63c2f782e8 [POWERPC] Add "is_power_of_2" checking to log2.h.
Add the inline function "is_power_of_2()" to log2.h, where the value
zero is *not* considered to be a power of two.

861be32ce7 [POWERPC] ps3: bind interrupt to cpu
Change the PS3 irq allocation routines to take an argument indicating which
cpu (processor thread) the interrupt should be serviced on.

The current system configuration favors device interrupts that are serviced
on cpu0, so that is used as the default.

43d80439c5 [POWERPC] ps3: system bus minor mmio fix
Fix two minor bugs in the PS3 system bus mmio region code.  First, on error or
when freeing a region, retain the bus_addr and len fields to allow subsequent
calls to create the region.  Second, correct the region address argument to the
lv1_unmap_device_mmio_region() call.

Fixes modprobe/rmmod of some drivers.

f25222b995 [POWERPC] cpm_uart: OF-related fix for CPM1
This makes cpm uart able to work using OF-passed parameters
in case of CPM stuff (found on most mpc8xx reference and custom
boards). The idea is to keep ppc stuff working yet making it able to be
used for powerpc.

877cbd36b2 bonding: modify sysfs support to permit multiple loads
The existing code would blindly attempt to create the
bonding_masters file (in /sys/class/net) every time the module was
loaded.  When the module is loaded multiple times (which is the
historical method used by initscripts and sysconfig to create multiple
bonding interfaces), this caused load failure of the second module load
attempt, as the creation request would fail.

	This changes the code to note the failure, arrange to not remove
the bonding_masters file upon module exit, and then return success.

	Bonding interfaces created by the second or subsequent loads of
the module will not exist in bonding_masters.  This is not a significant
change, as previously only the interfaces from the most recent load of
the module would be listed.  Both situations are less than optimal, but
this case permits compatibility with existing distro configuration
scripts, and is consistent.

	Note that previously, the sysfs create request would overwrite
the exsting bonding_masters file and succeed, allowing multiple loads of
the module.  The sysfs code has recently changed to return an error if
the file being created already exists.

	Patrick McHardy <kaber@trash.net>, who reported this problem,
observed crashes on the old kernel (before sysfs checked for
duplicates).  I did not experience such crashes, but this change should
resolve them.

The code to select names for the bonding interfaces was, for the

079ca7da1e bonding.h: "extern inline" -> "static inline"
"extern inline" generates a warning with -Wmissing-prototypes and I'm
currently working on getting the kernel cleaned up for adding this to
the CFLAGS since it will help us to avoid a nasty class of runtime
errors.

If there are places that really need a forced inline, __always_inline
would be the correct solution.

bf34570729 driver for Silan SC92031 netdev
This is a driver for the Silan SC92031/Rsltek 8139D NIC chip.

This chip is found on at least one counterfeit Encore ENL832-TX-RENT NIC
[1], which came with a mini-CD with the 2.4 driver.  A slightly older
version of the driver was found at [2].  The main difference between them
is that the newer one has a small bugfix in the RX path, a lot of
gratuitous renaming of functions, all the printable strings changed to show
as a "Rsltek 8139D" [sic], and a PCI ID of 8139 instead of 2031.  The
driver on this patch is a rewrite of the vendor drivers (based mostly on
the older one).

Changes from the previous patch sent to netdev:
- Use MMIO instead of PIO
- Changed TX bounce buffers allocation
- Use skb_copy_and_csum_dev
- Several small bug fixes
- Tested for more than just a few minutes each time

[1] See http://www.encore-usa.com/faq.php under ENL832-TX-RENT for more
    information
[2] Look for SL_LINUX.ZIP (which is really a .tar.gz) at
    http://broadbandforum.in/dataone_Intex_LAN_cardlinux-t4207-s15.html
[3] To compile on 2.6.17, simply add back the last argument to the
    interrupt handler in two places, and copy the boolean declarations
    from 2.6.19

0ce34bc8f7 [PATCH] zd1211rw: Remove addressing abstraction
Instead of passing our own custom 32-bit addresses around and
translating them, this patch makes all our register address constants
absolute and removes the translation.

There are two ugly parts:
 - fw_reg_addr() is needed to compute addresses of firmware registers, as this
   is dynamic based upon firmware
 - inc_addr() needs a small hack to handle byte vs word addressing

However, both of those are only small, and we don't use fw_regs a whole
lot anyway.

The bonuses here include simplicity and improved driver readability. Also, the
fact that registers are now referenced by 16-bit absolute addresses (as
opposed to 32-bit pseudo addresses) means that over 2kb compiled code size has
been shaved off.

