- pci_dma_supported() is called after pci_set_dma_mask() which
  already did check that for us. This patch removes the unneeded call to
  pci_dma_supported() at bttv-driver.c

- Ensure a sufficient I2C bus idle time between 2 messages for
  saa7134-i2c.c

- It is important to write at first to MO_GP3_IO for cx88-tvaudio.c

- Use try_to_freeze() instead of refrigerator at msp3400.c

- Recognizing the MFPE05-2 Tuner at tveeprom.c

- Add new parameter to help identify radio chipsets at tuner module:
  show_i2c=1 will show 16 reading bytes from detected tuners.

- BTTV does generate some Unimplemented IOCTL log at tuner module:
  0x40046d11(dir=1,tp=0x6d,nr=17,sz=4) means that it is sending
  MSP3400 calls to non-msp3400 tuners. Warning eliminated.
  VIDIOSAUDIO is also called, so debug messages updated. It is still
  requiring IOCTL implementation.

- Added two more tuners.

- Add support for the SVideo input on the GDI Black Gold.

We know that the randomisation slows down some workloads on Transmeta CPUs
by quite large amounts.  We think it's because the CPU needs to recode the
same x86 instructions when they pop up at a different virtual address after

If there are devices that use interrupts over a suspend event, ACPI must
restore the PCI interrupt links on resume.  Anything else breaks any
device that hasn't been converted to the new (dubious) PM rules.

Drivers that need the irq free/re-aquire sequence can be done one by one
independently of this one.

There's no real guarantee that handle_mm_fault() will always be able to
break a COW situation - if an update from another thread ends up
modifying the page table some way, handle_mm_fault() may end up
requiring us to re-try the operation.

That's normally fine, but get_user_pages() ended up re-trying it as a
read, and thus a write access could in theory end up losing the dirty
bit or be done on a page that had not been properly COW'ed.

This makes get_user_pages() always retry write accesses as write
accesses by making "follow_page()" require that a writable follow has
the dirty bit set.  That simplifies the code and solves the race: if the
COW break fails for some reason, we'll just loop around and try again.

This removes sys_set_zone_reclaim() for now.  While i'm sure Martin is
trying to solve a real problem, we must not hard-code an incomplete and
insufficient approach into a syscall, because syscalls are pretty much
for eternity.  I am quite strongly convinced that this syscall must not
hit v2.6.13 in its current form.

Firstly, the syscall lacks basic syscall design: e.g. it allows the
global setting of VM policy for unprivileged users. (!) [ Imagine an
Oracle installation and a SAP installation on the same NUMA box fighting
over the 'optimal' setting for this flag. What will they do? Will they
try to set the flag to their own preferred value every second or so? ]

Secondly, it was added based on a single datapoint from Martin:

 http://marc.theaimsgroup.com/?l=linux-mm&m=111763597218177&w=2

where Martin characterizes the numbers the following way:

 ' Run-to-run variability for "make -j" is huge, so these numbers aren't
   terribly useful except to see that with reclaim the benchmark still
   finishes in a reasonable amount of time. '

in other words: the fundamental problem has likely not been solved, only
a tendential move into the right direction has been observed, and a
handful of numbers were picked out of a set of hugely variable results,
without showing the variability data. How much variance is there
run-to-run?

I'd really suggest to first walk the walk and see what's needed to get
stable & predictable kernel compilation numbers on that NUMA box, before
adding random syscalls to tune a particular aspect of the VM ... which
approach might not even matter once the whole picture has been analyzed
and understood!

The third, most important point is that the syscall exposes VM tuning
internals in a completely unstructured way. What sense does it make to
have a _GLOBAL_ per-node setting for 'should we go to another node for
reclaim'? If then it might make sense to do this per-app, via numalib or
so.

The change is minimalistic in that it doesnt remove the syscall and the
underlying infrastructure changes, only the user-visible changes.  We
could perhaps add a CAP_SYS_ADMIN-only sysctl for this hack, a'ka
/proc/sys/vm/swappiness, but even that looks quite counterproductive
when the generic approach is that we are trying to reduce the number of
external factors in the VM balance picture.

When you rm a watch, an IN_IGNORED event is sent down the event queue
with the watch descriptor that you just rm'd.

If you then add a watch you could get the ignored watch's wd and if you

newly created watch was just ignored.

SCSI=m must disallow static drivers.

The problem is that all the SATA drivers depend on SCSI_SATA.

With SCSI=m and SCSI_SATA=y this allows the static enabling of the SATA
drivers with unwanted effects, e.g.:
- SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y
  -> SCSI_ATA_ADMA is built statically but scsi/built-in.o is not linked
     into the kernel
- SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y, SCSI_SATA_AHCI=m
  -> SCSI_ATA_ADMA and libata are built statically but
     scsi/built-in.o is not linked into the kernel,
     SCSI_SATA_AHCI is built modular (unresolved symbols due to missing
                                      libata)
