9a2816c1c4 V4L/DVB (5014): Allyesconfig build fixes on some non x86 arch
- CAFE_CCIC needs to depend on PCI, else "allyesconfig" breaks
   on systems without PCI
- em28xx-video can't udelay(2500) else "allyesconfig" breaks
   on systems that refuse to spin that long (I saw it on ARM)

b331def2d3 V4L/DVB (4982): Fix broken audio mode handling for line-in in msp3400.
The wrong matrix was used when an external input was selected instead of
the tuner input. The rxsubchans field was also not initialized to STEREO
for an external input. And finally the msp34xxg_detect_stereo() should
not try to detect stereo for an external input, that code is for the
tuner input only.
Together these bugs made it hit 'n miss whether you ever got stereo out
of the msp3400 for an external input.

0888f06ac9 [PATCH] sched: fix bad missed wakeups in the i386, x86_64, ia64, ACPI and APM idle code
Fernando Lopez-Lezcano reported frequent scheduling latencies and audio
xruns starting at the 2.6.18-rt kernel, and those problems persisted all
until current -rt kernels. The latencies were serious and unjustified by
system load, often in the milliseconds range.

After a patient and heroic multi-month effort of Fernando, where he
tested dozens of kernels, tried various configs, boot options,
test-patches of mine and provided latency traces of those incidents, the
following 'smoking gun' trace was captured by him:

                 _------=> CPU#
                / _-----=> irqs-off
               | / _----=> need-resched

   <...>-5856  0D..1  619us : trace_stop_sched_switched <<...>-5856> (37 0)

what is visible in this trace is that CPU#1 ran try_to_wake_up() for
PID:5856, it placed PID:5856 on CPU#0's runqueue and ran resched_task()
for CPU#0. But it decided to not send an IPI that no CPU - due to
TS_POLLING. But CPU#0 never woke up after its NEED_RESCHED bit was set,
and only rescheduled to PID:5856 upon the next lapic timer IRQ. The
result was a 600+ usecs latency and a missed wakeup!

the bug turned out to be an idle-wakeup bug introduced into the mainline
kernel this summer via an optimization in the x86_64 tree:

    commit 495ab9c045
    Author: Andi Kleen <ak@suse.de>
    Date:   Mon Jun 26 13:59:11 2006 +0200

    [PATCH] i386/x86-64/ia64: Move polling flag into thread_info_status

    During some profiling I noticed that default_idle causes a lot of
    memory traffic. I think that is caused by the atomic operations
    to clear/set the polling flag in thread_info. There is actually
    no reason to make this atomic - only the idle thread does it
    to itself, other CPUs only read it. So I moved it into ti->status.

the problem is this type of change:

        if (!hlt_counter && boot_cpu_data.hlt_works_ok) {
-               clear_thread_flag(TIF_POLLING_NRFLAG);
+               current_thread_info()->status &= ~TS_POLLING;
                smp_mb__after_clear_bit();
                while (!need_resched()) {
                        local_irq_disable();

this changes clear_thread_flag() to an explicit clearing of TS_POLLING.
clear_thread_flag() is defined as:

        clear_bit(flag, &ti->flags);

and clear_bit() is a LOCK-ed atomic instruction on all x86 platforms:

  static inline void clear_bit(int nr, volatile unsigned long * addr)
  {
          __asm__ __volatile__( LOCK_PREFIX
                  "btrl %1,%0"

hence smp_mb__after_clear_bit() is defined as a simple compile barrier:

  #define smp_mb__after_clear_bit()       barrier()

but the explicit TS_POLLING clearing introduced by the patch:

+               current_thread_info()->status &= ~TS_POLLING;

is not an atomic op! So the clearing of the TS_POLLING bit is freely
reorderable with the reading of the NEED_RESCHED bit - and both now
reside in different memory addresses.

