This is the patch (based on 2.6.19-rc4) for PATA controller of
Toshiba Cell reference set(Celleb). The reference set consists
of Cell, 512MB memory, Super Companion Chip(SCC) and some
peripherals such as HDD, GbE, etc. You can see brief explanation
and picture of Cell reference set at following URLs.

We use a drivers/ide driver because its design is more suitable for
SCC IDE controller than libata driver. Since SCC supports only 32bit
read/write, we must override many callbacks of ata_port_operations
by modifying generic helpers. Each time the libata common code is
updated, we must update those modified helpers. It is very hard for us.
But we will try to implement the libata driver as needed.

Fix a number of issues with the DMA support code:
- driver claims support for all SW/MW DMA modes while supporting only MWDMA2;
- ide_dma_check() method tries to enable DMA on the "known good" drives which
don't support MWDMA2;
- ide_dma_on() method upon failure to set drive to MWDMA2 re-tunes already
tuned PIO mode and calls ide_dma_off() method instead of returning error;
- ide_dma_off() method sets drive->current_speed while it doesn't actually
change (only the PIO timings are re-loaded into the chip's registers);
- init_hwif() method forcibly sets/resets both "drive DMA capable" bits while
this is properly handled by ide_dma_{on,off}() methods being called later...

A ZIP or similar with unformatted media will cause crashes when attempts
are made to read/write it in some cases. This is because bs_factor is
zero and we divide by it causing an oops.
As the size of a non-accessible/non-existant media is really a bit of a
zen question it doesn't matter if non-existant media is 512 bytes per
sector or zero. Setting it to 1 causes us to generate 512 bytes/sector
accesses and error properly.

* jmicron: if DMA can't be used config_chipset_for_dma() should return 0,
micron_config_drive_for_dma() will tune the correct PIO mode anyway
config_jmicron_chipset_for_pio(drive, !speed) doesn't program

Above changes also fix (theoretical) issue when ->speedproc fails to set
device transfer mode (i.e. when ide_config_drive_speed() fails to program it)
but one of DMA transfer modes is already enabled on the device by the BIOS.
In such scenario ide_dma_enable() will incorrectly return true statement

This patch updates the sata_promise driver to use new-style
libata error handling for 20619 (TX4000) chips. sata_promise
already uses new EH for the other chips it supports, so the
patch is quite simple:
* remove ->phy_reset and ->eng_timeout ops from pdc_pata_ops,
and instead bind ->freeze, ->thaw, ->error_handler, and
->post_internal_cmd to existing new EH functions
* drop ATA_FLAG_SRST from board_20619's flags
* remove now unused pdc_pata_phy_reset() and pdc_eng_timeout()
Tested on a TX4000 with both modern working disks and old/quirky
disks. Also used a CD-RW drive to test reading and writing CDs.

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name. Which is
pain for caching and the proc interface never implemented.
I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.
So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

There is no need for open files in /proc/sys/XXX to hold a reference count on
the module that provides the file to prevent module unload races. While there
is code active in the module p->used in the sysctl_table_header is
incremented, preventing the sysctl from being unregisted. Once the sysctl is
unregistered it cannot be found. Open files are also not a problem as they
revalidate the sysctl information and bump p->used before accessing module
code.
So setting de->owner is unnecessary, makes for a bad example and gets in my
way of removing ctl_table->de.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).