Includes some touchups and sparse fixes from Ulrich Kunitz.

ee30276774 [PATCH] zd1211rw: Consistency for address space constants
The zd1211rw address space has confused me once too many times. This
patch introduces the following naming notation:

Memory space is split into segments (cr, fw, eeprom) and segments may
contain components (e.g. boot code inside eeprom). These names are
arbitrary and only for the description below:

x_START: Absolute address of segment start
(previously these were named such as CR_BASE_OFFSET, but they weren't
really offsets unless you were considering them as an offset to 0)

x_LEN: Segment length

x_y_LEN: Length of component y of segment x

x_y_OFFSET: Relative address of component y into segment x. The absolute
address for this component is (x_START + x_y_OFFSET)

I also renamed EEPROM registers to EEPROM data. These 'registers' can't
be written to using standard I/O and really represent predefined data
from the vendor.

Hopefully this will make it more maintainable and less error prone.
Code makes use of search_exception_tables(). Since it calls this

This way it's easy to use the already present infrastructure of fixup

two ETR units can be connected to a machine. If the clock deviates

The initialization of the dasd_eer code is one of the last steps of the
dasd driver initialization. When initialization fails in one of the
earlier steps, the dasd_exit function is called to clean up what has been
done so far. So the dasd_eer_exit function may be called, although the
dasd_eer_init function wasn't called before and dasd_eer_exit tries to
unregister a misc device that wasn't registered, which results in a BUG.

Make sure that dasd_eer_exit can be called without initialization. Use a
dynamically allocated struct miscdevice instead of a static one, so we
only try to unregister the device if it exists and was actually registered.

Add new quirk HID_QUIRK_SKIP_OUTPUT_REPORTS to skip output reports
when enumerating reports on a hid-input device. Add this quirk and
HID_QUIRK_MULTI_INPUT to 0810:0001.

PantherLord Twin USB Joystick, 0810:0001 has separate input reports
for 2 distinct game controllers in the same interface, so it needs
HID_QUIRK_MULTI_INPUT. However, the device also contains one output
report per controller which is used to control the force feedback
function, and we do not want those to appear as separate input
devices as well. The simplest approach seems to be to add a quirk to
skip output reports on 0810:0001, and allow the force feedback
driver to handle those.

1033ff670d IB/srp: Don't wait for response when QP is in error state.
When there is a call to send_tsk_mgmt SRP posts a send and waits for 5
seconds to get a response.

When the QP is in the error state it is obvious that there will be no
response so it is quite useless to wait.  In fact, the timeout causes
SRP to wait a long time to reconnect when a QP error occurs. (Each
abort and each reset_device calls send_tsk_mgmt, which waits for the
timeout).  The following patch solves this problem by identifying the
failure and returning an immediate error code.

062dbb69f3 IB: Return qp pointer as part of ib_wc
struct ib_wc currently only includes the local QP number: this matches
the IB spec, but seems mostly useless. The following patch replaces
this with the pointer to qp itself, and updates all low level drivers
and all users.

This has the following advantages:
- Ability to get a per-qp context through wc->qp->qp_context
- Existing drivers already have the qp pointer ready in poll cq, so
  this change actually saves a tiny bit (extra memory read) on data path
  (for ehca it would actually be expensive to find the QP pointer when
  polling a CQ, but ehca does not support SRQ so we can leave wc->qp as
  NULL for ehca)
- Users that need the QP number can still get it through wc->qp->qp_num

Use case:

In IPoIB connected mode code, I have a common CQ shared by multiple
QPs.  To track connection usage, I need a way to get at some per-QP
context upon the completion, and I would like to avoid allocating
context object per work request just to stick a QP pointer into it.
With this code, I can just use wc->qp->qp_context.

serialized with itself, I found it more convenient to use kthread instead of
workqueue. This also allows for a working implementation of suspend/resume,
which were totally broken in the past version.

6412d92731 tifm_7xx1: Merge media insert and media remove functions
Hardware does not say whether card was inserted or removed when reporting
socket events. Moreover, during suspend, media can be removed or switched
to some other card type without notification. Therefore, for each socket
in the change set the following is performed:
1. If there's active device in the socket it's unregistered
2. Media detection is performed
3. If detection recognizes supportable media, new device is registered

This patch also alters some macros and variable names to enhance clarity.

