2009-12-16ACPI processor: Fix section mismatch for processor_add()Thomas Renninger
Due to the merge of processor_start() (declared with __cpuinit) into processor_add(), a section mismatch warning appears: WARNING: drivers/built-in.o(.text+0x4d59d): Section mismatch in reference from the function acpi_processor_add() to the function .cpuinit.text:acpi_processor_power_init() ... This patch fixes the warning by declaring processor_add() as __cpuinit and also declares acpi_processor_add_fs() as __cpuinit as it is only used in acpi_processor_add().

2009-12-16gru: send cross partition interrupts using the gruJack Steiner
GRU Message queue instructions are used to deliver messages to other SSIs within the numalink domain. In most cases, a single GRU mesq instruction will deliver both the message AND an interrupt to notify the other SSI that a messsage is present. In some cases, however, the interrupt must be sent explicitly. To improve resilency, the GRU driver should send these explicit interrupts using the GRU to write the remote chipset register. Current code sends the interrupt using a cpu instruction to write the chipset register.
