We forget to save the return value of the call to twl_rtc_write_u8(save_control, REG_RTC_CTRL_REG); in 'ret', making the test of 'ret < 0' dead code since 'ret' then couldn't possibly have changed since the last test just a few lines above. It also makes us not detect failures from that specific twl_rtc_write_u8() call. Signed-off-by:

Both displays on digsy_mtc board obtain their configuration from microwire EEPROMs which are connected to the SoC over GPIO lines. We need an easy way to access the EEPROMs to write the needed display configuration or to read out the currently programmed configuration. The generic eeprom_93xx46 SPI driver added by previous patch allows EEPROM access over sysfs. Using the simple driver added by this patch we provide used GPIO interface and access control description on the board for generic eeprom_93xx46 driver and spi_gpio driver. Signed-off-by:

As stated in drivers/mfd/cs5535-mfd.c, the mfd driver exposes the BARs which then make the GPIO, MFGPT, ACPI, etc. all visible to the system. So the dependencies of the MFGPT stuff have changed, and most people expect Kconfig to bring in the necessary dependencies. Without them, the module fails to load and most people don't understand why because the details of the rewrite aren't captured anywhere most people who know to look. This dependency needs to be reflected in Kconfig. Signed-off-by:

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.

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. Signed-off-by:

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.
