Subject[PATCH v5 0/2] xen: modify kernel mappings corresponding to granted pages
Hi all,
this is the fifth version of the patch "xen: modify kernel mappings
corresponding to granted pages":


changes to v4:

- add many more comments to the code;

- fix some code style issues;

- use set_page_private/page_private macros;

- compare with GNTST_general_error rather than -1;

- BUG in case map->pages are highmem;


Changes to v3:

- move the xen_mc_entry call in m2p_remove_override after the
xen_mc_flush call;

- use false rather than 0 as a parameter to alloc_xenballooned_pages;

- update the m2p_add_override call in blkback.c, following the new
interface;

- fix few code style issues.


Changes to v2:

- drop highmem support;

- fold the multicall patch into the main patch;

- add another patch to extend the alloc_xenballooned_pages interface
with an highmem parameter that allows the caller to explicitly request
for highmem or lowmem pages;

- modify gntdev to use lowmem pages only thanks to the new
alloc_xenballooned_pages interface.


Shortlog and diffstat follow:

Stefano Stabellini (2):
xen: add an "highmem" parameter to alloc_xenballooned_pages
