With the newer compilers, size_t and ssize_t are expected to be (un)signed int
rather than (un)signed long.

A change to the RTC routines in the MN10300 arch used set_rtc_mms() when it
meant set_rtc_mmss(). This results in an error due to a reference of an
undefined symbol.

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6:
[IA64] Fix rwsem: RWSEM_WAITING_BIAS must not be unsigned.

Some nice improvements were made to rwsem in commit:
424acaaeb3a3932d64a9b4bd59df6cf72c22d8f3
rwsem: wake queued readers when writer blocks on active read lock
but this change overlooked that ia64 had defined RWSEM_WAITING_BIAS
as an unsigned value, while the new code required a signed value (as
it is in every other architecture).
This fix suggested by the original patch author: Michel Lespinasse.

of_device is just an alias for platform_device, so remove it entirely. Also
replace to_of_device() with to_platform_device() and update comment blocks.
This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

x86: Detect whether we should use Xen SWIOTLB.

It is paramount that we call pci_xen_swiotlb_detect before
pci_swiotlb_detect as both implementations use the 'swiotlb'
and 'swiotlb_force' flags. The pci-xen_swiotlb_detect inhibits
the swiotlb_force and swiotlb flag so that the native SWIOTLB
implementation is not enabled when running under Xen.

We add the glue code that sets up a dma_ops structure with the
xen_swiotlb_* functions. The code turns on xen_swiotlb flag
when it detects it is running under Xen and it is either
in privileged mode or the iommu=soft flag was passed in.
It also disables the bare-metal SWIOTLB if the Xen-SWIOTLB has
been enabled.
Note: The Xen-SWIOTLB is only built when CONFIG_XEN is enabled.

Rather than trying to deal with aliases once they appear, just completely
inhibit them. Mostly the removal of aliases was managable, but it comes
unstuck in xen_create_contiguous_region() because it gets executed at
interrupt time (as a result of dma_alloc_coherent()), which causes all
sorts of confusion in the vmap code, as it was never intended to be run
in interrupt context.
This has the unfortunate side effect of removing all the unmap batching
the vmap code so carefully added, but that can't be helped.

A memory region must be physically contiguous in order to be accessed
through DMA. This patch adds xen_create_contiguous_region, which
ensures a region of contiguous virtual memory is also physically
contiguous.
Based on Stephen Tweedie's port of the 2.6.18-xen version.
Remove contiguous_bitmap[] as it's no longer needed.

PV DomU domains are allowed to map hardware MFNs for PCI passthrough,
but are not generally allowed to map raw machine pages. In particular,
various pieces of code try to map DMI and ACPI tables in the ISA ROM
range. We disallow _PAGE_IOMAP for those mappings, so that they are
redirected to a set of local zeroed pages we reserve for that purpose.

This patch moves the dependency of watchdog timer driver from MACH_XXX(board)
to ARCH_XXX(SoC). This will enable all machines using Samsung S3C64XX and S5P
SoCs to use the WDT driver by default.

This patch adds HAVE_S3C2410_I2C to control inclusion of I2C bus driver
on Samsung SoCs and makes I2C bus driver dependency SoC specific instead
of machine specific. This will enalbe all machines using Samsung ARCH_S3C2410,
_S3C64XX, _S5P6440, _S5PC100, and _S5PV210 to select the I2C driver by default

On some Samsung SoCs not all SDHCI controllers have card detect (CD)
line. For some embedded designs it is not even needed, because ususally
the device (like SDIO flash memory or wifi controller) is permanently
wired to the controller. There are also systems which have a card detect
line connected to some of the external interrupt lines or the presence
of the card depends on some other actions (like enabling a power
regulator).
This patch adds all required changes to platform support code, so
another patch, which extends the driver with support for the new card
detection methods can be applied.
