This is the cause of the DMA faults and disk corruption that people have
been seeing. Some chipsets neglect to report the RWBF "capability" --
the flag which says that we need to flush the chipset write-buffer when
changing the DMA page tables, to ensure that the change is visible to
the IOMMU.
Override that bit on the affected chipsets, and everything is happy
again.
Thanks to Chris and Bhavesh and others for helping to debug.

Getting this wrong caused
WARNING: at fs/namespace.c:636 mntput_no_expire+0xac/0xf2()
due to optimistically checking cpu_writer->mnt outside the spinlock.
Here's what we really want:
* we know that nobody will set cpu_writer->mnt to mnt from now on
* all changes to that sucker are done under cpu_writer->lock
* we want the laziest equivalent of
spin_lock(&cpu_writer->lock);
if (likely(cpu_writer->mnt != mnt)) {
spin_unlock(&cpu_writer->lock);
continue;
}
/* do stuff */
that would make sure we won't miss earlier setting of ->mnt done by
another CPU.
Anyway, for now we just move the spin_lock() earlier and move the test
into the properly locked region.

Damien Wyart reported high ksoftirqd CPU usage (20%) on an

Shows rcu_check_callbacks() being invoked way too often. It should be called
once per jiffy, and here it is called no less than 22 times in about
3.5 milliseconds, meaning one call every 160 microseconds or so.
Why do we need to call rcu_pending() and rcu_check_callbacks() from the
idle loop of 32-bit x86, especially given that no other architecture does
this?
The following patch removes the call to rcu_pending() and
rcu_check_callbacks() from the x86 32-bit idle loop in order to
reduce the softirq load on idle systems.

Impact: Cleanup; fix inappropriate macro use
ISA addresses on x86 are mapped 1:1 with the physical address space.
Since the ISA address space is only 24 bits (32 for VLB or LPC) it
will always fit in an unsigned int, and at least in the aha1542 driver
using a wider type would cause an undesirable promotion. Hence
explicitly cast the ISA bus addresses to unsigned int.

If the F71882FG chip is at address 0x4e, then the probe at 0x2e will
fail with the following message in the logs:
f71882fg: Not a Fintek device
This is misleading because there is a Fintek device, just at a
different address. So I propose to degrade this message to a debug
message.

When the function graph tracer is activated, it iterates over the task_list
to allocate a stack to store the return addresses.
But the per cpu idle tasks are not iterated by using
do_each_thread / while_each_thread.
So we have to iterate on them manually.
This fixes somes weirdness in the traces and many losses of traces.

arch/x86/kernel/ is getting a bit crowded, and the APIC
drivers are scattered into various different files.
Move them to arch/x86/kernel/apic/*, and also remove
the 'gen' prefix from those which had it.
Also move APIC related functionality: the IO-APIC driver,
the NMI and the IPI code.

Impact: cleanup
In the subarch times there were a number of externs between
various bits of the ES7000 code. Now that there's a single

the functions can be changed the statics.
Beyond the cleanup factor, this also shrinks the size of the

The video_ioctl2 conversion of ivtv in kernel 2.6.27 introduced a bug
causing decoder commands to crash. The decoder commands should have been
handled from the video_ioctl2 default handler, ensuring correct mapping
of the argument between user and kernel space. Unfortunately they ended
up before the video_ioctl2 call, causing random crashes.

This change set is wrong. The affected functions cannot be called from

Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc)
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01
This happens due to a hack at TUV1236D analog setup, where it replaces
tuner address, at 0x61 for 0x0a, in order to save a few memory bytes.
The code assumes that nobody else would try to access the tuner during
that setup, but the point is that there's no lock to protect such
access. So, this opens the possibility of race conditions to happen.
Instead of hacking tuner address, this patch uses a temporary var with
the proper tuner value to be used during the setup. This should save
the issue, although we should consider to write some analog/digital
lock at saa7134 driver.

The devices handled by hid-tmff and hid-zpff were added in the
hid_ignore_list[] instead of hid_blacklist[] in hid-core.c, thus
disabling them completely.
hid_ignore_list[] causes hid layer to skip the device, while
hid_blacklist[] indicates there is a specific driver in hid bus.
Re-enable the devices by moving them to the correct list.

For quite some time users with various UPSes from Powercom were forced to play
magic with bind/unbind in /sys in order to be able to see the UPSes. The
beasts does not work as HID devices, even if claims to do so. cypress_m8
driver works with the devices instead, creating a normal serial port with which
normal UPS controlling software works.
The manufacturer confirmed the upcoming models with proper HID support will
have different device IDs. In any way, it's wrong to have two completely
different modules for one device in kernel.
Blacklist the device in HID (add it to hid_ignore_list) to stop this mess,
finally.

- make oprofile build
- select X86_X2APIC from X86_UV - it relies on it
- export genapic for oprofile modular build

It turns out that LRW has never worked properly on big endian.
This was never discussed because nobody actually used it that
way. In fact, it was only discovered when Geert Uytterhoeven
loaded it through tcrypt which failed the test on it.
The fix is straightforward, on big endian the to find the nth
bit we should be grouping them by words instead of bytes. So
setbit128_bbe should xor with 128 - BITS_PER_LONG instead of
128 - BITS_PER_BYTE == 0x78.
