adfdebceac update Documentation/driver-model/platform.txt
Make note of the legacy "probe-the-hardware" drivers, and some APIs that
are mostly unused except by such drivers.  We probably can't escape having
legacy drivers for a while (e.g.  old ISA drivers), but we can at least
discourage this style code for new drivers, and unless it's unavoidable.

3ce53fc4c5 [CIFS] CIFS should honour umask
This patch makes CIFS honour a process' umask like other filesystems.
Of course the server is still free to munge the permissions if it wants
to; but the client will send the "right" permissions to begin with.

A few caveats:

1) It only applies to filesystems that have CAP_UNIX (aka support unix
extensions)
2) It applies the correct mode to the follow up CIFSSMBUnixSetPerms()
after remote creation

When mode to CIFS/NTFS ACL mapping is complete we can do the
same thing for that case for servers which do not
support the Unix Extensions.

0d2157f78d ide: HPA detect from resume
Currently when system which have HPA require HPA to be detected and
disabled upon resume from RAM or disk. The current IDE drivers do not do
this nor does libata (obviously it since it doesn't support HPA yet).

I have implemented this into the current IDE drivers and it has been
tested by many others since 7/15/2006 in bug number 6840:

	http://bugzilla.kernel.org/show_bug.cgi?id=6840

0380dad45e it821x: RAID mode fixes
The DMA support for RAID mode broke after:

	commit 71ef51cc17

	Author: Jens Axboe <axboe@suse.de>
	Date:   Fri Jul 28 08:58:26 2006 +0200

	    [PATCH] ide: if the id fields looks screwy, disable DMA

	    It's the safer choice. Originally due to a bug in itx821x, but a
	    generally sound thing to do.

	    Signed-off-by: Jens Axboe <axboe@suse.de>

However it worked by pure luck before Jens' fixes: bogus ide_dma_enable()
usage in it821x driver combined with loosy check in ide_dma_verbose() allowed
the hardware to operate in DMA mode.  When these problems were fixed the DMA
support broke...

The source root for the regression turned out to be that the it821x.c code
was clearing too much of id->field_valid.  The IDE core code was using the
original value of id->field_valid to do the tuning but later DMA got disabled
in ide_dma_verbose() because of the incorrect id->field_valid fixup.  Fix it.

While at it:

* Do fixup() after probing the drives but before tuning them (which is also
  OK w.r.t. ide_undecoded_slave() fixup).  This change fixes device IDENTIFY
  data to be consistent before/after the tuning and allows us to remove extra
  re-tuning of drives from it821x_fixups().

* Fake MWDMA0 enabled/supported bits in IDENTIFY data if the device has
  DMA capable bit set (this is just to tell the IDE core that DMA is
  supported since it821x firmware takes care of DMA mode programming).

* Don't touch timing registers and don't program transfer modes on devices
  et all when in RAID mode - depend solely on firmware to do the tuning
  (as suggested by Alan Cox and done in libata pata_it821x driver).

Thanks for testing the patch goes out to Thomas Kuther.

1abb8a8b84 serverworks: fix CSB6 tuning logic
Problem noticed by Joe Zbiciak, see

	http://kerneltrap.org/node/8252

for details.

On CSB6 the driver is using BIOS settings and not programming DMA/PIO timings
itself.  However the logic was completely broken and resulted in wrong timings
being silently allowed (instead of being corrected by the driver).

This bug would explain some data corruption/timeout issues with Serverworks
MegaIDE in RAID mode that Alan Cox has fixed recently with:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2074a106f52b6371885afbd714e929d60d0e3f64

For 2.6.23 we may be better off with completely switching the driver to always
programming timings (libata pata_serverworks.c driver is doing things this way
and there were no problems reported so far) but for 2.6.22 lets fix the bug
in the simplest and the least intrusive way.

72fb39ea58 V4L/DVB (5761): Fix broken b2c2 dependency on non x86 architectures
This patch moves flexcop-dma (currently used only by flexcop-pci) to
b2c2-flexcop-pci module, that is dependent on CONFIG_PCI, fixing the bug 
as reported by Geert Uytterhoeven <geert@linux-m68k.org>:

drivers/media/dvb/b2c2/flexcop-dma.c uses the PCI DMA API, but
DVB_B2C2_FLEXCOP doesn't depend on PCI, causing the following problem on
PCI-less systems:

| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'
| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'

DVB_B2C2_FLEXCOP_PCI and DVB_B2C2_FLEXCOP_USB.

