2011-07-25xen/balloon: memory hotplug support for Xen balloon driverDaniel Kiper
Memory hotplug support for Xen balloon driver. It should be mentioned that hotplugged memory is not onlined automatically. It should be onlined by user through standard sysfs interface. Memory could be hotplugged in following steps: 1) dom0: xl mem-max <domU> <maxmem> where <maxmem> is >= requested memory size, 2) dom0: xl mem-set <domU> <memory> where <memory> is requested memory size; alternatively memory could be added by writing proper value to /sys/devices/system/xen_memory/xen_memory0/target or /sys/devices/system/xen_memory/xen_memory0/target_kb on dumU, 3) domU: for i in /sys/devices/system/memory/memory*/state; do \ [ "`cat "$i"`" = offline ] && echo online > "$i"; done Memory could be onlined automatically on domU by adding following line to udev rules: SUBSYSTEM=="memory", ACTION=="add", RUN+="/bin/sh -c '[ -f /sys$devpath/state ] && echo online > /sys$devpath/state'" In that case step 3 should be omitted.

registered Since commit a19a6ee "backlight: Allow properties to be passed at registration" and commit bb7ca74 "backlight: add backlight type", we can set backlight type and max_brightness before backlights are registered.

2011-07-24[S390] dasd: add enhanced DASD statistics interfaceStefan Weinhuber
This patch extends the DASD statistics to allow for a more detailed analysis of DASD I/O operations. In particular we want the statistics to provide answers to the following questions: - How many requests used a PAV alias? - How many requests used High Performance FICON? - How do read request perform versus write requests? The existing DASD statistics interface has several shortcomings - The interface for global data is a formatted text table in procfs (/proc/dasd/statistics). The layout is meant for human readers and is not to easy to parse. If values get to large for the table layout, they get scaled down. - The statistics which are collected per block device can be accessed via an ioctl interface, which can only be extended by defining a new ioctl. - There is no statistics interface for individual PAV base and alias devices. To overcome theses shortcomings we create a new DASD statistics interface in debugfs. This interface will contain one entry for global data, one per DASD block device, and one per DASD base and alias device. Each file contains the statistic data in easy to parse name/value and name/array pairs. The existing interfaces will remain functional, but they will not be extended.

2011-07-24[S390] qdio: clear shared DSCI before scheduling the queue handlerJan Glauber
The following race can occur with qdio devices that use the shared device state change indicator: Device (Shared DSCI) CPU0 CPU1 =============================================================================== 1. DSCI 0 => 1, INT pending 2. Thinint handler * si_used = 1 * Inbound tasklet_schedule * DSCI 1 => 0 3. DSCI 0 => 1, INT pending 4. Thinint handler * si_used = 1 * Inbound tasklet_schedu le => NOP 5. Inbound tasklet run 6. DSCI = 1, INT surpressed 7. DSCI 1 => 0 The race would lead to a stall where new data in the input queue is not recognized so the device stops working in case of no further traffic. Fix the race by resetting the DSCI before scheduling the inbound tasklet so the device generates an interrupt if new data arrives in the above scenario in step 6.

2011-07-23libata: leave port thawed after reset failureTejun Heo
libata EH intentionally left a port frozen if it failed ata_eh_reset(). The intention was avoiding continuous loop of resets when the controller or attached device is flaky and reporting spurious hotplug events. Once port enters this state, it can be recovered with manual rescan, which seemed reasonable. However, outside of my convoluted test setup, there have been very few reports justifying this choice while there have been more cases where the automatic freezing of the port after hotplug attempt of a faulty device caused confusion and led to unnecessary resets. This patch changes the behavior so that the port is thawed after reset failure. This change doesn't necessarily solve but makes it easier and more intuitive to work around hotplug related problems (ie. re-pluggin or power cycling the device) as reported in the followings. https://bugzilla.kernel.org/show_bug.cgi?id=34712 http://thread.gmane.org/gmane.linux.kernel/1123265/focus=49548 Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Reartes Guillermo <rtguille@gmail.com> Reported-by: Bruce Stenning <b.stenning@indigovision.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2011-07-23ata: Convert ata_<foo>_printk(KERN_<LEVEL> to ata_<foo>_<level>Joe Perches
Saves text by removing nearly duplicated text format strings by creating ata_<foo>_printk functions and printf extension %pV. ata defconfig size shrinks ~5% (~8KB), allyesconfig ~2.5% (~13KB) Format string duplication comes from: #define ata_link_printk(link, lv, fmt, args...) do { \ if (sata_pmp_attached((link)->ap) || (link)->ap->slave_link) \ printk("%sata%u.%02u: "fmt, lv, (link)->ap->print_id, \ (link)->pmp , ##args); \ else \ printk("%sata%u: "fmt, lv, (link)->ap->print_id , ##args); \ } while(0) Coalesce long formats. $ size drivers/ata/built-in.* text data bss dec hex filename 544969 73893 116584 735446 b38d6 drivers/ata/built-in.allyesconfig.ata.o 558429 73893 117864 750186 b726a drivers/ata/built-in.allyesconfig.dev_level.o 141328 14689 4220 160237 271ed drivers/ata/built-in.defconfig.ata.o 149567 14689 4220 168476 2921c drivers/ata/built-in.defconfig.dev_level.o Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
