Hi,
I need to reserve the pages of main memory even in my driver. If i use PG_reserved flag also the pages some time get's swapped out and my hardware is hanging . This is in kernel 2.2.x I am allocating pages by get_free_pages(..).
This is working fine in 2.3.99-pre1 if i set PG_reserved bit and ioremapping again.
How can i acheive the same in version 2.2.x.
Where can i find a documentation on using these flags. mm.h does not explain it completely??
