This patch unifies the cpu specific interrupt setup functions for
interrupt controller blocks such as ipr, intc2 and intc. There is no
point in having separate functions for each interrupt controller, so
let's clean this up.Signed-off-by: Magnus Damm

This patch cleans up solution engine 7722 specific interrupt code.
The main purpose is to replace the mux function with use of
set_irq_chained_handler() and replace hard coded register poking
code with set_irq_type(). The board specific interrupts are also
moved to start from SE7722_FPGA_IRQ_BASE.Signed-off-by: Magnus Damm

This patch converts the cpu specific 7722 setup code to use the
new intc controller. Many new vectors are added and also support
for external interrupt sense configuration. So with this patch
it is now possible to configure external interrupt pins as edge
or level triggered using set_irq_type().Signed-off-by: Magnus Damm

This is the second version of the shared interrupt controller patch
for the sh architecture, fixing up handling of intc_reg_fns[].The three main advantages with this controller over the existing
ones are:- Both priority (ipr) and bitmap (intc2) registers are
supported
- External pin sense configuration is supported, ie edge
vs level triggered
- CPU/Board specific code maps 1:1 with datasheet for
easy verificationThis controller can easily coexist with the current IPR and INTC2
controllers, but the idea is that CPUs/Boards should be moved over
to this controller over time so we have a single code base to
maintain.Signed-off-by: Magnus Damm

This patch contains two serial port related fixes for sh7722:
- Make sure the irqs for the first serial port is correct

* 'kmem_death' of master.kernel.org:/pub/scm/linux/kernel/git/lethal/sh-2.6:
mm: Remove slab destructors from kmem_cache_create(). -
Change in 'kbuild: do section mismatch check on full vmlinux'
should've been replicated in arch/um/Makefile.Signed-off-by: Al Viro
Signed-off-by: Linus Torvalds -
Slab destructors were no longer supported after Christoph's
c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
BUGs for both slab and slub, and slob never supported them
either.This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).Signed-off-by: Paul Mundt

a) switch by loff_t == __cmpdi2 use. Replaced with a couple
of obvious ifs; update of ->f_pos in the first one makes sure that we
do the right thing in all cases.
b) block_signals() and unblock_signals() are globals on UML.

well, but that's another story.Signed-off-by: Al Viro

Now that ide-floppy supports SG_IO we can add support for SCSI ioctls
(except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET
ones - we can add them later iff really needed).While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from
generic_ide_ioctl():- This prevents ide-{disk,tape,scsi} device drivers from obtaining
REQ_TYPE_BLOCK_PC type requests which are currently unsupported by
these drivers and which are potentially harmful (as reported by Andrew).- There is no functionality loss since aforementioned ioctls will now be
handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using
ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl()
(for devices using ide-cd driver).Cc: Jens Axboe

* Nowadays core IDE code handles restoring of PIO and DMA modes
(ide-io.c:ide_start_power_step() etc) so remove open-coded version
from sc1200_resume().There should be no change in behavior because settings done by
sc1200_resume() were always overridden by generic_ide_resume()
and ide_{start,stop}_power_step().* Bump driver version.

* Do the same thing as probe_hwif() and always disable DMA so chipset DMA
enabled bit gets cleared (if the drive doesn't support DMA ide_set_dma()
won't try to tune it anyway).* Add TODO comment about respecting ->using_dma setting.

The driver used to depend on BIOS settings for deciding whether it is OK
to use DMA. However it seems that BIOS doesn't always handle all cases
correctly so just let IDE core to decide about this. It should be a safe
thing to do now, after the driver went through heavy bugfixing.Thanks for bugreport and testing the patch goes out to Sven Niedner.

* Always set ->autotune so PIO gets correctly auto-tuned (previously
->autotune was only set when ->dma_base wasn't available, however
->ide_dma_check()/->speedproc() was always trying to tune PIO when
tuning DMA).* Move code responsible for programming chipset for PIO mode from
svwks_tune_chipset() to svwks_tune_pio(). Don't tune PIO when tuning
DMA (this is no longer needed since ->autotune is always set now).* Handle PIO modes early in svwks_tune_chipset() so DMA configuration
registers don't get cleared when programming PIO mode.* Bump driver version.

* Add sil_tuneproc() wrapper for siimage_tuneproc() which also sets
PIO mode on the device.* Add missing ide_get_best_pio_mode() call to sil_tuneproc() so
"pio" == 255 (autotune) is handled correctly (previously PIO0 was used)
and "pio" values > 4 && < 255 are filtered to PIO4 (instead of PIO0).* Add code limiting maximum PIO mode according to the pair device capabilities
to sil_tuneproc().* Convert users of config_siimage_chipset_for_pio() to use sil_tune_pio() and
sil_tuneproc(). This fixes PIO fallback in siimage_config_drive_for_dma() to
use max PIO mode available instead of PIO4 (config_siimage_chipset_for_pio()
used wrong arguments for ide_get_best_pio_mode() and as a results always
tried to set PIO4).* Remove no longer needed siimage_taskfile_timing()
and config_siimage_chipset_for_pio().* Enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes
from siimage_speedproc()* Bump driver version.
v2:
* Fix issues noticed by Sergei:

being used and "pio" values > 4 && < 255 in an OOPS).* Handle PIO modes early in atiixp_speedproc() so save_mdma_mode[]
doesn't get cleared.* In atiixp_dma_check():
- fix max_mode argument for ide_get_best_pio_mode()
- don't call atiixp_dma_2_pio() so PIO1 doesn't get remapped to PIO0
- use atiixp_tuneproc() instead of atiixp_speedproc()* Bump driver version.

Various old IDE drivers go mapping ROM devices for no apparent reason and
without using the ROM mapping API we now have. They don't actually use
the ROM they map and the new libata drivers are happy without it being
mapped so rather than port them lets just junk it for the next -rc1.Signed-off-by: Alan Cox

Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of
the cmpxchg64b feature and enables compilation of the set_64bit() family.
Since the option is dependent on PAE, and since KVM depends on set_64bit(),
this effectively disables KVM on i386 nopae.Simplify by removing the config option altogether: the boot check is made
dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed
without constraints. It is up to users to check for the feature flag (KVM
does not as virtualiation extensions imply its existence).Signed-off-by: Avi Kivity
