mm/vmalloc: Add empty headers and use them from

2019-12-10T09:12:55+00:00

In the x86 MM code we'd like to untangle various types of historic header dependency spaghetti, but for this we'd need to pass to the generic vmalloc code various vmalloc related defines that customarily come via the low level arch header. Signed-off-by: Ingo Molnar

sched/rt, hexagon: Use CONFIG_PREEMPTION

2019-12-08T13:37:33+00:00

CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT. Both PREEMPT and PREEMPT_RT require the same functionality which today depends on CONFIG_PREEMPT.
