Hi,

	Please consider applying, no need to restore_flags here, as it is
restored in the beginning of this if block.

Err, according tho wise ppl on this list, this does not work on
MIPSes. The flags thing must stay in the same stackframe.

(I know, not your fault, but since you are patching the driver...)

yap, know that, just thought that this beast was only for i386, will submit
another patch, and I think that some other drivers does this as well...

The above doesn't work on some architectures.  Its better to use a macro
if you want to separate this out.  ie, something like (davem will have to
okay it tho):

#define DvcEnterCritical()				\
 ({ unsigned long __flags; save_flags(__flags); cli(); __flags; })

#define DvcLeaveCritical(flags)				\
 do { restore_flags(flags); } while (0)

This should then ensure that you don't end up with problems associated
with register windows on the sparc or whatever.  Even better would be
to use a spinlock instead of Dvc?????Critical.
