The ACPI FADT table includes an ASPM control bit. If the bit is set, do
not enable ASPM since it may indicate that the platform doesn't actually
support the feature.

David Vrabel has a device which generates an interrupt storm on the INTx
pin if we disable MSI interrupts altogether. Masking interrupts is only
a performance optimisation, so we can ignore the request to mask the
interrupt.

If the kernel is configured to support 64-bit resources on a 32-bit
machine, we can support 64-bit BARs properly. Just change the condition
to check sizeof(resource_size_t) instead of BITS_PER_LONG.

Factor out the code to read one BAR from the loop in pci_read_bases into
a new function, __pci_read_base. The new code is slightly more
readable, better commented and removes the ifdef.

pm_idle_save resp. pm_idle_old can be NULL when the restore code in
acpi_processor_cst_has_changed() resp. cpuidle_uninstall_idle_handler()
is called. This can set pm_idle unconditinally to NULL, which causes the
kernel to panic when calling pm_idle in the x86 idle code. This was
covered by an extra check for !pm_idle in the x86 idle code, which was
removed during the x86 idle code refactoring.
Instead of restoring the pm_idle check in the x86 code prevent the
acpi/cpuidle code to set pm_idle to NULL.

ipwireless: Increase PPP outgoing queue size
Increase default size of PPP outgoing queue. Currently set to 1, which
means that a packet quickly following another pushed by PPP must wait
until hardware actually sends the previous and PPP has to be waken up
by ppp_wakeup(). This slows down upstream.
Now PPP can push more packets at once which get buffered inside driver
and pushed immediatelly to hardware when previous packet is out.
Experiments show that size = 10 is quite good for all connection types
(GPRS/EDGE/UMTS) and gains 4 KB/sec of upload for UMTS for batch uploads.
Need for higher queue size than 10 occures in only < 0.1 % of cases.

Allow the platform data to specify the bus bumber that the
new I2C bus will be given. This is to allow the use of the
board registration mechanism to specify the new style of
I2C device registration which allows boards to provide a
list of attached devices.
Note, as discussed on the mailing list, we have dropped
backwards compatibility of adding an dynamic bus number
as it should not affect most boards to have the bus pinned
to 0 if they have either not specified platform data for
driver. Any board supplying platform data will automatically
have the bus_num field set to 0, and anyone who needs the
driver on a different bus number can supply platform data
to set bus_num.

The offset field of the scatterlist entry *after* the last valid scatterlist
entry was used instead of the first scatterlist entry (as was the intention
of this code).
This worked fine until the kzalloc of the sglist was replaced with kmalloc
and sg_init_table only zeroed the exact needed length. Apparently kzalloc
zeroes a bit more than is strictly necessary so the offset field was
always 0 in the past.
But now the offset field was suddenly random and this led to broken captures.
