2011-07-19EHCI: fix direction handling for interrupt data togglesAlan Stern
This patch (as1480) fixes a rather obscure bug in ehci-hcd. The qh_update() routine needs to know the number and direction of the endpoint corresponding to its QH argument. The number can be taken directly from the QH data structure, but the direction isn't stored there. The direction is taken instead from the first qTD linked to the QH. However, it turns out that for interrupt transfers, qh_update() gets called before the qTDs are linked to the QH. As a result, qh_update() computes a bogus direction value, which messes up the endpoint toggle handling. Under the right combination of circumstances this causes usb_reset_endpoint() not to work correctly, which causes packets to be dropped and communications to fail. Now, it's silly for the QH structure not to have direct access to all the descriptor information for the corresponding endpoint. Ultimately it may get a pointer to the usb_host_endpoint structure; for now, adding a copy of the direction flag solves the immediate problem. This allows the Spyder2 color-calibration system (a low-speed USB device that sends all its interrupt data packets with the toggle set to 0 and hance requires constant use of usb_reset_endpoint) to work when connected through a high-speed hub. Thanks to Graeme Gill for supplying the hardware that allowed me to track down this bug.

2011-07-19ceph: fix file mode calculationSage Weil
open(2) must always include one of O_RDONLY, O_WRONLY, or O_RDWR. No need for any O_APPEND special case. Passing O_WRONLY|O_RDWR is undefined according to the man page, but the Linux VFS interprets this as O_RDWR, so we'll do the same. This fixes open(2) with flags O_RDWR|O_APPEND, which was incorrectly being translated to readonly. Reported-by: Fyodor Ustinov <ufm@ufm.su> Signed-off-by: Sage Weil <sage@newdream.net>

2011-07-19ARM: 6999/1: head, zImage: Always Enter the kernel in ARM stateDave Martin
Currently, the documented kernel entry requirements are not explicit about whether the kernel should be entered in ARM or Thumb, leading to an ambiguitity about how to enter Thumb-2 kernels. As a result, the kernel is reliant on the zImage decompressor to enter the kernel proper in the correct instruction set state. This patch changes the boot entry protocol for head.S and Image to be the same as for zImage: in all cases, the kernel is now entered in ARM. Documentation/arm/Booting is updated to reflect this new policy. A different rule will be needed for Cortex-M class CPUs as and when support for those lands in mainline, since these CPUs don't support the ARM instruction set at all: a note is added to the effect that the kernel must be entered in Thumb on such systems.

2011-07-19ARM: btc: avoid invalidating the branch target cache on kernel TLB maintanenceRussell King
Kernel space needs very little in the way of BTC maintanence as most mappings which are created and destroyed are non-executable, and so could never enter the instruction stream. The case which does warrant BTC maintanence is when a module is loaded. This creates a new executable mapping, but at that point the pages have not been initialized with code and data, so at that point they contain unpredictable information. Invalidating the BTC at this stage serves little useful purpose. Before we execute module code, we call flush_icache_range(), which deals with the BTC maintanence requirements. This ensures that we have a BTC maintanence operation before we execute code via the newly created mapping. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-07-19netfilter: nfnetlink_queue: batch verdict supportFlorian Westphal
Introduces a new nfnetlink type that applies a given verdict to all queued packets with an id <= the id in the verdict message. If a mark is provided it is applied to all matched packets. This reduces the number of verdicts that have to be sent. Applications that make use of this feature need to maintain a timeout to send a batchverdict periodically to avoid starvation.

2011-07-19netfilter: nfnetlink_queue: assert monotonic packet idsEric Dumazet
Packet identifier is currently setup in nfqnl_build_packet_message(), using one atomic_inc_return(). Problem is that since several cpus might concurrently call nfqnl_enqueue_packet() for the same queue, we can deliver packets to consumer in non monotonic way (packet N+1 being delivered after packet N) This patch moves the packet id setup from nfqnl_build_packet_message() to nfqnl_enqueue_packet() to guarantee correct delivery order. This also removes one atomic operation.

2011-07-19powerpc/pseries: Fix hvterm_raw_get_chars to accept < 16 chars, fixing xmonAnton Blanchard
commit 4d2bb3f50036 (powerpc/pseries: Re-implement HVSI as part of hvc_vio) changed udbg_getc to be based on hvterm_raw_get_chars. Unfortunately hvterm_raw_get_chars returns -EAGAIN if you ask for anything less than 16 characters. As a result xmon no longer accepts input and prints a stream of junk to the screen. The recent change highlights a problem that xmon on pseries VIO has had all along, that it can drop input characters. The issue is the hypervisor call does not take a count argument and can return up to 16 characters. This patch adds a per vterm buffer that we copy input data into and give it out as requested.
