s1d13xxxfb_remove() is referenced from s1d13xxxfb_probe(), which is marked
__devinit().  So s1d13xxxfb_remove() cannot be marked __devexit.

Does this all make sense?  Clearly the __devexit section will still be in
core when the __devinit code is run, if the driver was loaded as a module.

But I suppose that if the driver is statically linked, the __devexit section
might be dropped early in boot.  Still, we wouldn't drop __devexit prior to
initcall completion, at which point the __devinit code has all been run
anyway.

verdict: this code was legal and made sense.  Is this a generic problem, or an
arm-specific problem?

The current isofs treatment of hidden files is flawed in two ways.  First,
it does not provide sufficient granularity; it hides both 'hidden' files
and 'associated' files (resource fork for Mac files).  Second, the default
behavior to completely strip hidden files, while an admirable
implementation of the spec, is a poor choice given the real world use of
hidden files as a poor mans copy protection scheme for MSDOS and Windows
based systems.  A longer description of this is available here:

   http://www.uwsg.iu.edu/hypermail/linux/kernel/0205.3/0267.html

This patch was originally built after a few private conversations with Alan
Cox; I shamefully failed to persist in seeing it go forward, I hope to make
amends now.

This patch introduces granularity by allowing explicit control for both
hidden and associated files.  It also reverses the default so that by
default, hidden files are treated as regular files on the iso9660 file
system.

This allow Wine to process Windows CDs, including those that are hybrid
Mac/Windows CDs properly and completely, without our having to go muck up
peoples fstabs as we do now.  (I have tested this with such a hybrid +
hidden CD and have verified that this patch works as claimed).

The bug in rock.c is that it's totally trusting of the contents of the
directories.  If the directory says there's a continuation 10000 bytes into
this 4k block then we cheerily poke around in memory we don't own and oops.

So change rock_continue() to apply various sanity checks, at least ensuring
that the offset+length remain within the bounds for the header part of a
struct rock_ridge directory entry.

Note that the kernel can still overindex the buffer due to the variable size
of the rock-ridge directory entries.  We cannot check that in rock_continue()
unless we go parse the directory entry's signature and work out its size.

For browsable autofs maps, a mount request that arrives at the same time an
expire is happening can fail to perform the needed mount.

This happens becuase the directory exists and so the revalidate succeeds when
we need it to fail so that lookup is called on the same dentry to do the
mount.  Instead lookup is called on the next path component which should be
whithin the mount, but the parent isn't mounted.

The solution is to allow the revalidate to continue and perform the mount as
no directory creation (at mount time) is needed for browsable mount entries.

At the tail end of an expire it's possible for a process to enter
autofs4_wait, with a waitq type of NFY_NONE but find that the expire is
finished.  In this cause autofs4_wait will try to create a new wait but not
notify the daemon leading to a hang.  As the wait type is meant to delay mount
requests from revalidate or lookup during an expire and the expire is done all
we need to do is check if the dentry is a mountpoint.  If it's not then we're
done.

This patch rewrites the handling of remote control events.  Rather than making
them available from a special file in the ibmasmfs, now the events from the
RSA card get translated into kernel input events and injected into the input
subsystem.  The driver now will generate two /dev/input/eventX nodes -- one
for the keyboard and one for the mouse.  The mouse node generates absolute
events more like a touch pad than a mouse.

First of a series of patches for the ibmasm driver.  (that is the driver for

To summarize what they do:

[1] change a #define for the buffer size for commands

[2] Fix a bug where threads in the event handling code calling
    wait_event_interruptible() weren't woken up as expected.

[3] Redesigned how remote mouse and keyboard events received by the driver
    are handled.

[4] Fixed a race in the command reference counting logic.

The kernel takes a very long time to boot if the memory size is bigger then
32767 MB.  The memory size is contained in a structure created by an sclp
call.  The kernel accesses the field with a LH instrution which performs a
sign extension of a 16 bit word.  In the case of a memory size with bit 2^15
set this results in a very large value and the memory detection just loops for
a long time.  In addition if more then 64 GB are used on a 64 bit system the
memory size is read from an incorrect storage location.

Use zero-extention to read the 16 bit memory size and the correct offset to
read the 4 byte memory size on 64 bit.

To make sure switcheroo() can execute when we remap all the executable
image, we used a trick to make it use a local copy of errno...  this trick
does not work with NPTL glibc, only with LinuxThreads, so use another
(simpler) one to make it work anyway.

Hopefully, a lot improved thanks to merging with the version of Al Viro
(which had his part of problems, though, i.e.  removing a fix to another
bug and not fixing the problem on i386).

With Chris Wedgwood <cw@f00f.org>

Currently UML must explicitly call the UML-specific
free_irq_by_irq_and_dev() for each free_irq call it's done.

This is needed because ->shutdown and/or ->disable are only called when the
last "action" for that irq is removed.

Instead, for UML shared IRQs (UML IRQs are very often, if not always,
shared), for each dev_id some setup is done, which must be cleared on the
release of that fd.  For instance, for each open console a new instance
(i.e.  new dev_id) of the same IRQ is requested().

Exactly, a fd is stored in an array (pollfds), which is after read by a
host thread and passed to poll().  Each event registered by poll() triggers
an interrupt.  So, for each free_irq() we must remove the corresponding
host fd from the table, which we do via this -release() method.

In this patch we add an appropriate hook for this, and remove all uses of
it by pointing the hook to the said procedure; this is safe to do since the
said procedure.

Also some cosmetic improvements are included.

This is heavily based on some work by Chris Wedgwood, which however didn't
get the patch merged for something I'd call a "misunderstanding" (the need
for this patch wasn't cleanly explained, thus adding the generic hook was
felt as undesirable).
