CMD646 corrupts data on concurrent transfers on both channels when IDE SSD is connected to one of the channels. Setup that demonstrates this hardware bug: Ultra 5, onboard CMD646, rev 3. /dev/hda is 8GB Seagate ST38410A in MWDMA2 /dev/hdd is 32GB SSD SiliconHardDisk in MWDMA2 - When reading /dev/hdd (for example with dd or fsck), reads from /dev/hda are corrupted, there are twiddled single bits 1->0 and some full 32-bit words corrupted, sometimes commands fail (which switches /dev/hda to PIO mode but the corruptions happen even in PIO). - Reads from /dev/hdd don't seem to be corrupted (i.e. fsck passes fine). - When I connected normal rotating harddisk to /dev/hdd, there was no corruption, so the corruption is something specific to SSD. - I tried the same setup on a PCI card with CMD649 and saw no corruption. This patch serializes the operation for CMD646 and 643 (I didn't test CMD643 but it may have the same hw bug too because it's earlier design). CMD649 is good. I don't know anything about CMD 648.

This reverts commit 24df31ac. The root cause of reported system hangs was (now fixed) sis5513 bug and not "ide: try to use PIO Mode 0 during probe if possible" change (commit 60293364) so the revert was incorrect (it simply replaced one regression with the other one). Signed-off-by:

Clear prefetch setting before potentially (re-)enabling it in config_drive_art_rwp() so the transition of the device type on the port from ATA to ATAPI (i.e. during warm-plug operation) is handled correctly. This is a really old bug (it probably goes back to very early days of the driver) but it was only affecting warm-plug operation until the recent "ide: try to use PIO Mode 0 during probe if possible" change (commit 60293364).

On resume from suspend, the driver currently resets the logical state as if it was brought up from halt. This patch uses the dev_pm_ops.resume/restore methods to synchronize the hardware with the memorized logical state, in effect bringing back the accelerometer and backlight to the state prior to suspend. Works for both suspend to ram and hibernation. The patch has zero effect on the running state. Signed-off-by:

The ADM1023 temperature sensor supports higher resolution for its external sensor (sensitivity of 1/8 deg C). This patch makes this higher resolution available through the appropriate temperature sysfs nodes. Curiously, this functionality was available in the 2.4 kernel driver (but formatted in a less helpful manner). Cc: Jean Delvare <khali@linux-fr.org> Signed-off-by:

Enable the coretemp driver on an Intel Atom. I'm not sure if the readings are correct, however - on my 330, the driver reports values between 27 and 41 °C (with core1 being about 8°C hotter than core0, given the same load). Maybe the maximum temperature of 100 °C is wrong for Atom CPUs. Cc: Arjan van de Ven <arjan@infradead.org> Cc: Rudolf Marek <r.marek@assembler.cz> Signed-off-by:

FLEX_ARRAY_INIT(element_size, total_nr_elements) cannot determine if either parameter is valid, so flex arrays which are statically allocated with this interface can easily become corrupted or reference beyond its allocated memory. This removes FLEX_ARRAY_INIT() as a struct flex_array initializer since no initializer may perform the required checking. Instead, the array is now defined with a new interface: DEFINE_FLEX_ARRAY(name, element_size, total_nr_elements) This may be prefixed with `static' for file scope. This interface includes compile-time checking of the parameters to ensure they are valid. Since the validity of both element_size and total_nr_elements depend on FLEX_ARRAY_BASE_SIZE and FLEX_ARRAY_PART_SIZE, the kernel build will fail if either of these predefined values changes such that the array parameters are no longer valid. Since BUILD_BUG_ON() requires compile time constants, several of the static inline functions that were once local to lib/flex_array.c had to be moved to include/linux/flex_array.h. Signed-off-by:

Add a new function to the flex_array API: int flex_array_shrink(struct flex_array *fa) This function will free all unused second-level pages. Since elements are now poisoned if they are not allocated with __GFP_ZERO, it's possible to identify parts that consist solely of unused elements. flex_array_shrink() returns the number of pages freed.

Newly initialized flex_array's and/or flex_array_part's are now poisoned with a new poison value, FLEX_ARRAY_FREE. It's value is similar to POISON_FREE used in the various slab allocators, but is different to distinguish between flex array's poisoned kmem and slab allocator poisoned kmem. This will allow us to identify flex_array_part's that only contain free elements (and free them with an addition to the flex_array API). This could also be extended in the future to identify `get' uses on elements that have not been `put'. If __GFP_ZERO is passed for a part's gfp mask, the poisoning is avoided. These elements are considered to be in-use since they have been initialized. Signed-off-by:

Add a new function to the flex_array API: int flex_array_clear(struct flex_array *fa, unsigned int element_nr) This function will zero the element at element_nr in the flex_array. Although this is equivalent to using flex_array_put() and passing a pointer to zero'd memory, flex_array_clear() does not require such a pointer to memory that would most likely need to be allocated on the caller's stack which could be significantly large depending on element_size.

Previous behavior was "bottom-up" in each section from the pattern "F:" entry that matched. Now information is entered into the various lists in the "as entered" order for each matched section. This also allows the F: entry to be put anywhere in a section, not just as the last entries in the section. And a couple of improvements: Don't alphabetically sort before outputting the matched scm, status, subsystem and web sections. Ignore content after a single email address so these entries are acceptable M: name <address> whatever other comment And a fix: Make an M: entry without a name again use the name from an immediately preceding P: line if it exists.
