omap_hsmmc: improve interrupt synchronisation
The following changes were needed:
- do not use in_interrupt() because it will not work
with threaded interrupts
In addition, the following improvements were made:
- ensure DMA is unmapped only after the final DMA interrupt
- ensure a request is completed only after the final DMA interrupt
- disable controller interrupts when a request is not in progress
- remove the spin-lock protecting the start of a new request from
an unexpected interrupt because the locking was complicated and
a 'req_in_progress' flag suffices (since the spin-lock only defers
the unexpected interrupts anyway)
- instead use the spin-lock to protect the MMC interrupt handler
from the DMA interrupt handler
- remove the semaphore preventing DMA from being started while
the previous DMA is still in progress - the other changes make that
impossible, so it is now a BUG_ON condition
- ensure the controller interrupt status is clear before exiting
the interrrupt handler

bugs so backporting is not necessary.

Dropping the module lock and re-taking it deep in the call-chain is
definitely not the right thing to do. That just turns the mutex from a

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.

fb_defio: fix for non-dirty ptes
Fix a problem observed while using fb_defio with a short delay on a
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
by userspace yet.
