2010-10-30audit: Call tty_audit_push_task() outside preempt disabledThomas Gleixner
While auditing all tasklist_lock read_lock sites I stumbled over the following call chain: audit_prepare_user_tty() read_lock(&tasklist_lock); tty_audit_push_task(); mutex_lock(&buf->mutex); --> buf->mutex is locked with preemption disabled. Solve this by acquiring a reference to the task struct under rcu_read_lock and call tty_audit_push_task outside of the preempt disabled region. Move all code which needs to be protected by sighand lock into tty_audit_push_task() and use lock/unlock_sighand as we do not hold tasklist_lock.

2010-10-29jump label: Add work around to i386 gcc asm goto bugSteven Rostedt
On i386 (not x86_64) early implementations of gcc would have a bug with asm goto causing it to produce code like the following: (This was noticed by Peter Zijlstra) 56 pushl 0 67 nopl jmp 0x6f popl jmp 0x8c 6f mov test je 0x8c 8c mov call *(%esp) The jump added in the asm goto skipped over the popl that matched the pushl 0, which lead up to a quick crash of the system when the jump was enabled. The nopl is defined in the asm goto () statement and when tracepoints are enabled, the nop changes to a jump to the label that was specified by the asm goto. asm goto is suppose to tell gcc that the code in the asm might jump to an external label. Here gcc obviously fails to make that work. The bug report for gcc is here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46226 The bug only appears on x86 when not compiled with -maccumulate-outgoing-args. This option is always set on x86_64 and it is also the work around for a function graph tracer i386 bug. (See commit: 746357d6a526d6da9d89a2ec645b28406e959c2e) This explains why the bug only showed up on i386 when function graph tracer was not enabled. This patch now adds a CONFIG_JUMP_LABEL option that is default off instead of using jump labels by default. When jump labels are enabled, the -maccumulate-outgoing-args will be used (causing a slightly larger kernel image on i386). This option will exist until we have a way to detect if the gcc compiler in use is safe to use on all configurations without the work around. Note, there exists such a test, but for now we will keep the enabling of jump label as a manual option. Archs that know the compiler is safe with asm goto, may choose to select JUMP_LABEL and enable it by default.

2010-10-29readv/writev: do the same MAX_RW_COUNT truncation that read/write doesLinus Torvalds
We used to protect against overflow, but rather than return an error, do what read/write does, namely to limit the total size to MAX_RW_COUNT. This is not only more consistent, but it also means that any broken low-level read/write routine that still keeps counts in 'int' can't break.

2010-10-29Add new functions for triggering inode writebackChris Mason
When btrfs is running low on metadata space, it needs to force delayed allocation pages to disk. It currently does this with a suboptimal walk of a private list of inodes with delayed allocation, and it would be much better if we used the generic flusher threads. writeback_inodes_sb_if_idle would be ideal, but it waits for the flusher thread to start IO on all the dirty pages in the FS before it returns. This adds variants of writeback_inodes_sb* that allow the caller to control how many pages get sent down. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2010-10-29mfd: Adding twl6030 mmc card detect support for MMC1kishore kadiyala
Adding card detect callback function and card detect configuration function for MMC1 Controller on OMAP4. Card detect configuration function does initial configuration of the MMC Control & PullUp-PullDown registers of Phoenix. For MMC1 Controller, card detect interrupt source is twl6030 which is non-gpio. The card detect call back function provides card present/absent status by reading MMC Control register present on twl6030. Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect, the suspend/resume initialization which was done in omap_hsmmc_gpio_init previously is moved to the probe thus making it generic for both OMAP3 & OMAP4.

2010-10-29mmc: Allow the tmio_mmc mfd driver to specify get_cd handlerArnd Hannemann
Some controllers, supported by the tmio_mmc driver do not have the card detect pin of a slot connected, so that polling needs to be used and card detection is handled by other means. This patch exposes a get_cd hook for that purpose. Signed-off-by: Arnd Hannemann <arnd@arndnet.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-10-29rtc: Add MAX8998 rtc driverJoonyoung Shim
This adds support for the RTC provided by the Maxim 8998 chip. This driver was tested on a GONI board by using the rtc-test application from the Documentation/rtc.txt.

2010-10-29mfd: Use i2c_client as an argument on MAX8998 i2c routinesJoonyoung Shim
The MAX8998 chip have regulator and rtc features. The i2c slave address of regulator and rtc is different, so needs each i2c client on i2c operation functions. Also, this patch exports i2c operation functions instead of callback to make easy to read.

2010-10-29gpio: Add bitmask to block requests to unavailable stmpe GPIOsWolfram Sang
GPIOs on these controller are multi-functional. If you decided to use some of them e.g. as input channels for the ADC, you surely don't want those pins to be reassigned as simple GPIOs (which may be triggered even from userspace via 'export'). Same for the touchscreen controller pins. Since knowledge about the hardware is needed to decide which GPIOs to reserve, let this bitmask be inside platform_data and provide some defines to assist potential users.
