Make the ACPI /proc/acpi/wakeup interface set the appropriate wake-up bits
of physical devices corresponding to the ACPI devices and make those bits
be set initially for devices that are enabled to wake up by default. This
is needed to restore the 2.6.26 and earlier behavior for the PCI devices
that were previously handled correctly with the help of the
/proc/acpi/wakeup interface.

Check the return value of led_classdev_register and unregister all
registered devices, if registering one device fails. Also the dynamic
memory handling is totally bogus. You can't allocate multiple chunks via
kzalloc() and expect them to be in order later. I wonder how this ever
worked.

On initialization, we first do the ioremap and then register the led devices.
On deinitialization, we do it in reverse order. This prevents someone calling
into the brightness_set functions with an invalid latch_address.

The tasklet checks RAW.BLOCK twice, and does not check RAW.XFER. This is
obviously wrong, and could theoretically cause the driver to hang.

The "Documentation" section of this file mentions that when an interface
change is made, I should be CCed with info about the change (so that
man-pages can document it). Additionally request that this info be CCed

Fix infinite recursive notifier in the fbdev layer. This causes recursive
locking. Dmitry Baryshkov found the problem and confirmed that the patch
fixes the bug.
After doing
# echo 1 > /sys/class/graphics/fb0/blank
I got the following in my kernel log:

When userspace uses SIGIO notification and forgets to disable it before
closing file descriptor, rtc->async_queue contains stale pointer to struct
file. When user space enables again SIGIO notification in different
process, kernel dereferences this (poisoned) pointer and crashes.
So disable SIGIO notification on close.

At some point during the 2.6.27 development cycle two new fields were added
to the SELinux context structure, a string pointer and a length field. The
code in selinux_secattr_to_sid() was not modified and as a result these two
fields were left uninitialized which could result in erratic behavior,
including kernel panics, when NetLabel is used. This patch fixes the
problem by fully initializing the context in selinux_secattr_to_sid() before
use and reducing the level of direct context manipulation done to help
prevent future problems.
Please apply this to the 2.6.27-rcX release stream.

Impact: segfault on build of a 32-bit relocatable kernel
When converting arch/x86/boot/compressed/relocs.c to support unlimited
sections, the computation of sym_strtab in walk_relocs() was done
incorrectly. This causes a segfault for some people when building the
relocatable 32-bit kernel.

This fixes a regression that came with 934b2857cc576ae53c92a66e63fce7ddcfa74691
("[S390] nohz/sclp: disable timer on synchronous waits.").
If udelay() gets called from a disabled context it sets the clock comparator
to a value where it expects the next interrupt. When the interrupt happens
the clock comparator gets not reset and therefore the interrupt condition
doesn't get cleared. The result is an endless timer interrupt loop.
In addition this patch fixes also the following:
rcutorture reveals that our __udelay implementation is still buggy,
since it might schedule tasklets, but prevents their execution:
NOHZ: local_softirq_pending 42
NOHZ: local_softirq_pending 02
NOHZ: local_softirq_pending 142
NOHZ: local_softirq_pending 02
To fix this we make sure that only the clock comparator interrupt
is enabled when the enabled wait psw is loaded.
Also no code gets called anymore which might schedule tasklets.

In case of an adapter reopen all rports have to be deleted from the
environment. This should only happen for already registered rports
otherwise fc_remote_port_delete is called with a NULL pointer.

Each adapter reopen trigger automatically a scan_port task which
is waiting for the ERP to be finished before further processing.
Since the initial device setup enqueues adapter, port and LUN which
are individual ERP actions, this process would start after
everything is done. Unfortunately the port_reopen requires another
scheduled work to be finished which is queued after the automatic
scan_port -> deadlock !
This fix creates an own work queue for ERP based nameserver requests.

Now that we removed the long messages for the bit error threshold
data, put the data in the hba trace. This way, we get a short warning
for the threshold event from the hardware and have the data in the
trace for further analysis.

Reduce the size of zfcp data structures by removing unused and
redundant members. scsi_lun is only the mangled version of the
fcp_lun. So, remove the redundant field and use the fcp_lun instead.
Since the queue lock and the pci_batch indicator are only used in the
request queue, move them from the common queue struct to the adapter
struct.

Changing the zfcp behaviour from always having the nameserver port
open to an on-demand strategy. This strategy reduces the use of
limited resources like port connections. The patch provides a common
infrastructure which could be used for all WKA ports in future.
Also reduce the number of nameserver lookups by changing the zfcp
behaviour of always querying the nameserver for the corresponding
destination ID of the remote port. If the destination ID has changed
during the reopen process we will be informed and then trigger a
nameserver query on demand.

- Remove unused references and declarations, including one instance
of the FC ls_adisc struct that has been defined twice.
- Also remove the flags COMMON_OPENING, COMMON_CLOSING,
ADAPTER_REGISTERED and XPORT_OK that are only set and cleared, but
not checked anywhere.
- Remove the zfcp specific atomic_test_mask makro. Simply use
atomic_read directly instead.
- Remove the zfcp internal sg helper functions and switch the places
where it is still used to call sg_virt directly.
- With the update of the QDIO code, the QDIO data structures no
longer use the volatile type qualifier. Now we can also remove the
volatile qualifiers from the zfcp code.

Fix by making csdev->buffer explicitly an unsigned char and dropping

Rework of SMTC support to make it work with the new clock event system,
allowing "tickless" operation, and to make it compatible with the use of
the "wait_irqoff" idle loop. The new clocking scheme means that the
previously optional IPI instant replay mechanism is now required, and has
been made more robust.
