99b7623380 proc 2/2: remove struct proc_dir_entry::owner
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.

We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.

But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.

->read_proc/->write_proc were just fixed to not require ->owner for
protection.

rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.

Removing ->owner will also make PDE smaller.

So, let's nuke it.

Kudos to Jeff Layton for reminding about this, let's say, oversight.

fe2d5ffc74 Fix platform drivers that crash on suspend/resume
It turns out that if one registers a struct platform_device, the
platform device code expects that platform_device.device->driver points
to a struct driver inside a struct platform_driver.

This is not the case with the ipmi-si, ipmi-msghandler and ibmaem
drivers, which causes the suspend/resume hook functions to jump off into
nowhere, causing a crash.  Make this assumption hold true for these
three drivers.

233e70f422 saner FASYNC handling on file close
As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.

So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set.  And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

6c89161b10 ipmi: add MODULE_ALIAS to load ipmi_devintf with ipmi_si
The ipmi_devintf module contains the userspace interface for IPMI devices,
yet will not be loaded automatically with a system interface handler
driver.

Add a MODULE_ALIAS for the "platform:ipmi_si" MODALIAS exported by the
ipmi_si driver, so that userspace knows of the recommendation.

bda4c30aa6 ipmi: run to completion fixes
The "run_to_completion" mode was somewhat broken.  Locks need to be avoided in
run_to_completion mode, and it shouldn't be used by normal users, just
internally for panic situations.

This patch removes locks in run_to_completion mode and removes the user call
for setting the mode.  The only user was the poweroff code, but it was easily
converted to use the polling interface.

out that if you try to claim a lock in a parameter handling routine, lockdep
won't see that lock as "static" yet because the module is not yet on the

However, the semaphore in question is completely unnecessary.  So just remove
it.

c45adc3915 IPMI: don't init irq until ready
Patrick found a race at startup.  Interrupts were being enabled for the IPMI
interface before the driver was really ready to handle them.  This could
result in an oops if something was pending on the interface at startup and
interrupt were already enabled (technically shouldn't happen, but need to
cover for this in real life).  So move the IRQ setup to the code that starts
the actual IPMI processing.

1855256c49 drivers/firmware: const-ify DMI API and internals
Three main sets of changes:

1) dmi_get_system_info() return value should have been marked const,
   since callers should not be changing that data.

2) const-ify DMI internals, since DMI firmware tables should,
   whenever possible, be marked const to ensure we never ever write to
   that data area.

3) const-ify DMI API, to enable marking tables const where possible
   in low-level drivers.

And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.

The bulk of the changes are #2 and #3, which are interrelated.  #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.

248bdd5efc pci: fix unterminated pci_device_id lists
Fix a couple drivers that do not correctly terminate their pci_device_id
lists.  This results in garbage being spewed into modules.pcimap when the
module happens to not have 28 NULL bytes following the table, and/or the
last PCI ID is actually truncated from the table when calculating the
modules.alias PCI aliases, cause those unfortunate device IDs to not
auto-load.
