[Openvortex-dev] Re: [ALSA - driver 0001138]: errors when installing au8820 modules

[Raymond]

The patch (diff11.diff) cause segmenation fault on my 32bit machine 
during /etc/init.d/alsasound start

http://savannah.nongnu.org/patch/?func=detailitem&item_id=3948

Do anyone know why readl() and writel() behave different in i386 
(32bits) and AMD64 (64bits) ?

#ifndef CONFIG_X86_64

#define        hwread(x,y) readl((x)+((y)>>2))
#define        hwwrite(x,y,z) writel((z),(x)+((y)>>2))

#else

#define        hwread(x,y) readl((x)+(y))
#define        hwwrite(x,y,z) writel((z),(x)+(y))

#endif
