* alpha: fix __arch_hweight32 typoMatt Turner2010-06-15
| | | | | | | Typo in 1527bc8b928dd1399c3d3467dd47d9ede210978a renamed hweight32 to __arch_weight32. Signed-off-by: Matt Turner <mattst88@gmail.com>
* alpha: simplify and optimize sched_find_first_bitMatt Turner2010-05-25
| | | | | | | | | | | | | Search only the first 100 bits instead of 140, saving a couple instructions. The resulting code is about 1/3 faster (40K ticks/1000 iterations down to 30K ticks/1000 iterations).

* bitops: Optimize hweight() by making use of compile-time evaluationPeter Zijlstra2010-04-06
| | | | | | | | | | | | | Rename the extisting runtime hweight() implementations to __arch_hweight(), rename the compile-time versions to __const_hweight() and then have hweight() pick between them.

* alpha: move include/asm-alpha to arch/alpha/include/asmLinus Torvalds2008-08-15
Sam Ravnborg did the build-test that the direct header file move works, I'm just committing it. This is a pure move: mkdir arch/alpha/include git mv include/asm-alpha arch/alpha/include/asm with no other changes.