8e02f8581c tifm_sd: restructure initialization, removal and command handling
In order to support correct suspend and resume several changes were needed:
1. Switch from work_struct to tasklet for command handling. When device
suspend is called workqueues are already frozen and can not be used.
2. Separate host initialization code from driver's probe and don't rely
on interrupts for host initialization. This, in turn, addresses two
problems:
 a) Resume needs to re-initialize the host, but can not assume that
    device interrupts were already re-armed.
 b) Previously, probe will return successfully before really knowing
    the state of the host, as host interrupts were not armed in time.
    Now it uses polling to determine the real host state before returning.
3. Separate termination code from driver's remove. Termination may be caused
by resume, if media changed type or became unavailable during suspend.

fba68bd2da mmc: Add support for SDHC cards
Thanks to the generous donation of an SDHC card by John Gilmore, and
the surprisingly enlightened decision by the SD Card Association to
publish useful specs, I've been able to bash out support for SDHC. The
changes are not too profound:

i) Add a card flag indicating the card uses block level addressing and
check it in the block driver. As we never took advantage of byte-level
addressing, this simply involves skipping the block -> byte
translation when sending commands.

ii) The layout of the CSD is changed - a set of fields are discarded
to make space for a larger C_SIZE. We did not reference any of the
discarded fields except those related to the C_SIZE.

iii) Read and write timeouts are fixed values and not calculated from
CSD values.

iv) Before invoking SEND_APP_OP_COND, we must invoke the new
SEND_IF_COND to inform the card we support SDHC.

9e9dc5f29f mmc: Power quirk for ENE controllers
Support for these devices was broken for 2.6.18-rc1 and later by commit
146ad66eac, which added voltage level support.

This restores the previous behaviour for these devices by ensuring that when
the voltage is changed, only one write to set the voltage is performed.

It may be that both writes are needed if the voltage is being changed between
two non-zero values or that it's safe to ensure that only one write is done
if the hardware only supports one voltage; I don't know whether either is the
case nor can I test since I have only the one SD reader (1524:0550), and it
supports just the one voltage.

3e643e77a9 Altix: Add ACPI SSDT PCI device support (hotplug)
Support for dynamic loading and unloading of ACPI SSDT tables upon slot
hotplugs and unplugs.

On SN platforms, we now represent every populated root bus slot with a single
ACPI SSDT table containing info for every device and PPB attached to the slot.
 These SSDTs are generated by the prom at initial boot and hotplug time.  The
info in these SSDT tables is used by the SN kernel IO "fixup" code (which is
called at boot and hotplug time).

On hotplugs (i.e.  enable_slot()), if running with an ACPI capable prom,
attempt to obtain a new ACPI SSDT table for the slot being hotplugged.  If
successful, add the table to the ACPI namespace (acpi_load_table()) and then
walk the new devices and add them to the ACPI infrastructure (acpi_bus_add()).

On hot unplugs (i.e.  disable_slot()), if running with an ACPI capable prom,
attempt to remove the SSDT table associated with the slot from the ACPI
namespace (acpi_unload_table_id()) and infastructure (acpi_bus_trim()).

From: John Keller <jpk@sgi.com>

 A bug was fixed where the sgi hotplug driver was removing
 the slot's SSDT table from the ACPI namespace a bit too early in
 disable_slot(). Also, we now call acpi_bus_start() subsequent
 to acpi_bus_add().

b7a6980630 ACPICA: _CID support for PCI Root Bridge detection.
Implemented _CID support for PCI Root Bridge detection. If the _HID
does not match the predefined root bridge IDs, the _CID list (if present)
 is now obtained and also checked for an ID match

d1fdda83f7 ACPICA: Fix race condition with AcpiWalkNamespace.
Fixed a problem with a possible race condition between threads executing
AcpiWalkNamespace and the AML interpreter. This condition was removed by
modifying AcpiWalkNamespace to (by default) ignore all temporary
namespace entries created during any concurrent control method execution

9bc75cff49 ACPICA: Eliminate control method 2-pass parse/execute.
Completed an AML interpreter performance enhancement for control method
execution. Previously a 2-pass parse/execution, control methods are now
completely parsed and executed in single pass. This improves overall
interpreter performance by ~25%, reduces code size, and reduces CPU stack use.

1ba753acb3 ACPICA: Re-implement interpreters' "serialized mode"
Enhanced the implementation of the interpreters'
serialized mode (boot with "acpi_serialize" to set
acpi_glb_all_methods_serialized flag.)
When this mode is specified, instead of creating a serialization
semaphore per control method, the interpreter lock is
simply no longer released before a blocking operation
during control method execution. This effectively makes
the AML Interpreter single-threaded. The overhead of a
semaphore per-method is eliminated.
