math64, tile: Fix build failure

math64, timers: Fix 32bit mul_u64_u32_shr() and friends

2017-01-14T10:31:50Z

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 headers

2011-06-03T21:36:18Z

This lets us remove a lot of one-line wrapper header files. See commit d8ecc5cd8e227bc318513b5306ae88a474b8886d for context. Signed-off-by: Chris Metcalf

arch/tile: core support for Tilera 32-bit chips.

2010-06-04T21:11:18Z

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/.
