The patch titled Move vmalloc_to_page() to mm/vmalloc. has been removed from the -mm tree. Its filename was move-vmalloc_to_page-to-mm-vmalloc.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: Move vmalloc_to_page() to mm/vmalloc. From: Christoph Lameter <clameter@xxxxxxx> We already have page table manipulation for vmalloc in vmalloc.c. Move the vmalloc_to_page() function there as well. Move the definitions for vmalloc related functions in mm.h to a newly created section. A better place would be vmalloc.h but mm.h is basic and may depend on these functions. An alternative would be to include vmalloc.h in mm.h (like done for vmstat.h).
