2010-09-17hwmon: (lm95241) Replace rate sysfs attribute with update_intervalGuenter Roeck1-10/+11
update_interval is the matching attribute defined in the hwmon sysfs ABI. Use it. Signed-off-by: Guenter Roeck <[email protected]> Signed-off-by: Jean Delvare <[email protected]>

Fixed formatting (tabs and line breaks). The CHELSIO_GET_QSET_NUM device ioctl allows unprivileged users to read 4 bytes of uninitialized stack memory, because the "addr" member of the ch_reg struct declared on the stack in cxgb_extension_ioctl() is not altered or zeroed before being copied back to the user.

2010-09-17md: fix v1.x metadata update when a disk is missing.NeilBrown1-1/+3
If an array with 1.x metadata is assembled with the last disk missing, md doesn't properly record the fact that the disk was missing. This is unlikely to cause a real problem as the event count will be different to the count on the missing disk so it won't be included in the array. However it could still cause confusion. So make sure we clear all the relevant slots, not just the early ones. Signed-off-by: NeilBrown <[email protected]>
2010-09-17md: call md_update_sb even for 'external' metadata arrays.NeilBrown1-1/+1
Now that we depend on md_update_sb to clear variable bits in mddev->flags (rather than trying not to set them) it is important to always call md_update_sb when appropriate. md_check_recovery has this job but explicitly avoids it for ->external metadata arrays. This is not longer appropraite, or needed. However we do want to avoid taking the mddev lock if only MD_CHANGE_PENDING is set as that is not cleared by md_update_sb for external-metadata arrays.

2010-09-17firewire: nosy: fix build when CONFIG_FIREWIRE=NStefan Richter1-1/+1
drivers/firewire/nosy* is a stand-alone driver that does not depend on CONFIG_FIREWIRE. Hence let make descend into drivers/firewire/ also if that option is off. The stand-alone driver drivers/ieee1394/init_ohci1394_dma* will soon be moved into drivers/firewire/ too and will require the same makefile fix. Side effect: As mentioned in https://bugzilla.novell.com/show_bug.cgi?id=586172#c24 this influences the order in which either firewire-ohci or ohci1394 is going to be bound to an OHCI-1394 controller in case of a modular build of both drivers if no modprobe blacklist entries are configured. However, a user of such a setup cannot expect deterministic behavior anyway. The Kconfig help and the migration guide at ieee1394.wiki.kernel.org recommend blacklist entries when a dual IEEE 1394 stack build is being used. (The coexistence period of the two stacks is planned to end soon.) Cc: Michal Marek <[email protected]> Signed-off-by: Stefan Richter <[email protected]>

2010-09-15r8169: Handle rxfifo errors on 8168 chipsMatthew Garrett1-3/+2
The Thinkpad X100e seems to have some odd behaviour when the display is powered off - the onboard r8169 starts generating rxfifo overflow errors. The root cause of this has not yet been identified and may well be a hardware design bug on the platform, but r8169 should be more resiliant to this. This patch enables the rxfifo interrupt on 8168 devices and removes the MAC version check in the interrupt handler, and the machine no longer crashes when under network load while the screen turns off.

2010-09-15tcp: Prevent overzealous packetization by SWS logic.Alexey Kuznetsov1-2/+16
If peer uses tiny MSS (say, 75 bytes) and similarly tiny advertised window, the SWS logic will packetize to half the MSS unnecessarily. This causes problems with some embedded devices. However for large MSS devices we do want to half-MSS packetize otherwise we never get enough packets into the pipe for things like fast retransmit and recovery to work. Be careful also to handle the case where MSS > window, otherwise we'll never send until the probe timer. Reported-by: ツ Leandro Melo de Sales <[email protected]> Signed-off-by: David S.

Some pcnet_cs compatible cards require an exact 16-lines match of the ioport areas specified in CIS, but set the "iolines" value in the CIS incorrectly.

2010-09-15arch/tile: Change struct sigcontext to be more usefulChris Metcalf5-27/+36
Rather than just using pt_regs, it now contains the actual saved state explicitly, similar to pt_regs. By doing it this way, we provide a cleaner API for userspace (or equivalently, we avoid the need for libc to provide its own definition of sigcontext). While we're at it, move PT_FLAGS_xxx to where they are not visible from userspace. And always pass siginfo and mcontext to signal handlers, even if they claim they don't need it, since sometimes they actually try to use it anyway in practice.
