Jesper Nilsson 69b06c15e7 CRIS v32: Change drivers/i2c.c locking.
- Change spin_lock + local_irq_save into spin_lock_irqsave
- Change spin_unlock + local_irq_restore into spin_unlock_irqrestore
- Return ENOTTY if ioctl is not recognized as a cris ioctl.
- Make init functions static.

Jesper Nilsson a34d24425e CRIS v32: Rewrite ARTPEC-3 gpio driver to avoid volatiles and general cleanup.
Changes as suggested by Andrew Morton, plus general cleanup to
ease later consolidation of driver into machine common driver.

- Correct parameter type of gpio_write to const char __user *
- Remove volatile from the arrays of machine dependent registers, use
  readl and writel to access them instead.
- Remove useless casts of void.
- Use spin_lock_irqsave for locking.
- Break gpio_write into smaller sub-functions.
- Remove useless breaks after returns.
- Don't perform any change in IO_CFG_WRITE_MODE if values are invalid.
  (previously values were set and then set to zero)
- Change cast for copy_to_user to (void __user *)
- Make file_operations gpio_fops static and const.
- Make setget_output static. (However, it's still inline since the CRIS
  architecture is still not SMP, which makes the function small enough
  to inline)

Jesper Nilsson 9f68ff9ee9 CRIS v32: Clean up nandflash.c for ARTPEC-3 and ETRAX FS.
Clean up issues noticed by Andrew Morton:

- Use a combined struct for allocating the mtd_info and nand_chip structs
  instead of using anonymous memory as the example in
  Documentation/DocBook/mtdnand.tmpl
- Use kzalloc instead of using kmalloc/memset(0)
- Make crisv32_device_ready static.

Jesper Nilsson 7edf744053 CRIS v32: Update driver for RTC chip pcf8563.
- Moved all calls to register_chrdev to a function called by module_init.
- Added mutex locking.
- Added better error handling at start up.
- Added BIN_TO_BCD of the month value before it is saved to the RTC.
- Corrected the month value returned by pcf8563_readreg.
- Cache the voltage low value at driver init so the battery status
  information does not get 'accidentally' cleared when setting the RTC time.
- Removed obsolete CONFIG_ETRAX_RTC_READONLY
- Voltage low ioctl():s RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR

Jesper Nilsson 2d33d563b1 CRIS: avoid using arch links in Kconfig
Improve including of architecture dependent Kconfig files.

- Always include the architecture dependent Kconfig files.
- Wrap architecture dependent Kconfig files inside an appropriate
  "if ETRAX_ARCH_Vxx" block.

This makes it possible to run the configuration even without the arch links,
which are created later in the build process.

Greg Kroah-Hartman 52840bd628 Kobject: the cris iop_fw_load.c code is broken
This code is really really really broken.  So much so that it's almost
impossible to fix with a simple patch, so just comment out the offending
registration with the kobject core, and mark the driver as broken.

The problem is that the code is trying to register a "raw" struct
device, which is not allowed.  struct device is only for use within the
driver model.  This is being done to try to use the firmware layer which
wants a struct device.  To properly fix this, use something easy, like a
platform device, which is a struct device and can be used for this kind
of thing.

Some host drivers depend on CONFIG_IDE_GENERIC to do the probing but their
config options lack explicit dependencies on IDE_GENERIC.  In the long-term
these host drivers should be fixed to do the probing themselves but for now
fix them by making their config options select CONFIG_IDE_GENERIC.

Eric W. Biederman bba6f6fc68 [PATCH] MSI-X: fix resume crash
So I think the right solution is to simply make pci_enable_device just
flip enable bits and move the rest of the work someplace else.

However a thorough cleanup is a little extreme for this point in the
release cycle, so I think a quick hack that makes the code not stomp the
irq when msi irq's are enabled should be the first fix.  Then we can
later make the code not change the irqs at all.

Christoph Lameter 68402ddc67 [PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHM
Remove VM_LOCKED before remap_pfn range from device drivers and get rid of
VM_SHM.

remap_pfn_range() already sets VM_IO.  There is no need to set VM_SHM since
it does nothing.  VM_LOCKED is of no use since the remap_pfn_range does not
place pages on the LRU.  The pages are therefore never subject to swap
anyways.  Remove all the vm_flags settings before calling remap_pfn_range.

After removing all the vm_flag settings no use of VM_SHM is left.  Drop it.

Andrew Morton 4741c9fd36 [PATCH] set_page_dirty() return value fixes
We need set_page_dirty() to return true if it actually transitioned the page
from a clean to dirty state.  This wasn't right in a couple of places.  Do a
kernel-wide audit, fix things up.

This leaves open the possibility of returning a negative errno from
set_page_dirty() sometime in the future.  But we don't do that at present.

Olaf Hering 733482e445 [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason
This patch removes almost all inclusions of linux/version.h.  The 3
#defines are unused in most of the touched files.

A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.

There are also lots of #ifdef for long obsolete kernels, this was not
touched.  In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

search pattern:
/UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h
