06cfa55694 [ARM] 4524/1: S3C: Move register out of include/asm-arm/arch-s3c2410
Move register and other definitions out of the
include/asm-arm/arch-s3c2410 into the the arch
directories of include/asm-arm/plat-s3c24xx and
include/asm-arm/plat-s3c.

This move is in preperation of the merging of
s3c2400 and s3c6400.

The following git mv commands are needed before
this patch can be applied:

20c2df83d2 mm: Remove slab destructors from kmem_cache_create().
Slab destructors were no longer supported after Christoph's
c59def9f22 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).

5f47c7eac6 coda breakage
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.
Renamed coda ones; in principle UML probably ought to do rename as
well, but that's another story.

89636af25d ide: add support for SCSI ioctls to ide-floppy
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).

1c164acf50 serverworks: fix DMA
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.

* 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()

* Enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes
  from siimage_speedproc()

* Bump driver version.

485efc6cf5 atiixp: PIO mode setup fixes
* Split off exisiting atiixp_tuneproc() into atiixp_tune_pio()
  and then add setting device PIO mode to atiixp_tuneproc().

* Add missing ide_get_best_pio_mode() call to atiixp_tuneproc() so
  "pio" == 255 (autotune) is handled correctly and "pio" values > 4 && < 255
  are filtered to PIO4 (previously "pio" == 5 could result in wrong timings
  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.

9702b5d5c2 ide: Stop mapping ROMs
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.

The two CONFIG variables

        CONFIG_ETRAX_IDE_CSE1_16_RESET
        CONFIG_ETRAX_IDE_CSP0_8_RESET

appear to have been dead since way back in 2.5.xx days:

2d9ce177e6 i386: Allow KVM on i386 nonpae
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).
