* x86,mrst: Intel Medfield over-current detection patchDurgadoss R2010-12-131-0/+86
| | | | | | | | | | | | This patch enables over current detection on the Intel Medfield Platform. This driver provides sysfs interfaces to configure current thresholds. When the current being drawn on the platform exceeds the configured threshold, an interrupt is generated. This interrupt can be used to bring the current consumption down by taking necessary hardware or software actions.

* Medfield_Current_Monitoring_DriverDurgadoss R2010-12-091-0/+86
| | | | | | | | | | | | | | This is the Intel Medfield Current Monitoring Driver patch. The platform specific data required by the driver are provided by adding necessary code in arch/x86/platform/mrst/mrst.c This driver monitors the platform current usage and handles interrupts when the configured current thresholds are crossed. A detailed documentation for this, has been added in Documentation/hwmon/current_monitor. Signed-off-by: Durgadoss R <durgadoss.r@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com>

| * asus-laptop: add wimax and wwan supportCorentin Chary2010-11-241-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Asus UL30A has a 3G chip, but the radio is disabled by default. The DSDT also reference a WIMAX device, which is not present on this model. This patch adds two new files: wwan and wimax to control WWAN and WIMAX devices. It does not use rfkill, because like WLED and BLED, we don't know yet that the two ACPI functions will always control the radio, they may control only the leds on some hardware. We may add rfkill switchs later. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

As per C99 6.5.7 (3) shifting int for 32 or more bits is undefined behaviour. Indeed, if sysctl_tcp_adv_win_scale is exactly 32, space >> 32 equals space and function returns 0.

There is a boot option (noswapaccount) which can disable this feature. This makes it hard for distributors to enable the configuration option as this feature leads to a bigger memory consumption and this is a no-go for general purpose distribution kernel. On the other hand swap accounting may be very usuful for some workloads. This patch adds a new configuration option which controls the default behavior (CGROUP_MEM_RES_CTLR_SWAP_ENABLED). If the option is selected then the feature is turned on by default. It also adds a new boot parameter swapaccount[=1|0] which enhances the original noswapaccount parameter semantic by means of enable/disable logic (defaults to 1 if no value is provided to be still consistent with noswapaccount). The default behavior is unchanged (if CONFIG_CGROUP_MEM_RES_CTLR_SWAP is enabled then CONFIG_CGROUP_MEM_RES_CTLR_SWAP_ENABLED is enabled as well) Signed-off-by: Michal Hocko <mhocko@suse.cz> Acked-by: Daisuke Nishimura <nishimura@mxp.nes.nec.co.jp> Cc: Balbir Singh <balbir@linux.vnet.ibm.com> Cc: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | | led-class: always implement blinkingJohannes Berg2010-11-121-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, blinking LEDs can be awkward because it is not guaranteed that all LEDs implement blinking. The trigger that wants it to blink then needs to implement its own timer solution. Rather than require that, add led_blink_set() API that triggers can use. This function will attempt to use hw blinking, but if that fails implements a timer for it. To stop blinking again, brightness_set() also needs to be wrapped into API that will stop the software blink. As a result of this, the timer trigger becomes a very trivial one, and hopefully we can finally see triggers using blinking as well because it's always easy to use.

* | | Restrict unprivileged access to kernel syslogDan Rosenberg2010-11-121-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel syslog contains debugging information that is often useful during exploitation of other vulnerabilities, such as kernel heap addresses. Rather than futilely attempt to sanitize hundreds (or thousands) of printk statements and simultaneously cripple useful debugging functionality, it is far simpler to create an option that prevents unprivileged users from reading the syslog. This patch, loosely based on grsecurity's GRKERNSEC_DMESG, creates the dmesg_restrict sysctl. When set to "0", the default, no restrictions are enforced. When set to "1", only users with CAP_SYS_ADMIN can read the kernel syslog via dmesg(8) or other mechanisms.
