* sdio: fix read buffer overflowRoel Kluin2009-09-231-1/+1

* sdhci: be more strict with get_min_clock() usageAnton Vorontsov2009-09-231-1/+2
| | | | | | | | | | | | | | | | | get_min_clock() makes sense only with NONSTANDARD_CLOCK quirk and when set_clock() callback is specified. The patch should cause no functional changes, it just makes the code self-documented and avoids any possible misuse of get_min_clock().

* sdio: add CD disable supportOhad Ben-Cohen2009-09-231-0/+30
| | | | | | | | | | | | | | | | | | Add support to disconnect the pull-up resistor on CD/DAT[3] (pin 1) of the card. This may be desired on certain setups of boards, controllers and embedded sdio devices which do not need the card's pull-up. As a result, card detection is disabled and power is saved.

* omap_hsmmc: set a large data timeout for commands with busy signalAdrian Hunter2009-09-231-4/+11
| | | | | | | | | | | | | | | | | | | | | | Commands like SWITCH (CMD6) send a response and then signal busy while the operation is completed. These commands are expected to always succeed (otherwise the response would have indicated an error). Set an arbitrarily large data timeout value (100ms) for these commands to ensure that premature timeouts do not occur.

* omap_hsmmc: protect the card when the cover is openAdrian Hunter2009-09-231-2/+61
| | | | | | | | | | | | | | | | | | | | Depending on the manufacturer, there is a small possibility that removing a card while it is being written to, can render the card permanently unusable. To prevent that, the card is made inaccessible when the cover is open.

* omap_hsmmc: prevent races with irq handlerAdrian Hunter2009-09-231-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | If an unexpected interrupt occurs while preparing the next request, an oops can occur. For example, a new request is setting up DMA for data transfer so host->data is not NULL. An unexpected transfer complete (TC) interrupt comes along and the interrupt handler sets host->data to NULL. Oops! Prevent that by adding a spinlock. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Acked-by: Matt Fleming <matt@console-pimps.org> Cc: Ian Molton <ian@mnementh.co.uk> Cc: "Roberto A.

| | | | | | | | | | | | | | | | | | | | | | Power can be saved by powering off cards that are not in use. This is similar to suspend / resume except it is under the control of the driver, and does not require any power management support. It can only be used when the driver can monitor whether the card is removed, otherwise it is unsafe. This is possible because, unlike suspend, the driver still receives card detect and / or cover switch interrupts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | omap_mmc_probe lives in .init.text, so using platform_driver_register to register it is wrong because binding a device after the init memory is discarded (e.g. via sysfs) results in an oops. As requested by David Brownell platform_driver_probe is used instead of moving the probe function to .devinit.text as proposed initially. This saves some memory, but devices registered after the driver is probed are not bound (probably there are none) and binding via sysfs isn't possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | gcc permitting variable length arrays makes the current construct used for BUILD_BUG_ON() useless, as that doesn't produce any diagnostic if the controlling expression isn't really constant. Instead, this patch makes it so that a bit field gets used here. Consequently, those uses where the condition isn't really constant now also need fixing. Note that in the gfp.h, kmemcheck.h, and virtio_config.h cases MAYBE_BUILD_BUG_ON() really just serves documentation purposes - even if the expression is compile time constant (__builtin_constant_p() yields true), the array is still deemed of variable length by gcc, and hence the whole expression doesn't have the intended effect.

* proc connector: add event for process becoming session leaderScott James Remnant2009-09-231-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The act of a process becoming a session leader is a useful signal to a supervising init daemon such as Upstart. While a daemon will normally do this as part of the process of becoming a daemon, it is rare for its children to do so. When the children do, it is nearly always a sign that the child should be considered detached from the parent and not supervised along with it. The poster-child example is OpenSSH; the per-login children call setsid() so that they may control the pty connected to them. If the primary daemon dies or is restarted, we do not want to consider the per-login children and want to respawn the primary daemon without killing the children. This patch adds a new PROC_SID_EVENT and associated structure to the proc_event event_data union, it arranges for this to be emitted when the special PIDTYPE_SID pid is set.
