USB generic driver
high speed support

USB generic driver
clean up get_iface again :)

USB generic driver
replace usage of interface index with calls to usb_ifnum_to_if (forgot this in 1.88)

USB generic driver
remove calls to usb_driver_release_interface
(not needed when disconnect is called)

 - make sure cd->buffer is always inside a page - previously if an
   entry fit perfectly in the remainder of a page, cd->buffer would
   end up pointing past the end of that page.

 - make sure num_entry_words is always correct, even on the error
   path.

This increases the DART table to use the full size.  We allocate a full
16MB page anyway, so there's no difference in memory consumption. 

Thanks to Ben for spotting this, it was left over from debugging...

This fixes a bug in the iommu allocator that causes it to behave
strangely when a fair size of the table is allocated. 

Thanks to Andrew Gallatin for finding this.

This patch from Alan Stern <stern@rowland.harvard.edu> fixes a bug in
the current USB code that causes khubd to hang when a device is removed
from the system, thereby preventing any future USB device changes (like
adding or removing other devices) from happening.

Both Andrew and I can easily duplicate this bug against the current -bk
tree. 

It's not a perfect fix, but it works for now, and I will spend the next
week working on restructuring the code so this is handled properly.

It has been dead since kernel 2.5.18.

TiVo IDE support was never merged only this option was (in 2.4.0-test2), sigh.

filldir and getdents should check return values of put_user etc. The
generic code has been fixed but the ppc64 compat versions have not.

This replaces six duplicated implementations of various quality of
sys32_mount with a shiny new compat_sys_mount().

It's been tested on parisc64 and sparc64 and fixes a bug exposed by the
latest revision of Debian's initscripts.  Thanks to Arnd Bergmann and
Dave Miller for their suggestions, fixes and testing.  Please apply.

Remove include of <asm/setup.h> from cmdlinepart.c.  This is not be needed
for i386 (it builds fine with this patch), and ia64 doesn't supply a
setup.h.

asm/setup.h contains a hodge-podge of stuff with no real
consistency between architectures.  It appears to be
included mainly by arch-specific drivers:
	acsi (Atari disks)
	amiflop (Amiga floppy)
	z2ram (ZorroII ram disk)
	amiserial (Amiga serial)
	...
and under arch-specific #ifdefs:
	fbcon (under __mc68000__ or CONFIG_APUS)
	fonts (ditto)
	logo (CONFIG_M68K)
	...

The problem is that we don't clear out the efi_time_t buffer before asking
EFI to fill it in.  EFI doesn't always write the entire buffer (in
particular, the alarm time only supports one second resolution, so the
nanosecond field is often untouched).

The effect is that 'cat /proc/driver/efirtc' shows garbage in the
nanoseconds part of the alarm time, and sometimes artifacts like bogus
alarm date and junk after the actual end of the text.

This patch fixes a bug where the return value for a permission call is not 
checked.

The bug was introduced when I added some code in the following changeset:

<http://linux.bkbits.net:8080/linux-2.5/diffs/security/selinux/hooks.c@1.19?nav=index.html|src/|src/security|src/security/selinux|hist/security/selinux/hooks.c>

Code was added after this line:

	err = avc_has_perm(isec->sid, node_sid, SECCLASS_NODE, node_perm, NULL, &ad);

without adding an explicit check of 'err', which was previously returned
from the function rather than being checked.  i.e. it would drop through
to:

	out:	
 		return err;

 	}

With the new code added, err can (and typically would) be overwritten with 
a successful value, causing the permission check to not deny permission if 
needed.  The intended denial would have been logged.

The patch below fixes this problem.

This patch ensures that cpu_khz is adjusted on cpufreq notifications even
when the tsc timesource is not in use.  It fixes the mostly cosmetic issue
when using the ACPI PM timesource of /proc/cpuinfo not being properly
updated when cpu frequency was lowered.

