Add a debug check for workqueues nested more than three deep via the
direct-run-workqueue() path.

Because keventd is a resource which is shared between unrelated parts of the
kernel it is possible for one person's workqueue handler to accidentally call
another person's flush_scheduled_work().  thockin managed it by calling
mntput() from a workqueue handler.  It deadlocks.

It's simple enough to fix: teach flush_scheduled_work() to go direct when it
discovers that the calling thread is the one which should be running the
work.

Note that this can cause recursion.  The depth of that recursion is equal to
the number of currently-queued works which themselves want to call
flush_scheduled_work().  If this ever exceeds three I'll eat my hat.

This patch fixes a bug in the SELinux compute_av code; the current code
yields the right access computation but can cause unnecessary (but
harmless) processing to occur when transition permission wasn't granted in
the first place by the TE configuration.  Thanks to Chad Hanson of TCS for
reporting the bug.

modpost or to be more specific sumversion.c was not behaving correct when
used with O= and MODULE_VERSION was used.  Previously it failed to use
local .h when calculation the md-sum in case of a O= build.

The following patch introduces the following:

- A generic get_next_line()

- Check that the topmost part of the directory matches

- Using strrch when checking for file with suffix .o

- Use NOFAIL for allocations in sumversion

- Avoid memory leak in new_module

The generic get_next_line will pay off when Andreas implmentation of
storing symbol addresses in a seperate file is introduced.

check_region() fix

From: Willem Riede <wrlk@riede.org>

The patch revises the error handling in ide-scsi, fixing the scheduling
while locked issues, and make it work properly, at least for me...

Specific changes in this patch:

- introduce idescsi_expiry, a timeout routine for the ide subsystem,
  which simply flags the fact that the command timed out, but postpones
  any other action until either the command still finishes on its own
  (unlikely?) or the scsi error handler kicks in;

- introduce idescsi_atapi_error and idescsi_atapi_abort, error routines
  for the ide subsystem, which are modeled after those of ide-cd, but
  take only minimal effort to recover, leaving the heavy lifting for
  the scsi error handler;

- rewrite (and rename for clarity) idescsi_eh_abort and idescsi_eh_error,
  the abort/error routines to be called by the scsi error handler --
  this redesign should not have the scheduling while atomic problems
  of the old implementation.

- move ide_cdrom_dump_status() from ide-cd.c to ide-lib.c as
  ide_dump_atapi_status() and both ide-cd and ide-scsi call it.

- replaces BUG() by WARN_ON()/printk in the error handling code.

- sets TASK_UNINTERRUPTIBLE before schedule_timeout() and moves the host
  unlock/lock around the while loop inside the loop in idescsi_eh_reset().

This patch extends the SELinux policy engine to support conditional policy
logic based on a set of policy booleans, allowing well-formed changes to
the policy to be defined within and mediated by the policy itself.

The conditional policy extensions were implemented and contributed by
Tresys Technology.

Userland packages that support these extensions are already available from
nsa.gov/selinux, and backward compatibility is provided for the prior
policy version.

The patch also includes a small change to enable detection of the optional
MLS policy model on a SELinux system and fixes to the conditional policy
extensions to allow the MLS policy to work correctly with them that were
implemented and contributed by Trusted Computer Solutions.

This patch saves 2MB of memory on a 1GB x86-64 machine, 20MB on a 10GB

  Starting at around 2.6.4-rc2-mm1, I keep seeing 'scripts/fixdep: Text
  file busy' messages when doing a -j10 bzImage build - which seems to
  suggest that by the time fixdep is used by the build system it's not
  built yet.

Sam said:

I was pretty sure it was something I had caused, so I gave it a spin.  What
actually happened was that we tried to build the target 'silentoldconfig'
in parrallel with 'scripts'.  Since 'silentoldconfig' started a new make
and then the config target needed 'scripts' we saw two parallel runs.

The way I decided to fix it was to split scripts/ in two parts.  The first
part is now the very basic stuff - moved to scripts/basic/.  The second
part is dependent on kernel config etc.  and kept in scripts/

In the 2.7 timeframe i will redo this initial stuff - it's becoming too
messy for anyone to understand today.


Description:

Fix dependencies in early phases of kernel build.  This solves a few
problems nively: modpost is no longer rebuild twicewhen reaching the
'target' state 'make -j10' now works nicely again

The patch is rather large due to the following file moves:
mkdir scripts/basic
mv scripts/fixdep.c        scripts/basic
mv scripts/split-include.c scripts/basic
mv scripts/docproc.c       scripts/basic

into ppc970.osdl.org:/home/torvalds/v2.5/linux

The g5 iommu code would fill the "iommu_table" member of whatever
device node was pointed to by pcidev->sysdata during boot. However,
the ppc64 kernel fills that with a pointer to the PHB node which is
later replaced "lazily" with a pointer to the real node when calling
pci_device_to_OF_node(). In this case, we were thus "losign" the
iommu_table pointer. Typical symptom: loss of the SATA when looking
at it's /proc entry.

This fixes it by forcing the update to the final sysdata pointer
when filling up the iommu_table pointers. The "lazy" thing is useless
on pmac anyway.

SN2 platforms provide oemdata in salinfo records.  The decode of that
oemdata is done via prom routines.  This patch provides the interface
from user space through the kernel into the prom to do the oem decode.

Apparently GCC sometimes fails to insert a stop-bit when re-using p14
after the spinlock directives, even though the register is clearly marked
as "clobbered".

Use the proper (and cleaner) probing API instead of the old
scsi_module.c hack, don't use the typedefs I plan to kill in 2.7 and
mark everything static

This Kconfig patch basically just makes ia64 look a little more like i386:
        - moves system type above processor type
        - moves PM & ACPI to a new top-level menu
        - moves PCI/PCMCIA to a new top-level menu

See this ChangeSet:

http://lia64.bkbits.net:8080/linux-ia64-2.4/cset@40524248tkgE0RDYQL0IyiAdFxo_Ew

The MCA code is now slim enough that there isn't much point in keeping
CONFIG_IA64_MCA anymore.

The patch that moved and renamed consistent_dma_mask neglected
to fix up arch/ia64/hp/common/sba_iommu.c.

The last mod to fix the staircase printing - missed some bracing...