Sliced VBI transfers use PIO instead of DMA. This was done inside the

a lot of time was spent inside the interrupt handler. All PIO copies are

624fc7f52b V4L/DVB (5700): Saa7111: fix picture settings cache bug
If the SAA7111 device is powered down, and requires re-initialisation when
the V4L device is opened (as on the NetWinder), the SAA7111 driver gets
completely confused about the current settings.

The problem is centred around the way the driver keeps _two_ cached copies
of the current settings - one of the struct video_picture settings, and one
of the registers.

When the decoder is re-initailised, the cached register settings are
overwritten, as are the values in the hardware registers.  However, the
cached video_picture settings are not.

Resolve this by removing the useless and buggy second level of caching for
video_picture.  Instead, provide a function which updates register values
if and only if the value we are going to write to the register has changed.

620a324b74 splice: __generic_file_splice_read: fix read/truncate race
Original patch and description from Neil Brown <neilb@suse.de>,
merged and adapted to splice branch by me. Neils text follows:

__generic_file_splice_read() currently samples the i_size at the start
and doesn't do so again unless it needs to call ->readpage to load
a page.  After ->readpage it has to re-sample i_size as a truncate
may have caused that page to be filled with zeros, and the read()
call should not see these.

However there are other activities that might cause ->readpage to be
called on a page between the time that __generic_file_splice_read()
samples i_size and when it finds that it has an uptodate page. These
include at least read-ahead and possibly another thread performing a
read

So we must sample i_size *after* it has an uptodate page.  Thus the
current sampling at the start and after a read can be replaced with a
sampling before page addition into spd.

8c2786cfa6 [SPARC64]: Handle PCI bridges without 'ranges' property.
This fixes the IDE controller not showing up on Netra-T1
systems.

Just like Simba bridges, some PCI bridges can lack the
'ranges' OBP property.  So we handle this similarly to
the existing Simba code:

1) In of_device register address resolving, we push the
   translation to the parent.

2) In PCI device scanning, we interrogate the PCI config
   space registers of the PCI bus device in order to resolve
   the resources, just like the generic Linux PCI probing
   code does.

With much help and testing from Fabio, who also reported
the initial problem.

e5e3c84b70 enable interrupts in user path of page fault.
This is a minor fix, but what is currently there is essentially wrong.
In do_page_fault, if the faulting address from user code happens to be
in kernel address space (int *p = (int*)-1; p = 0xbed;)  then the
do_page_fault handler will jump over the local_irq_enable with the

  goto bad_area_nosemaphore;

But the first line there sees this is user code and goes through the
process of sending a signal to send SIGSEGV to the user task. This whole
time interrupts are disabled and the task can not be preempted by a
higher priority task.

This patch always enables interrupts in the user path of the
bad_area_nosemaphore.

ec4d18f219 [SPARC64]: Fix SBUS IRQ regression caused by PCI-E driver.
We used to access the 64-bit IRQ IMAP and ICLR registers of bus
controllers 4-bytes in and as a 32-bit register word, since only the
low 32-bits were relevant.  This seemed like a good idea at the time.

But the PCI-E controller requires full 8-byte 64-bit access to
these registers, so we switched over to accessing them fully.

SBUS was not adjusted properly, which broke interrupts completely.

321566c250 [SPARC64]: Fix 2 bugs in PCI Sabre bus scanning.
If we are on hummingbird, bus runs at 66MHZ.

pbm->pci_bus should be setup with the result of pci_scan_one_pbm()
or else we deref NULL pointers in the error interrupt handlers.

4aa2e62c45 xfrm: Add security check before flushing SAD/SPD
Currently we check for permission before deleting entries from SAD and
SPD, (see security_xfrm_policy_delete() security_xfrm_state_delete())
However we are not checking for authorization when flushing the SPD and
the SAD completely. It was perhaps missed in the original security hooks
patch.

This patch adds a security check when flushing entries from the SAD and
SPD.  It runs the entire database and checks each entry for a denial.
If the process attempting the flush is unable to remove all of the
entries a denial is logged the the flush function returns an error
without removing anything.

This is particularly useful when a process may need to create or delete
its own xfrm entries used for things like labeled networking but that
same process should not be able to delete other entries or flush the
entire database.
