Noticed by Roman Zippel: use cfs_rq->curr in the !group-scheduling case too. Small micro-optimization and cleanup effect: text data bss dec hex filename 36269 3482 24 39775 9b5f sched.o.before 36177 3486 24 39687 9b07 sched.o.after Signed-off-by:

continued removal of precise CPU load calculations. Signed-off-by:
-
Ingo Molnar authored
CPU load calculations are statistical anyway, and there's little benefit from having it calculated on every scheduling event. So remove this code, it gets rid of a divide from the scheduler wakeup and context-switch fastpath. Signed-off-by:

use constants if !CONFIG_SCHED_DEBUG. this speeds up the code and reduces code-size: text data bss dec hex filename 27464 3014 16 30494 771e sched.o.before 26929 3010 20 29959 7507 sched.o.after Signed-off-by: -

fix the sched_child_runs_first flag: always call into ->task_new() if we are on the same CPU, as SCHED_OTHER tasks depend on it for correct initial setup. Signed-off-by:

Make sure the mmc_spi driver can build without CONFIG_BLOCK. Issue noted by "Avuton Olrich" <avuton@gmail.com> and randconfig. While that won't be a common configuration, sometimes embedded boards use SDIO to interface WLAN or Bluetooth chips (vs some parallel interface), and don't provide an MMC/SD socket for use with flash memory cards.

The call to napi_disable() in the PCI shutdown handler is problematic, and is aggravated by the new NAPI. Also, make sure watchdog timer doesn't go off. Signed-off-by:

The 64bit SMP bootup is slightly different to the 32bit one. It enables the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E systems have the C1E feature flag only set in the secondary CPU. Due to the early enable of the boot CPU local APIC timer the APIC timer is registered as a fully functional device. When we detect the wreckage during the bringup of the secondary CPU, we need to force the boot CPU into broadcast mode. Check the C1E caused APIC timer disable, when the secondary APIC timer is initialized. If the boot CPU APIC timer was registered as a functional clock event device, then fix this up and utilize the CLOCK_EVT_NOTIFY_BROADCAST_FORCE mechanism to force the already registered boot CPU APIC timer into broadcast mode. Tested by force injecting the failure mode. Signed-off-by: -

if your mask is host-endian, you should apply it after le64_to_cpu(); if it's little-endian - before. Doing both (for the same mask and little-endian value) is broken. Signed-off-by:
