[PATCH v3 2/3] ARM/dts: omap3: Add support for IGEPv2 board

ISEE IGEPv2 is an TI OMAP3 SoC based embedded board. This patch adds an initial device tree support to boot an IGEPv2 from the MMC/SD. Currently is working everything that is supported by DT on OMAP3 SoCs (MMC/SD, GPIO LEDs, EEPROM, TWL4030 audio). Signed-off-by: Javier Martinez Canillas

[PATCH Resend 0/3] sched: fix nr_busy_cpus

The nr_busy_cpus field of the sched_group_power is sometime different from 0 whereas the platform is fully idle. This serie fixes 3 use cases: - when the SCHED softirq is raised on an idle core for idle load balance but the platform doesn't go out of the cpuidle state - when some CPUs enter

[PATCH Resend 2/3] sched: fix init NOHZ_IDLE flag

On my smp platform which is made of 5 cores in 2 clusters,I have the nr_busy_cpus field of sched_group_power struct that is not null when the platform is fully idle. The root cause seems to be: During the boot sequence, some CPUs reach the idle loop and set their NOHZ_IDLE flag while waiting for

[PATCH Resend 3/3] sched: fix update NOHZ_IDLE flag

The function nohz_kick_needed modifies NOHZ_IDLE flag that is used to update the nr_busy_cpus of the sched_group. When the sched_domain are updated (because of the unplug of a CPUs as an example) a null_domain is attached to CPUs. We have to test likely(!on_null_domain(cpu) first in order to

[PATCH Resend 1/3] sched: fix nr_busy_cpus with coupled cpuidle

With the coupled cpuidle driver (but probably also with other drivers), a CPU loops in a temporary safe state while waiting for other CPUs of its cluster to be ready to enter the coupled C-state. If an IRQ or a softirq occurs, the CPU will stay in this internal loop if there is no need to resched.

[PATCH] net/macb: Use dmapool to align descriptors on 64bits
