Thanks to some much-appreciated volunteer work reviewing that initial patch, I now have a revised set of patches which I would like to offer for submission to the mainline. The largest chunk of work has been adopting the "generic" syscall ABI in asm-generic. It required some work extending it to a new architecture, particularly to support both 32- and 64-bit chips, and to support a 32-bit compat layer on the 64-bit architecture. Many thanks to Arnd Bergmann for working with me on this. In addition, I have wised up and removed most of the driver material from this patch. They are not immediately essential for booting up Tilera Linux, and I will plan to feed the drivers back over time after this initial baseline patch has been accepted. The patches are in eight commits, the first being the changes to the "generic" ABI. The remaining seven patches are the tile architecture code, broken up into somewhat digestible chunks. Many thanks to the folks who took the time to review parts of the initial diffs: Arnd Bergmann <arnd@xxxxxxxx> Barry Song <21cnbao@xxxxxxxxx> Sam Ravnborg <sam@xxxxxxxxxxxx> Thomas Gleixner <tglx@xxxxxxxxxxxxx> Marc Gauthier <marc@xxxxxxxxxxxxx> Jamie Lokier <jamie@xxxxxxxxxxxxx> and Linus for reviewing my one-line lowmem_page_address() patch :-) Chris Metcalf (8): Fix up the "generic" unistd.h ABI to be more useful. arch/tile: infrastructure and configuration-related files. arch/tile: header files for the Tile architecture. arch/tile: core kernel/ code. arch/tile: the kernel/tile-desc_32.c file. arch/tile: the mm/ directory. arch/tile: lib/ directory. arch/tile: hypervisor console driver.
