Jeff Garzik 9010eff0ea [IA64] minor irq handler cleanups
- remove unused 'irq' argument from pfm_do_interrupt_handler()

- remove pointless cast to void*

- add KERN_xxx prefix to printk()

- remove braces around singleton C statement

- in tioce_provider.c, start tioce_dma_consistent() and
  tioce_error_intr_handler() function declarations in column 0

This change's main purpose is to prepare for the patchset in
jgarzik/misc-2.6.git#irq-remove, that explores removal of the
never-used 'irq' argument in each interrupt handler.

Hidetoshi Seto 38477ad751 [IA64] disable interrupts on exit of ia64_trace_syscall
While testing with CONFIG_VIRT_CPU_ACCOUNTING=y, I found that
I occasionally get very huge system time in some threads.

So I dug the issue and finally noticed that it was caused
because of an interrupt which interrupt in the following window:

> [arch/ia64/kernel/entry.S: (!CONFIG_PREEMPT && CONFIG_VIRT_CPU_ACCOUNTING)]
>
> ENTRY(ia64_leave_syscall)
>    :
> (pUStk) rsm psr.i
>         cmp.eq pLvSys,p0=r0,r0          // pLvSys=1: leave from syscall
> (pUStk) cmp.eq.unc p6,p0=r0,r0          // p6 <- pUStk
> .work_processed_syscall:
>         adds r2=PT(LOADRS)+16,r12
> (pUStk) mov.m r22=ar.itc                        // fetch time at leave
>         adds r18=TI_FLAGS+IA64_TASK_SIZE,r13
>         ;;
> <<< window: from here >>>
> (p6)    ld4 r31=[r18]  // load current_thread_info()->flags
>         ld8 r19=[r2],PT(B6)-PT(LOADRS)
>         adds r3=PT(AR_BSPSTORE)+16,r12
>         ;;
>         mov r16=ar.bsp
>         ld8 r18=[r2],PT(R9)-PT(B6)

> (p6)    br.cond.spnt .work_pending_syscall
>         ;;
>         ld8 r9=[r2],PT(CR_IPSR)-PT(R9)
>         ld8 r11=[r3],PT(CR_IIP)-PT(R11)
> (pNonSys) break 0 // bug check: we shouldn't be here if pNonSys is TRUE!
>         ;;

If pUStk is true, it means we are going to return user mode, hence we fetch
ar.itc to get time at leave from system.
It seems that it is not possible to interrupt the window if pUStk is true,
because interrupts are disabled early.  And also disabling interrupt makes
sense because it is safe for referring current_thread_info()->flags.

However interrupting the window while pUStk is true was possible.
The route was:
ia64_trace_syscall
-> .work_pending_syscall_end
-> .work_processed_syscall
Only in case entering the window from this route, interrupts are enabled
during in the window even if pUStk is true.  I suppose interrupts must be
disabled here anyway if pUStk is true.
I'm not sure but afraid that what kind of bad effect were there, other
than crazy system time which I found.

FYI, there was a commit 6f6d75825d that
points out a bug at same point(exit of ia64_trace_syscall) in 2006.
It can be said that there was an another bug.

Gary Hade cb3576fa34 PCI: Include PCI domain in PCI bus names on x86/x86_64
The PCI bus names included in /proc/iomem and /proc/ioports are
of the form 'PCI Bus #XX' where XX is the bus number.  This patch
changes the naming to 'PCI Bus XXXX:YY' where XXXX is the domain
number and YY is the bus number.  For example, PCI bus 14 in
domain 0 will show as 'PCI Bus 0000:14' instead of 'PCI Bus #14'.
This change makes the naming consistent with other architectures
such as ia64 where multiple PCI domain support has been around
longer.

Greg Kroah-Hartman 6355f3d1c6 PCI: remove pcibios_fixup_ghosts()
This function was obviously never being used since early 2.5 days as any
device that it would try to remove would never really be removed from
the system due to the PCI device list being held in the driver core, not
the general list of PCI devices.

As we have not had a single report of a problem here in 4 years, I think
it's safe to remove now.

This lets us check if the device is really added to the driver core or

is there in anticipation of getting rid of the other PCI device list,
which is what we used to check in this situation.

Greg Kroah-Hartman 1ba6ab11d8 PCI: remove initial bios sort of PCI devices on x86
We currently keep 2 lists of PCI devices in the system, one in the
driver core, and one all on its own.  This second list is sorted at boot
time, in "BIOS" order, to try to remain compatible with older kernels
(2.2 and earlier days).  There was also a "nosort" option to turn this
sorting off, to remain compatible with even older kernel versions, but
that just ends up being what we have been doing from 2.5 days...

Unfortunately, the second list of devices is not really ever used to 
determine the probing order of PCI devices or drivers[1].  That is done
using the driver core list instead.  This change happened back in the
early 2.5 days.

Relying on BIOS ording for the binding of drivers to specific device
names is problematic for many reasons, and userspace tools like udev
exist to properly name devices in a persistant manner if that is needed,
no reliance on the BIOS is needed.

Matt Domsch and others at Dell noticed this back in 2006, and added a
boot option to sort the PCI device lists (both of them) in a
breadth-first manner to help remain compatible with the 2.4 order, if
needed for any reason.  This option is not going away, as some systems
rely on them.

This patch removes the sorting of the internal PCI device list in "BIOS"
mode, as it's not needed at all anymore, and hasn't for many years.
I've also removed the PCI flags for this from some other arches that for
some reason defined them, but never used them.

This should not change the ordering of any drivers or device probing.

[1] The old-style pci_get_device and pci_find_device() still used this
sorting order, but there are very few drivers that use these functions,
as they are deprecated for use in this manner.  If for some reason, a
driver rely on the order and uses these functions, the breadth-first
boot option will resolve any problem.

Rafael J. Wysocki b844eba292 PM: Remove destroy_suspended_device()
After 2.6.24 there was a plan to make the PM core acquire all device
semaphores during a suspend/hibernation to protect itself from
concurrent operations involving device objects.  That proved to be
too heavy-handed and we found a better way to achieve the goal, but
before it happened, we had introduced the functions
device_pm_schedule_removal() and destroy_suspended_device() to allow
drivers to "safely" destroy a suspended device and we had adapted some
drivers to use them.  Now that these functions are no longer necessary,
it seems reasonable to remove them and modify their users to use the
normal device unregistration instead.

Konrad Rzeszutek 138fe4e069 Firmware: add iSCSI iBFT Support
Add /sysfs/firmware/ibft/[initiator|targetX|ethernetX] directories along with
text properties which export the the iSCSI Boot Firmware Table (iBFT)
structure.

What is iSCSI Boot Firmware Table?  It is a mechanism for the iSCSI tools to
extract from the machine NICs the iSCSI connection information so that they
can automagically mount the iSCSI share/target.  Currently the iSCSI
information is hard-coded in the initrd.  The /sysfs entries are read-only
one-name-and-value fields.

The usual set of data exposed is:

# for a in `find /sys/firmware/ibft/ -type f -print`; do  echo -n "$a: ";  cat $a; done
/sys/firmware/ibft/target0/target-name: iqn.2007.com.intel-sbx44:storage-10gb
