* math64, timers: Fix 32bit mul_u64_u32_shr() and friendsPeter Zijlstra2017-01-141-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | It turns out that while GCC-4.4 manages to generate 32x32->64 mult instructions for the 32bit mul_u64_u32_shr() code, any GCC after that fails horribly. Fix this by providing an explicit mul_u32_u32() function which can be architcture provided.

* tile: use generic-y format for one-line asm-generic headersChris Metcalf2011-06-031-1/+0
| | | | | | | This lets us remove a lot of one-line wrapper header files. See commit d8ecc5cd8e227bc318513b5306ae88a474b8886d for context. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
* arch/tile: core support for Tilera 32-bit chips.Chris Metcalf2010-06-041-0/+1
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/.
