* Revert adding some arch-specific signal syscalls to <linux/syscalls.h>.Chris Metcalf2010-06-073-4/+4
| | | | | | | | | | | It turns out there is some variance on the calling conventions for these syscalls, and <asm-generic/syscalls.h> is already the mechanism used to handle this. Switch arch/tile over to using that mechanism and tweak the calling conventions for a couple of tile syscalls to match <asm-generic/syscalls.h>.

* arch/tile: core support for Tilera 32-bit chips.Chris Metcalf2010-06-0434-0/+24545
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/.
