11025e8552 via-rng: enable secondary noise source on CPUs where it is present
In the padlock spec:

"SRC Bits[9:8] Noise source select (I): These bits control the two noise
 sources on the processor that input bits to the accumulation buffers.
 On Nehemiah processors prior to stepping 8, these bits are reserved
 and undefined. The default RESET state is both bits = 0."

5bd91f18be tpm.c: fix crash during device removal
The clean up procedure now uses platform device "release" callback to
handle memory clean up.  For this purpose "release" function callback was
added to struct tpm_vendor_specific, so hw device driver provider can get
called when it is safe to remove all allocated resources.

This is supposed to fix a bug in device removal, where device while in
receive function (waiting on timeout) was prone to segfault, if the
tpm_chip struct was unallocated before the timeout expired (in
tpm_remove_hardware).

96c5865559 Allow auto-destruction of loop devices
This allows a flag to be set on loop devices so that when they are
closed for the last time, they'll self-destruct.

In general, so that we can automatically allocate loop devices (as with
losetup -f) and have them disappear when we're done with them.

In particular, right now, so that we can stop relying on the hackish
special-case in umount(8) which kills off loop devices which were set up by
'mount -oloop'.  That means we can stop putting crap in /etc/mtab which
doesn't belong there, which means it can be a symlink to /proc/mounts, which
means yet another writable file on the root filesystem is eliminated and the
'stateless' folks get happier...  and OLPC trac #356 can be closed.

The mount(8) side of that is at

8f47f0b688 dcdbas: add DMI-based module autloading
DMI autoload dcdbas on all Dell systems.

This looks for BIOS Vendor or System Vendor == Dell, so this should
work for systems both Dell-branded and those Dell builds but brands
for others.  It causes udev to load the dcdbas module at startup,
which is used by tools called by HAL for wireless control and
backlight control, among other uses.

Thanks to Kay Sievers for figuring out how to do this with a single alias.

f661197e0a Genericizing iova.[ch]
I would like to potentially move the sparc64 IOMMU code over to using
the nice new drivers/pci/iova.[ch] code for free area management..

In order to do that we have to detach the IOMMU page size assumptions
which only really need to exist in the intel-iommu.[ch] code.

This patch attempts to implement that.

d9afa43532 riscom8: fix SMP brokenness
After analyzing the elements that save_flags/cli/sti/restore_flags were
protecting, convert their usages to a global spinlock (the easiest and
most obvious next-step).  There were some usages of flags being
intentionally cached, because the code already knew the state of
interrupts.  These have been taken into account.

This allows us to remove CONFIG_BROKEN_ON_SMP.  Completely untested.

8004a8c974 ide-tape: refactor the debug logging facility
Teach the debug logging macro to differentiate between log levels based on the
type of debug level enabled specifically instead of a threshold-based one.
Thus, convert tape->debug_level to a bitmask that is written to over /proc.

Also,
- cleanup and simplify the debug macro thus removing a lot of code lines,
- get rid of unused debug levels,
- adjust the loglevel at several places where it was simply missing (e.g.
  idetape_chrdev_open())
- move the tape ptr initialization up in idetape_chrdev_open() so that we can
  use it in the debug_log macro earlier in the function.

594765a731 ide-pci-generic: kill the unused ifdef/endif/MODULE code
with module_param macro, the __setup code can be killed now:
	const __setup("all-generic-ide", ide_generic_all_on);

and the module name "generic.ko" is not descriptive to its functionality,
can be changed in Makefile, the "ide-pci-generic.ko" is better.

the ide-pci-generic.all-generic-ide parameter also documented
in Documentation/kernel-parameters.txt

The commit 139ddfcab5 ("ide: move handling of
I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe
check vs ide_hwif_request_regions() call (so that we now reserve I/O regions
before checking for hwif->noprobe).  However ide-generic host driver depended
on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots.

Fix it by passing only indexes of non-empty slots to ide_device_add_all()
from ide_generic_init().