System call speedup part 2.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

The purpose of this is to speed up system calls on s390.  I managed to
squeeze about 65 cycles from each system call.  This improved e.g.  getpid()
from 232 to 157 cycles.  As a nice side-effect it simplified the uaccess
functions considerably.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

s390 tape driver changes:
 - Prevent offline while device is in use.
 - Do not use bus_id string in debug feature messages.
 - Check for IS_ERR(irb) error conditions in interrupt handler.
 - Fix removing tape discipline modules.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

s390 network driver changes:
 - ctc/lcs/qeth: prevent a ccw-device to be grouped multiple times.
 - icuv: clear correct field in iucv_register_program if no userid is specified.
 - lcs: fix online/offline cycle again.
 - lcs: fix ungrouping of lcs group device. The channels of the lcs card
   should be offline afterwards.
 - lcs: don't do netif_stop_queue if no tx buffer is available, just
   return -EBUSY and drop the packets.

z/VM monitor stream changes:
 - Correct sysctl vs. module ref-counting.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

dasd device driver changes:
 - After a state change interrupt restart all running i/o on queue
   and reset device timer.
 - Improve some debug messages.
 - Lower timeout of reserve/release/steal_lock to 2 seconds.
 - Fix BIODASDPSRD ioctl.
 - Replace ro_flag, use_diag_flag and disconnect_error_flag words by bits.
 - Use BLKPG_DEL_PARTITION ioctl instead of a call to delete_partition because
   delete_partition is not an exported function. Since dasd_destroy_partitions
   can't do blkdev_get because dasd_open would fail, keep the block device
   open as long as partitions exist. This in turn requires a different
   approach to the open vs. offline race.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

s390 core changes:
 - Fix return type of some system call functions (long vs. int).
 - Fix prototypes for compat system call handlers.
 - Correct some bugs in the compat system call wrappers.
 - Fix broken pointer arithmetic which causes problems with
   gcc 3.4 and -march=z990
 - Remove unnecessary #ifndef & optimize inline assemblies in spinlock.h.
 - Improve handling of deferred condition code 1.
 - New default configuration.

I ran into an ipc hang while trying to shutdown a database.  The problem is
due to missing sem_unlock() in find_undo().

copy_from_user() returns non-zero on faults..

This fixes a problem where cy_wait_until_sent() miscalculates (calculate
-1 on a unsigned long) the "char_time" parameter passed to
schedule_timeout().

Fix that by making it a signed long, and checking for negative value.

This helps vmware users running vmware on x86-64 - vmnet tries to set up a bridge.
Emulate these ioctls. The bridge has more ioctls on its bridge device, but these
don't seem to be needed here.

Don't register disabled nodes.  Hits on x86-64 when there is a node with no memory.
X86-64 shares this code with i386.

The newest CVS glibc assumes that Linux >=2.6.4 always passes d_type.
This patch adds this to the 32bit getdents on x86-64 too

"acpi_wake_gpes_always_on" boot flag for old GPE behaviour

into intel.com:/home/lenb/src/linux-acpi-test-2.6.5

Implemented support for "wake" GPEs via interaction between
GPEs and the _PRW methods.  Every GPE that is pointed to by
one or more _PRWs is identified as a WAKE GPE and by default
will no longer be enabled at runtime.  Previously, we were
blindly enabling all GPEs with a corresponding _Lxx or _Exx
method - but most of these turn out to be WAKE GPEs anyway.
We believe this has been the cause of thousands of
"spurious" GPEs on some systems.

This new GPE behavior is can be reverted to the original
behavior (enable ALL GPEs at runtime) via a runtime flag.

Fixed a problem where aliased control methods could not
access objects properly.  The proper scope within the
namespace was not initialized (transferred to the target of
the aliased method) before executing the target method.

Fixed a potential race condition on internal object
deletion on the return object in AcpiEvaluateObject. 

Integrated a fix for resource descriptors where both
_MEM and _MTP were being extracted instead of just _MEM.
(i.e. bitmask was incorrectly too wide, 0x0F instead of 0x03.)

Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName,
preventing a fault in some cases.

Updated Notify() values for debug statements in evmisc.c

Return proper status from AcpiUtMutexInitialize,
not just simply AE_OK.