CPU idle wakeup very much depends on ordered memory ops, the clearing of
the TS_POLLING flag must always be done before we test need_resched()
and hit the idle instruction(s). [Symmetrically, the wakeup code needs
to set NEED_RESCHED before it tests the TS_POLLING flag, so memory
ordering is paramount.]

Fernando's dual-core Athlon64 system has a sufficiently advanced memory
ordering model so that it triggered this scenario very often.

( And it also turned out that the reason why these latencies never
  triggered on my testsystems is that i routinely use idle=poll, which
  was the only idle variant not affected by this bug. )

The fix is to change the smp_mb__after_clear_bit() to an smp_mb(), to
act as an absolute barrier between the TS_POLLING write and the
NEED_RESCHED read. This affects almost all idling methods (default,
ACPI, APM), on all 3 x86 architectures: i386, x86_64, ia64.

  started.

- all '\n' not to be present at the end of words written to
  sysfs files

- when we use SET_ARRAY_INFO to set the md metadata version,
  set the flag to say that there is persistant metadata.

- allow GET_BITMAP_FILE to be called on an array that hasn't
  been started yet.

fe0e5c4d94 [PATCH] increase CARDBUS_MEM_SIZE
Linus sayeth:

Google knows everything, and finds, on MS own site no less:

  "Windows 2000 default resources:

   One 4K memory window

   One 2 MB memory window

   Two 256-byte I/O windows"

which is clearly utterly bogus and insufficient. But Microsoft apparently
realized this, and:

  "Windows XP default resources:

   Because one memory window of 4K and one window of 2 MB are not
   sufficient for CardBus controllers in many configurations, Windows XP
   allocates larger memory windows to CardBus controllers where possible.
   However, resource windows are static (that is, the operating system
   does not dynamically allocate larger memory windows if new devices
   appear.) Under Windows XP, CardBus controllers will be assigned the
   following resources:

   One 4K memory window, as in Windows 2000

   64 MB memory, if that amount of memory is available. If 64 MB is not
   available the controller will receive 32 MB; if 32 MB is not available,
   the controller will receive 16 MB; if 16 MB is not available, the
   bridge will receive 8 MB; and so on down to a minimum assignment of 1
   MB in configurations where memory is too constrained for the operating
   system to provide a larger window.

   Two 256-byte I/O windows"

So I think we have our answer. Windows uses one 4k window, and one 64MB
window. And they are no more dynamic than we are (we _could_ try to do it
dynamically, but let's face it, it's fairly painful to dynamically expand
PCI bus resources - you may need to reprogram everything up to the root,
so it would be absolutely crazy to do that unless you have some serious
masochistic tendencies).

So let's just increase our default value to 64M too.

31fccf7fe4 [PATCH] gxt4500: Fix colormap and PLL setting, support GXT6000P
This fixes some bugs in the gxt4500 framebuffer driver, and adds support
for GXT6000P cards.

First, I had the red and blue channels swapped in the colormap update code,
resulting in penguins' noses and feet turning blue (though the penguins
weren't actually shivering :).

Secondly, the code that calculated the values to put in the PLL that
generates the pixel clock wasn't observing some constraints that I wasn't
originally aware of, but am now that I have some documentation on the chip.

The GXT6000P is essentially identical from software's point of view, except
for a different reference clock for the PLL, and the addition of a geometry
engine (which this driver doesn't use).

19900cdee2 [PATCH] fix aoe without scatter-gather [Bug 7662]
Fix a bug that only appears when AoE goes over a network card that does not
support scatter-gather.  The headers in the linear part of the skb appeared
to be larger than they really were, resulting in data that was offset by 24
bytes.

This patch eliminates the offset data on cards that don't support
scatter-gather or have had scatter-gather turned off.  There remains an
unrelated issue that I'll address in a separate email.

Fixes bugzilla #7662

bf591b24d0 [PATCH] KVM: Do not export unsupported msrs to userspace
Some msrs, such as MSR_STAR, are not available on all processors.  Exporting
them causes qemu to try to fetch them, which will fail.

So, check all msrs for validity at module load time.
