I haven't had a chance to pursue why yet. There is probably some arch issue I'm unaware of. bob Signed-off-by: Bob Picco <bob.picco@hp.com> include/asm-ia64/page.h | 1 + 1 files changed, 1 insertion(+) Index: linux-2.6.14-rc5-mm1/include/asm-ia64/page.h =================================================================== --- linux-2.6.14-rc5-mm1.orig/include/asm-ia64/page.h 2005-10-24 14:38:36.000000000 -0400 +++ linux-2.6.14-rc5-mm1/include/asm-ia64/page.h 2005-10-31 13:03:40.000000000 -0500 @@ -120,6 +120,7 @@ extern unsigned long max_low_pfn; #define page_to_phys(page) (page_to_pfn(page) << PAGE_SHIFT) #define virt_to_page(kaddr) pfn_to_page(__pa(kaddr) >> PAGE_SHIFT) +#define pfn_to_kaddr(pfn) __va((pfn) << PAGE_SHIFT) typedef union ia64_va { struct { - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Tue Nov 01 05:25:50 2005
