Yeah changing the name alone wont work
The problem is that the two functions remap_page_range and remap_pfn_range count
sizes in different units.
As a work around try this.
In drm_vm.h (or someother header file add this function definition)
---------------8<----------------8<-------------------------------------------
static inline __deprecated /* since 25 Sept 2004 -- wli */
int remap_page_range(struct vm_area_struct *vma, unsigned long uvaddr,
unsigned long paddr, unsigned long size, pgprot_t prot)
{
return remap_pfn_range(vma, uvaddr, paddr >> PAGE_SHIFT, size, prot);
}
---------------8<-----------------8<------------------------------------------
This is only a temporary work around and might not compile in older kernels that
already have the definition of remap_page_range. I am putting it here because
it worked for me (savage on linux 2.6.10-rc1-mm2)
A cleaner solution would be to eliminate usage of remap_page_range but I am not
sure of backward compat.
Best of luck
