similar to: [PATCH 010/113] xen: replace callers of alloc_vm_area()/free_vm_area() with xen_ prefixed one.

Also remove unused xenbus_{,un}map_ring(), adjust types, and clean up header inclusion.

Hi Jeremy. According to your suggestion, I recreated patches for Ingo's x86.git tree. And this patch series includes Eddie's modification. Please review and forward them. (or push back to respin.) Recently the xen-ia64 community started to make efforts to merge xen/ia64 Linux to upstream. The first step is to merge up domU portion. This patchset is preliminary for xen/ia64 domU linux

When I read the blkfront.c and blkback.c, I noticed that in some places (e.g, map_frontend_page()) it uses alloc_vm_area() to allocate memory for foreign page mapping. However, in some other places, it used balloon_alloc_empty_page_range() to allocate memory for mapping. What''s the difference between these two functions? Why not just use one function like alloc_vm_area() or

Hi, Xenoprof buffers are mapped into the kernel using direct_kernel_remap_pfn_range(). I need to unmap the buffer when it is not needed anymore. However, I could not find any function that unmaps pages previously mapped with direct_kernel_remap_pfn_range(). Any suggestion on how to do this? Thanks Renato _______________________________________________ Xen-devel mailing list

Hello, I''ve mapped granted pages in a module inserted in a domU and I''m trying to get the PFN or the struct page * of these pages to map them in the user space : Mapping granted pages (that''s xensocket''s code) : if (!(x->buffer_area = alloc_vm_area(buffer_num_pages * PAGE_SIZE, NULL))) { DPRINTK("error: cannot allocate %d buffer pages\n",

Hi Folks, To build drivers externally using linux-2.6-xen-sparse/drivers/xen/util.c, I need the symbols get_vm_area and remove_vm_area exported (they were exported previously - not any more in the latest version).
