* Merge branch 'for-upstream/pvhvm' of ↵Linus Torvalds2010-08-231-2/+4
|\ | | | | | | | | | | | | | | | | git://xenbits.xensource.com/people/ianc/linux-2.6 * 'for-upstream/pvhvm' of git://xenbits.xensource.com/people/ianc/linux-2.6: xen: pvhvm: make it clearer that XEN_UNPLUG_* define bits in a bitfield xen: pvhvm: rename xen_emul_unplug=ignore to =unnnecessary xen: pvhvm: allow user to request no emulated device unplug
| * xen: pvhvm: rename xen_emul_unplug=ignore to =unnnecessaryIan Campbell2010-08-231-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is not immediately clear what this option causes to become ignored. The actual meaning is that it is not necessary to unplug the emulated devices to safely use the PV ones, even if the platform does not support the unplug protocol. (pressumably the user will only add this option if they have ensured that their domain configuration is safe). I think xen_emul_unplug=unnecessary better captures this.

* | Documentation: kernel-locking: mutex_trylock cannot be used in interrupt contextStefan Richter2010-08-201-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chapter 6 is right about mutex_trylock, but chapter 10 wasn't. This error was introduced during semaphore-to-mutex conversion of the Unreliable guide. :-) If user context which performs mutex_lock() or mutex_trylock() is preempted by interrupt context which performs mutex_trylock() on the same mutex instance, a deadlock occurs. This is because these functions do not disable local IRQs when they operate on mutex->wait_lock.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for exposing all GPIO pins as analog voltages. Though this is not an ideal use of the chip, some hardware engineers may decide that the LTC4245 meets their design requirements when studying the datasheet. The GPIO pins are sampled in round-robin fashion, meaning that a slow reader will see stale data. A userspace application can detect this, because it will get -EAGAIN when reading from a sysfs file which contains stale data. Users can choose to use this feature on a per-chip basis by using either platform data or the OF device tree (where applicable). Signed-off-by: Ira W.

In addition, eMMC v4.4 cards can support secure erase, trim and secure trim operations that are all variants of the basic erase command. SD/MMC device attributes "erase_size" and "preferred_erase_size" have been added. "erase_size" is the minimum size, in bytes, of an erase operation. For MMC, "erase_size" is the erase group size reported by the card. Note that "erase_size" does not apply to trim or secure trim operations where the minimum size is always one 512 byte sector. For SD, "erase_size" is 512 if the card is block-addressed, 0 otherwise. SD/MMC cards can erase an arbitrarily large area up to and including the whole card. When erasing a large area it may be desirable to do it in smaller chunks for three reasons: 1. A single erase command will make all other I/O on the card wait. This is not a problem if the whole card is being erased, but erasing one partition will make I/O for another partition on the same card wait for the duration of the erase - which could be a several minutes. 2. To be able to inform the user of erase progress. 3. The erase timeout becomes too large to be very useful. Because the erase timeout contains a margin which is multiplied by the size of the erase area, the value can end up being several minutes for large areas. "erase_size" is not the most efficient unit to erase (especially for SD where it is just one sector), hence "preferred_erase_size" provides a good chunk size for erasing large areas. For MMC, "preferred_erase_size" is the high-capacity erase size if a card specifies one, otherwise it is based on the capacity of the card. For SD, "preferred_erase_size" is the allocation unit size specified by the card. "preferred_erase_size" is in bytes.

* | | | | panic: keep blinking in spite of long spin timer modeTAMUKI Shoichi2010-08-111-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To keep panic_timeout accuracy when running under a hypervisor, the current implementation only spins on long time (1 second) calls to mdelay. That brings a good effect, but the problem is the keyboard LEDs don't blink at all on that situation. This patch changes to call to panic_blink_enter() between every mdelay and keeps blinking in spite of long spin timer mode. The time to call to mdelay is now 100ms. Even this change will keep panic_timeout accuracy enough when running under a hypervisor.

So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.
