ide-floppy: use drive->pc_callback instead of pc->callback
It is important that drive->pc_callback is set prior to enabling IRQs on the
device since this is called from the IRQ handler. Otherwise it hurts as I learnt
the hard way from the several "Kernel panic - not synching: Fatal exception in
interrupt" during the weekend :).

ide: push pc callback pointer into the ide_drive_t structure
Refrain from carrying the callback ptr with every packet command since the
callback function is only one anyways. ide_drive_t is probably not the most
suitable place for it right now but is the more sane solution. Besides, these
structs are going to be reorganized anyways during the generic ide rewrite.
Add ide_host_add() helper which does ide_host_alloc()+ide_host_register(),
then convert ide_setup_pci_device[s](), ide_legacy_device_add() and some
host drivers to use it.
While at it:
* Fix ide_setup_pci_device[s](), ide_arm.c, gayle.c, ide-4drives.c,
macide.c, q40ide.c, cmd640.c and cs5520.c to return correct error value.
* -ENOENT -> -ENOMEM in rapide.c, ide-h8300.c, ide-generic.c, au1xxx-ide.c
and pmac.c
* -ENODEV -> -ENOMEM in palm_bk3710.c, ide_platform.c and delkin_cb.c
* Reserve memory resources for all IDE ports at once by moving
request_mem_region() out of 'for ()' loop and always defining
GAYLE_IDEREG_SIZE to 0x2000.
* Keep memory resources even if no free IDE slots can be found
(this driver is unloadable currently).
ide: filter out "default" transfer mode values in set_xfer_rate()
* Filter out "default" transfer mode values (0x00 - default PIO mode,
0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted
/proc/ide/hd?/settings:current_speed setting.
Allowing "default" transfer mode values is a dangerous thing to do as
we don't support programming controller to the "default" transfer mode
and devices often use different values for the default and maximum PIO
mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay
programmed for higher PIO mode while device will use the lower PIO mode.
There is no functionality loss as by using special IOCTLs device can
still be programmed to "default" transfer modes (it is only useful for
debugging/testing purposes anyway).
* Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was
previously used by few host drivers to program the controller to PIO0
timings for "default" transfer mode == 0x01 (although some host drivers
would program invalid PIO timings instead).
* Cleanup ide_set_xfer_rate() and add BUG_ON().

ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3)
* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert
host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use
it instead of calling ide_init_port_hw() directly.
[ However if host has > 1 port we must still set hwif->chipset to hint
consecutive ide_find_port() call that the previous slot is occupied. ]
* Unexport ide_init_port_hw().
v2:
* Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c.
(Suggested by Geert Uytterhoeven)
* Better patch description.
v3:
* Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell)
There should be no functional changes caused by this patch.

My copying of linux/init.h didn't go far enough. The definition of
__used singled out gcc minor version 3, but didn't care what the major
version was. This broke when unit-at-a-time was added and gcc started
throwing out initcalls.
This results in an early boot crash when ptrace tries to initialize a

kgdb, powerpc: arch specific powerpc kgdb support
This patch removes the old kgdb reminants from ARCH=powerpc and
implements the new style arch specific stub for the common kgdb core
interface.
It is possible to have xmon and kgdb in the same kernel, but you
cannot use both at the same time because there is only one set of
debug hooks.
The arch specific kgdb implementation saves the previous state of the
debug hooks and restores them if you unconfigure the kgdb I/O driver.
Kgdb should have no impact on a kernel that has no kgdb I/O driver

This patch completely removes the dependency of usbkbd and usbmouse drivers

usbkbd/usbmouse drivers are not needed in the vast majority of cases anyway,

two I have. I tested this using evtest and a GTK application. A similar

This is alternative implementation of sg content iterator introduced
by commit 83e7d317... from Pierre Ossman in next-20080716. As there's
already an sg iterator which iterates over sg entries themselves, name
this sg_mapping_iterator.
Slightly edited description from the original implementation follows.
Iteration over a sg list is not that trivial when you take into
account that memory pages might have to be mapped before being used.
Unfortunately, that means that some parts of the kernel restrict
themselves to directly accesible memory just to not have to deal with
the mess.
This patch adds a simple iterator system that allows any code to
easily traverse an sg list and not have to deal with all the details.
The user can decide to consume part of the iteration. Also, iteration
can be stopped and resumed later if releasing the kmap between
iteration steps is necessary. These features are useful to implement
piecemeal sg copying for interrupt drive PIO for example.
