This is an updated patch for the sg driver that takes into
account Patrick LaVarre's fix for negative reserved buffer
sizes found in lk 2.6.0-test9.

So it has the same changelog to the patch I sent on 2003/10/11:
     - add "struct cdev" [char_devs] objects to increase
       maximum number of sg devices from 256 to 8192
     - use seq_file interface for /proc/scsi/sg/*
       pseudo files
     - sysfs symlinks between the sysfs scsi device and the
       corresponding sg cdev node (and vice versa)

An edited "tree" output showing an example of these symlinks
was included in my previous post.

As noted in another thread, st (and osst) may need "cdevs"
and sysfs symlinks so SCSI tape devices have sysfs visibility
in lk 2.6 .

Also if both st and sg had sysfs visibility then Patrick
Mansfield's scsi_id program could be made to work for tape
drives (enclosures, tape robots, etc) by following these
symlinks.

I propose the 2.6.0-test8 two-line patch below to teach
SG_SET_RESERVED_SIZE to reject a negative size, rather than oops-ing.

This patch removes the delay in calling device_del on the sdev struct
device during a surprise removal event. Reference counting functions for
sd's scsi_disk structure where also added to fix issues of unregistering
when a sd is open.

I have tested this patch using scsi_debug with differnt combinations of
adds / removes. I mounted both partitioned and un-partitioned sd disks,
remove the host, and then did a umount. The ref count debug output shows
the objects staying in place prior to the umount and cleaning up once
the umount is called.

This patch fixes an issue with a delayed call of device_del on the
sdev_gendev struct device.
	- Remove the delayed call to device_del.
	- Add kobject to sd scsi_disk structure.
	- Add release function for scsi_disk kobject.
	- Add get / put functions for scsi_disk and calls to these
	  functions.

Re-roll of the patch against 2.6.0-test6 to allow overriding or setting of
mode sense related flags, includes Alan Stern's as95 patch minus his
scsiglue.c changes.

Moves scsi_devinfo.h for use outside of drivers/scsi, and adds three new
devinfo flags:

	BLIST_MS_SKIP_PAGE_08
	BLIST_MS_SKIP_PAGE_3F
	BLIST_USE_10_BYTE_MS

Adds a per host template flags, and use of it in scsiglue.c. The per host
value can be overridden by a devinfo entry, the patch does not allow
scsi_default_dev_flags to override default host values.

USB mass storage and removable media (for testing mode page 3f use) were
not tested, if you have a USB storage device that still chokes on mode
sense 3f please give this a spin.

However, drivers/scsi/constants.c does know about Report Luns??
Looks like a merging problem by Andries and me sometime back.

If an upper layer driver is not loaded, and you write to a device's 
rescan attribute you will get an oops. The attached patch fixes this by 
testing if the device's driver variable is set before accessing it.

Resending the patch I sent some time ago for b44.c that nukes the
2.4 compatibility cruft as well.

I'll do one for 2.4.23pre6 ASAP, hopefully being able sync the driver fully
with the one in 2.6 (free_netdev() etc.).

Too much copy&paste in a call to pci_unmap_single.

1) Remove "#include <linux/version.h>" which was not needed and added
   bad extra compile dependencies.

2) Fix typo in module description.

3) Make card detection code cope with buggy SMC CIS entries.

* Critical bug fix: under heavy Tx stress using ZEROCOPY or TSO, if we
  ran out of Tx descriptors, we didn't calculate for the context
  descritor used as the first of the ZEROCOPY/TSO send, nor do we clean
  up the context desriptor bits in the case where the send isn't going
  to fit, where we need to undo the mappings.  This bug was introduced
  with the 5.2.16 patch set which included a workaround for a hang
  on 82544 over PCI-X.  This workaround cause the check for no-Tx-
  rosource logic to change, and this bug slipped in.

Fix harmless 64bit warnings in defxx.c

Fix some harmless integer/pointer size mismatch warnings in hp100.c
on 64bit compiles

This marks some net drivers which are clearly not 64bit (judging from
the warnings) as !64BIT.

removes a verry old debug line from the bpqethernet driver that
only fills logs.

fix for the probe function of the scc driver which now uses
an uninitialised scc struct for requesting an io region.

Finally got around to adding ethtool_ops to e100-3.0.x.  I found a bug
with get_eeprom() and it seems to work best if we add get_eeprom_len() to
the ops list.  Also moved check for offest + len < size into ethtool.c.

I was able to test [GS]EEPROM, PHYS_ID, GSTATS, GSTRINGS, and TEST, and
everything looks good.

Should I send same for 2.4?

pcnet_cs registers the network device too early.  The effect of this
is that the networking hotplug scripts are unable to bring the device
up automatically.

There are two issues:
- we were registering the net device before we finished setting up
  the device (eg, reading the MAC address.)
- we were using DEV_CONFIG_PENDING to block the net device "open"
  callback, and as we know the other methods may be called prior
  to open.

My only concern with this patch is that we set info->node.dev_name
after we register the net device, so use of cardctl during the
hotplug scripts may give unexpected results.  However, I am not
aware of anyone using cardctl to read the device name in network
hotplug scripts.

Please review and merge.  Thanks.

My earlier change broke the if_ptr assumption used by SPPP drivers.
This makes sealevel driver do if_ptr like it used to.

In 2.6.0-test6, I put in a patch which fixed sealevel driver, but broke
all the other wan devices because it got rid of one level of indirection.

This puts back the indirection, and hopefully prevents others from
misreading it the same way. The SPPP drivers expect that
netdev->priv points to device local structure whose first element
is a pointer to the ppp device. 

Patch from Horms <horms@vergenet.net>

Since both the primay and the backup sync daemon can be started in a box
at a time, we must just check if the MASTER bit is set in the sync state.

This fixes the stack end detection properly, and verifies that the
stack content printing does not overflow into the next page even
partially.

This is required especially for x86 BIOSes that misalign the stack,
together with the page access debugging that unmaps unused kernel
pages to check for valid accesses.

Architectures with special needs (eg HPPA with stacks that grow up)
can override the kernel stack end test with __HAVE_ARCH_KSTACK_END
if they ever enable the anal slab debugging code.

This is the minimal change to make "mlockall()" not complain about
the occasional PROT_NONE area.

PROT_NONE is commonly used on x86-64, and is no reason to not lock
in the rest of the mappings into memory.
