The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data. Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.Signed-off-by: Al Viro

More prep work for immutable bvecs/effecient bio splitting - usage of
bi_vcnt has to be auditing, so getting rid of all the unnecessary usage
makes that easier.Plus, bio_segments() is really what this code wanted, as it respects the
current value of bi_idx.Signed-off-by: Kent Overstreet

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.Cc: Bill Pemberton

when probe a pci device, first we enable it, and disable it when
some error happened in the following process, because the power
state of the device is set to D0, and if MSI is disabled,
we will allocate irq and register gsi for this device in the enable process.In function mpt_mapresources(MPT_ADAPTER *ioc), it forgot disable the
pci device when error happened, the irq and gsi will never be released.

This driver uses PCI_CLASS_REVISION instead of PCI_REVISION_ID, so it
wasn't converted by 44c10138fd4bbc ("PCI: Change all drivers to use
pci_device->revision").In one case, it even reads PCI revision ID without using it -- that code
is now removed...Signed-off-by: Sergei Shtylyov

This represents the mass deletion of the of the tokenring support.
It gets rid of:
- the net/tr.c which the drivers depended on
- the drivers/net component
- the Kbuild infrastructure around it
- any tokenring related CONFIG_ settings in any defconfigs
- the tokenring headers in the include/linux dir
- the firmware associated with the tokenring drivers.

Using strlcpy instead of memcpy makes the strlen() calls superfluous
and also ensures zero-termination of the copied string.
At the same time get rid of the magic constant 50.Actually, I can't see why copying the callback name is necessary
instead of simply storing a pointer to it (just like to the callback
function itself), but that goes beyond the scope of this fix.Signed-off-by: Ferenc Wagner

[Resend patch as per Bernd Schubert comment ]
Issue:
Device goes offline while doing aggressive HBA reset
along with IO using some utility.Root cause:
FW goes into bad state due to aggressive reset. Softreset does not
help to recover FW. And also aggressive reset open up the window for
Error handling thread to kicked off at the same time HBA will be in
constant RESET loop as part of aggressive reset test case can lead
Device to goes offline.Changes:
1. Added extra check as below inside eh_timed_out call back as below.
if(ioc->ioc_reset_in_progress) Rc = EH_TIMER_RESET2. Removed " DOORBELL_ACTIVE" check for SAS controller from task
management context. Since SAS controller uses high priority queue
for task management. This check is not required for SAS controller.3. Moved SoftReset call to HardReset from Task Mgmt context.

There's a branch at the end of this function that
is supposed to normalize the return value with what
the mid-layer expects. In this one case, we get it wrong.Also increase the verbosity of the INFO level printk
at the end of mptscsih_abort to include the actual return value
and the scmd->serial_number. The reason being success
or failure is actually determined by the state of
the internal tag list when a TMF is issued, and not the
return value of the TMF cmd. The serial_number is also
used in this decision, thus it's useful to know for debugging
purposes.Cc: stable@kernel.org
