net/hyperv: Remove unnecessary kmap_atomic in netvsc driver
__get_free_pages() doesn't return HI memory, so the memory is always mapped. kmap_atomic() is not necessary here. This patch removes the kmap_atomic() calls and related code for locking and page manipulation. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: K. Y. Srinivasan <kys@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
