Subject: sched: convert struct root_domain to cpumask_var_t, fix
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1c39194878c09bd88ffc9c9d4c2f01c3397c7aed;p=deliverable%2Flinux.git

sched: convert struct root_domain to cpumask_var_t, fix

Mathieu Desnoyers reported this build failure on powerpc:

 kernel/sched.c: In function 'sd_init_NODE':
 kernel/sched.c:7319: error: non-static initialization of a flexible array member
 kernel/sched.c:7319: error: (near initialization for '(anonymous)')

this happens because .span changed to cpumask_var_t, hence
the static CPU_MASK_NONE initializers in the SD_*_INIT
templates are not type-correct anymore.

Remove them, as they default to empty anyway.

Also remove them from IA64, MIPS and SH.
