* tile: improve big-endian supportChris Metcalf2013-08-13
| | | | | | | | | | | | First, fix a bug in asm/unaligned.h; we need to just use the asm-generic unaligned.h so we properly choose endian-correct flavors. Second, keep the hv/hypervisor.h ABI fully "native" in the sense that we don't have __BIG_ENDIAN__ ifdefs there. Instead, we use macros in the head_NN.S assembly code to properly extract two 32-bit structure members from a 64-bit register holding the structure. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>

* arch/tile: core support for Tilera 32-bit chips.Chris Metcalf2010-06-04
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/.
