Changes in v4: - The ring is always 4K (i.e XEN_PAGE_SIZE), so no need to map with PAGE_SIZE. This was correctly done in v2 but lost with the rebase to the "s/mfn/gfn/" series
Changes in v3: - Some changes has been moved in the series "Use correctly the Xen memory terminologies in Linux". - Add Stefano's reviewed-by --- drivers/tty/hvc/hvc_xen.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
