Subject: Re: alpha: half done futex implementation

Hi,

Attached is a patch to (almost) add native futex support to Alpha.

It doesn't compile...

  CC      kernel/futex.o
kernel/futex.c: In function 'do_futex':
/usr/src/linux-radeon/glisse-drm/arch/alpha/include/asm/futex.h:47:
error: invalid 'asm': operand number out of range
{standard input}: Assembler messages:
{standard input}:3722: Error: bad expression
{standard input}:3722: Error: syntax error

I can't make much sense out of that.

I changed the %4's to %3 as we don't have a %4.

Please review.

Matt Turner
