The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

This change enables PCI root complex support for TILEPro. Unlike TILE-Gx, TILEPro has no support for memory-mapped I/O, so the PCI support consists of hypervisor upcalls for PIO, DMA, etc. However, the performance is fine for the devices we have tested with so far (1Gb Ethernet, SATA, etc.). The <asm/io.h> header was tweaked to be a little bit more aggressive about disabling attempts to map/unmap IO port space. The hacky <asm/pci-bridge.h> header was rolled into the <asm/pci.h> header and the result was simplified. Both of the latter two headers were preliminary versions not meant for release before now - oh well. There is one quirk for our TILEmpower platform, which accidentally negotiates up to 5GT and needs to be kicked down to 2.5GT. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

While not a port to KVM (yet), this change modifies the kernel to be able to build either at PL1 or at PL2 with a suitable config switch. Pushing up this change avoids handling branch merge issues going forward with the KVM work. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

This network (the "UDN") connects all the cpus on the chip in a wormhole-routed dynamic network. Subrectangles of the chip can be allocated by a "create" ioctl on /dev/hardwall, and then to access the UDN in that rectangle, tasks must perform an "activate" ioctl on that same file object after affinitizing themselves to a single cpu in the region. Sending a wormhole-routed message that tries to leave that subrectangle causes all activated tasks to receive a SIGILL (just as they would if they tried to access the UDN without first activating themselves to a hardwall rectangle). The original submission of this code to LKML had the driver instantiated under /proc/tile/hardwall. Now we just use a character device for this, conventionally /dev/hardwall. Some futures planning for the TILE-Gx chip suggests that we may want to have other types of devices that share the general model of "bind a task to a cpu, then 'activate' a file descriptor on a pseudo-device that gives access to some hardware resource". As such, we are using a device rather than, for example, a syscall, to set up and activate this code. As part of this change, the compat_ptr() declaration was fixed and used to pass the compat_ioctl argument to the normal ioctl. So far we limit compat code to 2GB, so the difference between zero-extend and sign-extend (the latter being correct, eventually) had been overlooked.

This change is the core kernel support for TILEPro and TILE64 chips. No driver support (except the console driver) is included yet. This includes the relevant Linux headers in asm/; the low-level low-level "Tile architecture" headers in arch/, which are shared with the hypervisor, etc., and are build-system agnostic; and the relevant hypervisor headers in hv/.
