It's really not right to use 'access_ok()', since that is meant for the normal "get_user()" and "copy_from/to_user()" accesses, which are done through the TLB, rather than through the page tables. Why? access_ok() does both too few, and too many checks. Too many, because it is meant for regular kernel accesses that will not honor the 'user' bit in the page tables, and because it honors the USER_DS vs KERNEL_DS distinction that we shouldn't care about in GUP. And too few, because it doesn't do the 'canonical' check on the address on x86-64, since the TLB will do that for us. So instead of using a function that isn't meant for this, and does something else and much more complicated, just do the real rules: we don't want the range to overflow, and on x86-64, we want it to be a canonical low address (on 32-bit, all addresses are canonical).

With 2.6.30, the error handling code in cdrom_newpc_intr was changed to deal with partial request failures by normally completing the 'good' parts of a request and only 'error' the last (and presumably, incompletely transferred) bio associated with a particular request. In order to do this, ide_complete_rq is called over ide_cd_error_cmd() to partially complete the rq. The block layer does partial completion only for requests with bio's and if the rq doesn't have one (eg 'GPCMD_READ_DISC_INFO') the request is completed as a whole and the drive->hwif->rq pointer set to NULL afterwards. When calling ide_complete_rq again to report the error, this null pointer is derefenced, resulting in a kernel crash. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=13399. Signed-off-by:

In moxa.c there are 32 minor numbers reserved for each device. The number of ports actually available per device is stored in moxa_board_conf->numPorts. This number is not considered in moxa_open(). Opening a port that is not available results in a kernel oops. This patch adds a test to moxa_open() that prevents opening unavailable ports.

The bug is ancient. If we trace the sub-thread of our natural child and this sub-thread exits, we update parent->signal->cxxx fields. But we should not do this until the whole thread-group exits, otherwise we account this thread (and all other live threads) twice. Add the task_detached() check. No need to check thread_group_empty(), wait_consider_task()->delay_group_leader() already did this. Signed-off-by:

The rtc_update_irq() might be called with irqs enabled, if a interrupt handler was registered without IRQF_DISABLED. Use spin_lock_irqsave/spin_unlock_irqrestore instead of spin_lock/spin_unlock. Also update kerneldoc and drivers which do extra work to follow the current interface spec, as suggestted by David Brownell. Signed-off-by:

Since we renamed the file, we might want to rename the file internals too. Though we don't bother with changing platform driver name and platform module alias. The stuff is legacy and hopefully we'll remove it soon. Suggested-by:

mpc83xx_spi_work() is quite large, with up to five indentation levels and is quite difficult to read. So, split the function in two parts: 1. mpc83xx_spi_work() now only traverse queued spi messages; 2. mpc83xx_spi_do_one_msg() only manages single messages. There should be no functional changes.

When a platform is running at high frequencies it's not always possible to scale-down a frequency to a requested value, and using mmc_spi driver this leads to the following printk flood during card polling: ... mmc_spi spi32766.0: Requested speed is too low: 400000 Hz. Will use 520828 Hz instead. mmc_spi spi32766.0: Requested speed is too low: 400000 Hz. Will use 520828 Hz instead. ... Fix this by using WARN_ONCE(), it's better than the flood, and also better than turning dev_err() into dev_dbg(), since we actually want to warn that some things may not work correctly.

With this patch we'll able to select spi_mpc83xx driver on the MPC86xx platforms. Let the driver depend on FSL_SOC, so we don't have to worry about Kconfig anymore. Also remove the "experimental" dependency, the driver has been tested to work on a various hardware, and surely not experimental anymore. Signed-off-by:
