In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.Signed-off-by: Russell King

Changes all spinlocks that can be held during an irq handler to disable
interrupts while the lock is held. Changes spin_[un]lock_irq to use the
irqsave/irqrestore variants for robustness and readability.In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're
not accessing host_info_list or host_count, and holding this lock while
trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if
ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in
raw1394.c:receive_iso. Test program attached reliably deadlocks all SMP
machines I have been able to test without this patch.Signed-off-by: Andy Wingo

- added typedef unsigned int __nocast gfp_t;
- replaced __nocast uses for gfp flags with gfp_t - it gives exactly
the same warnings as far as sparse is concerned, doesn't change
generated code (from gcc point of view we replaced unsigned int with
typedef) and documents what's going on far better.Signed-off-by: Al Viro

Set serialize_io=1 by default. This is safer and required by seemingly more

Performance of S800 1394b devices may drop by 25...30%. Therefore make the

Fixes for deadlocks of the ieee1394 and scsi subsystems and long delays in
futile error recovery attempts when SBP-2 devices are removed or drivers are
unloaded.- Complete commands quickly with DID_NO_CONNECT if the 1394 node is gone or if
the 1394 low-level driver was unloaded.
- Skip unnecessary work in the eh_abort_handler and eh_device_reset_handler if
the node or 1394 low-level driver is gone.
- Let scsi's high-level shut down gracefully when sbp2 is being unloaded or
detached from the 1394 unit. A call to scsi_remove_device is added for this
purpose, which requires us to store a scsi_device pointer.
- scsi_device pointer is obtained from slave_alloc hook and cleared by
slave_destroy. This avoids usage of the pointer after the scsi device was
deleted e.g. by the user via scsi_mod's sysfs interface.Signed-off-by: Stefan Richter

The original API returned either an ERR_PTR() or a refcounted sdev.
Unfortunately, if it's successful, you need to do a scsi_device_put() on
the sdev otherwise the refcounting is wrong.Everyone seems to expect that scsi_add_device() should be callable
without doing the ref put, so alter the API so it is (we still have
__scsi_add_device with the original behaviour).The only actual caller that needs altering is the one in firewire ...
not because it gets this right, but because it acts on the error if one
is returned.Acked-by: Stefan Richter

The pcilynx driver includes code to dump the contents of an i2c eeprom
for debugging purposes. The same can be done from userspace using the
i2cdump tool (part of the lm_sensors project) instead, in a more
efficient and flexible way.Thus I would suggest that this functionality be simply dropped from the
pcilynx driver.Signed-off-by: Jean Delvare

redundant. All SKB list removal callers know which list the
SKB is on, so storing this in sk_buff does nothing other than

irq, even if we know that our device has interrupts disabled; handler
is registered shared and taking spinlock is done unconditionally. As
it is, we can and do get oopsen on boot for some configuration, depending

Lots of this patch is trivial code cleanups (static vars were being
intialized to 0, etc).There's also some fixes for ISO transmits (max buffer handling).
Aswell, we have a few fixes to disable IRM capabilites correctly. We've
also disabled, by default some generally unused EXPORT symbols for the
sake of cleanliness in the kernel. However, instead of removing them
completely, we felt it necessary to have a config option that allowed
them to be enabled for the many projects outside of the main kernel tree
that use our API for driver development.The primary reason for this patch is to revert a MODE6->MODE10 RBC
conversion patch from the SCSI maintainers. The new conversions handled
directly in the scsi layer do not seem to work for SBP2. This patch
reverts to our old working code so that users can enjoy using Firewire
disks and dvd drives again.We are working with the SCSI maintainers to resolve this issue outside
of the main kernel tree. We'll merge the patch once the SCSI layer's
handling of the MODE10 conversion is working for us.Signed-off-by: Linus Torvalds

This patch removes CONFIG_PMAC_PBOOK (PowerBook support). This is now
split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some
powerbooks have, CONFIG_PM for power management related code, and just left
out of any CONFIG_* option for some generally useful stuff that can be used
on non-laptops as well.Signed-off-by: Benjamin Herrenschmidt

1. Establish a simple API for process freezing defined in linux/include/sched.h:
frozen(process) Check for frozen process
freezing(process) Check if a process is being frozen
freeze(process) Tell a process to freeze (go to refrigerator)
thaw_process(process) Restart process
frozen_process(process) Process is frozen now2. Remove all references to PF_FREEZE and PF_FROZEN from all
kernel sources except sched.h3. Fix numerous locations where try_to_freeze is manually done by a driver
4. Remove the argument that is no longer necessary from two function calls.
5. Some whitespace cleanup
6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
cleared before setting PF_FROZEN, recalc_sigpending does not check
PF_FROZEN).This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!Signed-off-by: Christoph Lameter

This fixed a problem that showed up in the Fedora development tree a few
weeks before the Fedora Core 4 release, initially as slab corruption, later
as hard crashes on boot up, when slab debugging was disabled for the
release. More details on the history at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a
scsi_id, without explicitly requesting space for it. Since hostdata is
declared as a zero-sized array, we don't get any such space by default, so
it must be explicitly requested. The patch below implements just that.Signed-off-by: Alexandre Oliva

drivers/ieee1394/sbp2.c: In function `sbp2_check_sbp2_response':
drivers/ieee1394/sbp2.c:2154: warning: unused variable `device_type'Signed-off-by: Andrew Morton
Signed-off-by: James Bottomley -
a) TYPE_SDAD renamed to TYPE_RBC and taken to scsi.h
b) in sbp2.c remapping of TYPE_RPB to TYPE_DISK turned off
c) relevant places in midlayer and sd.c taught to accept TYPE_RBC
d) sd.c::sd_read_cache_type() looks into page 6 when dealing with
TYPE_RBC - these guys have writeback cache flag there and are not guaranteed
to have page 8 at all.
e) sd_read_cache_type() got an extra sanity check - it checks that
it got the page it asked for before using its contents. And screams if
mismatch had happened. Rationale: there are broken devices out there that
are "helpful" enough to go for "I don't have a page you've asked for, here,
have another one". For example, PL3507 had been caught doing just that...
f) sbp2 sets sdev->use_10_for_rw and sdev->use_10_for_ms instead
of bothering to remap READ6/WRITE6/MOD_SENSE, so most of the conversions
in there are gone now.Incidentally, I wonder if USB storage devices that have no
mode page 8 are simply RBC ones. I haven't touched that, but it might
be interesting to check...Signed-off-by: Al Viro
