91a6902958 sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes
Well, first of all, I don't want to change so many files either.

What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.

In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(

Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)

Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.

Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

7b595756ec sysfs: kill unnecessary attribute->owner
sysfs is now completely out of driver/module lifetime game.  After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners.  Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.

This patch kills now unnecessary attribute->owner.  Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

For more info regarding lifetime rule cleanup, please read the
following message.

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

Add help info for BLK_DEV_SD referring to its use in
SATA or PATA driver configurations.

Add help text for "ATA" indicating that it probably needs

Salyzyn, Mark
94774a3a8e [SCSI] aacraid: fix shutdown handler to also disable interrupts.
Moves quiesce, thread and interrupt shutdown into aacraid drivers'
.shutdown handler. This fix to the aac_shutdown handler will remove the
superfluous reset of the adapter during a (clean) kexec.

This fix may mitigate the active investigation 'kexec and aacraid
broken' but it is unlikely to affect the root cause (issue likely
present in both kexec and kdump). This patch reduces the chance the
problem will occur with a kexec. The fix for root cause is currently
expected to be the minimum value check to the aacraid.startup_timeout
driver variable after an adapter reset within aacraid_commit_reset.patch
submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.

632155e659 potential parse error in ifdef
I have made a tool to parse the kernel that does not pre-process the
source.  That means that my parser tries to parse all the code, including
code in the #else branch or code that is not often compiled because the
driver is not very used (or not used at all).  So, my parser sometimes
reports parse error not originally detected by gcc.  Here is my (first)
patch.

2.6.21-rc5-mm2 VFS panics unable to find my root on /dev/sda2, but boots

Make sure there's a late_initcall to scsi_complete_async_scans when it's
built in, so a monolithic SCSI_SCAN_ASYNC kernel can rely on the scans
being completed before trying to mount root, even if they're slow.

8fdcf86af6 [SCSI] aic94xx: asd_clear_nexus should fail if the cleared task does not complete
Every so often, the driver will call asd_clear_nexus to clean out a task.
It is supposed to be the case that the CLEAR NEXUS does not go on the done
list until after the task itself has been put on the done list, but for
some reason this doesn't always happen.  Thus, the
wait_for_completion_timeout call times out, and we return success.  This
makes libsas free the task even though the task hasn't completed, leading
to a BUG_ON message from aic94xx_hwi.c around line 341.  We should return
failure from asd_clear_nexus so that libsas tries again; at a bare minimum
it shouldn't be freeing active tasks.  I _think_ this will fix one of
the SCB timeout crash problems (though I've not been able to reproduce
it lately...)

1208bab5d0 [SCSI] aacraid: apply commit config for reset_devices flag
Under some conditions associated with the unclean transition to kdump,
the aacraid adapters will view the array as foreign and not export it to
prevent access and data manipulation. The solution is to submit a commit
configuration to export the devices since this is a expected behavior
when transitioning to a kdump kernel.

This patch adds the aacraid.reset_devices flag and when either this or
the global reset_devices flag is set, ensures that a commit config is
issued and extends the startup_timeout if it is set less than 5 minutes.

e8edc6e03a Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

Cross-compile tested on

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up
	arm
	i386 i386-up i386-defconfig i386-allnoconfig

On digging into it, it turned out that the customer was probing an
aacraid device with an INQUIRY of 8 bytes.  The way aacraid works, it
was blindly trying to use aac_internal_transfer to copy the container
name to byte 16 of the inquiry data, resulting in a negative transfer
length.  It then copies over the whole of kernel memory before
dropping off the end.

2ab01efd1d [SCSI] aacraid: Correct sa platform support. (Was: [Bug 8469] Bad EIP value on pentium3 SMP kernel-2.6.21.1)
http://bugzilla.kernel.org/show_bug.cgi?id=8469

As discussed in the bugzilla outlined below, we have an sa based
(Mustang) RAID adapter on the system, a Dell PERC2/QC. Affected
controllers are HP NetRAID, Adaptec AAC-364, Dell PERC2/QC or Adaptec
5400S. This problem  coincides with the introduction of the adapter_comm
and adapter_deliver platform functions (Message [PATCH 1/4] aacraid:
rework communication support code, January 23 2007, which initially
migrated to 2.6.21)

The panic occurs with an uninitialized adapter_deliver platform function
pointer. The enclosed patch, unmodified as tested by Rainer, solves the
problem.

d116a7bc6a [SCSI] stex: fix reset recovery for console device
After reset completed, the scsi error handler sends out TEST_UNIT_READY
to the device. For 'normal' devices the command will be handled by firmware.
However, because the RAID console only interfaces to scsi mid layer, the
firmware will not process the command for it. This will make the console to
be offlined right after reset. Add the handling in driver to fix this problem.

e0b2e597d5 [SCSI] stex: fix id mapping issue
The correct internal mapping of stex controllers should be:
id:0~15, lun:0~7 (st_shasta)
id:0, lun:0~127 (st_yosemite)
id:0~127, lun:0 (st_vsc and st_vsc1)

This patch reports the internal mapping to scsi mid layer,  eliminating
the translation between scsi mid layer and firmware. To achieve this
goal, we also need to:
-- fail the REPORT_LUNS command for st_shasta because the
   firmware is known to not report all actual luns
-- add an entry in scsi_devindo.c to force sequential lun scan
   (for st_shasta controllers)
-- fail the REPORT_LUNS command for console device
-- remove special handling of REPORT_LUNS command for
   st_yosemite, as there is no translation mapping now

Currently ipr always returns success from eh_dev_reset when
called for a SATA device. If ata_do_eh is unable to recover
for some reason, this can result in commands that are still
outstanding when ata_do_eh returns. Change ipr to verify no
commands are outstanding before returning success.

Arrange to remove the driver-private IRQ operations and data when
the device is removed from the driver, and remove the driver
private code to do this.

This fixes potential problems caused by drivers forgetting to
remove these hooks.
