Problem:
A recovery thread must not be active when device is removed.
In qeth_remove_device() an interruptible wait operation is used
to wait until a qeth recovery thread is finished. If a user really
interrupts the ungroup operation of a qeth device while a recovery
is running, cio and qeth are out of sync (device already removed
from cio, but kept in qeth). A following module unload of qeth
results in a kernel OOPS here.
Solution:
Do not allow interruption of ungroup operation to guarantee
finishing of a potentially running qeth recovery thread.

This patch fixes two problems during driver unload. The pci_disable_device()
call is before firmware reload, causing reads and writes across PCI bus after
disabling device. Second problem is the register window was wrong during
firmware reload

Loading firmware during PCI probe can lead to incorrect initialization,

The IOC3 driver's UART detection bits used to rely on the the firmware
setting the UART pre-divider in a way that's apropriate for the 8250
driver which doesn't currently program this register. This happens
to work for the console but not rarely for additional ports.
While at it, also program the UART to RS-232 PIO mode; it the UART might
have been in mac-serial and/or DMA mode though that hasn't actually been
observed in practice.

For hugepage mappings, the file offset, like the address and size, needs to
be aligned to the size of a hugepage.
In commit 68589bc353037f233fe510ad9ff432338c95db66, the check for this was
moved into prepare_hugepage_range() along with the address and size checks.
But since BenH's rework of the get_unmapped_area() paths leading up to
commit 4b1d89290b62bb2db476c94c82cf7442aab440c8, prepare_hugepage_range()
is only called for MAP_FIXED mappings, not for other mappings. This means
we're no longer ever checking for an aligned offset - I've confirmed that
mmap() will (apparently) succeed with a misaligned offset on both powerpc
and i386 at least.
This patch restores the check, removing it from prepare_hugepage_range()
and putting it back into hugetlbfs_file_mmap(). I'm putting it there,
rather than in the get_unmapped_area() path so it only needs to go in one
place, than separately in the half-dozen or so arch-specific
implementations of hugetlb_get_unmapped_area().

We find that SB700 and SB800 use the same SMBus device ID as SB600, which is
0x4385, instead of the already submitted 0x4395.
Besides removing the wrong SB700 device ID, add SB800 support to kernel, by
renaming the PCI_DEVICE_ID_ATI_IXP600_SMBUS into
PCI_DEVICE_ID_ATI_SBX00_SMBUS.

Spotted by taoyue <yue.tao@windriver.com> and Jeremy Katz <jeremy.katz@windriver.com>.
collect_signal: sigqueue_free:
list_del_init(&first->list);
if (!list_empty(&q->list)) {
// not taken
}
q->flags &= ~SIGQUEUE_PREALLOC;
__sigqueue_free(first); __sigqueue_free(q);
Now, __sigqueue_free() is called twice on the same "struct sigqueue" with the
obviously bad implications.
In particular, this double free breaks the array_cache->avail logic, so the
same sigqueue could be "allocated" twice, and the bug can manifest itself via
the "impossible" BUG_ON(!SIGQUEUE_PREALLOC) in sigqueue_free/send_sigqueue.
Hopefully this can explain these mysterious bug-reports, see

This shows that a driver's irq handler was running both in hard interrupt
and process contexts with irqs enabled. The latter was done during
free_irq() call and was possible only with CONFIG_DEBUG_SHIRQ enabled.
This was fixed by another patch.
But similar problem is possible with request_irq(): any locks taken from
irq handler could be vulnerable - especially with soft interrupts. This
patch fixes it by disabling local interrupts during handler's run. (It
seems, disabling softirqs should be enough, but it needs more checking
on possible races or other special cases).

In the function, eCryptfs calls sync_page() method of a lower filesystem
without checking its existence. However, there are many filesystems that
don't have this method including network filesystems such as NFS, AFS, and
so forth. They may fail when an eCryptfs page is waiting for lock.

Update various SPI drivers so they properly support
- coldplug through "modprobe $(cat /sys/devices/.../modalias)"
- hotplug through "modprobe $(MODALIAS)"
The basic rule for platform, SPI, and (new style) I2C drivers is just
to make sure that modprobing the driver name works. In this case, all
the relevant drivers are platform drivers, and this patch either
(a) Changes the driver name, if no in-tree code would break;
this is simpler and thus preferable in the long term.
(b) Adds MODULE_ALIAS directives, when in-tree platforms declare
devices using the current driver name; less desirable.
Most systems will link SPI controller drivers statically, but
there's no point in being needlessly broken.

taskstats.ac_exitcode is assigned to task_struct.exit_code in bacct_add_tsk()
through the following kernel function calls:
do_exit()
taskstats_exit()
fill_pid()
bacct_add_tsk()
The problem is that in do_exit(), task_struct.exit_code is set to 'code' only
after taskstats_exit() has been called. So we need to move the assignment
before taskstats_exit().

This patch corrects sata_promise to classify FastTrack TX4200

source FT TX4200 driver confirms this classification.
Treating it as a first-generation chip causes several problems:
1. Detection failures. This is a recent regression triggered by
the hotplug-enabling changes in 2.6.23-rc1.
2. Various "failed to resume link for reset" warnings.

1) sun4{u,v}_build_msi() have improper return value handling.

2) sun4{u,v}_build_msi() should return -ENOMEM instead of
calling prom_prom() halt with kzalloc() of the interrupt
data fails.
3) We 'remembered' the MSI number using a singleton in the
struct device archdata area, this doesn't work for MSI-X
which can cause multiple MSIs assosciated with one device.
Delete that archdata member, and instead store the MSI
number in the IRQ chip data area.
