A large series adding wrappers for our interrupt handlers, so that irq/nmi/user
tracking can be isolated in the wrappers rather than spread in each handler.
Conversion of the 32-bit syscall handling into C.
A series from Nick to streamline our TLB flushing when using the Radix MMU.
Switch to using queued spinlocks by default for 64-bit server CPUs.
A rework of our PCI probing so that it happens later in boot, when more generic
infrastructure is available.
Two small fixes to allow 32-bit little-endian processes to run on 64-bit
kernels.
Other smaller features, fixes & cleanups.
