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.

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.

mmc: sdio: avoid spurious calls to interrupt handlers

2012-06-01T07:18:26Z

commit bbbc4c4d8c5face097d695f9bf3a39647ba6b7e7 upstream. Commit 06e8935feb ("optimized SDIO IRQ handling for single irq") introduced some spurious calls to SDIO function interrupt handlers, such as when the SDIO IRQ thread is started, or the safety check performed upon a system resume. Let's add a flag to perform the optimization only when a real interrupt is signaled by the host driver and we know there is no point confirming it.

usbhid: prevent deadlock during timeout

2012-06-01T07:18:17Z

commit 8815bb09af21316aeb5f8948b24ac62181670db2 upstream. On some HCDs usb_unlink_urb() can directly call the completion handler. That limits the spinlocks that can be taken in the handler to locks not held while calling usb_unlink_urb() To prevent a race with resubmission, this patch exposes usbcore's infrastructure for blocking submission, uses it and so drops the lock without causing a race in usbhid.
