Since TILE doesn't do read speculation, its control dependencies also guarantee LOAD->LOAD order and we don't need the additional RMB otherwise required to provide ACQUIRE semantics.

This defines __smp_xxx barriers for tile, for use by virtualization. Some smp_xxx barriers are removed as they are defined correctly by asm-generic/barriers.h Note: for 32 bit, keep smp_mb__after_atomic around since it's faster than the generic implementation.

We're going to be adding a few new barrier primitives, and in order to avoid endless duplication make more agressive use of asm-generic/barrier.h. Change the asm-generic/barrier.h such that it allows partial barrier definitions and fills out the rest with defaults. There are a few architectures (m32r, m68k) that could probably do away with their barrier.h file entirely but are kept for now due to their unconventional nop() implementation.

This chip is no longer being actively developed for (it was superceded by the TILEPro64 in 2008), and in any case the existing compiler and toolchain in the community do not support it. It's unlikely that the kernel works with TILE64 at this point as the configuration has not been tested in years. The support is also awkward as it requires maintaining a significant number of ifdefs. So, just remove it altogether. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

This avoids having to maintain an additional separate assembly file, and of course the inline is slightly more efficient as well. 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 change adds one of the Tilera standard <arch> headers to the set of headers shipped with Linux. The <arch/sim.h> header provides methods for programmatically interacting with the Tilera simulator. The current <arch/sim.h> provides inline assembly for the _sim_syscall function, so the declaration and definition previously provided manually in Linux are no longer needed. We now use the standard sim_validate_lines_evicted() method from <arch/sim.h> rather than rolling our own direct call to sim_syscall(). Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

None of these changes fix any actual bugs, but are just various cleanups that fell out along the way. In particular, some unused #defines and includes are removed, PREFETCH_STRIDE is added (the default is right for our shipping chips, but wrong for our next generation), our tile-specific prefetching code is removed so the (identical) generic prefetching code can be used instead, a comment is fixed to be proper GPL and not just a "paste GPL here" token, a "//" comment is converted to "/* */", etc. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com> Acked-by: NArnd Bergmann <arnd@arndb.de>

This commit is primarily changes caused by reviewing "sparse" and "checkpatch" output on our sources, so is somewhat noisy, since things like "printk() -> pr_err()" (or whatever) throughout the codebase tend to get tedious to read. Rather than trying to tease apart precisely which things changed due to which type of code review, this commit includes various cleanups in the code: - sparse: Add declarations in headers for globals. - sparse: Fix __user annotations. - sparse: Using gfp_t consistently instead of int. - sparse: removing functions not actually used. - checkpatch: Clean up printk() warnings by using pr_info(), etc.; also avoid partial-line printks except in bootup code. - checkpatch: Use exposed structs rather than typedefs. - checkpatch: Change some C99 comments to C89 comments. In addition, a couple of minor other changes are rolled in to this commit: - Add support for a "raise" instruction to cause SIGFPE, etc., to be raised. - Remove some compat code that is unnecessary when we fully eliminate some of the deprecated syscalls from the generic syscall ABI. - Update the tile_defconfig to reflect current config contents.

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/.
