libata: add a host flag to ignore detected ATA devices

2012-06-17T18:21:29Z

commit db63a4c8115a0bb904496e1cdd3e7488e68b0d06 upstream. Where devices are visible via more than one host we sometimes wish to indicate that cirtain devices should be ignored on a specific host. Add a host flag indicating that this host wishes to ignore ATA specific devices. Signed-off-by: Andy Whitcroft Signed-off-by: Jeff Garzik Cc: Victor Miasnikov Signed-off-by: Greg Kroah-Hartman

module_param: stop double-calling parameters.

2012-06-17T18:21:23Z

commit ae82fdb1406ad41d68f07027fe31f2d35ba22a90 upstream. Commit 026cee0086fe1df4cf74691cf273062cc769617d "params: _initcall-like kernel parameters" set old-style module parameters to level 0. And we call those level 0 calls where we used to, early in start_kernel(). We also loop through the initcall levels and call the levelled module_params before the corresponding initcall. Unfortunately level 0 is early_init(), so we call the standard module_param calls twice. (Turns out most things don't care, but at least ubi.mtd does). Change the level to -1 for standard module_param calls. Reported-by: Benoît Thébaudeau Signed-off-by: Rusty Russell Signed-off-by: Greg Kroah-Hartman

radix-tree: fix contiguous iterator

2012-06-09T15:36:17Z

commit fffaee365fded09f9ebf2db19066065fa54323c3 upstream. This patch fixes bug in macro radix_tree_for_each_contig(). If radix_tree_next_slot() sees NULL in next slot it returns NULL, but following radix_tree_next_chunk() switches iterating into next chunk. As result iterating becomes non-contiguous and breaks vfs "splice" and all its users.

skb: avoid unnecessary reallocations in __skb_cow

2012-06-09T15:36:15Z

[ Upstream commit 617c8c11236716dcbda877e764b7bf37c6fd8063 ] At the beginning of __skb_cow, headroom gets set to a minimum of NET_SKB_PAD. This causes unnecessary reallocations if the buffer was not cloned and the headroom is just below NET_SKB_PAD, but still more than the amount requested by the caller. This was showing up frequently in my tests on VLAN tx, where vlan_insert_tag calls skb_cow_head(skb, VLAN_HLEN). Locally generated packets should have enough headroom, and for forward paths, we already have NET_SKB_PAD bytes of headroom, so we don't need to add any extra space here.

ipv6: fix incorrect ipsec fragment

2012-06-09T15:36:15Z

[ Upstream commit 0c1833797a5a6ec23ea9261d979aa18078720b74 ] Since commit ad0081e43a "ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed" the fragment of packets is incorrect. because tunnel mode needs IPsec headers and trailer for all fragments, while on transport mode it is sufficient to add the headers to the first fragment and the trailer to the last. so modify mtu and maxfraglen base on ipsec mode and if fragment is first or last. with my test,it work well(every fragment's size is the mtu) and does not trigger slow fragment path. Changes from v1: though optimization, mtu_prev and maxfraglen_prev can be delete. replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL. add fuction ip6_append_data_mtu to make codes clearer.

kbuild: install kernel-page-flags.h

2012-06-09T15:36:11Z

commit 9295b7a07c859a42346221b5839be0ae612333b0 upstream. Programs using /proc/kpageflags need to know about the various flags. The provides them and the comments in the file indicate that it is supposed to be used by user-level code. But the file is not installed. Install the headers and mark the unstable flags as out-of-bounds.
