mmc: atmel-mci: Add support for SDIO interrupts

Atmel-mci support for SDIO interrupts.  This adds the enable_sdio_irq()
function and the configuration of sdio irq mask per slot.  With this irq
mask information, we keep the idea of multiple slot per sd/mmc host (not
only A and B).  MMC_CAP_SDIO_IRQ is added according to slot configuration.

A new little function is added to run mmc_signal_sdio_irq() during
interrupt handling routine.

mmc-omap: add support for 16-bit and 32-bit registers

The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring
a modification of the register addresses in the mmc-omap driver.  To
resolve this, a bit shift is performed on base register addresses, either
by 1 or 2 bits depending on the CPU in use.  This yields the correct
registers for each CPU.

davinci: mmc: pass number of SG segments as platform data

On some platforms like DM355, the number of EDMA parameter slots available
for EDMA_SLOT_ANY usage are few.  In such cases, if MMC/SD uses 16 slots
for each instance of MMC controller, then the number of slots available
for other modules will be very few.

By passing the number of EDMA slots to be used in MMC driver from platform
data, EDMA slots available for other purposes can be controlled.

Most of the platforms will not use this platform data variable.  But on
DM355, as the number of EDMA resources available is limited, the number of
scatter- gather segments used inside the MMC driver can be 8 (passed as
platform data) instead of 16.  On DM355, when the number of scatter-gather
segments was reduced to 8, I saw a performance difference of about
0.25-0.4 Mbytes/sec during write.  Read performance variations were
negligible.

I/O errors can happen due to temporary failures, like multipath
errors or losing network contact with the iSCSI server. Because
of that, the VM will retry readpage on the page.

However, do_generic_file_read does not clear PG_error.  This
causes the system to be unable to actually use the data in the

successfully!

The function filemap_fault has had a ClearPageError before
readpage forever.  This patch simply adds the same to
do_generic_file_read.

alpha: invoke oom-killer from page fault

As explained in commit 1c0fe6e3bd, we want to call the architecture
independent oom killer when getting an unexplained OOM from
handle_mm_fault, rather than simply killing current.

Convert alpha to use clocksources instead of arch_gettimeoffset

Alpha has a tsc like rpcc counter that it uses to manage time.
This can be converted to an actual clocksource instead of utilizing
the arch_gettimeoffset method that is really only there for legacy
systems with no continuous counter.

Further cleanups could be made if alpha converted to the clockevent
model.

driver core: add devname module aliases to allow module on-demand auto-loading

This adds:
  alias: devname:<name>
to some common kernel modules, which will allow the on-demand loading
of the kernel module when the device node is accessed.

Ideally all these modules would be compiled-in, but distros seems too
much in love with their modularization that we need to cover the common
cases with this new facility. It will allow us to remove a bunch of pretty
useless init scripts and modprobes from init scripts.

The static device node aliases will be carried in the module itself. The
program depmod will extract this information to a file in the module directory:
  $ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname
  # Device nodes to trigger on-demand module loading.
  microcode cpu/microcode c10:184
  fuse fuse c10:229
  ppp_generic ppp c108:0
  tun net/tun c10:200
  dm_mod mapper/control c10:235

Udev will pick up the depmod created file on startup and create all the
static device nodes which the kernel modules specify, so that these modules
get automatically loaded when the device node is accessed:
  $ /sbin/udevd --debug
  ...
  static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184
  static_dev_create_from_modules: mknod '/dev/fuse' c10:229
  static_dev_create_from_modules: mknod '/dev/ppp' c108:0
  static_dev_create_from_modules: mknod '/dev/net/tun' c10:200
  static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235
  udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666
  udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666

A few device nodes are switched to statically allocated numbers, to allow
the static nodes to work. This might also useful for systems which still run
a plain static /dev, which is completely unsafe to use with any dynamic minor
numbers.

Note:
The devname aliases must be limited to the *common* and *single*instance*
device nodes, like the misc devices, and never be used for conceptually limited
systems like the loop devices, which should rather get fixed properly and get a
control node for losetup to talk to, instead of creating a random number of
device nodes in advance, regardless if they are ever used.

This facility is to hide the mess distros are creating with too modualized
kernels, and just to hide that these modules are not compiled-in, and not to
paper-over broken concepts. Thanks! :)

ALSA: pcm: fix delta calculation at boundary wraparound

In the cleanup of the hw_ptr update functions in 2.6.33, the calculation
of the delta value was changed to use the modulo operator to protect
against a negative difference due to the pointer wrapping around at the
boundary.

However, the ptr variables are unsigned, so a negative difference would
result in the two complement's value which has no relation to the actual
difference relative to the boundary; the result is typically some value
near LONG_MAX-boundary.  Furthermore, even if the modulo operation would
be done with signed types, the result of a negative dividend could be
negative.

The invalid delta value is then caught by the following checks, but this
means that the pointer update is ignored.

To fix this, use a range check as in the other pointer calculations.

PowerPC platform.

It is possible that page_mkclean() is invoked in the deferred io work
function _before_ a PTE has been marked dirty.  In this case, the page is
removed from the defio pagelist but page_mkclean() does not write-protect
the page again.  The end result is that defio ignores all subsequent
writes to the page and the corresponding portions of the framebuffer never
get updated.

The fix consists in keeping track of the pages with non-dirty PTEs,
re-checking them again on the next deferred io work iteration.  Note that
those pages are not passed to the defio callback as they are not written

fbdev: da8xx/omap-l1xx: implement double buffering

This work includes the following:

- Implement handler for FBIO_WAITFORVSYNC ioctl.

- Allocate the data and palette buffers separately.  A consequence of
  this is that the palette and data loading is now done in different
  phases.  And that the LCD must be disabled temporarily after the palette
  is loaded but this will only happen once after init and each time the
  palette is changed.  I think this is OK.

- Allocate two (ping and pong) framebuffers from memory.

- Add pan_display handler which toggles the LCDC DMA registers between
  the ping and pong buffers.

rtc-cmos: do dev_set_drvdata() earlier in the initialization

The bug is an oops when dev_get_drvdata() returned null in
cmos_update_irq_enable().  The call tree looks like this:
  rtc_dev_ioctl()
    => rtc_update_irq_enable()
      => cmos_update_irq_enable()

It's caused by a race condition in the module initialization.  It is
rtc_device_register() which makes the ioctl operations live so I moved
the call to dev_set_drvdata() before the call to rtc_device_register().

lis3: separate configuration function for 8 bit device

Separate configuration function for 8 bit version of the chip.  This way
generic part of the init function stays little bit more readable.

crc32: use __BYTE_ORDER macro for endian detection.

Since crc32.c contains a nifty test program that can be executed in user
space, make sure endian detection works reliably in user space too.

crc32: major optimization

Precompute more crc32 values(0xcc00, 0xcc0000 and 0xcc000000) into tables.
 This increases the table size from 1KB to 4KB but the performance benfit
makes it worth it:

28% faster on MPC8321, 266 MHz
2x faster on Core 2 Duo, 3.1GHz

checkpatch: warn on declaration with storage class not at the beginning

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

checkpatch: add check for too short Kconfig descriptions

I've seen various new Kconfigs with rather unhelpful one liner
descriptions.  Add a Kconfig warning for a minimum length of the Kconfig
help section.

Right now I arbitarily chose 4. The exact value can be debated.
