This avoids the whole #ifdef mess by just getting a copy of
dentry->d_inode before d_delete is called - that makes the codepaths the
same for the INOTIFY/DNOTIFY cases as for the regular no-notify case.

In yenta_socket, we default to using the resource setting of the CardBus
bridge. However, this is a PCI-bus-centric view of resources and thus needs
to be converted to generic resources first. Therefore, add a call to
pcibios_bus_to_resource() call in between. This function is a mere wrapper on
x86 and friends, however on some others it already exists, is added in this
patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where
is its pcibios_resource_to_bus() ?).

Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration
(including BARs) when transitioning from D3hot->D0. This leaves such
a device in an inaccessible state. The patch below causes the BARs
to be restored when enabling such a device, so that its driver will
be able to access it.
The patch also adds pci_restore_bars as a new global symbol, and adds a
correpsonding EXPORT_SYMBOL_GPL for that.
Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a
(re)boot. Most drivers call pci_enable_device very early, so devices
left in D3hot that lose configuration during the D3hot->D0 transition
will be inaccessible to their drivers.
Drivers could be modified to account for this, but it would
be difficult to know which drivers need modification. This is
especially true since often many devices are covered by the same
driver. It likely would be necessary to replicate code across dozens
of drivers.
The patch below should trigger only when transitioning from D3hot->D0
(or at boot), and only for devices that have the "no soft reset" bit
cleared in the PM control register. I believe it is safe to include
this patch as part of the PCI infrastructure.
The cleanest implementation of pci_restore_bars was to call
pci_update_resource. Unfortunately, that does not currently exist
for the sparc64 architecture. The patch below includes a null
implemenation of pci_update_resource for sparc64.
Some have expressed interest in making general use of the the
pci_restore_bars function, so that has been exported to GPL licensed
modules.

Current acpi_register_gsi() function has no way to indicate errors to its
callers even though acpi_register_gsi() can fail to register gsi because of
some reasons (out of memory, lack of interrupt vectors, incorrect BIOS, and so
on). As a result, caller of acpi_register_gsi() cannot handle the case that
acpi_register_gsi() fails. I think failure of acpi_register_gsi() should be
handled properly.
This series of patches changes acpi_register_gsi() to return negative value on
error, and also changes callers of acpi_register_gsi() to handle failure of
acpi_register_gsi().
This patch changes the type of return value of acpi_register_gsi() from
"unsigned int" to "int" to indicate an error. If acpi_register_gsi() fails to
register gsi, it returns negative value.

This parameter is important only to people who take the time to tune the

just in case anyone should want to do this, it's appropriate to include

I don't do anything with it in DV by design, so the parameter will come
up as off by default, so if anyone actually wants to play with the
margin control settings they'll have to enable it under the
spi_transport class first.

Checking pte_dirty instead of pte_write in __follow_page is problematic
for s390, and for copy_one_pte which leaves dirty when clearing write.
So revert __follow_page to check pte_write as before, and make
do_wp_page pass back a special extra VM_FAULT_WRITE bit to say it has
done its full job: once get_user_pages receives this value, it no longer
requires pte_write in __follow_page.
But most callers of handle_mm_fault, in the various architectures, have
switch statements which do not expect this new case. To avoid changing
them all in a hurry, make an inline wrapper function (using the old
name) that masks off the new bit, and use the extended interface with
double underscores.
Yes, we do have a call to do_wp_page from do_swap_page, but no need to
change that: in rare case it's needed, another do_wp_page will follow.

There is a number of x86 laptops that have some non-PCI IO ports
in the 0x1000-0x1fff range, and it's quite hard to control the correct
order of resource allocation between PCI and other subsystems controlling
these ports. Especially with modular kernel.
So just increase PCIBIOS_MIN_IO to 0x4000 to prevent any new PCI
resource allocations in the problematic range (this limitation must
apply _only_ to the root bus resources - see Linus' change in
pci_bus_alloc_resource). As PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO
are the same now on i386 and x86-64, we can remove the latter.

- BTTV does generate some Unimplemented IOCTL log at tuner module:
0x40046d11(dir=1,tp=0x6d,nr=17,sz=4) means that it is sending
MSP3400 calls to non-msp3400 tuners. Warning eliminated.

Implemented support to ignore an attempt to install/load
a particular ACPI table more than once. Apparently there
exists BIOS code that repeatedly attempts to load the same
SSDT upon certain events. Thanks to Venkatesh Pallipadi.
Restructured the main interface to the AML parser in
order to correctly handle all exceptional conditions. This
will prevent leakage of the OwnerId resource and should
eliminate the AE_OWNER_ID_LIMIT exceptions seen on some
machines. Thanks to Alexey Starikovskiy.
Support for "module level code" has been disabled in this
version due to a number of issues that have appeared
on various machines. The support can be enabled by
defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem
compilation. When the issues are fully resolved, the code
will be enabled by default again.
Modified the internal functions for debug print support
to define the FunctionName parameter as a (const char *)
for compatibility with compiler built-in macros such as
__FUNCTION__, etc.

sync_tsc was using smp_call_function to ask the boot processor to report
it's tsc value. smp_call_function performs an IPI_send_allbutself which is
a broadcast ipi. There is a window during processor startup during which
the target cpu has started and before it has initialized it's interrupt
vectors so it can properly process an interrupt. Receveing an interrupt
during that window will triple fault the cpu and do other nasty things.
Why cli does not protect us from that is beyond me.
The simple fix is to match ia64 and provide a smp_call_function_single.
Which avoids the broadcast and is more efficient.
This certainly fixes the problem of getting stuck on boot which was
very easy to trigger on my SMP Hyperthreaded Xeon, and I think
it fixes it for the right reasons.

The change follows the lead of others, i.e. it is guaranteed that at least

being said, GCC4.0.0 notices that the code flow does not return anything if
