fe4a3c7a20 mmc: Allow host drivers to specify a max block size
Most controllers have an upper limit on the block size. Allow the host
drivers to specify this and make sure we avoid hitting this limit.

7146f0d3bd tifm_7xx1: switch from workqueue to kthread
As there's only one work item (media_switcher) to handle and it's effectively
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.

29a002776b [PATCH] kexec: Avoid migration of already disabled irqs (ia64)
This patch fixes up ia64 kexec support for HP rx2620 hardware.  It does
this by skipping migration of already disabled irqs.  This is most likely a
problem on other ia64 platforms as well, but I've only been able to
reproduce it on one machine so far.

The full story is that handle_bad_irq() gets invoked before starting the
new kernel without this patch.  This seems to happen when fixup_irqs()
calls generic_handle_irq() on already migrated (and disabled) irqs.  So by
avoiding migration of disabled irqs we stay away of handle_bad_irq().

The code has been tested on three different ia64 machines, all with good
results.  It is possible to trigger the same bug by offlining a processor
using echo 0 > /sys/devices/system/cpu/cpuX/online.

See report: http://marc.theaimsgroup.com/?l=linux-kernel&m=116599593200888&w=2

flush_workqueue() is not allowed to be called in the softirq context.
However, aio_complete() called from I/O interrupt can potentially call
put_ioctx with last ref count on ioctx and triggers bug.  It is simply
incorrect to perform ioctx freeing from aio_complete.

The bug is trigger-able from a race between io_destroy() and aio_complete().
A possible scenario:

cpu0                               cpu1
io_destroy                         aio_complete
  wait_for_all_aios {                __aio_put_req
     ...                                 ctx->reqs_active--;
     if (!ctx->reqs_active)
        return;
  }
  ...
  put_ioctx(ioctx)

                                     put_ioctx(ctx);
                                        __put_ioctx
                                          bam! Bug trigger!

The real problem is that the condition check of ctx->reqs_active in
wait_for_all_aios() is incorrect that access to reqs_active is not
being properly protected by spin lock.

This patch adds that protective spin lock, and at the same time removes
all duplicate ref counting for each kiocb as reqs_active is already used
as a ref count for each active ioctx.  This also ensures that buggy call
to flush_workqueue() in softirq context is eliminated.

017f2e37ae [SCSI] sd: udev accessing an uninitialized scsi_disk field results in a crash
sd_probe() calls class_device_add() even before initializing the
sdkp->device variable. class_device_add() eventually results in the user mode
udev program to be called. udev program can read the the allow_restart
attribute of the newly created scsi device. This is resulting in a crash as
the show function for allow_restart (i.e sd_show_allow_restart) returns the
attribute value by reading the sdkp->device->allow_restart variable. As the
sdkp->device is not initialized before calling the user mode hotplug helper,
this results in a crash.
	The patch below solves it by calling class_device_add() only after the
necessary fields in the scsi_disk structure are initialized properly.

7728098967 ahci/pata_jmicron: fix JMicron quirk
For all JMicrons except for 361 and 368, AHCI mode enable bits in the
Control(1) should be set.  This used to be done in both ahci and
pata_jmicron but while moving programming to PCI quirk, it was removed
from ahci part while still left in pata_jmicron.

The implemented JMicron PCI quirk was incorrect in that it didn't
program AHCI mode enable bits.  If pata_jmicron is loaded first and
programs those bits, the ahci ports work; otherwise, ahci device
detection fails miserably.

This patch makes JMicron PCI quirk clear SATA IDE mode bits and set
AHCI mode bits and remove the respective part from pata_jmicron.
Tested on JMB361, 363 and 368.

435f8a605d Revert "[PATCH] fix typo in geode_configre()@cyrix.c"
This reverts commit e4f0ae0ea6.

It's not wrong, but it's not right either, and everybody seems to agree
that the right fix is probably to do the ccr3 write after the ccr4 one
(and that we also should clean it up a bit).  And after that we need to
really validate that all the bits that we write to ccr4 actually do
work.

The old 2.6.19 code was insane, and basically didn't change ccr4 at all
(even though it certainly looks like it was the *intent* to do so).  So
let's revert the change that may fix things, just because it's not what
was actually ever tested when the code was written, even if it _was_ the
intent.

There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was
started by the patch that now gets reverted, and that discussion may
well contain the proper long-term fix.

a55eb05a57 spidernet : fix memory leak in spider_net_stop
We forget to call spider_net_free_rx_chain_contents which does the
actual dev_kfree_skb. New skbs are allocated from skbuff_head_cache
on each "ifconfig up" letting the cache grow infinitely.

This patch fixes it.

e100: fix napi ifdefs removing needed code

From: Auke Kok <auke-jan.h.kok@intel.com>

The e100 driver is NAPI mode only. We need to netif_poll_disable
during suspend and shutdown. The non-NAPI driver code was removed
and is only avaiable in the out-of-tree e100 kernel driver.
