2010-12-03iMX51: introduce IMX_GPIO_NRArnaud Patard (Rtp)
Currently, to define a GPIO number, we're using something like : #define EFIKAMX_PCBID0 (2*32 + 16) to define GPIO 3 16. This is not really readable and it's error prone imho (note the 3 vs 2). So, I'm introducing a new macro to define this in a better way. Now, the code sample become : #define EFIKAMX_PCBID0 IMX_GPIO_NR(3, 16) v2: - move to gpio.h - add parens & spaces - switch to IMX_GPIO_NR instead of MX51_GPIO_NR Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Cc: Amit Kucheria <amit.kucheria@linaro.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Eric Bénard <eric@eukrea.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2010-11-29Revert "debug_locks: set oops_in_progress if we will log messages."Dave Airlie
This reverts commit e0fdace10e75dac67d906213b780ff1b1a4cc360. On-list discussion seems to suggest that the robustness fixes for printk make this unnecessary and DaveM has also agreed in person at Kernel Summit and on list. The main problem with this code is once we hit a lockdep splat we always keep oops_in_progress set, the console layer uses oops_in_progress with KMS to decide when it should be showing the oops and not showing X, so it causes problems around suspend/resume time when a userspace resume can cause a console switch away from X, only if oops_in_progress is set (which is what we want if an oops actually is in progress, but not because we had a lockdep splat 2 days prior).

2010-11-29tpm: Autodetect itpm devicesMatthew Garrett
Some Lenovos have TPMs that require a quirk to function correctly. This can be autodetected by checking whether the device has a _HID of INTC0102. This is an invalid PNPid, and as such is discarded by the pnp layer - however it's still present in the ACPI code, so we can pull it out that way. This means that the quirk won't be automatically applied on non-ACPI systems, but without ACPI we don't have any way to identify the chip anyway so I don't think that's a great concern.

2010-11-29af_unix: limit recursion levelEric Dumazet
Its easy to eat all kernel memory and trigger NMI watchdog, using an exploit program that queues unix sockets on top of others. lkml ref : http://lkml.org/lkml/2010/11/25/8 This mechanism is used in applications, one choice we have is to have a recursion limit. Other limits might be needed as well (if we queue other types of files), since the passfd mechanism is currently limited by socket receive queue sizes only. Add a recursion_level to unix socket, allowing up to 4 levels. Each time we send an unix socket through sendfd mechanism, we copy its recursion level (plus one) to receiver. This recursion level is cleared when socket receive queue is emptied. Reported-by: Марк Коренберг <socketpair@gmail.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2010-11-29ucc_geth: fix ucc halt problem in half duplex modeYang Li
In commit 58933c64(ucc_geth: Fix the wrong the Rx/Tx FIFO size), the UCC_GETH_UTFTT_INIT is set to 512 based on the recommendation of the QE Reference Manual. But that will sometimes cause tx halt while working in half duplex mode. According to errata draft QE_GENERAL-A003(High Tx Virtual FIFO threshold size can cause UCC to halt), setting UTFTT less than [(UTFS x (M - 8)/M) - 128] will prevent this from happening (M is the minimum buffer size). The patch changes UTFTT back to 256.

2010-11-29inet: Fix __inet_inherit_port() to correctly increment bsockets and num_ownersNagendra Tomar
inet sockets corresponding to passive connections are added to the bind hash using ___inet_inherit_port(). These sockets are later removed from the bind hash using __inet_put_port(). These two functions are not exactly symmetrical. __inet_put_port() decrements hashinfo->bsockets and tb->num_owners, whereas ___inet_inherit_port() does not increment them. This results in both of these going to -ve values. This patch fixes this by calling inet_bind_hash() from ___inet_inherit_port(), which does the right thing. 'bsockets' and 'num_owners' were introduced by commit a9d8f9110d7e953c (inet: Allowing more than 64k connections and heavily optimize bind(0)) Signed-off-by: Nagendra Singh Tomar <tomer_iisc@yahoo.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Evgeniy Polyakov <zbr@ioremap.net> Signed-off-by: David S.

2010-11-29Btrfs: deal with DIO bios that span more than one ordered extentChris Mason
The new DIO bio splitting code has problems when the bio spans more than one ordered extent. This will happen as the generic DIO code merges our get_blocks calls together into a bigger single bio.

2010-11-28Export 'get_pipe_info()' to other usersLinus Torvalds
And in particular, use it in 'pipe_fcntl()'. The other pipe functions do not need to use the 'careful' version, since they are only ever called for things that are already known to be pipes. The normal read/write/ioctl functions are called through the file operations structures, so if a file isn't a pipe, they'd never get called. But pipe_fcntl() is special, and called directly from the generic fcntl code, and needs to use the same careful function that the splice code is using.

2010-11-28Rename 'pipe_info()' to 'get_pipe_info()'Linus Torvalds
.. and change it to take the 'file' pointer instead of an inode, since that's what all users want anyway. The renaming is preparatory to exporting it to other users. The old 'pipe_info()' name was too generic and is already used elsewhere, so before making the function public we need to use a more specific name.
