```
    
mdelay(1) (i.e. udelay(1000)) does not work correctly due to overflow.
    
1000 * 0x004189374BC6A7f0 = 0x10000000000000180 (>= 2**64)
    
0x004189374BC6A7ef (0x004189374BC6A7f0 - 1) is OK and it is exactly
same as catchall case (0x8000000000000000UL / (500000 / HZ)).

used_dsp was meant to be used like used_math - but since the FPU context
is small and lazy context switching is a stupid idea on multiprocessors
this idea only got halfway implemented and those bits are were now
breaking ptrace.

- [PATCH] rcu: don't set ->next_pending in rcu_start_batch() · dbc1651f
  Oleg Nesterov authored Jan 08, 2006
```
I think it is better to set ->next_pending in the caller, when
it is needed. This saves one parameter, and this coincides with
cpu_quiet() beahaviour, which sets ->completed = ->cur itself.

The patch changes semaphores that are initialized as
locked to complete().

The following patch is from Montavista.  I modified it slightly.
Semaphores are currently being used where it makes more sense for
completions.  This patch corrects that.

[PATCH] mutex subsystem, semaphore to mutex: XFS · 794ee1ba

Jes Sorensen authored Jan 09, 2006

This patch switches XFS over to use the new mutex code directly as
opposed to the previous workaround patch I posted earlier that avoided
the namespace clash by forcing it back to semaphores. This falls in the
'works for me<tm>' category.

[PATCH] mutex subsystem, add default include/asm-*/mutex.h files · 2acbb8c6

Arjan van de Ven authored Jan 09, 2006

add the per-arch mutex.h files for the remaining architectures.

We default to asm-generic/mutex-dec.h, because that performs
quite well on most arches. Arches that do not have atomic
decrement/increment instructions should switch to mutex-xchg.h
instead. Arches can also provide their own implementation for
the mutex fastpath primitives.

[PATCH] mutex subsystem, add asm-generic/mutex-[dec|xchg|null].h implementations · 620a6fd1

Ingo Molnar authored Jan 09, 2006

Add three (generic) mutex fastpath implementations.

The mutex-xchg.h implementation is atomic_xchg() based, and should
work fine on every architecture.

The mutex-dec.h implementation is atomic_dec_return() based - this
one too should work on every architecture, but might not perform the
most optimally on architectures that have no atomic-dec/inc instructions.

The mutex-null.h implementation forces all calls into the slowpath. This
is used for mutex debugging, but it can also be used on platforms that do
not want (or need) a fastpath at all.
