Hi,
In, linux-2.2.19, I can get a phyiscal address of a page frame by using
page_address(struct page * page).
But, in linux-2.4.18, the page_address() is defined as:
#define page_address(page) ((page)->virtual)
In the page structure, there is one field "void *virtual", which is said to
be the kernel virtual addrss.
I just wonder whether I can still use the page_address() function to get the
phyiscal address in linux-2.4.18? or I have to do another way?
TIA!

Randal said it would be tough to do in sed. He didn't say he didn't
understand sed. Randal understands sed quite well. Which is why he
uses Perl. :-) -- Larry Wall in <7874@jpl-devvax.JPL.NASA.GOV>
