE_IO_STARTED stripe is found at the head of 'handle_list'
  * 'handle_list' is empty and i/o is being done to satisfy full stripe-width
    write requests
  * 'bypass_count' is less than 'bypass_threshold'.  By default the threshold
    is 1, i.e. every other stripe handled is a preread stripe provided the
    top two conditions are false.

Benchmark data:
System: 2x Xeon 5150, 4x SATA, mem=1GB
Baseline: 2.6.24-rc7
Configuration: mdadm --create /dev/md0 /dev/sd[b-e] -n 4 -l 5 --assume-clean
Test1: dd if=/dev/zero of=/dev/md0 bs=1024k count=2048
  * patched:  +33% (stripe_cache_size = 256), +25% (stripe_cache_size = 512)

Test2: tiobench --size 2048 --numruns 5 --block 4096 --block 131072 (XFS)
  * patched: +13%
  * patched + preread_bypass_threshold = 0: +37%

Changes since v1:
* reduce bypass_threshold from (chunk_size / sectors_per_chunk) to (1) and
  make it configurable.  This defaults to fairness and modest performance
  gains out of the box.
Changes since v2:
* [neilb@suse.de]: kill STRIPE_PRIO_HI and preread_needed as they are not
  necessary, the important change was clearing STRIPE_DELAYED in
  add_stripe_bio and this has been moved out to make_request for the hang
  fix.
* [neilb@suse.de]: simplify get_priority_stripe
* [dan.j.williams@intel.com]: reset the bypass_count when ->hold_list is
  sampled empty (+11%)
* [dan.j.williams@intel.com]: decrement the bypass_count at the detection
  of stripes being naturally promoted off of hold_list +2%.  Note, resetting
  bypass_count instead of decrementing on these events yields +4% but that is
  probably too aggressive.
Changes since v3:
* cosmetic fixups

0e170c72c0 fbdev: intelfb: add support for the Intel Integrated Graphics Controller 965G/965GM
Add support for the 965G and 965GM graphic chipsets to the intelfb driver.  I
have a notebook with an Intel Mobile GM965/GL960 Integrated Graphics
Controller and with the attached patch the framebuffer comes up.  I have
tested it a bit with DirectFB to make sure it is working stable.

I also have an Intel Mobile GM945 and I compared the results, the programming
interface of the 9xx series from Intel is mostly the same, so I think the
patch should add all the functionality which the 945GM has.

0aa163418e fb: convert /proc/fb to seq_file interface
Note: looks like accesses to "registered_fb" are done without any exclusion
so there're none in new proc code, too. This should be fixed in separate
patch.

9b53a9e28a fbdev: powerpc: driver for Freescale 8610 and 5121 DIU
The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIs

All /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0.  Changing pixel clock has no effect
on other fbs.

Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
AOIs can not beyond phisical display area. Application should check AOI geometry
before changing physical resolution on /dev/fb0

required command line parameters to preallocate memory for frame buffer diufb.

optional command line parameters to set modes and monitor
video=fslfb:[resolution][,bpp][,monitor]
Syntax:

Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60

Bpp
bpp=32, bpp=24, or bpp=16

Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS

Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.

If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

3553a2fa8c OLPC: gxfb/lxfb: add DCON panel modes to framebuffer drivers
Since there's no way to autodetect panel modes, we're forced to hardcode them
in the driver and add a big fat #ifdef.  The OLPC DCON needs a specific mode
line (at 1200x900).  This adds it to both gxfb and lxfb.

(Jordan said: We could probably detect the panel mode, but there isn't any
reason to since the panel timings are well known and won't change.  While OFW
detection would be good computer science fu, it would be a wasted effort since
its so easy to hard code them into the table.)

fd96795630 gxfb/lxfb: detect framebuffer size using an MSR if VSA2 isn't available
If there's no VSA2 (ie, if we're using tinybios or OpenFirmware), use the
GLIU's P2D Range Offset Descriptor to determine how much memory we have
available for the framebuffer.

Originally based on a patch by Jordan Crouse.  Tested with OpenFirmware;
Pascal informs me that tinybios has a stub that fills in P2D_RO0.
