On one of our big machines we found a problem with posted writes while
running AIM.

Two writes of the Request Queue In pointer went out of order, making
the chip think that it had a queue wrap.

I took advantage of this opportunity to add relaxed reads, which helps
the Altix.  It should not affect other arches.  All reads are relaxed
except for the read of the Semaphore register.

Some buggy USB storage devices can return Unit Attention status for
INQUIRY commands.  The current code in scsi_scan.c checks for ASC = 0x28 =
Not ready to ready transition, but these devices can also return ASC =
0x29 = Power-on or reset occurred.  In addition, the code doesn't retry
the INQUIRY when these codes are received.

Fifth attempt at a PCMCIA SCSI driver for the Symbios 53c500
controller.  This version has all the cleanup Christoph has requested
to date, including removal of support for the obsolete (in 2.6)
proc_info functionality.

Support for additional sysfs class device attributes has been added:
two are read-only (irq, ioport), one is read-write (fast_pio).  The
read-write attribute is a per-instance flag indicating the PIO speed
of the particular HBA: valid values are 1 (enabled -- default) and 0
(disabled).

This patch was causing a boot panic.  Now fixed.

scsi_get_device needs no NULL check

drivers/scsi/sd.c: In function `scsi_disk_release':
drivers/scsi/sd.c:1477: warning: unused variable `sdev'

Move scsi_device_get out of sd probe path to allow module to be unloaded
when devices are not open.

This patch includes the following driver changes:

   1.26.00.038 - Roll driver minor version to 26 to denote kernel 2.6.
                 Add support for cmds_per_lun module parameter.
   1.26.00.039 - Fix bug in tw_chrdev_ioctl() polling code.
                 Fix data_buffer_length usage in tw_chrdev_ioctl().
                 Update contact information.

We can't refer to PCI functions for a pure
EISA machine.

This is because aic7xxx does not unregister itself properly if no devices
are found.  This patch fixes the problem.

This patch changes the st console/log messages:

- __GFP_NOWARN added to buffer allocation to suppress useless messages
  when having to use smaller than default segments
- move log message from enlarge_buffer() to caller so that the tape name
  can be printed and remove some debugging messages; now the st messages
  should include drive name where applicable (a problem reported by
  Hironobu Ishii)
- setting options is logged only when debugging; the most important
  options are now seen in sysfs

- always set_current_state(TASK_UNINTERRUBTIBLE) unless we explicitly
  check for signals.

- make all timeouts take HZ based values.

this patch kills qlogic_core.c and I guess the same idea can be
applied to other pcmcia scsi drivers. comments?

	this patch kills irq probe and also I/O because isn't useful to
	probe I/O if we can't probe irq later.

If a filesystem's ->writepage implementation repeatedly refuses to write the
page (it keeps on redirtying it instead) (reiserfs seems to do this) then the
writeback logic can get stuck repeately trying to write the same page.

Fix that up by correctly setting wbc->pages_skipped, to tell the writeback
logic that things aren't working out.

Since symlink.c uses "name" field of a kobj when it calculates the
length,  it gets a wrong value if the kobj's name  has more than 20
charathers.  A correct way to do that is to call kobject_name(kobj)
instead of using kobj->name directly.

this patch (2.4 & 2.6) fixes a bug about the timeout value. The formula
used to calculate jiffies from timeout is wrong.
The new formula is ok and takes care of integer computation/rounding.
There is the same bug in the tiglusb.c module which will be fixed by another
patch.

Handle some PL-2301/2302 devices better.

I just checked out the latest 2.6.6-rc1-mm1 to see that the ID patch for
ftdi has applied cleanly, but apparently someone was faster and in the
combined ID table our ID's were missing.
Most probably the patch program got confused and applied the hung at wrong
spot..

Attached is a patch that places that 2 lines in the correct spot.

Hi,

this patch (cumulative; 2.4 & 2.6) fixes another bug in the tiglusb
driver. The formula used to calculate jiffies from timeout is wrong.
The new formula is ok and takes care of integer computation/rounding.
This is the same kind of bug than in the tipar char driver.

Warnings aren't terribly important in and of themselves, but there
isn't really much the warning tells us to do here, so it would appear
that caving in to the compiler is the thing to do for now.

Various build fixes:  64bit (Andrew Morton), static linking,
broken on big-endian, etc.

Tighten up the integration with the main "ether" driver, so
state transitions and host ethernet addresses are shared too.
Add missing spinlock calls around RNDIS command outcall,
fix GET_INTERFACE issue, host mustn't clobber netdev flags.

Minor code cleanups.

Cope better when PCI misbehaves badly and registers misbehave:

    - terminate some loops before they get to infinity
       * capability scan
       * port reset
    - after init failure, memory may already be cleaned up

Some systems have been reporting such problems after ACPI resume.

This replaces current_thread_info()->cpu in i386' init_IRQ() by the
equivalent smp_processor_id().

Reduces overhead on UP, and makes the code cleaner.

This simplifies the Pentium M quirk code in nmi.c, and eliminates an
unnecessary apic_read().

Local APIC accesses are not zero-cycle; let's not inflict more damage
than we must.

We need some alignement of those structs for proper operations especially
with FP and Altivec, or SLAB_DEBUG can break us.

This patch just adds some proc entries for the virtual tape and cdrom
drivers to allow mapping between linux devices and OS/400 ones.  This is
expected by existing users and there is no other way to do this
translation.

Without this the task struct gets unaligned when using SLAB_DEBUG, causing

MIPS now also uses the generic ioctl compat code.
