2008-07-28PCI: fix bogus "'device' may be used uninitialized" warning in pci_slotMatthew Wilcox
I get warnings about 'device' possibly being used uninitialised. While I can deduce this is not true, it seems that GCC can't. This patch changes `check_slot' to return device on success and -1 on error, which shuts GCC up.

2008-07-28PCI MSI: Don't disable MSIs if the mask bit isn't supportedMatthew Wilcox
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.

2008-07-28ACPI/CPUIDLE: prevent setting pm_idle to NULLThomas Gleixner
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.

2008-07-28ipwireless: Increase PPP outgoing queue sizeDavid Sterba
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.

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.
