* [PATCH] ufs2: more correct work with timeEvgeniy Dushistov2007-03-16
| | | | | | | | | | | | | | | | | | | | | This patch corrects work with time in UFS2 case. 1) According to UFS2 disk layout modification/access and so on "time" should be hold in two variables one 64bit for seconds and another 32bit for nanoseconds, at now for some unknown reason we suppose that "inode time" holds in three variables 32bit for seconds, 32bit for milliseconds and 32bit for nanoseconds. 2) We set amount of nanoseconds in "VFS inode" to 0 during read, instead of getting values from "on disk inode"(this should close http://bugzilla.kernel.org/show_bug.cgi?id=7991).

* [PATCH] rm pointless dmaengine exportsDavid Brownell2007-03-16
| | | | | | | | | | | | | | | | This removes several pointless exports from drivers/dma/dmaengine.c; the dma_async_memcpy_*() functions are inlined by <linux/dmaengine.h> so those exports are inappropriate. It also moves the existing EXPORT_SYMBOL declarations next to their functions, so it's now trivial to confirm one-to-one correspondence between exports and nonstatic symbols.

* [PATCH] fix read past end of array in md/linear.cAndy Isaacson2007-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When iterating through an array, one must be careful to test one's index variable rather than another similarly-named variable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt status register for the natsemi chips is clear on read and was read unconditionally from both the interrupt and from the NAPI poll routine, meaning that if the interrupt service routine was called (for example, due to a shared interrupt) while a NAPI poll was scheduled interrupts could be missed. This patch fixes that by ensuring that the interrupt status register is only read by the interrupt handler when interrupts are enabled from the chip. It also reverts a workaround for this problem from the netpoll hook and improves the trace for interrupt events. Thanks to Sergei Shtylyov <sshtylyov@ru.mvista.com> for spotting the issue, Mark Huth <mhuth@mvista.com> for a simpler method and Simon Blake <simon@citylink.co.nz> for testing resources.

| | | | | | | | | | | | | | | | | | | | | | | | | | The natsemi drivers include functions for enabling and disabling interrupts from the chip but these are not used in all code paths. This patch changes the code paths that touch the interrupt enable register to use the functions. In all cases this adds an extra PCI read to post the operation but since none of these are in fast paths this shouldn't be too much of a problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When bonding does fail over it calls set_mac_address. When this happens as the result of another port going down, the phy_mutex that is common to both ports is held, so it deadlocks. Setting the address doesn't need to do anything that needs the phy_mutex, it already has the RTNL to protect against other admin actions. This change just disables the receiver to avoid any hardware confusion while address is changing.

* | [PATCH] sysfs: reinstate exclusion between method calls and attribute ↵Alan Stern2007-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unregistration This patch (as869) reinstates the mutual exclusion between sysfs attribute method calls and attribute unregistration. The previously-reported deadlocks have been fixed, and this exclusion is by far the simplest way to avoid races during driver unbinding. The check for orphaned read-buffers has been moved down slightly, so that the remainder of a partially-read buffer will still be available to userspace even after the attribute has been unregistered.

* | [PATCH] sysfs and driver core: add callback helper, used by SCSI and S390Alan Stern2007-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as868) adds a helper routine for device drivers that need to set up a callback to perform some action in a different process's context. This is intended for use by attribute methods that want to unregister themselves or their parent device. Attribute method calls are mutually exclusive with unregistration, so such actions cannot be taken directly. Two attribute methods are converted to use the new helper routine: one for SCSI device deletion and one for System/390 ccwgroup devices.

| * HID: zeroing of bytes in output fields is bogusJiri Kosina2007-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes bogus zeroing of unused bits in output reports, introduced in Simon's patch in commit d4ae650a. According to the specification, any sane device should not care about values of unused bits. What is worse, the zeroing is done in a way which is broken and might clear certain bits in output reports which are actually _used_ - a device that has multiple fields with one value of the size 1 bit each might serve as an example of why this is bogus - the second call of hid_output_report() would clear the first bit of report, which has already been set up previously. This patch will break LEDs on SpaceNavigator, because this device is broken and takes into account the bits which it shouldn't touch. The quirk for this particular device will be provided in a separate patch. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
| * HID: allocate hid_parser in a proper wayJiri Kosina2007-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | hid_parser is non-trivially large structure, so it should be allocated using vmalloc() to avoid unsuccessful allocations when memory fragmentation is too high. This structue has a very short life, it's destroyed as soon as the report descriptor has been completely parsed. This should be considered a temporary solution, until the hid_parser is rewritten to consume less memory during report descriptor parsing.
